5.  Before installing in a solid fuel burning fire

-

place, 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. Inspect chimney flue 

for damage. If damaged, repair flue before 

operating heater.

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

9.  To prevent the creation of soot, follow the 

instructions in 

Cleaning and Maintenance

page 23.

10.  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 or furniture.

11.  This heater needs fresh, outside air ventilation to 

run properly. This heater has an oxygen depletion 

sensing (ODS) pilot light safety system. The 

ODS shuts down the heater if not enough fresh 

air is available. See 

Air for Combustion and 

Ventilation

, page 6. If heater keeps shutting off, 

see

paper or other objects.

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. 

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

not operate heater if a log is chipped (dime-

sized or larger). 

16.  Turn heater off and let cool before servicing 

or repairing. If using optional remote control 

accessories, make sure the selector switch is in 

the OFF position. Only a qualified service per

-

son should install, service or repair heater.

17.  If using optional remote control accessories, 

make sure the selector switch is in the OFF 

position when you are away from home for 

long periods of time.

18.  This heater must not be connected to any 

external electrical source.

19.  To prevent performance problems, do not 

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

capacity (propane/LP units only).

20.  Operating heater above elevations of 4,500 

feet could cause pilot outage.
