Inspect water heater interior

1.Remove the front access cover and inspect the interior of the water heater.

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

￿WARNING

The condensate trap must be filled with water during all times of water heater operation to avoid flue gas emission from the condensate drain line. Failure to fill the trap could result in severe personal injury or death.

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.

7.Replace the retaining screw.
