CHAPTER 17 - MAINTENANCE PROCEDURES

17.1. Service Technician Maintenance Procedures

WARNING
The PRESTIGE Excellence must be inspected
and serviced annually, preferably at the start
of the heating season, by a qualified service
technician. In addition, the owner main-
tenance and care of the unit as outlined in
Chapter 16 on page 67 and further explained
in the Prestige User's Information manual
should be performed to assure maximum
efficiency and reliability of the unit. Failure
to service and maintain the PRESTIGE Excel-
lence and the system components can result
in equipment failure, resulting in substantial
property damage, serious injury, or death.
NOTICE
The following information provides detailed in-
structions for completing the service technician
maintenance items outline in the maintenance
schedule of Chapter 16 on page 67.

17.2. Reported Problems

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

17.3. Check Surrounding Area

• Verify that the area surrounding the PRESTIGE Excel-
lence is free of combustible / flammable materials or
flammable vapors or liquids. Remove immediately if
found.
• Verify that combustion air inlet area is free of any
contaminates. Refer to the materials listed in Sec-
tion 2.1 on page 3 of this manual. If any of these
products are in the area from which the unit takes
its combustion air, they must be removed immedi-
ately or the combustion air intake must be relocat-
ed to another area.

17.4. Inspect Burner Area

• Remove the boiler front jacket panel and venturi
inlet elbow.
• Vacuum any dirt or debris from the burner/blower
components.
• Check the burner plate mounting nuts for tight-
ness, see Section 17.24 on page 72 for torque
specification.
• Check burner plate gasket for discoloration or damage.
• Check for flue gas leakage where the condensate
pan connects to the heat exchanger and at the top
and bottom of the internal vent pipe.
• Re-install venturi inlet elbow and front jacket panel
when completed.
WARNING
Do not use solvents to clean any of the burn-
er components. The components could be
damaged, resulting in unreliable or unsafe
operation. Failure to comply with this in-
struction can result in substantial property
damage, serious injury, or death.

17.5. Check System Piping

• Inspect all water and gas piping for leaks and verify
that the piping is properly supported.
• Inspect the fittings and components on the unit
and verify they are leak free.
WARNING
Eliminate all system water leaks. Continual
fresh make-up water will reduce the heat ex-
changer life causing boiler failure. Leaking
water may also cause severe property dam-
age to the surrounding area. Inspect the gas
supply piping using the procedure outlined in
Section 11.3.4 on page 56. Failure to comply
with this instruction can result in substantial
property damage, serious injury, or death.

17.6. Clean Condensate Drain Assembly

• Loosen the retaining nut from the condensate drain
assembly and disconnect the assembly from the boiler.
• Empty any water from the trap and flush with fresh
water as necessary to clean.
• Remove plastic ball and clean with fresh water.
• Check the drain piping from the condensate drain
assembly to the drain. Flush to clean as necessary.
• Install the plastic ball into the condensate drain
assembly and reassemble onto the boiler by tight-
ening the retaining nut with rubber seal onto the
boiler. Hand tight only.
• Remove the fill plug on the condensate drain as-
sembly and fill with water. See Fig. 12 on page 24.
• Replace the fill plug on drain assembly.
