SAFETY
Continued
12. This heater needs fresh, outside air ven
-
tilation 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
Troubleshooting
, page 24.

• where flammable liquids or vapors are
used or stored
• under dusty conditions

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.
16. Do not operate heater if any log is broken.
Do not operate heater if a log is chipped
(dime-sized or larger).

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.
18. Make sure the selector switch is in the
OFF position when you are away from
home for long periods of time.
19. This heater must not be connected to any
external electrical source.
20. Operating heater above elevations of
4,500 feet could cause pilot outage.
21. Provide adequate clearances around air
openings.

clean.
23. Solid fuels shall not be burned in a fire
-
place in which an unvented room heater
is installed.
4. 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

call the fire department
5. 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.
6. 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.
7. Do not burn solid-fuel in a masonry or
UL127 factory-built fireplace in which a
vent-free room heater is installed.
8. 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.
9. This log heater is designed to be smoke-
less. If logs ever appear to smoke, turn off
heater and call a qualified service person.
Note:
During initial operation, slight smok
-
ing could occur due to log curing and
heater burning manufacturing residues.
10. To prevent the creation of soot, follow the
instructions in
Cleaning and Maintenance,
page 23.
11. Before using furniture polish, wax, carpet
cleaner, or similar products, turn heater
off. If heated, the vapors from these prod
-
ucts may create a white powder residue
within burner box or on adjacent walls or
furniture.
