Deterioration of Front Grill
Sunpak heater must be installed in such a manner
as to allow the products of combustion or hot
gases to vent out the top of the heater. When
operating normally, only radiant heat passes
through the front grill. If conditions exist which force
hot gases through the front grill of the heater, the
installation must be altered to correct the condition.
Rumbling Burner Noise
Rumbling burner noise, flare out of burner, and
losses of radiant heat are all symptoms of a
damaged infrared burner. These symptoms may
occur any time after the heater has warmed up.
Under these conditions the burner has been
damaged and must be replaced. Discontinue use
of the heater until heater is repaired.
