Address reported problems

Figure 2-1Condensate Trap

1.Inspect any problems reported by the owner and correct before proceeding.

Inspect water heater area

1.Verify that water heater 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 Armor Water Heater Installation and Operation Manual. If any of these are present in the water heater intake air vicinity, they must be removed. If they cannot be removed, reinstall the air and vent lines per this manual and the Armor Water Heater Installation and Operation Manual.

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.

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.

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.

Check all piping for leaks

WARNING Eliminate all system or water heater leaks. Leaking water may 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 Armor Water Heater Installation and Operation Manual.
