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.

Inspect the condensate drain line, condensate PVC

 

fittings, and condensate trap.

2.

Remove the PVC cap retaining screw from the PVC cap

 

(FIG. 2-1).

3.

Remove the 2 inch PVC cap with the switch located at the

 

top of the trap (FIG. 2-1).

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.

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

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 6 - Gas Connections of the SYNC Installation and Operation

7. Replace the retaining screw.
