Servicing Fan Convector
There's very little service required on the Fan Convector heaters. Below you will find three items that
can be checked and/or cleaned in the event you are experiencing problems with you appliance.
NOTE; ALL Service must be performed by a qualified installer, service agency or gas technician.
1. Gas control valve – The gas valve can be checked by verifying the manifold gas pressures are properly set. The
manifold gas pressure setting procedures can be found in the technical data sheet under the unit's front cover.
2. Burner Assembly – The burners are ceramic type burners and should never fail if the unit is not over fired
for any reason, dropped or abused. I would recommend that the burner compartment be blown out with
compressed air (120 psi) at least annually. This will clear out any foreign matter that has been drawn into the
combustion chamber. Low pressure blowers do not generate enough air pressure to properly clean the burner. See
the parts breakdown in the Owner's manual for directions on how to remove the burner's top plate in order to
access the burner.
3. Annual Cleaning – Rinnai recommends that you blow out all compartments inside the unit. In addition, blow out
the squirrel cage fan. Care should be taken when blowing out the fan. Keep the air nozzle at least twelve inches
away from the fan when blowing it out. Otherwise, high pressure air will cause damage to the fan blades.
