Filter replacement:
To ensure an adequate replacement filter is selected, should the filter require replacing, refer to Table 4,
in
Air Filters
section of this manual, for the minimum filter areas required for different types of available
filters.
NOTICE: Remind the homeowner of the importance of monthly filter inspections
during operation to ensure maximum operating efficiency.
G. EXTENDED APPLIANCE SHUTDOWN:
Should the appliance be shutdown or turned off for an extended period of time, several steps can be
taken to help insure a smooth and reliable restart of the heating system.
ON SHUTDOWN:
1. Close oil supply (or manual shutoff) valve.
2. Disconnect all electrical power to the unit.
3. Fill the oil tank to reduce water condensation in the tank.
4. If the shutdown period will exceed one heating season, an oil stabilizer should be added to the oil
tank. Consult your oil supplier for recommendations.
: Do not attempt to start burner when:
•
Primary reset has been engaged more than two times.
•
Excess oil has accumulated in the combustion chamber or beneath
the burner assembly.
•
The combustion chamber or the heat exchanger is full of fuel vapor.
•
The combustion chamber is very hot.
