2 Maintenance

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 2A 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

DRAIN ON BOILER

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

1” PVC / CPVC CONNECTION

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.

Inspect boiler interior

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

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

Clean condensate trap

1.Inspect the condensate drain line, vent line, condensate PVC fittings, and condensate trap.

Flush condensate trap with water

1.Remove the four (4) screws securing the top cover to the condensate trap and remove the cover (FIG. 2-1).

2.Locate the plastic ball inside the float tube. Verify there is nothing under the ball causing it to not seat properly.

3.Fill with fresh water until the water begins to pour out of the drain.

4.Replace the top cover and the screws removed in Step 1.

Check all piping for leaks

WARNING Eliminate all system or boiler leaks. Continual fresh makeup water will

reduce boiler life. Minerals can build up, 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 6 - Gas Connections of the Crest Installation and Operation Manual.
