SECTION XVI - Maintenance Procedures

MAINTENANCE PROCEDURES

WARNING

The PERFORMANCE PLUS should be inspected and serviced annually, prefer- ably at the start of the heating season, by a qualified service technician. In addi- tion, the maintenance and care of the unit as outlined on page 58 and further explained on pages 59 through 62 should be performed to assure maximum effi- ciency and reliability of the unit. Failure to service and maintain the PERFOR- MANCE PLUS and the system compo- nents could result in equipment failure, causing possible severe personal injury, death or substantial property damage.

NOTICE

The following information provides detailed instruction for completing the maintenance items outline in the mainte- nance schedule on page 58. In addition to this maintenance, the PERFOR- MANCE PLUS should be serviced at the beginning of the heating season by a qualified service technician.

Reported Problems

Any problems reported by the owner should be checked, verified and corrected before proceeding with any maintenance procedures.

Check the Surrounding Area

Verify that the area surrounding the PER- FORMANCE PLUS is free of combustible

/flammable materials or flammable vapors or liquids. Remove immediately if found.

Verify that air used for combustion is free of any contaminates. Refer to the list of potential materials listed on page 7 of this manual. If any of these products are in the room from which the unit takes its com- bustion air, they must be removed immedi- ately or the combustion air intake must be relocated to another area.

Inspect the Burner Area

Remove the burner hood and inspect the appearance of the burner components.

Vacuum any dirt or debris from the burner components.

Remove the venturi inlet elbow to check for dirt and debris. Remove any obstructions.

WARNING

Do not use solvents to clean any of the burner components. The components could be damaged, resulting in unreli- able or unsafe operation.

Check System (Primary and Domestic) Piping

Inspect all piping on the Primary Heating system and the Domestic system for leaks and verify that the piping is leak free.

Inspect the fittings and components on the unit and verify they are leak free.

WARNING

Eliminate all primary water system leaks. Continual fresh make-up water will reduce the outer tank life causing tank failure. Leaking water may also cause severe property damage to the surround- ing area.
