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, unless installed as 
a vented appliance. See 

Installing Damper 

Clamp  Accessory  for  Vented  Operation

page  11.  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 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 opening of fireplace.

8.  To prevent the creation of soot, follow the 

instructions in 

Cleaning and Maintenance

page 22.

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 venti-

lation 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 24.

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. Only a qualified 
service person should install, service, or 
repair heater.

16. Operating  heater  above  elevations  of 

4,500 feet may cause pilot outage.

17. To prevent performance problems, do not 

use propane/LP fuel tank of less than 100 
lb. capacity (propane/LP units only).

18. Provide adequate clearances around air 

openings.
