SAFETy INFORMATION

Continued

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 

neighbor’s phone. Follow the gas supplier’s 

instructions

• if you cannot reach your gas supplier, call

or bathroom, unless installed as a vented appli

-

ance. See 

Installing Damper Clamp Accessory 

for Vented Operation

, page 12 (Remote-Ready 

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 26.

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.

10.  This heater needs fresh, outside air ventilation 

to run properly. This heater has an Oxygen 

Depletion 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 

Troubleshooting

, page 28.

11.  Do not run heater

• where flammable liquids or vapors are used 

or stored

• under dusty conditions

12.  Do not use this heater to cook food or burn 

paper or other objects.

13.  Do not use heater if any part has been exposed 

to or under water. Immediately call a qualified 

service technician to inspect the room heater 

and to replace any part of the control system 

and any gas control which has been under 

water. 

14.  Do not operate heater if any log is broken. Do 

not operate heater if a log is chipped (dime-

sized or larger). 

15.  Turn heater off and let cool before servicing, 

installing or repairing. Make sure the selector 

switch is in the OFF position (Remote-Ready 

Models Only). Only a qualified service person 

should install, service or repair heater.

16.  Make sure the selector switch is in the OFF 

position when you are away from home for 

long periods of time (Remote-Ready Models 

Only). 

17.  Remote-ready heaters must not 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. 

capacity (propane/LP units only).

20.  Provide  adequate  clearances  around  air 

openings.

 CAUTION: Do not remove the 

data plates from the grate assembly. 

The data plates contain important
