Burner Flame Adjustment
Service Reminder
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 rheostat (provided with the deluxe blower) field-mounted remotely or on the appliance panel. The blower speed selected 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 appliance vent termination for any obstructions. If any are
found, remove them.
Contact your Lennox dealer for a periodic inspection by a
qualified service technician.
Call your Lennox service technician if unit is inoperative.
Before calling, always check the following to be sure service 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 replacement parts.
To ensure the safe operation of your Lennox gas appliance and to keep it in peak operating condition year after year, contact your independent Lennox dealer about a
planned service program.
