The boiler should be inspected annually only by a qualiﬁed service technician. In addition, the maintenance and care of the boiler designated in Table 12A and explained on the following pages must be performed to assure maximum boiler efﬁciency and reliability. Failure to service and maintain the boiler and system could result in equipment failure.

Electrical shock hazard – Turn off power to the boiler before any service operation on the boiler except as noted otherwise in this instruction manual. Failure to turn off electrical power could result in electrical shock, causing severe personal injury or death.

Address reported problems

1.Inspect any problems reported by the owner and correct before proceeding.

Inspect boiler area

1.Verify that boiler area is free of any combustible materials, gasoline and other ﬂammable vapors and liquids.

2.Verify that air intake area is free of any of the contaminants listed in Section 1 of this manual. If any of these are present in the boiler intake air vicinity, they must be removed. If they cannot be removed, reinstall the air and vent lines per this manual and the Knight XL Service Manual.

WARNING The condensate trap must be ﬁlled with water during all times of boiler operation to

avoid ﬂue gas emission from the condensate drain line. Failure to ﬁll the trap could result in severe personal injury or death.

Clean condensate trap

Check all piping for leaks

1.	Inspect the condensate drain line, condensate PVC
	ﬁttings, and condensate trap.
2.	Remove the PVC cap retaining screw from the PVC cap
	(FIG. 12-1).
3.	Remove the 2 inch PVC cap with the switch located at the
	top of the trap (FIG. 12-1).

WARNING

Eliminate all system or boiler leaks. Continual fresh makeup water will reduce boiler life. Minerals can build up in sections, reducing heat transfer, overheating heat exchanger, and causing heat exchanger failure. Leaking water may also cause severe property damage.

4.	Remove any sediment in the trap.
5.	Fill with fresh water until the water begins to pour out of
	the drain.
6.	Replace the cap. Press the cap onto the trap until the cap
	makes contact with the drain.
7.	Replace the retaining screw.

1.Inspect all water and gas piping and verify to be leak free.

2.Look for signs of leaking lines and correct any problems found.

3.Check gas line using the procedure found in Section 7 - Gas Connections.
