For safe operation of the appliance it is imperative that 
the control compartment (pilot cover), burner and 
circulating air passageways are kept clean.  To keep the 
gas orifices from getting clogged, ensure that debris is 
kept clear from the fire, and that the burn media is 
installed correctly. 
The appliance should be inspected before use and at 
least annually by a qualified service technician.  More 
frequent cleaning may be required.   
Regular servicing is not covered by Rinnai’s warranty. 
All parts of the heater can be cleaned using a soft damp 
cloth and mild detergent.  Do not use solvents and do 
not attempt to clean the appliance while it is hot or 
operating. 
For salty environments, clean regularly using water to 
prevent corrosion. 
For black soot on stones or exhaust gas staining above 
the appliance, clean with water. 
Verify proper operation after servicing. 
Visual Inspection of Flame 
The Rinnai outdoor fireplace has a distinct flame 
pattern.  This should look the same every time after 
an initial warm up period of approximately 30 minutes. 
Abnormal flame pattern can indicate a problem with 
your appliance.  Blocked gas orifices or burn media 
that have shifted can produce an abnormal flame 
pattern.  There are some warning signs that could 
indicate a problem. 
•  Unusual smell from the appliance. 
•  Continued difficulty or delay in establishing a 
flame. 
•  Flame appears either very short or very long. 
•  Flame only burns part way across the burner. 
•  Soot building up on the inside of the glass door.

Outdoor fires are not fully weatherproof and should not
