All installations and services must be performed by qualified service personnel.

V. DEALER MAINTENANCE

A. ELECTRICAL:

1.Check all wiring for loose connections.

2.Check for correct voltage at the furnace when operating.

3.Check amp-draw on blower motor and burner to assure they are not exceeding name plate amp rating.

B. CLEANING HEAT EXCHANGER:

WARNING: THE HEAT EXCHANGER MUST BE CLEANED BY A QUALIFIED SERVICE TECHNICIAN.

It is important to inspect and clean the heat exchanger once a year or as necessary to remove any build-up of soot. A layer of soot on the inside of the heat exchanger will act as an insulator and reduce heat transfer, resulting in less efficiency. If heavy soot deposits were found in the heat exchanger, this indicates that the burner may be out of adjustment. Reset the burner as indicated under the "BURNER COMBUSTION" section.

To clean the heat exchanger, first turn off all power to the unit. Next, remove the access panel (see below and following page) immediately above the burner (on the horizontal furnace, it will be located to the side of the burner) to gain entry to the cleanout covers. (Please notice: This panel is identified with a label.) Remove cleanout covers, the vent connector pipe to the chimney, the burner, and the burner mounting plates. When removing the cleanout covers, special care must be taken not to damage the gaskets. Should the gaskets separate, crack, break, or otherwise not be able to provide the necessary seal, the gasket must be replaced before reattaching the cleanout covers.

With access to the inside of the heat exchanger through the burner area, cleanout openings, and vent pipe connection, it is now possible to use a long, flexible wire brush and an industrial type vacuum cleaner to remove any soot build- up. NOTE: A one inch (outside diameter) vacuum cleaner hose will fit into the outer radiator.

To vacuum and brush the outer radiator of the heat exchanger, go through the cleanout openings in both directions, as shown below.
