TROUBLESHOOTING
Replace nozzle with correct size for
operating altitude or adjust and
tune burners for operating altitude
PROBLEM POSSIBLE CAUSE SOLUTION
Incorrect nozzle size for
operating altitude or burners
have not been adjusted for
operating altitude.
Faulty or fouled nozzle will
hamper the efficient burn of
the oil and may cause an
accumulation of excess fuel in
the bottom of the heat
exchanger cavity. The oil
residue will continue to burn
after the heater shuts down
and soot will then “burn back”
into the controls area.
Replace the nozzle
Electrodes out of alignment.
The electrode holder has an
adjustment screw that is used
to center the electrode in the
center of the cone. Should the
screw loosen and the
electrode be off center, the oil,
when firing, may strike the side
of the blast tube and then
accumulate in the bottom of
the heater resulting in a “burn
back” condition.
Check the alignment of the electrodes in the
end cone and adjust as necessary
Improper setting of the air
band assembly. The air band
assembly should be set with
approximately ¾ of the slot
area open; an opening less
than that may cause a sooty
burn as a result of choking off
the required combustion air.
The band is set at the factory;
however it may loosen in
shipment or on the jobsite
Check the air band adjustment and tighten
the retaining screw
The heater smokes
when firing and/or there
is a rapid build-up of
soot in the chamber
and on the flame
detector. As a result
the heater may
prematurely lock out or
in the worst case have a
fire in the combustion
chamber.
Use of No. 2 Diesel fuel Use up remaining No. 2 diesel or blend with
No. 1 diesel. Clean cad cell flame detector
before putting back into service.
