Care and Maintenance

Maintenance

All maintenance and service are to be performed by a qualified service technician, preferably one who has attended Rinnai service training classes on the Direct Vent products.

The appliance should be inspected annually by a qualified service technician. More frequent cleaning may be required due to excessive lint from carpeting, bedding material, etc. It is imperative that control compartments, burners, and circulating air passage ways of the appliance be kept clean.

Any screen or guard removed for servicing the appliance must be replaced prior to operating the appliance. Clean as follows:

1.Turn heat off. Allow to cool for one hour.

2.Remove the front panel by removing two screws.

3.Use pressurized air to remove dust from the main burner, heat exchanger, and fan blades.

4.Use soft dry cloth to wipe cabinet.

Do not use wet cloth or spray cleaners on the burner.

The flue should be inspected annually for blockages or damage.

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

Verify proper operation after servicing.

Care of Exterior

Dampen soft cloth with warm water. Wring water out well and wipe the unit.

Do not use volatile substances such as benzene or thinners. They cause fading of the paint and deformation of the resin.

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 by obstructions.

Refer to the Flue Terminal Clearances. The clearance in Ref. A should be maintained from any snow accumulation.

Filters

Dirty filters reduce the air flow and the appliance’s ability to produce heat. The filters should be cleaned frequently during the heating season. If the filters become blocked the filter indicator lamp will flash and the appliance will beep. Eventually the appliance will turn off and the Temperature Level lamp 14 will light, indicating a fault code.

To clean the filters, the

and cool. Remove the

completely.

 

Visual Inspection

Check that the burner flames are operating normally. The flame can be seen through the circular window through the louvers.

When operating normally the burner flame should appear as long, clear, blue, stable, streaks. Yellow flames or an orange color is abnormal and maintenance is required.
