Required Care and Maintenance
Care and Maintenance
All maintenance and service is 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 three 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.
When attaching the front panel, take care not to clip or
pinch any electric cords to prevent electric shock.
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.
CAUTION
Prevent dust from accumulating on the power cord,
side covers, and parts behind the appliance.
CAUTION
Keep the area around flue terminal free of snow and
ice. The appliance will not function properly if the in-
take 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
appliance should be OFF
and cool. Remove the
filter and clean it using a
soft dry cloth or vacuum.
If the filter is greasy
wash with warm soapy
water, rinse, and dry
completely.
Do not use the appliance
without the filters installed.
Visual Inspection of Flame
Check that the burner flames are operating normally.
The flame can be seen through the circular window.
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.
