￿WARNING

Follow the Service and maintenance procedures given throughout this manual and in component literature shipped with the boiler. Failure to perform the service and maintenance could result in damage to the boiler or system. Failure to follow the directions in this manual and component literature could result in severe personal injury, death, or substantial property damage.

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 Wall Mount Service Manual.

Inspect boiler interior

1.Remove the front access cover and inspect the interior of the boiler.

2.Vacuum any sediment from inside the boiler and components. Remove any obstructions.

Inspect condensate trap

3.After the condensate trap is cleaned or serviced, it must be checked to ensure that it is installed and draining properly.

Monthly inspection:

1.	The condensate trap should be inspected monthly to
	ensure the trap is properly installed and connected to the
	condensate pipe under the boiler, see FIG. 12-1.
2.	The condensate line should be inspected monthly
	for obstructions, making sure it allows free flow for
	condensate to drain.
3.	Inspect the neutralizing kit (if installed) monthly to

￿WARNING

It is in the best interest of the end user to make sure the ball is present and the condensate trap is filled with water during all times of boiler operation to avoid flue gas emission from the condensate drain line. Failure to have the ball present or to fill the trap could result in severe personal injury or death.

ensure the condensate is draining properly, and there is

still an adequate amount of neutralizing agent available.

Check all piping for leaks

Annual cleaning:

1.	The condensate trap should be cleaned at least once
	annually, or at the end of each heating season, by
	removing the bottom cap and cleaning out any sediment
	that exists.
2.	The provided condensate trap is equipped with a ball
	that acts as a seal against harmful flue gases escaping in

￿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.

case there is no condensate in the trap. If this ball is not

present, flue gases may be able to pass through the trap

when there is no condensate present, resulting in an

unsafe environment. It is important to check and make

sure the ball is still located in the trap, acting as a seal

against flue gases at least once annually and after every

cleaning.

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.
