Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You
must provide two permanent openings: one within 12 inches
of the ceiling and one within 12 inches of the floor. Connect
these items directly to the outdoors or spaces open to the
outdoors. These spaces include attics and crawl spaces.
Follow the National Fuel Gas Code, ANSI Z223.1/ NFPA 54,
Air for Combustion and Ventilation for required size of
ventilation grills or ducts.
IMPORTANT:
Do not provide openings for inlet or
outlet air into attic if attic has a thermostat-controlled
power vent. Heated air entering the attic will activate the power vent. Rework worksheet, adding the
space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all
appliances in both spaces.
7. 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.
Caution:
If you install the heater in a home garage, heater pilot and burner must be
at least
18 inches above the floor.
Place heater where moving vehicle will not hit it.
WARNING:
A qualified service person must install heater. Follow all local codes.
WARNING:
Never install the heater:
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
in high traffic areas
in windy or drafty areas
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 coverings or operating heater where impurities (such
as tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may
cause walls to discolor.
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 too much moisture. See Air for
Combustion and Ventilation.
