INSTALLER
• 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.
• 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

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 materials,
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 ANSI Z21.11.2 Unvented
Heaters, latest edition.
11. Do not install the unvented heater in a bathroom.
12. Do not install the unvented heater in a bedroom unless
the maximum input rating is equal to or less than
10,000 Btu/hr.
71D0533
13. 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. Refer to log
placement instructions for proper installation.
14. 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.
15. Caution: Candles, incense, oil lamps, etc. produce
combustion byproducts 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.
16. 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.
17. This heater shall not be installed in a room or space
unless the required volume of indoor combustion air is
provided by the method described in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, the International
Fuel Gas Code or applicable local codes.
18. Keep room area clear and free from combustible
materials, gasoline and other flammable vapors and
liquids.
19. Unvented gas heaters are a supplemental zone heater.
They are not intended to be the primary heating appliance.
20. 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.

OUTSIDE COMBUSTION AIR
VFH Series Vent Free Fireplace
Combustion Air
1. Locate combustion air assembly at an exterior location which is not likely to be accidentally blocked
in any manner. Locate assembly a min. of 12" above the snow line to prevent blockage by snow
accumulation.
2. Never mount the combustion air inlet assembly in a garage or storage area where combustible fumes
such as gasoline might be drawn into the fireplace.
3. Combustion air can be drawn from the crawl space under a house when an adequate supply of air
is provided by open ventilation.
4. CAUTION: Do not take combustion air from attic space or garage space.
5. Locate air supply inlet at least 3' away from any appliance vent terminal.
6. Avoid extremely long runs and numerous turns in the duct leading from the fireplace to the combustion air assembly. These conditions increase the resistance to the free flow of air through the duct.
Refer to Figures 33 through 36 for methods of installing the outside air for combustion assemblies.
