1.  This appliance is only for use with the type of 

gas indicated on the rating plate. This appliance 

is not convertible for use with other gases. 

2.  Do not place propane/LP supply tank(s) in-

side any structure. Locate propane/LP supply 

tank(s) outdoors (propane/LP units only).

3.  If you smell gas

•  shut off gas supply

•  do not try to light any appliance

•  do not touch any electrical switch; do not 

use any phone in your building

•  immediately call your gas supplier from 

a  neighborʼs  phone.  Follow  the  gas 

supplierʼs instructions

•  if you cannot reach your gas supplier, call 

the fire department

4.  This heater shall not be installed in a bedroom or 

bathroom, unless installed as a vented appliance. 

See 

Installing Damper Clamp Accessory for 

Vented Operation

, page 12 (Remote-Ready and 

Variable Manually-Controlled Models Only).

5.  Before  installing  in  a  solid  fuel  burning 

fireplace, the chimney flue and firebox must 

be cleaned of soot, creosote, ashes and loose 

paint by a qualified chimney cleaner. Creosote 

will ignite if highly heated. A dirty chimney 

flue  may  create  and  distribute  soot  within 

the house. Inspect chimney flue for damage. 

If damaged, repair  flue and firebox before 

operating heater.

6.  Do not burn solid-fuel in a masonry or UL127 

factory-built fireplace in which a vent-free 

room heater is installed.

7.  If fireplace has glass doors, never operate this 

heater with glass doors closed. If you operate 

heater with doors closed, heat buildup inside 

fireplace will cause glass to burst. Make sure 

there are no obstructions across openings of 

fireplace. 

8.  To prevent the creation of soot, follow the 

instructions in 

Cleaning and Maintenance

page 27.

9.  Before  using  furniture  polish,  wax,  carpet 

cleaner, or similar products, turn heater off. 

If heated, the vapors from these products may 

create a white powder residue within burner 

box or on adjacent walls and furniture.

SAFETY INFORMATION

Continued

10.  This heater needs fresh, outside air ventilation to 

run properly. This heater has an Oxygen Deple-

tion Sensing (ODS) safety shutoff system. The 

ODS shuts down the heater if enough fresh air 

is not available. See 

Air for Combustion and 

Ventilation

, page 6. If heater keeps shutting off, 

see

any gas control which has been under water.

position when you are away from home for long 

periods of time (Remote-Ready Models Only). 

17.  Remote-Ready heaters do not to be connected 

to any external electrical source.

18.  Operating heater above elevations of 4,500 

feet may cause pilot outage.

19.  To  prevent  performance  problems,  do  not 

use propane/LP fuel tank of less than 100 lb.
