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. 11-1).

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.
