• As a general guide, the regular maintenance items such as
the igniter, fuel filters (internal and external), and air filter
(internal) should be replaced as opposed to inspected and
cleaned. Their performance may be deteriorating and/or
their remaining service life ending without any apparent
visual signs or operating symptoms.
• The major components such as the air compressor, fuel
pump, fuel nozzle, and combustion air fan should be
examined for wear and should be replaced by the service
technician as required.
• The combustion tube should be inspected by the service
technician for wear and replaced if necessary. To access
the combustion tube, the front panel of the POLAR™HD
must be removed along with the burner box cover. The
fuel block must then be removed from its mounting
position. Finally, the burner and counter-flow tube must
be taken out by removing the nuts holding the burner box
in position. If the tube is satisfactory, a thorough cleaning
of the tube and burner chamber should be performed by
blowing out and vacuuming any ash and carbon buildup.
Any build up on the surface of the burner chamber will
cause the heater to lose efficiency.
• Regular inspection and maintenance is the only way to
ensure safe, reliable and efficient operation of your heating
system.
