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 Z21.91 ventless firebox 

enclosures for gas-fired unvented decorative room heat

-

ers.

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. 

Caution:

  Candles,  incense,  oil  lamps,  etc.  produce 

combustion byproducts including soot. Vent-free appli-

ances 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.  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. 

OWNER

Please retain these instructions for future reference.

IMPORTANT

Read these instructions carefully before installing or trying to operate a vent-free gas heater in this firebox. 

IMPORTANT SAFETY INFORMATION

  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 appli-

ance. 

  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 exces

-

sive 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.

Continued on page 4

• 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.
