•

Improper installation or use of the heater can cause serious injury or death from fire, burns,

explosion or carbon monoxide poisoning.

INSTALLER

Please leave these instructions with the appliance.

OWNER

Please retain these instructions for future reference

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. To prevent malfunction and/or soot

ing, an unvented fireplace 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 mate

rials, etc. It is imperative that control compartments,

burners and circulating air passageways be kept

clean.

7. WARNING: Any change to this heater or its controls

can be dangerous.

8. Unvented fireplaces are a supplemental zone

heater. They are not intended to be the primary

heating appliance.

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.

10. The installation must conform with local codes or, in

the absence of local codes, with the

National Fuel

Gas Code, ANSI Z223.l/NFPA54.

11. This unit complies with ANSI Z21.11.2:19

Unvented

Heaters

12. Do not install the heaters in a bathroom or bedroom.
13. Correct installation of the ceramic fiber logs, proper

location of the heater, and annual cleaning are neces

sary 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 reburned 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 fireplace. It uses air (oxygen) from

the room in which it is installed. Provisions for adequate

combustion and ventilation air must be provided. Refer

Page 8.

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 mate

rials, gasoline and other flammable vapors and liquids.

19. Unvented fireplaces emit moisture into the living area.

In most homes of average construction, this does not

pose a problem. In houses of extremely tight con

struction, additional mechanical ventilation is recom

mended.

20. During manufacturing, fabricating and shipping, various

components of this appliance are treated with certain

oils, films or bonding agents. These chemicals are not
