5.Use soft dry cloth to wipe cabinet.

Vent System (V53i)

The vent system should be inspected at least annually for blockages or damage.

Air Intake and Exhaust (V53e)

The air intake and exhaust should be inspected at least annually for blockages or damage.

Motors

Motors are permanently lubricated and do not need periodic lubrication. Keep fan and motor free of dust and dirt by cleaning annually.

Temperature Controller

Use a soft damp cloth to clean the temperature controller. Do not use solvents.

Lime / Scale Build-up

If you receive Error Code “LC”, refer to the procedure, Flushing the Heat Exchanger. Refer to the section on Water Quality to see if your water needs to be treated or conditioned. (When checking maintenance code history, “00” is substituted for “LC”.)

Snow Accumulation

Keep the area around flue terminal free of snow and ice. The appliance will not function properly if the intake air or exhaust is impeded (blocked or partially blocked) by obstructions.
