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 the Knight Wall Mount Installation and Operation 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 Installation and Operation 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.

Clean condensate trap

1. Remove the clean out cap on the bottom of the trap. Let the

condensate and any debris drain out.

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.

Check all piping for leaks

2.	Fill with fresh water until the water begins to pour out of the
	drain.
3.	Replace the clean out cap and resume operation.

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.

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 of the Knight Wall Mount Installation and Operation Manual.
