death from fire, burns, explosion or carbon monoxide poisoning.
• Do not allow fans to blow directly into the stove. Avoid any drafts that
alter burner flame patterns.
• Do not use a blower insert, heat exchanger insert or other accessory, not
approved for use with this heater where applicable.
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 and 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 passageways 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.l/NFPA54.
10. This unit complies with the latest edition of ANSI
Z21.11.2, Unvented Heaters.
11. Do not install heater in a bathroom or bedroom unless
approved for bedroom use.
12. Correct installation of the ceramic fiber 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.
58D6002
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. 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. Provisions for adequate combustion and ventilation air must
be provided. Refer to Page 7.

OPERATING INSTRUCTIONS
Unvented Cast Iron Gas Stoves
OPERATING INSTRUCTIONS
Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the stove.
Do not place a blower inside the burn area of the stove. Ceiling fans may create drafts that alter
flame patterns. Sooting and improper burning will result.
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 will be slight and will disappear with continued use.
