important safetY information

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.  The installation must conform with local codes or, in 

the absence of local codes, with the National Fuel gas 
Code, ANSI Z223.l/NFPA 54. 

9.  this  unit  complies  with  Z21-91  Ventless  firebox 

enclosures for gas-fired unvented decorative room 
heaters. 

10.  Do not install the firebox in a bathroom or bedroom.
11.  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.

12. 

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. 

13.  Keep room area clear and free from combustible materi-

als, gasoline and other flammable vapors and liquids.

14.  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 2-3 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 period will be slight and will disappear with continued 
use.

 15. Always  have  a  fireplace  screen  in  place  when  the 

appliance is in operation and, unless other provisions 
for combustion air are provided, the screen shall have 
an opening(s) for induction of combustion air.
