PLACING FIREPLACE INTO OPERATION
1 – Turn ON the burner switch (if applicable), or set the
thermostat to the desired setting (if applicable).
Millivolt models only, and in applications without
optional appliance-mounted or optional wall-
mounted ON/OFF switch or optional thermostat
– Press gas valve knob partially and turn counter-
clockwise
to ON.
2 – Optional standard blower , if installed, will energize
immediately. Burner will ignite in approximately three
to five seconds.
Optional deluxe blower , if installed, will self-energize
when a comfortable minimum temperature has been
reached.
NOTE – Immediately after burner ignites, condensate may
temporarily fog glass. This is normal. Fog will clear as soon
as temperatures within the fire box rise. If droplets continue
to form after 15 minutes of operation on a high-flame set-
ting, contact a qualified service technician.
NOTE – During the initial operation of the appliance, a
white film my form on the inside of the glass. This is normal.
If this occurs, clean the glass after the first 5 hours of use.
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 should be cleaned by a ser-
vice technician, if necessary.
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.
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.
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 (if appli-
cable) 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.
To ensure the safe operation of your Lennox gas ap-
pliance and to keep it in peak operating condition year af-
ter year, contact your independent Lennox dealer about a
planned service program.
