WARNING
Any appliance that burns natural gas, propane gas, fuel oil, or coal is capable of
producing carbon monoxide (CO). Carbon Monoxide (CO) is a gas which is
odorless, colorless and tasteless but is very toxic. CO is lighter than air and thus
may travel throughout the building.
BRIEF EXPOSURE TO HIGH CONCENTRATIONS OF CO, OR
PROLONGED EXPOSURE TO LESSER AMOUNTS OF CO MAY
RESULT IN CARBON MONOXIDE POISONING. EXPOSURE CAN
BE FATAL AND EXPOSURE TO HIGH CONCENTRATIONS MAY
RESULT IN THE SUDDEN ONSET OF SYMPTOMS INCLUDING
UNCONSCIOUSNESS.
Symptoms of CO poisoning include the following:
dizziness
headache
nausea
vision problems
loss of muscle control
weakness
shortness of breath
unclear thinking
unconsciousness
The symptoms of CO poisoning are often confused with those of influenza, and the
highest incidence of poisoning occurs at the onset of cold weather or during flu
season. A victim may not experience any symptoms, only one symptom, or a few
symptoms. Suspect the presence of carbon monoxide if symptoms tend to
disappear when you leave your home.
The following signs may indicate the presence of carbon monoxide:
•
Hot gasses from appliance, venting
system pipes or chimney, escaping into
the living space.
•
•
Stale or smelly air.
The presence of soot or carbon in or
around the appliance.
•
•
Flames coming out around the appli-
ance.
Yellow colored flames in the appliance.
•
Very high unexplained humidity inside
the building.
IF ANY OF THE SYMPTOMS OCCUR, OR IF ANY OF THE SIGNS OF CARBON
MONOXIDE ARE PRESENT, VACATE THE PREMISES IMMEDIATELY AND
CONTACT A QUALIFIED HEATING SERVICE COMPANY, THE GAS COMPANY
OR THE FIRE DEPARTMENT.
ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM
WORK ON YOUR B-10 BOILER.

2. Boiler Block Assembly
All QHT BIASI B10 Series Boilers are shipped from the factory in assembled
boiler blocks. If, however, the block needs to be split into sections for ease of
delivery, please read the following:
To assemble split blocks, move sections into parallel and facing each other.
Sections may be slid along boards placed underneath the sections. Inspect nipple
ports for damage or burrs. Remove any burrs by scraping the port very lightly. Wipe
the push nipples and nipple ports with a clean cloth. Apply a film of nipple compound
to both the nipple and port. Install the nipple in the port and then seal by hitting with
a hammer cushioned with a block of wood. Apply section sealant to one section only
and slide sections together. Install the four draw rods and draw the sections together
evenly (measure with yardstick). Draw the sections together until sections make
iron-to-iron contact at a point around the top and bottom ports of each section.
DO NOT OVER TIGHTEN DRAW RODS
NOTE: When cutting off excess length of draw rods, allow enough length to install
boiler jacket on the draw rods.

4. Installation of Boiler Trim Components Cont.
1. Install L4006A aquastat in upper left or right rear tapping using 3/4” immersion
well. All tapings and joints should be sealed with piping compound. The L4006A
can be adjusted up to 220o F, and should be set to the desired temperature by
the installer. The differential is also adjustable between 5 and 30 degrees. It
should be set as close to 30 degrees as possible to prevent short cycling of the
boiler. If you are installing a 7248U, Screw the unit to side panel of the boiler as
close to the immersion well as possible using the tabs on the aquastat. Run the
sensor from behind the aquastat to the immersion well and fix it according to
Honeywell’s instructions. The 7248 can be adjusted between 140o F and 220o F
with a fixed differential of 30 degrees.
2. Install Pressure Relief Valve in opposite, upper rear tapping using 3” nipple and
3/4” elbow
3. Install 3/4” boiler drain in lower left or right rear tapping, or lower front tapping.
4. install 3/4” plug in opposite lower rear tapping, and/or the other plug in lower front
tapping of the boiler.
5. Install combination pressure/temperature gauge and 1/2” x 1/4” bushing in upper
front tapping. The gauge must be tightened using a wrench and not your
hand.
6. Install burner mounting hardware in the four tapings on the front of the boiler
door.
7. Install boiler door bolts on opposite side of door hinge.

5. Piping the Boiler
All piping must conform to state and local codes. Page 11 shows the location
and size of the boiler tappings. It is recommended to install unions and gate valves
at the inlet and outlet of the boiler, so it may be readily isolated for service.
For Canadian installations, a low water cut off is required if the boiler is
installed above the level of radiation. Even if the boiler is installed below the level of
radiation it is strongly recommended that a low water cut off be installed. Install
manual and/or automatic air venting devices at the high points in the system to
eliminate trapped air. The weight of all piping should be supported by suitable
hangars and floor stands, not by the boiler’s purging/expansion station. Clearance
for hot water pipes are 1 inch to combustibles. The make-up water line must be
piped into the boiler and be fitted with a backflow preventer and a pressure-
reducing valve to reduce line pressure to 10 to 15 psi.
In the case of a gas installation, the boiler should be installed such that the
gas ignition system components are protected from water (dripping, spraying, etc.)
during appliance operation and service (circulator replacement, condensate trap,
control replacement, etc.).
If the boiler is to be used in conjunction with a chilled water system, it must be
piped with the appropriate valves to ensure the chilled medium does not enter the
boiler. If the boiler is connected to heating coils in an air handling system, where the
coils could be exposed to cold air circulation, provisions for freeze protection control
must be installed. The boiler must have flow control valves or other automatic
means to prevent gravity circulation of the boiler water during the cooling cycle.
NOTE: If the heating system is to be filled with antifreeze, use only formulations expressly made for
hydronic heating systems (such as propylene glycol). Do not use automotive types of antifreeze
(ethylene glycol). Use of antifreeze will alter system output and characteristics. Consult a factory
representative for details or assistance.
SAFETY RELIEF VALVE
1. The safety relief valve should be piped into one of the two upper tapings in the
rear of the boiler
2. The relief valve should be installed using the hardware supplied in the trim kit
without valving between the PRV and the boiler.
3. Pipe the discharge for the safety relief valve with copper tube to within four
inches from the floor to prevent injury in the event or a pressure release. Provide
piping that is the same size as the safety relief valve outlet.

6. Intake Venting
1. Be certain adequate air is available for combustion and ventilation.
a.) Boiler located in unconfined space:
Installation in large areas, such as basements, can usually be assumed to
provide sufficient air.
b.) Boiler located in confined space : (See Figure A.)
If all air for combustion and ventilation is to come from within the building:
Two (2) openings shall be provided with one (1) opening commencing within
12 inches of the ceiling and one (1) opening commencing within 12 inches of
the floor of the enclosure. These openings shall not be located closer than 3
inches from either the top or bottom of the enclosure and shall be open to
areas connecting freely with the outdoors. The area of each opening shall
not be less than one square inch per 1000 BTU/HR. of total input rating of all
appliances within the enclosure; with a minimum of 100 square inches for
each opening.
If all the air for combustion and ventilation is to come from outside the
building: Two (2) openings shall be provided with one opening commencing
within 12 inches of the top and an opening commencing within 12 inches of
the bottom of the enclosure. These openings shall not be located closer than
3 inches from either the top or bottom of the enclosure, and shall connect
directly or by ducts with the outdoors. The area of each opening shall be
equal to one square inch per 4000 BTU/HR of total input rating. If ducts are
used to convey the air, vertical ducts require areas of one square inch per
4000 BTU/hr. Horizontal ducts require one square inch per 2000 BTU/hr.
Ducts shall have the same cross sectional area as the full area of the louver
openings.
The upper opening is essential for maintenance of proper air
circulation with the boiler and of reasonable ambient temperature to maintain
proper control temperatures. When a duct is used for ventilation, check for
louver free net area and correct for screen resistance to ensure that the
sufficient ventilation area has been satisfied. DO NOT INSTALL THE
BOILER UNTIL PROPER COMBUSTION AIR HAS BEEN ARRANGED.

6. Intake Venting Cont.
c.) Boiler located in a room under negative pressure:
If the boiler is to be installed within a home where the operation of exhaust
fans, attic fans, kitchen ventilation systems, clothes dryers or fireplaces may
create severe negative vent pressures causing unsatisfactory combustion and
venting, special provisions should be made for additional make-up air to
supply the other air requirements. If building is of tight construction,
combustion air requirements may not be met and combustion air ducts from
outside may be necessary. Please refer to NFPA No. 31.
Tight Construction (as defined by ANSI Z223.1):
1. Walls and ceilings exposed to the outside atmosphere have a
continuous water vapor retarder with a rating of 1 perm or less with
openings sealed with gaskets, etc..
2. Weather-stripping has been added on open able windows and doors,
and caulking or sealants are applied to areas such as: joints around
windows and door frames, between sole plates and floors, between wall-
ceiling joints, between wall panels, at penetrations for plumbing,
electrical, and gas lines, and in other openings.
If the building is of tight construction, air openings must be provided from the
outside, with appropriate sizing depending on amount of BTU/H as shown in
pictures. The boiler room must never be under a negative pressure, even if
the appliance is installed as direct vent. Always provide air openings sized
not only to the dimensions required for the firing rate of all appliances, but
also to handle the air movement rate of the exhaust fans or air movers using
air from the building or boiler room.
Figure A.

7. Exhaust Venting
The B10 boiler is a high efficiency unit that requires proper venting. The boiler must
be vented to the outdoors by means of a tile lined masonry or a approved pre-fabricated
chimney of the size and height recommended by the manufacturer or by a listed "power
venting" unit which provides draft by mechanical means. In many installations, particularly
older interior and most exterior chimneys, a corrosion resistant liner should be installed and
may be required by code. Please consult liner manufacturer for the appropriate chimney
liner.
The chimney discharge opening must be located at least 24 inches above any part of
the building structure within 4 feet of the chimney. Be sure the chimney and smoke pipe
won't become obstructed by squirrels, bird nests, soot buildup, chimney liner deterioration,
etc.. If using a "power venter" system, it is suggested that it should be installed on the
leeward side of the house. (Please consult with manufacturer of "power venter" for
requirements concerning clearances from combustibles and distances from doors and
windows.) The "venter" must be installed by a licensed burner mechanic and done in
accordance with local codes. This is a very low stack temperature boiler (350F gross temp.)
so caution should be used when connecting to an outside built chimney. Should you have
concern that the flue gases could condense, then you should consider lining the chimney or
using a listed, "power venting" or " direct venting unit". If "power venting" is used to
discharge flue gases, then the power vent unit should be equipped with a postpurge control
such as a delay-off, timing control to prevent problems with fogging and nozzle post drip.
The exhaust pipe connection from the boiler to the chimney should be as short as
possible, with a minimum number of elbows. The vent pipe must have a vertical rise of at
least 1/4 inch per foot of horizontal run. The vent pipe must be of the same diameter as the
flue outlet on the boiler. The chimney connector should have a minimum thickness of 26
gauge, corrosion resistant (galvanized) steel, and be assembled with a minimum of three (3)
sheet-metal screws in each joint. In some one and two story houses, a barometric draft
control isn't required as the B-10 is designed to be pressure-fired. However in high draft
situations which exceed the flue gas resistance through the boiler, a barometric draft control
is recommended. The over fire draft should be positive and between 0 and .06 inches of
water column. The draft at the breech should be enough to overcome the resistance
through the boiler.
7.1 Common Exhaust Venting Cont.
Common vent exhaust:
If this boiler is replacing one that was part of a common venting system, it is
likely that the vent is to large to vent the appliances still attached to it. To prevent this,
at the time of removal, the following steps shall be followed with each appliance re-
maining connected to the common venting system. Place each appliance in opera-
tion, while the other appliances remaining connected to the common venting system
are not in operation.
1.Seal any unused openings in the common venting system.
2.Visually inspect the venting system for proper size and horizontal pitch and deter-
mine there is no blockage or restriction, leakage, corrosion and other deficiencies
which could cause an unsafe condition.

7.1 Common Exhaust Venting Cont.
3.Insofar as practical, close all building doors and windows and all doors between
the space in which the appliance remaining connected to the common venting
system is located and other spaces of the building . Turn on any appliance not
connected to the common vent system. Turn on all exhaust fans except for
summer exhaust fans. Close the fireplace damper if applicable.
4.Place in operation the appliance being inspected. Follow the lighting instructions.
Adjust thermostat so appliance will operate continuously.
5.Test for spillage at the barometric damper opening after 5 minutes of main burner
operation. Use the flame of a match or candle, or smoke from a cigarette, cigar or
pipe.
6.After it has been determined that each appliance remaining connected to the
common venting system properly vents when tested as outlined above, return the
doors, windows, exhaust fans, fireplace dampers and any other gas-burning
appliance to their previous condition of use.
7.Any improper operation of the common venting system should be corrected so
the installation conforms with the National fuel Gas Code, ANSI Z223.1 and/or
CAN/CGA B149, Installation Codes. When resizing any portion of the common
venting system, the common venting system should be resized to approach the
minimum size as determined using the appropriate tables in Part 11 of the
National Fuel Gas Code, ANSI Z223.1, and/or CAN/CGA B149, Installation
Codes.
7.2 Blocked Flue Switch:
1. Pierce a 5/8” hole into the vent pipe near the appliance outlet. Remove one of the securing
nuts from the pipe of the safety switch. Tighten the other securing nut onto the pipe as far
as possible.
2. Insert the threaded pipe end into the pierced hole, then install the securing nut, then install
the securing nut, which was removed in step 1, and tighten securely.
3. Please consult the wiring section of this manual for the wiring of the blocked flue switch.

7.3 Gas Venting
For boilers connected to gas vents or chimneys, vent installations shall be in
accordance with part 7, Venting of Equipment, of the National Fuel Gas Code, ANSI
Z223.1 or Section 7, Venting Systems and Air Supply for Appliances, of the CAN/
CGA B149, Installation Codes, or applicable provisions of the local building codes.
Vent connectors serving appliances vented by natural draft shall not be
connected into any portion of mechanical draft systems operating under positive
pressure.

8. Burner Setup
Good, reliable operation with a minimum of service, starts with attention to the small
details:
Oil:
1. Setting the nozzle position and electrodes "by the book" using the
manufacturer's gauges.
2. Installing a quality micron filter at the burner.
3. Making careful/tight flare connections, without couplings, on oil suction
line.
4. Checking fuel pump pressure.
5. Checking draft at the breeching to insure it is adequate to overcome flue
gas resistance. (-.02 to –.04 in. w.c.)
6. Setting the air band properly with well maintained instruments. A good
target is 11% to 12.5% of (CO2) or 6.5% to 3.8% of (O2).
To ensure proper burner setup, gauges should be used to check things such as the
pump pressure, CO2 levels, etc…
Gas:
1. Checking the electrode, orifice size, and flame rod settings against
manufacturer’s specs to insure proper operation.
2. Installing properly sized gas piping according to BTU input required and
length of gas line run.
3. Making sure there is proper manifold pressure before and after the
gas valve using a calibrated manometer.
4. Checking draft at the breeching to insure it is adequate to overcome flue
gas resistance. (-.02 to –.04 in. w.c.)
5. Setting the air band properly with well maintained instruments. A good
target is 9.5% to 10.5% of (CO2) or 5% to 2.5% of (O2) for natural gas, or
10.0% to 12.0% of (CO2) or 5% to 2.5% of (O2) for LP gas.

9. Gas Line Piping
Gas supply piping is to be sized and installed properly in order to provide a
supply of gas sufficient to meet the maximum demand without undue loss of
pressure between the meter and the boiler. Consult with the National Fuel Gas
Code ANSI Z223.1 for proper sizing of gas piping for various lengths and diameters.
Locate a drop pipe adjacent to, but not in front of the boiler. Locate a tee in the
drop pipe at the same elevation as the gas inlet connection to the boiler. Extend the
drop line with a nipple towards the floor and cap to form a sediment trap. Install a
shut off valve before the tee with sediment trap and a union after the tee before the
combination gas valve.
When installing the boiler, make sure a pipe compound resistant to the action of
liquefied petroleum is used. Check piping for leaks. Always check leaks with a water
and soap solution. DO NOT USE A FLAME FOR CHECKING GAS LEAKS
The boiler and its individual shut-off valve must be disconnected from the gas
supply piping during any pressure testing of that piping at test pressures in excess of
1/2 psi.

To check for gas
leaks, use a gas detec-

10. Boiler Jacket Assembly
NOTE: All piping, boiler controls, gauges and valves should be installed before the
jacket is assembled on the boiler. Below is an explosion view of the boiler and
jacket assembly to clarify these boiler jacket assembly instructions. Insert the
separate (loose) piece of insulation on top of boiler with the foil side facing in so the
entire top, bottom and sides of boiler are covered. Place tubular jacket spacers (#35
& #36 on exploded view of boiler) on the upper and lower draw rod extensions at the
front(long spacers) and rear(short spacers) of the boiler. Place the rear insulated
jacket panel (#26) at the back of the boiler, also by slipping over the slotted cut-outs.
Position side jacket panels (#38 & #25) by slipping the slotted cut-outs over the
boiler draw rods. Place the lower front jacket panel (#28) in place and secure with
self-tapping screws provided. Fasten the washers and hex nuts to the ends of the
tie-rods to hold the jacket in place. Set the top panel (#27) in place and secure with
two screws in the back of the panel. With the jacket firmly secured, place front panel
(#37) in position on the tabs on the side panels and press firmly to snap spring
connectors in place.
NOTE: Do not attach any electrical wiring or electrical conduit or boiler piping to the
top panel (#27).
Note: For replacement parts, contact your local Biasi Wholesaler.

11. Wiring
The electricity to the boiler shall come from a dedicated breaker in the electric
service box. A service switch should be mounted on the side of the boiler so the
burner technician can service the burner and controls. The electrical wiring should
be routed so as not to interfere with normal servicing of the boiler. Wiring done in the
field between devices not attached to boiler shall conform with the temperature
limitations for type T wire (63F/35C) or other specified wire as applicable when
installed in accordance to manufacturer's instructions and wiring diagrams.
If an external electrical source is utilized, the boiler, when installed, must be
electrically bonded to ground in accordance with the requirements of the authority
having jurisdiction or, in the absence of such requirements, with the National
Electrical Code, ANSI/NFPA 70 and/or the Canadian Electrical Code Part 1, CSA
C22.1, Electrical Code.
Since the boiler is equipped with a swinging burner door, the supplied 48”
long burner wiring harness with 4-prong quick disconnect plug needs to be used.
The short end of the wiring harness needs to be wired to the burner following the
respective burner wiring diagram in the subsequent pages of this manual. The long
end of the wiring harness needs to be wired into the burner service switch located at
the installers discretion.
Refer to pages 19 to 23 for oil wiring diagrams and pages 24 to 25 for gas wiring
diagrams.

11. Wiring
7248U WIRING PROCEDURE
If you received a Honeywell 7248U with your Biasi boiler, you will need to make the changes
shown above, and described below to the wiring diagrams.
1. Run wire 1 to the L1 terminal on the 7248U instead of running wire 1 to the 4006A.
2. Run wire 2 to the L2 terminal on the 7248U instead of connecting to wire 4.
3. Run wire 4 to the B2 terminal on the 7248U instead of connecting to wire 2.
4. Run wire 5 to the B1 terminal on the 7248U instead of connecting to the isolated end
switch.
5. Lastly, run low voltage wiring from the TT terminals on the 7248U to the isolated end
switch.

12. Commissioning
Before a gas boiler may be put into operation and tested, it’s gas connection
must be leak tested. After installation of oil/gas-fired boiler, operation and
performance tests shall be conducted to make certain that the burner is operating in
an acceptable manner and that all safety controls and devices function properly. It is
critical that the high limit, low water cutoff and burner "cad cell" relay be checked for
normal operation before leaving the job.
CAUTION
Label all wires prior to disconnection when servicing controls. Wiring errors can
cause improper and dangerous operation.
13. Maintenance
The Biasi boiler system should be serviced once a year.
1. Inspect the boiler and make sure it is operating normally, i.e. temperature and
pressure.
2. Inspect the Pressure Relief Valve and manually set it off three times to ensure it
is operating normally and not leaking.
3. If a Low Water Cut-Off is installed follow the manufactures suggested
maintenance and test procedures.
4. Adjust room thermostat so there is a call for heat and test boiler high limit for
proper operation.
5. Turn boiler safety switch off.
6. Open lower swing door and remove upper clean out plate.
7. Brush upper passages first and then clean combustion chamber of any debris
with brush and vacuum.
8. Remove smoke pipe and clean out debris from cleaning or soot build up.
9. Inspect smoke pipe for any corrosion before reinstalling. Replace if necessary.
10.Consult the burner manufacturers manual for annual maintenance of the burner.
11.Remove all combustible materials from around boiler and ensure the area is free
of debris so the burner has adequate intake air supply.
Notice
Verify proper operation after servicing.
