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 Z21.91.2001 ventless fire-

box enclosures for gas-fired unvented decorative room 
heaters.

11.  Do not install heater in a bathroom or bedroom.
12.   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.  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 
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. 

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.

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  apli-
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.

• Do not use a blower insert, heat exchanger insert or other accessory, not approved 

for use with this heater where applicable.
