IMPORTANT SAFETY INFORMATION
Continued from page 3
14. Caution: Candles, incense, oil lamps, etc. produce
combustion by-products including soot. Vent-free
appliances will not filter or clean soot produced by
these types of products. In addition, the smoke
and/or aromatics (scents) may be reburnt in the
vent-free appliance which can produce odors. It
is recommended to minimize the use of candles,
incense, etc. while the vent-free appliance is in
operation.
15. This is an unvented gas-fired heater. It uses air
(oxygen) from the room in which it is installed. Pro-
visions for adequate combustion and ventilation air
must be provided. See page 8.
16. Keep room area clear and free from combustible
materials, gasoline and other flammable vapors
and liquids.
17. Unvented gas heaters are a supplemental zone
heater. They are not intended to be a primary heat-
ing appliance.
18. Unvented gas heaters emit moisture into the living
area. In most homes of average construction, this
does not pose a problem. In houses of extremely
tight construction, addition mechanical ventilation
is recommended.
19. During manufacturing, fabricating and shipping,
various components of this appliance are treated
with certain oils, films or bonding agents. These
chemicals are not harmful but may produce annoy-
ing smoke and smells as they are burned off during
the initial operation of the appliance; possibly caus-
ing headaches or eye or lung irritation. This is a
normal and temporary occurrence.
The initial break-in operation should last two to three
hours with the burner at the highest setting. Provide
maximum ventilation by opening windows or doors
to allow odors to dissipate. Any odors remaining
after this initial break-in period will be slight and will
disappear with continued use.
20. Input ratings are shown in BTU per hour and are for
elevations up to 2,000 feet. For elevations above
2,000 feet, input ratings should be reduced 4 per-
cent for each 1,000 feet above sea level. Refer to
the National Fuel Gas Code.
21. The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5 kPa).
22. The appliance must be isolated from the gas supply
piping system by closing its equipment shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2
psig (3.5 kPa).
23. Do not use this room heater if any part has been
under water. Immediately call a qualified service
technician to inspect the room heater and to replace
any part of the control system and any gas control
which has been under water.
24. Never burn solid fuels in an unvented room heater,
fireplace or stove.
25. Do not set kettles or humidifying devices on top of
stove.
26. The stove door/screen must be closed when the
appliance is operating. The screen shall have open-
ings for induction of combustion air.
