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 red 
and a beep will sound five time.  
This beeping will repeat every 5 
minutes.  Eventually the 
appliance will turn off and display 
fault code 14 on the control 
panel display. 
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 filter installed. 
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 five 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. 
Visual Inspection of Flame 
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. 
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 (page 18).  
The clearance in Ref. A should be maintained from 
any snow accumulation.
