 WARNING: Any change to this heater or its controls 

can be dangerous.

 WARNING: Do not use a blower insert, heat ex-

changer insert or other accessory not approved for 

use with this heater.

 WARNING: Do not allow fans to blow directly into 

the fireplace. Avoid any drafts that alter burner flame 

patterns. Ceiling fans can create drafts that alter 

burner flame patterns. Altered burner patterns can 

cause sooting.

Due to high temperatures, the appliance should be 

located out of traffic and away from furniture and 

draperies.

Do not place clothing or other flammable material 

on or near the appliance. Never place any objects on 

the heater.

Heater base assembly becomes very hot when run-

ning heater. Keep children and adults away from hot 

surface to avoid burns or clothing ignition. Heater will 

remain hot for a time after shutdown. Allow surface 

to cool before touching.

Carefully supervise young children when they are in the 

room with heater. When using the hand-held remote 

accessory, keep selector switch in the OFF position to 

prevent children from turning on burners with remote.

You must operate this heater with a fireplace screen 

in place. Make sure fireplace screen is closed before 

running heater.

Keep the appliance area clear and free from combus-

tible materials, gasoline and other flammable vapors 

and liquids.

SAFETY  

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) inside 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 the fire department

4.  This heater shall not be installed in a bedroom or bathroom, un-

less installed as a vented appliance. See Installing Damper Clamp 

Accessory for Vented OperationPage 9. This gas log set may 

not be installed as a vented appliance in a bedroom or bathroom 

in the Commonwealth of Massachusetts.

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 fire-

place 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 MaintenancePage 20.

9.  Before using furniture polish, wax, carpet cleaner or similar prod-

ucts, 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 5. If heater 

keeps shutting off, see Troubleshooting, Page 22.

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. 

If optional remote control is used, make sure the selector switch is 

in the OFF position. Only a qualified service person should install, 

service or repair heater.
