Installation
PROVIDE ADEQUATE COMBUSTION
AND VENTILATION AIR
WARNING: If the area in which the heater may be operated is
smaller that that defined as an unconfined space or if the
building is of unusually tight construction, provide adequate
combustion and ventilation air by one of the methods
described in the National fuel Gas code, ANSI Z223.1 / NFPA
54, Section 5.3 or applicable local codes.
• This heater shall not be installed in a confined space or
unusually tight construction unless provisions are provided
for adequate combustion and ventilation air.
• This heater must have fresh air for proper operation. If not,
poor fuel combustion could result. Read the following
instructions to insure proper fresh air for this and other fuel
burning appliances in your home.
GAS TYPE
Verify the type of gas supply to be used, either natural gas or
LP (Propane), and make sure the marking on the appliance
rating plate agrees with that of the supply gas. The rating plate
is located on the side of the heater, which indicates the type of
gas the heater is manufactured for.
Modern construction standards have resulted in homes that
are highly energy efficient and that allow little heat loss.
However, your home needs to breathe and all fuel burning
appliances need fresh air to function properly and safely.
Exhaust fans, clothes dryer, fireplaces and other fuel burning
appliances all use the air inside the building. If the available
fresh air supply is insufficient to meet the demands of these
appliances, problems can result.
WARNING: This appliance is only for use with the type of gas
indicated on the rating plate.
This appliance is not convertible for use with other gases.
Confined Space:
The National fuel Gas Code, ANSI Z223.1 / NFPA 54 defines a
confined space as a space whose volume is less than 50
cubic feet per 1000 BTU per hour (4.8 m3 per kw) of the
aggregate input rating of all appliances installed in that space.
ITEMS NEEDED FOR
HEATER INSTALLATION
Before installing the heater, make sure you have these items:
• Gas piping (check local codes)
• Test gauge connection
• Sealant (resistant to LP gases) - approved thread
compound
• Manual shut-off valve*
• Sediment trap - where required
• Ground joint union
Unconfined Space:
An unconfined space is defined in the same standards as a
space whose volume is not less than 50 cubic feet per 1000
BTU per hour (4.8 m3 per kw) of the aggregate input rating of
all appliances installed in that space. Rooms communicating
directly with the space in which the appliances are installed,
through openings not furnished with doors, are considered a
part of the unconfined space.
• Tee joint and pipe wrench
*An installer supplied design-certified manual shut-off valve
with 1/8 NPT tap connection.
Example:
10,000 BTU Legacy heater should only be installed in a room
whose volume is more than 500 cubic feet. A room that is 8'
x 8' x 8' (512 cubic feet) would be acceptable for a Legacy
10,000 BTU/hour heater.
If an additional fuel fired appliance is installed in the same
room, the input rating of that appliance should be added to
that of the Legacy heater to determine the minimum sized
room that should be serviced by both appliances.
Unusually tight construction is defined as construction
where:
a) Walls and ceilings exposed to the outside atmosphere have a
continuous water vapour retarder with a rating of 1 perm (6 x
10-11 kg per pa-sec-m2) or less with openings gasketed or
sealed;
b) Weather stripping has been added on openable windows and
doors; and
c) Caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates and
floors, between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical and gas lines and at
other openings.

CONNECT TO GAS SUPPLY
PRESSURE TEST GAS SUPPLY
PIPING SYSTEM
Installation should be done by a qualified service person.
Before connecting the appliance, turn off all gas appliances.
Close the main gas valve at the gas meter or LP tank. Make
certain there is good ventilation where the installation will be
made. Installation should comply with all applicable building
codes and ANSI Z223.1, latest edition. Use PLP gas resistant
pipe compound to seal threaded joints.
The appliance and its individual shut off (control) valve must
be disconnected from the gas supply piping system during any
pressure testing of the system at test pressure in excess of
1/2 psi (3.5 kPa).
The appliance must be isolated from the gas supply piping
system by closing the individual manual shut-off valve (fig. 7)
during any pressure testing of the gas supply system at test
pressure equal to or less than 1/2 psi (3.5 kPa).
An installer supplied, design certified gas pressure
regulator must be installed to bring the gas supply pressure
down to 14" w.c. for LP gas or 11" for natural gas.
WARNING: Never connect an unregulated gas line to the
heater.
IMPORTANT: Check gas line pressure before connecting heater
to gas line. Gas line pressure must not be higher higher than
14" w.c. for LP gas or 11" for natural gas.
NOTE: The gas line connection can be made with 3/8”black or
steel pipe. Internally tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of large enough
diameter to allow proper gas volume to heater. If pipe is too
small, undue pressure loss will occur.
CAUTION: Use pipe joint sealant that is resistant to liquefied
petroleum gases. Install sediment trap in supply as shown in
Figure 6.
Locate sediment trap where it is within reach for cleaning.
Locate sediment trap where matter is not likely to freeze. A
sediment trap prevents moisture and contaminant's from going
into the heater controls. If the sediment trap is not installed or is
installed wrong, the heater may not operate properly.
Test for gas leaks with a mild soap and water solution. Apply
water/soap solution with brush only - do not over apply.
NEVER test with an open flame.
Fig. 7 Manual shut-off valve location.
LEAK TESTING HEATER
GAS CONNECTION

Clean the exterior with soft bristle brush, vacuum cleaner or
pressurized air. Never use a wooden toothpick as it may break
off and clog the ODS pilot or main burner port.
compartments, burners and circulating air passageways of the
heater be kept clean. Dust, lint, cobwebs or debris may affect
heater performance. The heater draws air into it during normal
operation and in the process dust, lint or debris may be drawn
in also. It is important to keep the burner, gas control and
combustion and circulating air passageways clean. Inspect or
have these areas inspected annually at the beginning of the
heating season by a qualified service person. Depending on
the surroundings, the room heater may require frequent clean-
ing due to excessive lint or debris.
Use a flashlight to inspect the main burner inlet to ensure it is
not blocked. If obstruction can be seen, use a metal wire coat
hanger that has been straightened out. Use a vacuum cleaner
to clean the primary air openings to the main burner(s).
WARNING: Failure to keep the primary air openings to the
burner(s) clean may result in sooting and property dam-
age.
In order to clean ODS pilot orifice, use pressurized air to blow
dust out. Sometimes blowing air backwards through the pilot
will get rid of the accumulated dirt. If that does not work blow
out any dust through primary air openings of pilot assemblies
(This unit has two openings; one beneath the bimetal strip and
the second one opposite from bimetal strip. Use the one wide
open, do not try to lift the bimetal strip.)
Before cleaning ensure the gas supply is off and the gas con-
trol knob is in the OFF position. Make sure the heater is cool.
WARNING: Danger of bodily injury. If fan assembly accesso-
ry is used, turn off power supply at disconnect switch or
service panel before removing any access panels from
heater.
CLEANING AIR PASSAGEWAYS AND
UNIT CASINGS
Use a vacuum cleaner or pressurized air to clean the combus-
tion and circulating air passageways and dampened cloth to
clean the cabinet/casing.
