• 

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 firebox 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 firebox.

4.  Do not place clothing or other flammable material 

near the fireplace when the firebox is in use.

5.  Any safety screen or guard removed for servicing, 

must be replaced prior to operating a heater within 

the firebox. 

6.  Installation and repair should be done by a qualified 

service person.

7.   To prevent malfunction and/or sooting, an unvented 

gas heater/firebox should be cleaned at least annu-

ally by a professional service person. More frequent 

cleaning may be required due to excessive lint from 

carpeting, etc. It is imperative that control compart-

ments, 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 Z21.91 ventless firebox 

enclosures  for  gas-fired  unvented  decorative  room 

heaters.

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.

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. See log place-

ment 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 appli-

ances will not filter or clean soot produced by these 

types of products. In addition, the smoke and/or aro-

matics (scents) may be reburnt in the vent-free appli-

ance which can produce odors. It is recommended to 

minimize the use of candles, incense, etc. while the 

vent-free appliance is in operation. 

16. 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. 

17. Keep  room  area  clear  and  free  from  combustible 

materials, gasoline and other flammable vapors and 

liquids.

18. Unvented gas heaters are a supplemental zone heater. 

They are not intended to be a primary heating appli-

ance.

19. 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. 

20. 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.
