Clean as follows:

1.Turn off and disconnect electrical power. Allow to cool.

2.Remove and clean the water inlet filter.

3.Remove the front panel by removing 4 screws.

4.Use pressurized air to remove dust from the main burner, heat exchanger, and fan blades. Do not use a wet cloth or spray cleaners on the burner. Do not use volatile substances such as benzene and thinners. They may ignite or fade the paint.

5.Use soft dry cloth to wipe cabinet.

Air Intake and Exhaust

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.

Remote Controller

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

Lime/Scale Buildup

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.

Visual Inspection of Flame

The burner must flame evenly over the entire surface when operating correctly. The flame must burn with a clear, blue, stable flame. See the parts breakdown of the burner for the location of the view ports.
