Ventilation from Outdoors
If necessary, provide extra fresh air by using ventilation
grilles or ducts. Connect these items directly to the
outdoors or spaces open to the outdoors. These
include attics* and crawl spaces. Follow the National
Fuel Gas Code NFPA 54/ ANSI Z223.1, Section 5.3, Air
for Combustion and Ventilation for required size of
ventilation grilles or ducts.
*IMPORTANT: Do not provide openings for inlet or
outlet into attic. If attic has a thermostat-controlled
power vent, heated air entering the attic will activate
the power vent.
IMPORTANT: Vent-free heaters add moisture to the
air. Although this is beneficial, installing heater in
rooms without enough ventilation air may cause
mildew to form from too much moisture. See Fresh
Air for Combustion and Ventilation, pages 3 through
5.
INSTALLATION
NOTICE: This heater is intended for use as supplemental
heat. Use this heater along with your primary heating
system. Do not install this heater as your primary heat
source. If you have a central heating system, you may
run system’s circulating blower while using heater. This
will help circulate the heat throughout the house. In the
event of a power outage, you can use this heater as your
primary heat source for the duration of the outage.
WARNING: A qualified service person must install
heater. Follow all local codes.
CHECK GAS TYPE
Use only LP-gas. If your gas supply is not LP-gas, do
not install heater. Call dealer where you bought heater
for proper type heater.
THIS INSTALLATION REQUIRES:
Before installing heater, make sure you have the items
listed below:
• Piping (check local codes)
• Sealant (resistant to LP_Gas)
• Equipment shutoff valve*
• Ground joint union
• Test gauge connection*
• Sediment trap
• Tee joint
• Pipe wrench
*A CSA/AGA certified equipment shutoff valve with 1/8”
NPT tap is an acceptable alternative to test gauge
connection. Purchase a CSA/AGA certified equipment
shutoff valve from your dealer. See Accessories, page
17.
LOCATING HEATER
This heater is designed to be mounted on the wall. The
heater can also be located on a non-combustible floor,
away from a wall by using the floor mounting stands
included with the heater. If installed on combustible
flooring such as carpeting, tile or other combustible
material other than wood flooring, the heater must be
placed on a wood panel the full width and depth of the
appliance.
For convenience and efficiency, install the heater:
• Where there is easy access for operation,
inspection, and service.
• In the coldest part of the room.
• If planning to use fan, locate heater near an
electrical outlet.
CAUTION: If you install the heater in a home garage:
• Heater pilot and burner must be at least 18
inches above floor.
• Locate heater where moving vehicle will not hit it.
CAUTION:This heater creates warm air currents.
These currents move heat to wall surfaces next to heater.
Installing heater next to vinyl or cloth wall covering or
operating heater where impurities (such as tobacco smoke,
aromatic candles, cleaning fluids, oil or kerosene lamps,
etc.) are present in the air may discolor walls.
WARNING: Never install the heater:
• In a bathroom.
• In a bedroom (IR20LPT, IR30LPT, BF20LPT or
BF30LPT)
• In a recreational vehicle.
• Where curtains, furniture, clothing, or other
flammable objects are less than 36 inches from
the front, top, or sides of the heater.
• As a fireplace insert
• In high-traffic areas
• In windy or drafty areas
WARNING: Heater must be mounted to maintain the
minimum clearances shown in Figure 4. If possible,
provide greater clearances from the floor, ceiling, and
joining walls.
