WARNING
If you do not follow these instructions exactly, a fire
or explosion may result causing property damage,
personal injury or loss of life.

use tools. If the knob will not turn by hand, do not try to repair
it, call a qualified service technician. Force or attempted re-
pair may result in a fire or explosion.

Burner Flame Adjustment
The burner flame on this appliance may be adjusted at the
gas valve to obtain the desired heating output. Burner
flame color varies with the different log sets and burners
available. In most cases the flame will be blue at start-up
and turn yellow after 5 to 10 minutes of operation. The
burner flame should be inspected at the beginning of each
heating season and burner tube should be cleaned by a
service technician, if necessary.
Blower Operation (Deluxe models)
The optional deluxe blower may be controlled by a rheo-
stat (provided with the deluxe blower) field-mounted re-
motely or on the appliance panel. The blower speed se-
lected should approximate the heat output adjustment at
the gas valve. A high blower speed matched with a low
heat output can lead to condensation.
Vent Termination Inspection
Annually (before the heating season) inspect the ap-
pliance vent termination for any obstructions. If any are
found, remove them.
Contact your Lennox dealer for a periodic inspection by a
qualified service technician.
Service Reminder
Call your Lennox service technician if unit is inoperative.
Before calling, always check the following to be sure ser-
vice is required.
1 - Check ON/OFF appliance-mounted switch or wall-
mounted switch (if applicable) to make sure it is in ON
position.
2 - Check room thermostat, if applicable, for proper set-
ting.
3 - Is pilot lit?
4 - Is gas valve in ON position (millivolt units)?
5 - Is gas turned ON at meter?
6 - Is manual main shut-off valve open?
7 - Is electrical power turned ON to the appliance (if ap-
plicable)?
Contact your local independent Lennox dealer for re-
placement parts.
