Flame Color and Behavior
Your stove is designed for maximum heating efficiency.
Therefore, upon lighting of the main burner the flames will
be semitransparent or “bluish.” After 10-20 minutes of
operation, the logs will heat up and the flames will become
a yellow/orange color.
Adjusting the stove to cause the flames to turn orange sooner
may result in poor combustion, sooting and a hazardous
situation. See the drawing to the right showing proper flame
appearance.
When testing for proper operation - If an optional thermo-
stat is installed adjust it to its highest temperature setting.
Visually determine that main burner gas is burning properly:
i.e., no floating, lifting or flashback. Adjust the primary air
shutter(s) as required. Check for proper main burner opera-
tion at both high and low flame.
8. After pilot is lit, turn gas control counter-clockwise to
“ON.” Knob can only be turned “ON” if the knob has popped
out.
9. To turn burner on, turn “ON/OFF” rocker switch to “ON” or
set the thermostat to the desired temperature above room
temperature.
10. Adjust the flame height (and heat output) by turning the flame
height knob clockwise for reduced flame and counter-
clockwise for full flame.
11. Set the blower to the desired air flow after it turns on when the
appliance reaches operating temperature.
TO TURN OFF GAS TO APPLIANCE
1. Turn the “ON/OFF” rocker switch and/or thermostat (if installed)
to “OFF.”
2. Turn off electric power to the appliance if service is to be
performed.
3. Turn gas control knob clockwise to “OFF.” Do not
force.
This appliance needs fresh air for safe operation and must be
installed so there are provisions for adequate combustion and
ventilation air. See Installation and Operation Manual accompa-
nying appliance.
SHUTDOWN PROCEDURE
To turn off the burner, turn the rocker switch to “OFF” or adjust
the thermostat (if installed) to a setting below room temperature.
The pilot will remain lit for future burner ignition. For complete
shutdown, see “TO TURN OFF GAS TO APPLIANCE” above.

WARNINGS
• Improper installation, adjustment, alteration,
service or maintenance can cause injury or
property damage. For assistance or additional
information, consult a qualified installer, service
agency or your gas supplier.
• Operation of this appliance when not connected
to a properly installed and maintained venting
system can result in carbon monoxide (CO)
poisoning and possible death.
• Carbon monoxide poisoning – early signs of
carbon monoxide poisoning resemble the flu
with headaches, dizziness, or nausea. If you
have these signs, get fresh air at once! Have
the heater inspected by a qualified service
technician. Some people are more affected by
carbon monoxide than others. These include
pregnant women, people with heart or lung
disease or anemia, those under the influence
of alcohol and those at high altitudes.
