Should airflow be restricted, the furnace might cycle on and off too frequently or become
inoperative. The fan timer board will indicate this limit activation sequence by the
flashing of the red LED. When this LED is flashing the call for heat is disrupted and the
blower will run continuously until the limit has been satisfied. Then the LED will stop
flashing. To correct this condition, verify that all supply and return dampers and
registers in the air distribution system are open. If this fails to resolve the problem, turn
off the electrical power to the furnace. Remove the blower compartment access door to
examine the air filter(s) and blower for blockages or a loose blower wheel. (On the
highboy and horizontal / counterflow furnaces, air filters should be mounted external to
the furnace casing.) If possible, correct the condition by cleaning or replacing the air
filter(s), freeing the blower wheel of any foreign materials, or securing the blower wheel
to the fan motor shaft. Always replace the blower compartment access door when
service is finished. Restore electrical power to the furnace.
Room Thermostat
Most room thermostats are equipped with user adjustable, or selectable, levels of heat
anticipation. This feature helps to reduce the amount of room air temperature overshoot
that occurs after a heating cycle.
To adjust the heat anticipator, measure the electrical current output of the oil burner
primary safety control to the room thermostat. (If measurement is not possible, the value
of current output may be marked on the cover of the control). Set the thermostat heat
anticipator to match the electrical current output of the oil primary safety control.
Instructions to Our Customer / End User
! WARNING: If the burner does not operate properly after depressing the oil
primary reset button three (3) times, turn off the electrical power to the furnace
and close the manual oil shutoff valve. Immediately contact a qualified heating
contractor for service.
Before leaving a new installation, the installer should show the customer or end user
where the furnace instruction manual is kept. He should also discuss the following
points:
1) Describe the general operation of the furnace and, if properly equipped, the
cooling system.
2) Show the location of the furnace air filter(s) and those in the duct system, if
equipped. Demonstrate how to remove, clean, and replace the air filter(s).
3) Demonstrate how to set and adjust the room air temperature using the room
thermostat.
