COMMON CAUSES OF TROUBLE
CAUTION
To avoid accidents, always open main switch (OFF position) when servicing the burner.
BURNER WILL NOT PRODUCE FLAME
Check oil level gauge to see that there is sufficient oil in tank or tanks. Check the burner mounted relay control. Do not adjust this control.
Check position of electrodes – incorrect position will cause slow or delayed ignition. Clean electrodes and nozzle. Check and clean strainer in pump. If oil line filter is used, check filter condition.
If burner runs but there is no flame the fuel pump may be air bound. Follow instructions for bleeding fuel pump.
Check and make sure the solenoid valve on the oil pump is being energized and opening.
BURNER STARTS OR STOPS TOO OFTEN
Check heat anticipator setting on thermostat.
NOZZLE PRODUCES A STRINGY FLAME
Worn tangential grooves in nozzle. Replace nozzle.
BASEMENT TANK HUM
Occasionally with a
HEAVY FIRE OR PULSATING FLAME.
These may occur after burner starts. It may be caused by a slight oil leak in the fuel pump and cannot be corrected except by replacing the pump. This happens only when the burner is started.
CHATTERING SOUND OR HIGH PITCH NOISE
This noise from motor can usually be traced to where a conduit or BX cable is fixed rigidly or attached to some part of the building. Relieving this strain may eliminate noise.
PUMP SQUEALS OR CHATTERS
This may be caused by air in pipes. Check all joints in the oil supply pipe for leaks. Check strainer in pump; if dirty, clean.
INSUFFICIENT HEAT
Check limit control setting. It may be that flame is not allowed to stay on long enough to generate sufficient heat in furnace to heat the house properly. If the proper size furnace has been selected according to house requirements and satisfactory heat is not obtained, recheck the heating plant for size and capacity in relation to house. Check for clogged filters.
Check and make sure the heat anticipator on the thermostat is set correctly.
CARE OF FINISH
This furnace cabinet is made with a very durable and corrosion resistant finish. With normal cleaning it will last for many years.
WARNING
Under no circumstance should a soot deterioration device be used in the combustion chamber. These products known as “soot busters” or “soot sticks” are comprised of chemicals that burn at very high temperatures which may exceed the temperature rating of the combustion chamber material.
Use of these products are detrimental to the life expectancy of the combustion chamber and will destroy the chamber. Refer to the “Cleaning of Furnace” section for proper cleaning methods.
CLEANING OF THE HEAT EXCHANGER
All of these units have four clean out plugs for easy cleaning of the heat exchanger. They are accessible from the front and back of these units by removing the clean out access cover in the burner compartment and at the back of unit. The furnace should be checked annually by a qualified service technician.
