Safety Information

IMPORTANT
Read these instructions carefully before installing or trying to
operate a vent-free gas heater in this firebox.
1. Due to high temperatures, the appliance should be located out of
traffic and away from furniture and draperies.
2. Children and adults should be alerted to the hazard of high
surface temperature and should stay away to avoid burns or
clothing ignition.
3. Young children should be carefully supervised when they are in
the same room with the appliance.
4. Do not place clothing or other flammable material on or near
the appliance.
5. Any safety screen or guard removed for servicing an appliance
must be replaced prior to operating the heater.
6. Installation and repair should be done by a qualified
service person.
7. To prevent malfunction and/or sooting, an unvented gas heater
should be cleaned before use at least annually by a
professional service person. More frequent cleaning may be
required due to excessive lint from carpeting, bedding material,
etc. It is imperative that control compartments, burners and
circulating air passages be kept clean.
8. CARBON MONOXIDE POISONING: Early signs of carbon
monoxide poisoning are similar to the flu with headaches,
dizziness and/or nausea. If you have these signs, obtain fresh
air immediately. Have the heater serviced as it may not be
operating properly.
9. The installation must conform with local codes or, in the absence
of local codes, with the National Fuel Gas Code, ANSI
Z223.1/NFPA54.
10. This unit complies with ANSI Z21.91.2001 ventless firebox
enclosures for gas-fired unvented decorative room heaters.
11. Do not install heater in a bathroom or bedroom.
12. Correct installation of the logs, proper location of the heater, and
annual cleaning are necessary to avoid potential problems with
sooting. Sooting, resulting from improper installation or
operation, can settle on surfaces outside the fireplace. See log
placement instructions for proper installation.
13. Avoid any drafts that alter burner flame patterns. Do not allow
fans to blow directly into fireplace. Do not place a blower inside
burn area of firebox. Ceiling fans may create drafts that alter
burner flame patterns. Sooting and improper burning will occur.
14. Candles, incense oil lamps, etc. produce
combustion byproducts including soot. Vent-free appliances will
not filter or clean soot produced 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. An unvented gas-fired heater uses air (oxygen) from the room in
which it is installed. Provisions for adequate combustion and
ventilation air must be provided. See installation guidelines.
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 heating 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, additional 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 annoying smoke and smells as they are burned off
during the initial operation of the appliance, possibly causing
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 continual 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% 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 systems during any
pressure testing of that system at test pressures in excess of
1/2 psig (3.5kPa).
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 a fireplace where an unvented room
heater is installed.
25. Always have a fireplace screen in place when the appliance is in
operation, and unless other provisions for combustion air are
provided, the screen shall have an opening(s) for induction of
combustion air.
26. Do not fill spaces around the firebox with insulation or other
materials. These spaces must be maintained to prevent the
firebox from coming in contact with combustible materials.
• Any change to this heater or its
controls can be dangerous.
• Improper installation or use of the heater can
cause serious injury or death from fire, burns,
explosion or carbon monoxide poisoning.
• Do NOT allow fans to blow directly into the
fireplace. Avoid any drafts that alter burner
flame patterns.
