13 Owner’s information
The furnace must be inspected and started ANNUALLY, at the
beginning of the heating season, only by a qualified service technician.
The service technician must perform annual service and maintenance on the furnace to ensure reliable operation.
Failure to service and maintain the furnace and system could result in equipment failure, causing severe personal
injury, death or substantial property damage.
As the owner, you nee to be aware of the following requirements: You must inspect and clean or replace the
furnace filter monthly, as described below, and perform the other inspection procedures as well. Failure to maintain
a clean filter will result in cycling of the furnace and could lead to a no-heat condition. Failure to perform this
maintenance could result in substantial property damage.
Follow all of the procedures below. Failure to comply could result in severe personal injury, death or substantial
property damage.
Operating the furnace
1. The furnace should operate automatically on call for heat from the room thermostat.
2. If the furnace oil burner should shut down on flame failure, the burner primary control will lock out. Ask your
service technician to show you the correct procedure to reset the primary control button. NEVER push the
button more than once in an attempt to start the burner after lockout. Continued lockout of the control means
something is wrong with the burner, controls or oil system. The condition must be corrected by a qualified
service technician.
