DANGER
DO NOT store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other
appliance.
WARNING
Improperinstallation,adjustment,alteration,serviceormaintenancecancausepropertydamage,personal
injury or loss of life. Failure to follow all instructions in the proper order can cause personal injury or
death. Read and understand all instructions, including all those contained in component manufacturers
manuals which are provided with the appliance before installing, starting-up, operating, maintaining or
servicing this appliance. Keep this manual and literature in legible condition and posted near appliance
for reference by owner and service technician.
This boiler requires regular maintenance and service to operate safely. Follow the instructions contained
in this manual. Installation, maintenance, and service must be performed only by an experienced, skilled
and knowledgeable installer or service agency. All heating systems should be designed by competent
contractors and only persons knowledgeable in the layout and installation of hydronic heating systems
should attempt installation of any boiler. It is the responsibility of the installing contractor to see that all
controls are correctly installed and are operating properly when the installation is completed. Installation
is not complete unless a pressure relief valve is installed into the specified tapping located at the rear of
appliance - See Section III of this manual for details.
This boiler is suitable for installation on combustible flooring. Do not install boiler on carpeting. Do not
operate on floors where heat affected material is below.
Do not tamper with or alter the boiler or controls. Retain your contractor or a competent serviceman to
assure that the unit is properly adjusted and maintained.
Clean boiler at least once a year - preferably at the start of the heating season to remove soot and scale.
The inside of combustion chamber should also be cleaned and inspected at the same time.
Have Burner and Controls must be checked at least once a year or as may be necessitated.
Do not operate unit with jumpered or absent controls or safety devices.
Do not operate unit if any control, switch, component, or device has been subject to water.
Returnwatercannotbelowerthanꢀꢁ5°Fforprolongedperiodsoftime. Operationundertheseconditionswill
result in sustained condensing within the combustion chamber and potentially reduce boiler longevity.
In addition, the return water cannot be introduced into the boiler if it is more than 40°F less than the idle
boiler temperature. Continued operation under these conditions may result in premature boiler failure
through thermal shock.
Example: A boiler that has been idle for some time since the last heat demand cycle may have it’s boiler
water temperature reduced to ꢀ50°F. The return temperature from the next zone activation cannot be
less than ꢀꢀ0°F.
If the above conditions exist, an RTC (or similar type of control) system must be installed to protect
the boiler from sustained condensing operation and thermal shock. See separate RTC Manual, P/N
8ꢀ46ꢁ82.

WARNING
Appliance materials of construction, products of combustion and the fuel contain alumina, silica, heavy
metals, carbon monoxide, nitrogen oxides, aldehydes and/or other toxic or harmful substances which
can cause death or serious injury and which are known to the state of California to cause cancer, birth
defects and other reproductive harm. Always use proper safety clothing, respirators and equipment when
servicing or working nearby the appliance.
This boiler contains very hot water under high pressures. Do not unscrew any pipe fittings nor attempt
to disconnect any components of this boiler without positively assuring the water is cool and has no
pressure. Always wear protective clothing and equipment when installing, starting up or servicing this
boiler to prevent scald injuries. Do not rely on the pressure and temperature gauges to determine the
temperature and pressure of the boiler. This boiler contains components which become very hot when
the boiler is operating. Do not touch any components unless they are cool.
This appliance must be properly vented and connected to an approved vent system in good condition.
Do not operate boiler with the absence of an approved vent system.
This boiler needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.
The interior of the venting and air intake systems must be inspected and cleaned before the start of the
heating season and should be inspected periodically throughout the heating season for any obstructions.
Clean and unobstructed venting and air intake systems are necessary to allow noxious fumes that could
cause injury or loss of life to vent safely and will contribute toward maintaining the boiler's efficiency.
This boiler is supplied with controls which may cause the boiler to shut down and not re-start without
service. If damage due to frozen pipes is a possibility, the heating system should not be left unattended in
cold weather; or appropriate safeguards and alarms should be installed on the heating system to prevent
damage if the boiler is inoperative.
This boiler is designed to burn No. 2 fuel oil, natural and/or LP gas only. Do not use gasoline, crankcase
drainings, or any oil containing gasoline. Never burn garbage or paper in this boiler. Do not convert to
any solid fuel (i.e. wood, coal). Do not convert to any gaseous fuel (i.e. natural gas, LP). All flammable
debris, rags, paper, wood scraps, etc., should be kept clear of the boiler at all times. Keep the boiler area
clean and free of fire hazards.
Always keep the oil supply valve shut off if the burner is shut down for an extended period of time.
Probe and float type low water cutoff devices require annual inspection and maintenance. Refer to
instructions in Section V, Paragraph C for inspection and cleaning instructions.
NOTICE
All V9A Series cast iron boilers are designed, built, marked and tested in accordance with the ASME Boiler
and Pressure Vessel Code, Section IV, Heating Boilers. An ASME Data Label is factory applied to each V9A
jacket, which indicates the boiler Maximum Allowable Working Pressure (MAWP). Each cast iron section is
permanently marked with the MAWP listed on the boiler’s ASME Data Label. Those values for the V9A are as
follows:
MAWP, Steam - ꢀ5 psi
MAWP, Water (USA) - 80 psi
MAWP, Water (Canada) - 45 psi
It is common and acceptable practice to install these boilers in lower pressure systems, below the boiler
MAWP. Therefore, Burnham offers safety relief valves set at or below the MAWP of the boiler. See Table ꢀ for
available safety relief valve set pressures.

WARNING
When a V9A gas fired boiler is connected
to a venting system that is designed so that
it will operate under a positive pressure,
manufactured vent systems, designed and
approved for positive pressure application per
ULꢀꢂꢁ8,mustbeused(forexample,Van-Packer
model CS, Protech Model FasNSeal / FasNSeal
W2, Heatfab Saf-T-Vent or equivalent).
When a V9A oil fired or combination gas/oil
fired boiler is connected to a venting system
that is designed so that it will operate un-
der a positive pressure, manufactured vent
systems, designed and approved for posi-
tive pressure application, must be used (for
example, Selkirk Metalbestos Model PS / IPS,
Van-Packer Model ES or equivalent).
Figure ꢁa: Typical Arrangement for Stub Vent
If the venting system is designed for positive or forced
draft venting, the boiler, vent connector and stack will
operate under positive pressure. Gas tight vent systems
designed for pressure systems must be used to prevent
flue by-product leakage. The vent height is usually
limited to prevent negative draft, typically three (3)
feet above the roof line (see Figure 3a). The damper
shall be adjusted to maintain a positive pressure of
0.1” W.C. in the vent connector box during burner high
fire operation (see breeching pressure sensing port in
Figure 1).
The V9A Series boiler is designed for forced draft
firing and may be used with a conventional natural draft
stack (15’ minimum height) or a stub vent, sometimes
called a diesel stack (see Figure 3a). See Table I for
the proper vent outlet size. For low silhouette vent
terminations, see Figure 3b. Draft controls are not
normally required, although they may be used on
installations where a natural draft stack is used or on
multiple boiler installations with a common stack. The
boiler is provided with a breeching damper, which
should be adjusted to maintain a positive pressure of
0.1” W.C. in the vent connector box during burner high
fire operation (see breeching pressure sensing port in
Figure 1).
If the venting system is designed for negative pressure
(natural draft), the boiler still operates with positive
pressure in the chamber and up to the fixed damper on
the flue collar. However, if the venting system is larger
than what is required, the stack will provide a surplus
draft (or negative pressure) that may require the use of
a barometric damper to maintain the positive 0.1” W.C.
pressure at the flue outlet. Multiple forced draft boiler
stacks should always be designed as negative to ensure
the products of combustion do not exit a boiler that is
not firing.
WARNING
Venting instructions are recommendations only. Consult a venting expert on the design of a specific
vent system for your application. The ASHRAE Venting Guide and The National Fuel Gas Code, NFPA
54 should be considered in all venting systems.
Conventional vent material may not be suitable for the application. Flue gases can leak carbon
monoxide from the joints on these materials and can result in severe personal injury or death.
Installations having long horizontal runs or an excessive amount of tees or elbows will restrict the flow
of combustion gases and can result in condensation, flue gas leakage of carbon monoxide, resulting in
severe personal injury or death.

FAULTY BOILER BURNER OPERATION
1. If improper vent is suspected, remove pipe at breeching and operate boiler. This will determine if excessive down draft,
blocked or restricted flue, etc. is causing the problem.
2. If using type shown in A above, be sure cap is raised sufficiently above main pipe to allow flue gases to vent unimpeded.

SECTION II - CAST IRON BLOCK ASSEMBLY
A. FACTORY ASSEMBLED SECTIONS — If the
boiler was ordered with factory assembled sections,
the assembly should be set in the proper location as
outlined in Section I. Lifting arrangement and weights
are given in Figure 4.
1. Proceed to Paragraph C of this Section,
“HYDROSTATIC TEST”.
CAUTION
Boiler sections must be drawn-up on perfectly
level surface or improper assembly may result.
B. FIELD ASSEMBLED SECTIONS — If the boiler
was ordered to be field assembled, follow the assembly
procedure outlined on the following pages.
1. ASSEMBLY OF SECTIONS (MANUAL DRAW-
UP)
These sections are designed to be drawn together,
one section at a time, using the 9¾” long draw-up
rods (provided) and ordinary hand tools.
Figure 5: Positioning of Back Section
Tools required:
(1) ¾” Drive Ratchet
(1) 1-1/16” Socket
b. On size V903A only— Open target wall carton,
apply Silastic to back of target wall and secure
target wall to rear section.
(1) 1-1/16” Combination or Open End Wrench
(1) Container of grease, oil or other appropriate
lubricant.
c. Clean the groove in the ground joint along the
edge of the section with the wire brush.
d. Open the Boiler Assembly Carton(s) and remove
the bottle of adhesive. Using the dauber supplied
in the bottle, apply the adhesive to the groove.
Be sure to use enough adhesive to sufficiently
coat the entire groove surface. If so desired,
a multi-purpose spray adhesive (supplied by
others) may be used instead. HOWEVER,
GREAT CARE MUST BE TAKEN TO
ENSURE THAT THE ADHESIVE DOES
NOT COME IN CONTACT WITH THE
NIPPLES OR NIPPLE PORTS.
CAUTION
When assembling sections without hydraulic
draw-up equipment, never assemble more than
one section at a time.
a. Place the rear section in its approximate final
position, as outlined in Section I, and support it
with a suitable prop and wedges. See Figure 5.
e. While the adhesive is becoming tacky, clean
nipples and nipple ports thoroughly with a de-
greasing solvent. Use the Loctite #592 provided
to lubricate the nipples and nipple ports. Apply
the lubricant to the nipples and nipple ports,
then use a brush to disperse it evenly around the
nipples and the nipple ports. Use approximately
25 ml of Loctite #592 per flueway [(1) 7” and
(2) 3” nipples and their (6) corresponding nipple
ports].
f. Drive nipples squarely into section using
block of wood and hammer, or preferably, an
aluminum head hammer. (Burnham offers a
Polyethylene Block for setting the nipples, part
number 8052601). Place block over entire
nipple edge and hit the wood with the hammer.
Figure 4: Lifting Instruction
ꢀ4
WARNING
Nipples must be driven in evenly and to the
proper depth to assure tight joints. Most
nipple leaks are caused by tilted or cocked
nipples.
DO NOT use steel/iron head hammer to drive
nipples without using a wood block. Nipple
damage may result.
g. A special nipple setting gauge is provided for the
nipples. Gauge nipple at 90° angles to insure
that it is driven to the proper depth into the
nipple opening (nipple port). Cut-out in gauge
must rest on nipple, with legs of gauge touching
finished face of section, when nipple is properly
driven. See Figure 6.
Figure 7: Affixing the Fiberglass Rope
NOTICE
The sections must be assembled according to the
arrangement shown to ensure proper operation,
proper assembly of canopy, jacket and alignment
of piping and tankless heaters with jacket
knockouts. Start with the back section and work
towards the front.
i. From the “Section Arrangement” chart, select
the next section according to the “Identification
Code” at the top of the chart. See Figure 8. Use
a wire brush to clean the groove in the face
of the next section. Then, using a cartridge of
RTV 6500 or RTV 736 sealant in a caulking gun,
fill the groove in this section with silastic sealant.
Touch-up any missed spots before draw-up.
Touch-up after draw-up has no value.
Figure 6: Setting of Nipples
h. Remove a 96” length of fiberglass rope from
the assembly carton. Starting with the area
around the upper 7” nipple port, firmly press
the rope into the groove, so that the adhesive
holds it in place. (If more than 25 minutes have
passed since the adhesive was applied, it may
be necessary to reapply.) Continue to affix the
rope to the groove in this fashion around the
perimeter of the section. Make sure that the rope
does not droop or hang outside of the groove.
When the end of the groove is reached, cut off
the excess rope. Push the length of excess rope
into the groove at the top corner of the section
face (opposite of the 7” nipple port.) Cut off and
discard any remaining rope after groove is filled.
See Figure 7.
WARNING
Sections must be drawn-up tight immediately
afterproperlyapplyingsealantforbestresults.
Although sections may be joined within two
(2) hours of applying sealant, humidity and
temperature affect cure time. If a “thick skin”
has been formed on the sealant bead, remove
and re-apply sealant.

NOTES: FOR BOILERS LESS TANKLESS HEATER, REPLACE THE "CT" SECTIONS WITH "C" SECTIONS.
Figure 8: V9A Section Arrangement
j. Clean and lubricate nipple ports on next section
to be assembled and place on nipples previously
installed in rear section. To facilitate assembly,
it is advisable to enter the upper nipple first in
its port. Then enter the lower nipples in their
respective ports. If necessary, place a lifting bar
(crowbar) under the center of the section and lift
the nipple port onto the upper nipple.
m. DRAW UP SECTION SLOWLY AND
EVENLY using an alternating pattern starting
with the upper right lug (closest to the 7” port)
and proceeding to the lower left , lower right
and finishing with upper left lug. When you
start, grind surfaces between adjoining sections
should be approximately 3/8” apart. Use
three (3) or four (4) passes at tightening the
four (4) draw-up rods a little at a time so that
sections are pulled up evenly. During the last
pass, pay close attention to the silastic sealant
as it squeezes when the sections come in close
contact. The silastic sealant should continue
to squeeze out wafer thin until the sections are
connected metal to metal. If the silastic has
stopped squeezing out from the connection and
the sections still do not appear to be drawn metal
to metal, use a feeler gauge to measure any gaps
at the locations identified in Figure 9. (Unless
specified otherwise, gaps should be measured at
these locations on both sides of the sections.) A
maximum gap of .025” is acceptable. Measure
gaps at the outer edge of the connection only,
making sure not to puncture the gasket created
by the silastic and rope.
k. Drive sections in place with a heavy block of
wood, striking blows as squarely as possible over
nipple port.
l. The large draw-up rod lugs with dual holes
are cast in the four (4) corners of each casting.
STARTING WITH THE UPPER HOLES,
install four (4) 5/8” x 9¾” long draw-up rods
along with washers and nuts (see Figure 9).
CAUTION
To avoid damage to the draw-up rod threads while
drawing up sections, apply oil or other lubricant
to tie rod threads while assembling sections to
prevent stripping of threads on rod and to make
assembling easier.
ꢀ6
p. EXCESS LENGTH OF DRAW-UP RODS must
not extend beyond front and rear section to
ensure proper fit of jacket, adjust accordingly.
q. After all sections have been drawn up, the
draw-up rod nuts should be loosened until
finger tight and then tightened ½ turn with a
wrench.
r. Now Proceed to Paragraph C of this Section,
Hydrostatic Test.
2. ASSEMBLY OF SECTIONS (HYDRAULIC
DRAW-UP)
The entire boiler assembly may be drawn up at one
time using hydraulic draw-up equipment providing
the operation is completed within two (2) hours after
application of the sealant.
a. Repeat steps 1a through 1k under “Field
Assembled Sections (Manual Draw-Up).”
b. Continue driving sections in place (in their
respective order) until all sections are in the
assembly. Ground surfaces between adjoining
sections should be spaced 1/4” to 3/8” apart.
Spacing of more than 3/8” will limit number of
sections that can be drawn up in one unit and
could indicate cocked nipples.
Figure 9: Connection Inspection Locations and
Manual Draw-Up Tie Rod Pattern
WARNING
When tightening the draw-up nuts, DO NOT
EXCEED ꢀ50 FT-LB OF TORQUE. If the maximum
torque limit has been reached and a gap greater
than .025” still exists between the sections,
consult the regional office.
WARNING
Sealant must be properly applied to ALL boiler
joints. Failure to properly seal the boiler joints
will result in combustion gas leaks through to
joint. DO NOT operate boiler with combustion
gas leaks. The sealant should be applied before
each section is placed on the assembly.
KEEP NIPPLES ALIGNED WITH NIPPLE
PORTS. If necessary, tap edge of nipples lightly
with a blunt tool or rod to keep nipples from
cocking while sections are being drawn-up. DO
NOT DRAW UP SECTION WHEN NIPPLES
ARE COCKED. If the torque required becomes
excessive, periodically place a heavy block of
wood over each nipple port and strike as squarely
as possible with several blows to relieve tension
on the draw-up rods.
On long boiler assemblies, it may be necessary to
draw-up a partial block if the entire boiler is not
ready to be drawn-up tight within two (2) hours
of the first application of Silastic. If the block
assembly time extends overnight, the partial
block completed must be drawn-up tight before
leaving the boiler overnight. If a joint springs
out, it must be redrawn tight within four (4)
hours of first application of Silastic to the joint.
n. CONTINUE ASSEMBLING SECTIONS IN
THEIR RESPECTIVE ORDER alternating
draw-up rods from the upper to lower set of
holes in draw-up lugs (see Figure 13). Be certain
that all sections are drawn up iron-to-iron at all
three (3) nipple ports.
c. Insert the three (3) ¾” draw-up rods (and
couplings, if appropriate) through the tapped
holes in the rear section extending them through
the tapped holes in the front section. Be sure to
screw draw-up rods into couplings far enough to
prevent stripping threads.
BE SURE TO APPLY THE SEALANT to
the groove in the ground joints between
adjacent sections as the boiler operates with a
positive pressure in the firebox and products of
combustion will escape between sections unless
the sections are properly sealed. The sealant
should be applied before each section is placed
on the assembly.
d. Place a 3” x 12” lg. steel channel on each end of
the upper draw-up rod and a 3” x 8½” lg. steel
channel on each end of the lower draw-up rods.
Refer to Figures 10 and 11 for proper placement
of channel block during assembly procedures.
Install nuts and washers on one end of the draw-
up rods and the hydraulic rams, washers and
o. If a joint springs apart it must be redrawn tight
within four (4) hours of the time of application of
Silastic to that joint.
ꢀꢂ
draw-up rod clamps on the other. These items
are all located in the Draw-Up Kit.
See Figure 12.
CAUTION
Do not apply pressure directly on threaded
tappings on front and rear sections with draw-up
channels during assembly procedures.
Rods should be approximately centered in
openings so that rods and couplings (when
used) do not drag on pipe thread in end section
tappings.
WARNING
READ THE STATEMENTS BELOW BEFORE
ATTEMPTING TO USE HYDRAULIC EQUIPMENT.
• Release pressure in ram pumps before
attempting to remove clamps.
• Do not stand in line with draw-up rods at either
end when hydraulic pressure is being applied.
As a safety measure, ends of draw-up rods
should be covered while sections are being
drawn in case rods should snap while under
tension.
Figure ꢀꢀ: Center Section Channel Block Position
(Partial Block Draw-Up)
The large draw-up rod lugs with dual holes cast
in the four (4) corners of each casting. Starting
with the upper holes in the back section, install
four (4) 5/8” x 9¾” long tie rods along with
washers and nuts. Continue installing the tie
rods alternating from the upper to lower set
of holes in draw-up lugs until front section is
secured. Be certain that all sections are drawn
up IRON TO IRON at all three nipple ports.
• Do not operate ram against draw-up coupling.
• Do not operate pump after ram has reached
stroke limit.
h. Excess length of draw-up rods must not extend
beyond front and rear section to ensure proper fit
of jacket, adjust accordingly. Tighten all tie rod
nuts until finger tight. Then tighten them an
additional ½ turn with a wrench.
C. HYDROSTATIC TEST — After the boiler sections
have been assembled, it is essential that the boiler be
hydrostatically tested before the canopy, flue cover
plates, jacket, or piping is installed.
1. Tankless Heater Installation
If boiler is ordered with tankless heaters, install
heaters with the gaskets provided. Table IV gives
the maximum number of heaters permissible per
assembly and the heater ratings.
Figure ꢀ0: Front and Rear Section Channel
Block Positions (Hydraulic Draw-Up)
e. Draw-Up Sections
2. Plug all boiler tappings and fill boiler completely
Use hydraulic rams to draw up sections by
applying pressure alternately on the draw-up
rods. When rams reach stroke limit, release
pressure in ram pumps and then move clamps to
new position.
with cold water.
CAUTION
DO NOT install gauge until after hydrostatic
testing the boiler. Gauge failure may result.
f. Continue to draw-up until all sections make
contact at the ground joints.
3. All completed boilers must satisfactorily pass the
prescribed hydrostatic test.
g. After all sections have been drawn up, but before
removing the hydraulic rams and draw-up rods,
the 9¾” long tie rods must be installed.
ꢀ8
Figure ꢀ2: Hydraulic Draw-Up Sections
a. STEAM BOILERS: The assembled boiler must
be subjected to a hydrostatic test of 45 psig to 55
psig.
b. HOT WATER BOILERS: The assembled boiler
must be subjected to a hydrostatic test of not less
than 1½ times the maximum allowable working
pressure, as established by the relief valve
provided with the boiler. For example, a boiler
with a 50 psi relief valve must be subjected to a
test pressure of 75 psig to 85 psig.
WARNING
Failure to properly hydrotest all boilers at the
correct pressure may result in section assembly
failure in operation.
4. EXAMINE BOILER CAREFULLY, INSIDE AND
OUTSIDE, to insure against leaks from cocked
nipples or through concealed breakage caused in
shipping and handling. This precaution is for your
protection and will simplify handling of necessary
replacements and adjustment claims.
5. After making certain that there are no leaks, drain
boiler and remove plugs for boiler trim and other
connections.

pipe in any area where freezing could occur. Do
not install any shut-off valves, plugs or caps in
discharge piping.
4. Level the pressure limit control by carefully bending
the syphon until the control’s leveling indicator
hangs freely with its pointer directly over the index
mark inside the back of the case.
5. Install the steam gauge using the ½” NPT x ¼” FPT
hex bushing.

instructions may void manufacturer’s warranty.
Also consult I=B=R Installation and Piping Guides.
Connect supply and return piping to heating system (see
Figures 26 through 32). Flow direction for hot water
boilers must be from the rear return out through the top
front supply. Steam boilers can pipe return to the front
as an alternate location. Some boiler sizes may require
the use of additional supply and return tappings. Check
Figure 24 and applicable piping diagram for the boiler
size you are installing.
WARNING
Continued boiler operation for prolonged periods
of time under conditions when temperature
differential across the system exceeds 40°F and/
or, return water temperature stays below ꢀꢁ5°F,
may result in premature boiler failure due to flue
gas condensation and/or thermal shock.
WARNING
Failure to properly pipe boiler may result in
improper, unsafe system operation and void
manufacturer’s warranty.
a. If the boiler is used in connection with
refrigeration systems, boiler must be installed
with chilled medium piped in parallel with
heating boiler using appropriate valves to prevent
chilled medium from entering boiler. See Figure
35.
DO NOT improperly pipe boiler.
WARNING
b. If the boiler is connected to heating coils
located in air handling units where they may be
exposed to refrigerated air, boiler piping must
be equipped with flow control valves to prevent
gravity circulation of boiler water during cooling
system operation.
All steam and hot water pipes must have
clearances of at least ꢀ/2” from all combustible
construction.
WARNING
c. Burnham Commercial recommends maintaining
temperature differential (drop) across the system
at 40°F or less, and return water temperature at
minimum of 135°F for optimum operation and
long-term reliability.
A hot water boiler installed above radiation level
must be provided with a low water cutoff device
as part of the installation.

f. Glycol Antifreeze Solutions - Many systems
today use ethylene or propylene glycol antifreeze
solutions as a measure for freeze protection, as
well as a pump lubricator and corrosion inhibitor.
The properties of the glycol mixture have an
impact on valve and pump sizing. All glycol
solutions have a lower specific heat than water.
This means that the glycol solution cannot
transfer heat as well as pure water, resulting in
the need for higher flow rates. In addition, the
viscosity of the glycol solution is usually higher
than water, requiring a higher pump head for the
same given flow. Consult factory for specific
applications, pump selection and flow rate.
recommended minimum boiler piping
details.
ii. If minimum return water temperature cannot
be maintained at 135°F or the temperature
differential across the system varies, a blend
pump is recommended as a minimum to help
protect the boiler from flue gas condensation
and/or thermal shock. See piping details in
Figure 28. Primary secondary piping with
a by-pass is an alternate to the blend pump
method and is shown in Figure 29.
d. If conditions exist where the boiler is subjected
to prolonged periods of operating conditions
below 135°F, other mixing methods such as three
or four way valves or variable speed injection
should be used. Burnham Commercial offers an
RTC Return Temperature Control kit to protect
the boiler. See separate RTC manual.
WARNING
A properly constructed Hartford Loop must be
installed on all gravity return steam systems.
Hartford Loop is not required on pumped return
systems.
e. Multiple Boilers - Recommended minimum
multiple boiler piping is shown in Figure 30 as
primary secondary with a by-pass. The boiler
circulator will maintain a constant flow through
the boiler during every heat demand while the
by-pass diverts a portion of hot water back to
the return. Alternate minimum multiple boiler
piping is shown in Figure 31. The blend pump

applications, such as hotel showers and laundries.
See Figure 37b for recommended piping and wiring
details for this type of application. The tempering
valve and recirculation loop are advantageous in
these applications, because they provide both high
temperature and tempered domestic hot water to
the system, eliminating the need to purge and waste
water until it reaches the desired temperature. In
the case where the boiler is used for domestic
production only, and there is no space heating
involved, a destratification pump is utilized to
provide flow within the boiler. This flow acts as a
means of preventing the hot water from stratifying
at the top of the boiler. Destratification pump flow
rates are given in the table in Figure 37b.
M. BOILER PIPING, DOMESTIC HOT WATER
(DHW) APPLICATION – The V9A boiler can be
used in many different piping applications to produce
Domestic Hot Water (DHW). In some applications,
depending on the control strategy (outdoor reset,
setpoint operation, etc.) and size of boiler, it is
recommended to isolate the space heating load from
the DHW load. For example, if the domestic load is
more than the space heating load, it is beneficial to
dedicate one or more boilers solely to DHW production
and one or more other boilers to solely space heating,
since during mild weather conditions, the boiler(s)
will have more capacity than is required. Piped in the
recommended manner, the space heating boiler(s) can
be shut down during the summer months to conserve
energy and to avoid short cycling. This section
will address four methods of piping and controlling
domestic hot water generation.
3. Hot Water Boiler/Indirect Water Heater - The use
of indirect water heaters for domestic hot water
generation is common and somewhat advantageous
over tankless coils alone, since they also provide
DHW storage. A tempering valve and recirculating
pump are again recommended for a dual temperature
system, to provide a constant temperature to the
fixtures without waiting for cooler water to warm
up. Figure 37c shows a typical indirect heater
piping application with no space heating. Indirect
pump flow rates are calculated based on a 20°F DT.
1. Hot Water Boiler/Tankless Coil(s) - Tankless
coils, mounted into the side of the boiler, have
been used successfully for many years and may
be used in single and multiple boiler applications.
When a boiler is arranged with tankless coils, it
is not recommended that outdoor reset be used,
unless there are control systems in place to prevent
overheating of the space heating zones.
Figure 37a depicts the addition of an automatic
mixing valve to the tankless heater piping to obtain
a dual temperature domestic system. The mixing
valve provides tempered water to the fixtures,
while the branch prior to the valve provides high
temperature water for dishwashing, washing
machines and other appliances.
NOTICE
DO NOT use the boiler circulator as an indirect
domestic hot water system circulator.
4. Steam Boiler/Indirect Water Heater – Consult
I=B=R Installation and Piping Guide No. 200. Use
the Indirect Water Supply tapping, “R” (Special
Order Only – see Figure 24) when connecting an
Indirect Water Heater directly to the boiler.
2. Hot Water Boiler/Tankless Coils/Storage Tank - This
application involves the use of several tankless coils
piped in parallel, emptying into a large storage tank,
and is typically used in larger DHW production
NOTICE
When possible, domestic hot water production should utilize a dedicated boiler(s). This will allow the other
boiler(s) to be shut down and isolated during the summer months. If the boiler load is shared between
heating and domestic hot water, then one needs to determine if a hot water priority is required. If a priority
is not selected, erratic domestic hot water production may result during the beginning and end of every
heating season. Conversely, a priority for domestic hot water production may cause a significant heating
zone activation delay, in an improperly balanced system. Parallel piping conversions may require isolation
from the heating system to prevent system flow influence on DHW performance. Consult a qualified system
heating professional to design for the proper application.
ꢁ9
N. CONNECT TANKLESS HEATER PIPING as
shown in Figure 37a. See Table IV for Tankless Heater
Ratings.
NOTICE
The following guidelines should be followed when
piping the tankless heater:
1. Install Flow Regulator
If flow through the heater is greater than its rating,
the supply of adequate hot water may not be able to
keep up with the demand. For this reason a FLOW
REGULATOR matching the heater rating should be
installed in the cold water line to the heater. Refer
to Figure 37a for piping recommendations. Locate
the flow regulator below the inlet (cold water side)
of the heater and a minimum of 36” away from the
inlet so that the regulator is not subjected to excess
temperatures during “off” periods when it is possible
for heat to be conducted back through the supply
line. The flow regulator will limit the flow of supply
water regardless of inlet pressure variations ranging
from 20 to 125 psi.
Figure ꢁ5: Recommended Piping for Combination
Heating & Cooling (Refrigeration) Systems
Water Boilers
water will be achieved since the user will not waste
as much hot water while seeking desired water
temperature. Higher temperature hot water required
by dishwashers and automatic washers is possible
by piping the hot water from the heater prior to
entering the mixing valve. An electric hot water
booster can also be used. The mixing valve should
be “trapped” by installing it below the cold water
inlet to heater to prevent lime formation in the valve.
2. Install Water Temperature Mixing Valve
WARNING
Install a mixing valve at the tankless heater
outlet to avoid risk of burns or scalding due to
excessively hot water at fixtures. Do not operate
the boiler when equipped with a tankless heater
unless mixing valve is operating properly.
3. Flushing of Heater
All water contains some sediment which settles
on the inside of the coil. Consequently, the heater
should be periodically backwashed. This is
accomplished by installing hose bibs as illustrated
in Figure 37a and allowing water at city pressure to
run into hose bib A, through the heater, and out hose
bib B until the discharge is clear. The tees in which
the hose bibs are located should be the same size as
heater connections to minimize pressure drop.
Refer to Figure 37a for piping recommendations.
Adjust and maintain the mixing valve in accordance
with manufacturers instructions.
Installation of a mixing valve will also lengthen the
delivery of the available hot water by mixing some
cold water with the hot. In addition, savings of hot
4. Hard Water
A water analysis is necessary to determine the
hardness of your potable water. This is applicable
to some city water and particularly to well water.
An appropriate water softener should be installed
based on the analysis and dealer’s recommendation.
This is not only beneficial to the tankless heater but
to piping and fixtures plus the many other benefits
derived from soft water.
CAUTION
Do not operate tankless heater with hard water.
Tankless failure will result. Install water softener
if hard water is present.

on the Boiler Rating Label.
Failure to clean the system will result in erratic
water lines and surging, and other improper
system operations.
DO NOT draw water from boiler while in
use. When adding water while boiler is in
operation, do not open supply valve fully
but add water slowly.
CLEAN HEATING SYSTEM IF boiler water or
condensate return water is dirty or if erratic water lines
or surging exist after a few days of boiler operation.
Refer to Paragraph (F) for proper cleaning instructions
for steam and water boilers.
1. STEAM BOILERS - Fill boiler to normal water
line. As shown in Figure 1, the normal water line
is 41½” from the floor or bottom of casting. At
the start of each heating season and once or twice
during the season try SAFETY VALVE to be sure it
is in working condition. To do this, fasten wire or
cord to lever of valve and pull lever — standing safe
distance away from valve.
C. SET CONTROLS with burner service switch turned
“OFF”.
1. PRESS RESET BUTTON on primary control and
release.
2. On STEAM BOILERS set cut-in pressure on
L404A Pressuretrol for three (3) PSI and differential
pressure for two (2) PSI. These pressures may be
varied to suit individual requirements of installation.
2. HOT WATER BOILERS - Fill entire Heating
System with water and vent air from system. Use
the following procedure on a Series Loop or Multi-
zoned System to remove air from system when
filling:
3. On STEAM BOILERS WITH TANKLESS
DOMESTIC WATER HEATERS, set boiler water
temperature dial on low limit operating control at
190°F (max.). Set differential at 10°.

4. CHECK OPERATING CONTROL on boiler
equipped with tankless heaters. With burner off,
draw hot water until burner starts, then turn off hot
water and check burner shutdown.
F. BOILER AND SYSTEM CLEANING - STEAM
BOILER
D. ADJUST BURNER according to the Burner Manual.
1. FLAME FAILURE
The V9A boiler controls operate the burner
automatically. If for unknown reasons the burner
ceases to fire and the reset button on the primary
control is tripped, the burner has experienced
ignition failure. Before pressing the reset button,
call your serviceman immediately.
NOTICE
A qualified water treatment chemical specialist
should be consulted for recommendations
regarding appropriate chemical compounds and
concentrations which are compatible with local
environmental regulations.
WARNING
Do not attempt to start the burner when excess
oil or gas has accumulated in the combustion
chamber, when the unit is full of vapor, or when
the combustion chamber is very hot.
WARNING
Chemicals used in treating boiler water are
toxic and/or harmful. Always use protective
clothing and equipment when working with/
near chemicals. Contact local authorities
to determine if treated boiler water can be
discharged into local waste water system.
E. TEST CONTROLS
WARNING
1. Oil, greases & sediments which accumulate in a
new boiler and piping must be removed in order
to prevent an unsteady water line and carry over
of the water into the supply main above boiler.
Operate the boiler with steam in the entire system
for a few days allowing the condensate to return
to the boiler. If the condensate can temporarily be
wasted, operate boiler only for the length of time
it takes for condensate to run clear. If the latter
cannot be achieved or if the condensate is returned
to the boiler, boil out the boiler using the SURFACE
BLOWOFF connection. See Figure 38a.
Before installation of the boiler is considered
complete, the operation of the boiler controls
should be checked, particularly the low water
cutoff and the high limit control.
All controls must be checked prior to putting the boiler
in service.
1. CHECK OPERATING CONTROL OPERATION.
Raise and lower operating control setting as required
to start and stop burner.
2. CHECK OPERATION OF HIGH LIMIT
CONTROL —
a. Drain boiler until water is just visible in gauge
glass. Run temporarily 1½” pipe line from the
surface blowoff connection to an open drain or
some other location where hot water may be
discharged safely. Do not install valve in this
line.
Jumper Operating Control Terminals. Allow burner
to operate until shutdown by limit. Installation is
not considered complete until this check has been
made. REMOVE JUMPER.
3. CHECK LOW WATER CUTOFF control with water
level at normal water line (see Figure 1). Raise
operating control setting to allow burner to operate.
Open boiler drain to allow water level to drop to
bottom of sight glass until burner operation is shut
down by low water cutoff.
b. Add an appropriate amount of recommended
boilout compounds.
c. Start burner and operate sufficiently to boil
the water without producing steam pressure.
Boil for about 5 hours. Open boiler feed pipe
sufficiently to permit a steady trickle of water
from the surface blowoff pipe. Continue this
slow boiling and trickle of overflow for several
hours until the water coming from the overflow
is clear.
Close boiler drain and refill to normal water line.
Burner should automatically restart during fill.
RESET OPERATING CONTROL.
46
d. Stop burner and drain boiler in a manner and to
a location that hot water can be discharged with
safety.
if this sample is not clear, repeat the cycle of
draining the boiler and return main and refilling
the boiler until sample is clear.
e. Refill boiler to normal water line. If water in
gauge glass does not appear to be clear, repeat
steps (a. thru e.), and boil out the boiler for a
longer time.
f. If the boiler water becomes dirty again at a later
date due to additional sediment loosened up in
the piping, close gate valve in Hartford Loop,
open drain valve in return main, turn on burner
and allow condensate to flow to drain until it has
run clear for at least 30 minutes while feeding
water to boiler so as to maintain normal water
level. Turn off burner, drain boiler, open gate
valve in Hartford Loop, then repeat step (1)
above.
2. Low pressure steam boilers such as the V9A Series
should be maintained with appropriate water
treatment compounds. After cleaning process has
been completed, add water treatment compounds
as recommended by your local qualified water
treatment company.
5. Make pH or Alkalinity Test.
3. Remove temporary surface blowoff piping and
replug tapping. Boil or bring water temperature to
180°F promptly in order to drive off the dissolved
gases in the fresh water.
After boiler and system have been cleaned and
refilled as previously described, test the pH of the
water in the system. This can easily be done by
drawing a small sample of boiler water and testing
hydrion paper which is used in the same manner
as litmus paper, except it gives specific readings.
A color chart on the side of the small hydrion
dispenser gives the reading in pH. Hydrion paper
is inexpensive and obtainable from any chemical
supply house or through your local druggist. The
pH should be higher than 7, but lower than 11. Add
some appropriate water treatment chemicals, if
necessary to bring the pH within the specified range.
4. If unsteady water line, foaming or priming persist,
install gate valve in Hartford Loop and drain valves
in return main and at boiler and proceed as follows:
a. Connect hoses from drain cocks to floor drain.
Close gate valve in Hartford Loop and open
drain valve in return main. Fill boiler to normal
water level, turn on burner and operate boiler
at this water level for at least 30 minutes after
the condensate begins to run hot, then turn off
burner.
6. Boiler is now ready to be put into service.
Close all radiator valves. Remove all supply
main air valves and plug the openings in supply
main.
G. BOILER AND SYSTEM CLEANING - WATER
BOILERS
b. Draw about 5 gallons of hot water from boiler
into a container and dissolve into it appropriate
amount of a recommended boilout compound.
Remove surface blowoff plug and pour this
solution into boiler, then reinstall plug.
1. Filling of Boiler and System --- General --- In a hot
water heating system, the boiler and entire system
(other than the expansion tank) must be full of water
for satisfactory operation. Water should be added to
the system until the boiler pressure gauge registers
normal system design operating pressure. To insure
that the system is full, water should come out of all
air vents when opened.
c. Turn on burner and keep operating while feeding
water to boiler slowly. This will raise water level
in boiler slowly so that water will be boiling hot
and will rise slowly into supply main and back
through return main, flowing from drain hose
at about 180°F. Continue until water runs clear
from drain hose for at least 30 minutes.
2. Boiling Out of Boiler and System. The oil and
grease which accumulate in a new hot water boiler
can be washed out in the following manner.
a. Remove safety relief valve using extreme care to
avoid damaging it.
d. Stop feeding water to boiler but continue
operating burner until excess water in boiler
flows out through supply main and water lowers
(by steaming) until it reaches normal level in
boiler. Turn off burner. Drain boiler. Open all
radiator valves. Reinstall all supply main air
valves. Open gate valve in Hartford Loop.
b. Add an appropriate amount of recommended
boilout compound.
c. Reinstall safety relief valve.
d. Fill the entire system with water.
e. Start firing the boiler.
e. When boiler has cooled down sufficiently (crown
sheet of sections are not too hot to touch), close
the drain cocks at boiler and in return main and
feed water slowly up to normal level in boiler.
Turn on burner and allow boiler to steam for
10 minutes then turn off burner. Draw off one
quart of water from bottom gauge glass fitting
and discard. Draw off another quart sample and
f. Circulate the water through the entire system.
g. Vent the system, including the radiation.
h. Allow boiler water to reach operating
temperature, if possible.
i. Continue to circulate the water for a few hours.
j. Stop firing the boiler.
4ꢂ
k. Drain the system in a manner and to a location
that hot water can be discharged with safety.
water are dissolved minerals and oxygen. When the
fresh, cool make-up water is heated in the boiler the
minerals fall out as sediment and the oxygen escapes
as a gas. Both can result in reduced boiler life. The
accumulation of sediment can eventually isolate
the water from contacting the cast iron. When this
happens the cast iron in that area gets extremely hot
and eventually cracks. The presence of free oxygen
in the boiler creates a corrosive atmosphere which, if
the concentration becomes high enough, can corrode
the cast iron through from the inside. Since neither of
these failure types are the result of a casting defect, the
warranty does not apply. The maintenance of system
integrity is the best method to prevent these types of
failure.
l. Remove plugs from all available returns and
wash the water side of the boiler as thoroughly as
possible, using a high-pressure water stream.
m. Refill the system with fresh water.
3. Add appropriate boiler water treatment compounds
as recommended by your local qualified water
treatment company.
4. Make pH or Alkalinity Test.
After boiler and system have been cleaned and
refilled as previously described, test the pH of the
water in the system. This can easily be done by
drawing a small sample of boiler water and testing
with hydrion paper which is used in the same
manner as litmus paper, except it gives specific
readings. A color chart on the side of the small
hydrion dispenser gives the reading in pH. Hydrion
paper is inexpensive and obtainable from any
chemical supply house or thru your local druggist.
The pH should be higher than 7 but lower than 11.
Add some appropriate water treatment chemicals, if
necessary to bring the pH within the specified range.
With this lower level of protection, care must be
exercised to eliminate all of the free oxygen in the
system.
I. OXYGEN CORROSION:
WARNING
Oxygen contamination of the boiler water
will cause corrosion of iron and steel boiler
components, and can lead to boiler failure.
Burnham’s standard warranty does not cover
problems caused by oxygen contamination of
boiler water or scale (lime) build-up caused by
frequent addition of water.
5. Boiler is now ready to be put into service.
There are many possible causes of oxygen
contamination such as:
IMPORTANT
a. Addition of excessive make-up water as a result
of system leaks.
IF, DURING NORMAL OPERATION, IT IS
NECESSARY TO ADD MORE WATER PER
MONTH THAN INDICATED BELOW, CONSULT A
QUALIFIED SERVICE TECHNICIAN TO CHECK
YOUR SYSTEM FOR LEAKS.
b. Absorption through open tanks and fittings.
c. Oxygen permeable materials in the distribution
system.
In order to insure long product life, oxygen sources
must be eliminated. This can be accomplished
by taking the following measures:
EXCESSIVE WATER ADDITION:
(Gal/Month)

damage the insulation.
A. GENERAL — Inspection should be conducted
annually. Service as frequently as specified in
paragraphs below. While service or maintenance is
being done, electrical power to the boiler must be “off”.
c. Using a 1¼” diameter wire or fibre bristle brush
(36” handle) clean the flueways. Start at the top
of each flueway opening and work down the pin
rows using two or three horizontal strokes per
row for best results.
B. CLEAN THE BOILER HEATING SURFACES
& FLUE at least once each year, preferably at the end
of the heating season.
1. CLEAN THE VENT SYSTEM — Vent system
should be checked annually for:
3. CLEAN TOP OF BOILER SECTIONS
a. Obstructions.
Remove the jacket top panel. Remove the top flue
canopy cover or outlet assembly. Use a flashlight to
inspect the upper portion of the flueways and top of
castings for soot and debris. Heavy accumulations
over 1/16” thick must be removed. Remove the
canopy being careful not to damage the cerafelt
strips. Brush and vacuum the upper flueways and
tops of castings.
b. Accumulations of soot.
c. Deterioration of vent pipe or vent accessories
due to condensation or other reasons.
d. Proper support — no sags, particularly in
horizontal runs.
e. Tightness of joints.
f. Remove the smoke pipe. Remove all

d. Dismount the low water cutoff control from the
probe.
Do not start the burner unless canopy, smokepipe,
burner mounting plate and all flue plates are
secured in place.
e. Unscrew the probe from the boiler tapping.
f. Inspect that portion of the probe that is exposed
to the boiler water for a scale or sediment
buildup.
a. If removed, install the canopy taking care to
align the cerafelt strips. If strips are damaged
replace as needed.
g. Light deposits may be removed by wiping the
probe with a damp cloth. Wiping the probe
with a cloth soaked in vinegar will remove more
tenacious lime deposits. The most stubborn
deposits may be removed from the probe by
using a diluted amount (three 3 parts of water to
one (1) part) of phosphoric acid (H2PO4).
b. Reinstall burner mounting plate to front section
making sure 3/16” diameter rope gasket is in
place and forms gas tight seal. If gasket is
damaged, replace.
c. Bolt burner to burner mounting plate. Inspect
gasket to assure adequate seal. Replace if
damaged. Connect oil line(s) and/or gas line(s).
WARNING
d. Reinstall flue plates making sure gasket on each
plate is in place and forms gas tight seal. If
damaged, all edges of the cleanout plates should
be sealed with Silastic sealant when reinstalled
until insulation can be replaced.
Exercise caution when handling phosphoric acid
and follow the instructions on container label.
Always use protective clothing and equipment
when working with/near chemicals.
e. If removed, reinstall jacket top.
f. Reinstall left side panels.
g. Reinstall smokepipe.
h. Wire brushing of the probe is not recommended
as the soft platinum guard ring sandwiched
between the ceramic insulators may be damaged.
Care must be taken not to damage this ring in
any way or the useful life of the probe may be
shortened.
C. MAINTENANCE OF LOW WATER CUTOFF
DEVICES.
i. Clean the pipe threads of the probe to remove
old, hardened pipe dope and other foreign matter.
NOTICE
j. Apply a moderate amount of good quality pipe
dope to the pipe threads on the probe. Leaving
the two end threads bare. Do not use PTFE
(Teflon) tape.
Probe and float type low water cutoff devices
require annual inspection and maintenance.
1. PROBE TYPE LOW WATER CUTOFF
k. Screw the probe into the boiler tapping.
l. Mount the low water cutoff control on the probe.
m. Reconnect the control to probe wiring.
n. Fill the boiler to its normal waterline.
Although these devices are solid state in their
operation, the probe is exposed to possible
contamination in the boiler water and subject to
fouling.
It is important to physically remove the probe from
the boiler tapping annually and inspect that probe
for accumulation of scale or sediment.
o. Add boiler water treatment compound as needed.
p. Restore electric service to the boiler.
q. Fire burner to bring the water in the boiler to a
boil to drive off free oxygen.
Follow these steps to inspect, clean and/or replace
the probe:
r. BEFORE RETURNING BOILER TO
SERVICE Follow the low water cutoff checkout
procedure in Section IV, Paragraph E, Step 3.
a. Turn off electric service to the boiler.
b. Drain boiler water to a level below the tapping
for the probe.
2. FLOAT TYPE LOW WATER CUTOFF
During the heating season, if an external low water
cutoff is on the boiler, the blow off valve should
be opened once a month (use greater frequency
where conditions warrant), to flush out the sediment
chamber so the device will be free to function
properly.
DANGER
Assure that the boiler is at zero pressure before
removing the LWCO probe. Do not rely on the
pressure gauge to indicate that the boiler is at
zero pressure. Open the safety valve to relieve
all internal pressure prior to proceeding. Safety
valve discharge piping must be piped such that
the potential for burns is eliminated.
Low water cutoffs and water feeders should be
dismantled annually by qualified personnel, to the
extent necessary to insure freedom from obstructions
50
and proper functioning of the working parts. Inspect
connecting lines to boiler for accumulation of
mud, scale, etc., and clean as required. Examine
all visible wiring for brittle or worn insulation and
make sure electrical contacts are clean and that they
function properly. Give special attention to solder
joints on bellows and float when this type of control
is used. Check float for evidence of collapse and
check mercury bulb (where applicable) for mercury
separation or discoloration. DO NOT ATTEMPT
TO REPAIR MECHANISMS IN THE FIELD.
Complete replacement mechanisms, including
necessary gaskets and installation instructions, are
available from the manufacturer.
This will make less venting necessary during the
winter.
4. Where an expansion tank is used, make sure that
neither the tank nor its drain pipe is exposed to
freezing temperatures. Never place valves in piping
leading to or from expansion tank.
5. Boiler and system cleaning will help assure
trouble free operation. See Section IV - Operating
Instructions, Paragraphs F or G for procedure.
G. ATTENTION TO BOILER WHILE NOT IN
OPERATION
WARNING
D. CHECK BURNER AND CONTROLS at least
once a year. See Section IV - Operating Instructions,
Paragraph E for control checks. See Burner Manual for
burner tests and adjustments.
If boiler is not used during winter time, it must be
fully drained to prevent freeze damage.
1. Spray inside surfaces with light lubricating or
crankcase oil using gun with extended stem so as to
reach all corners.
E. LUBRICATE BOILER COMPONENTS according
to manufacturer’s instructions. Generally, this involves
the oil burner and circulator. This includes the type of
lubricant to use, frequency of lubrication, and points to
lubricate.
2. With steam boilers, at end of season add sufficient
water to fill boiler to top of water column and leave
it that way until fall when water should be drained
again to proper level. If at this time boiler water is
dirty, drain water, flush out boiler, and refill with
clean water to prescribed water level.
F. GENERAL MAINTENANCE CONSIDERATIONS
1. Keep radiators and convectors clean.
3. Always keep the manual fuel supply valve shut off
when the burner is shut down for an extended period
of time.
2. If a hot water radiator is hot at the bottom but not at
the top, it indicates that air has accumulated inside
and should be vented. To vent radiator, hold small
cup under air vent (located near top of radiator),
open vent until water escapes and then close.
4. To recondition the heating system in the fall season
after a prolonged shut down, follow the instructions
outlined in Section IV - Operating Instructions,
Paragraphs B through G.
3. If much water is added to system, it is advisable to
heat system to a high temperature and vent again.
