Maintenance
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.
