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 or furniture.

10. This heater needs fresh, outside air ven

-

tilation to run properly. This heater has an 
Oxygen Depletion Sensing (ODS) safety 
shutoff 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 

Troubleshooting,

 page 25.

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 ex-

posed 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 servic-

ing, installing or repairing. Make sure the 

selector switch is in the OFF position. 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.

17. Remote-ready  heaters  do  not  need  to 

be  connected  to  any  external  electrical 
source.

18. Operating  heater  above  elevations  of 

4,500 feet could cause pilot outage.

19. To  prevent  performance  problems  with 

propane/LP models, do not use propane/

LP fuel tank of less than 100 lb. capacity.

20. Provide adequate clearances around air 

openings.

Keep  the  appliance  area  clear 

and free from combustible ma

-

terials, gasoline and other flam

-

mable vapors and liquids.

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 sup-
plier’s instructions

• if  you  cannot  reach  your  gas  supplier, 

call the fire department

4.  This heater shall not be installed in a bed-

room or bathroom unless installed as a 
vented appliance. See 

Installing Damper 

Clamp Accessory for Vented Operation,

 

page  13.  This  gas  log  set  may  not  be 
installed as a vented appliance in a bed-
room or bathroom in the Commonwealth 
of Massachusetts.

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. A dirty 

chimney  flue  may  create  and  distribute 

soot  within  the  house.  Inspect  chimney 

flue and firebox for damage. If damaged, 
repair flue 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.
