V. DEALER MAINTENANCE:

SAFETY DURING SERVICING AND INSPECTION

: Personal injury or property damage could result from repair or service of this appliance by anyone other than a qualified heating contractor. The user may only perform the activities described in the Homeowner/User Routine Maintenance section of this manual.

: To avoid injury from moving parts, or electrical shock, shut off the power to the appliance before removing blower compartment door and servicing this appliance.

: When servicing controls, label all wires prior to disconnecting. Reconnect any removed wires correctly. Wiring errors can cause improper and dangerous operation. Dangerous operation can result in injury or damage.

IMPORTANT: Verify the proper operation of this appliance after any servicing is performed.

A qualified heating contractor should perform the following maintenance procedures at the beginning of each heating season. Correct any deficiencies at once.

A.GENERAL INSPECTION:

WARNING: Shut off oil and disconnect power before continuing with this inspection.

1.Vent terminal - Visually inspect the terminal for restrictions, loose or missing fasteners, external damage, and carbon build-up. Clean the vent terminal and the screen(s) covering any opening in the terminal. Repair any minor damage. If necessary, replace a severely damaged or degraded vent terminal.

2.Burner – Visually check the burner, and below the burner, for indications of oil leaks. Correct any, if found. Remove the burner and measure the ignition electrode gap. It should be set to 5/32 inch. Adjust it, if necessary. Clean any accumulation of dust, dirt, or debris from the air shutter or air band openings. If necessary, clean housing and blower wheel with a damp cloth. Use a vacuum to remove any lint or dust from motor assembly. Add a few drops of non-detergent oil to each of the motor lubrication holes.

3.Combustion Chamber - Inspect the liner for deterioration, oil and carbon build-up. If the accumulation of oil or carbon is significant, this is a strong indicator that the burner is out of adjustment. Inspect the burner nozzle for partial blockage and excessive wear. Replace it, if required. Check and adjust oil pump pressure, if needed. Refer to Initial Heating System Adjustments section of this manual.

Note: Care must be given to ensure no damage occurs to the chamber insert. (Refer to Figure 12)

4.Heat Exchanger – Visually inspect the heat exchanger for excessive carbon (soot) build-up. Refer to the Heat Exchanger section of the manual.

5.Oil Filter – Replace the supply line oil filter cartridge with a new filter of the same type and rating. Clean the body of, or mounting plate for, the oil filter.

6.Labels and Markings - Clean all appliance labels, markings, and instruction plates, as necessary, and verify that all are still legible. Any illegible or missing markings must be replaced. Replacements can be obtained by contacting Thermo Products.
