CARE AND OPERATION

ALL MODELS

“BREAK-IN” PERIOD

The finish on this appliance is a high temperature paint that requires time and temperature to completely cure. The curing process will take 2 or 3 burns (heat up and cool down peri- ods). We recommend that you ventilate the house during the initial burns. The paint emits non-toxic odors during this proc- ess.

KEEP YOUR HOUSE WELL VENTILATED DURING THE CURING PROCESS TO PREVENT ACTIVATION OF YOUR HOME SMOKE DETECTOR.

Do not turn on a blower during the break-in process. Do not place anything on the stove surface until the paint is com- pletely cured. Do not attempt to repaint the stove until the paint is completely cured. If the surface later becomes stained or marred, it may be lightly sanded and touched up with spray paint (See Small Area Paint Touch-Up, page 20). Paint is avail- able at your local authorized Lennox Hearth Products dealer. Never attempt to paint a hot stove.

COMBUSTION CHAMBER RELIEF DOOR

This appliance is equipped with a relief door in case of delayed ignition blowback. If the relief door opens, remove back panel and inspect for gasket damage. If necessary, replace with fac- tory supplied gasket only. Confirm relief door is closed and properly seated, then replace back panel.

CIRCULATION BLOWER OPERATION

The speed of the circulation blower is controlled using the speed control rheostat (see following illustration) on the left hand side of the control panel. The blower system is designed with a variable speed control allowing an infinite range of blower settings to meet the customer’s needs. With the rotary switch turned fully CCW 4, the blower is off. Turning the switch CW 3 will activate the blower at its maximum speed. Further rotation of the switch in the CW direction will reduce the speed of the blower. At approximately 270° of CW 3 rota- tion, the switch provides a minimum setting for blower speed.

Thermostatic feature: With the control switch in any “ON” po- sition, the circulation blower is designed to automatically begin operation approximately 12 minutes after lighting the main burner. The blower will turn off approximately 15 minutes after the main burner is shut-off.
