dle valve to the test point B bleedle valve and open the upstream manual gas valve. Make sure that test point A & B bleedle valves have been opened so as to allow gas to flow. This will bring gas pressure to the second valve seat.

Fig. 54: Leak Test Procedure

5.Open the bleedle valve at test point C and connect a second rubber tube to it. Connect the other end of the tube to a manometer and look for a build-up of pressure. Increasing pressure indicates a leak- ing gas valve which must be replaced.

6.Remove rubber tube and manometers. Close each test point bleedle valve as the tubes are removed.

NOTE: Reinstall HGPS as applicable.

7.After no leakage has been verified at all valve seats and test valves, open downstream leak test valve and restore electrical power to the heater.

Post Start-Up Check

Check off steps as completed:

1.Verify that the heater and heat distribution units or storage tank are filled with water.

2.Confirm that the automatic air vent (if used) was opened two full turns during the venting proce- dure.

3.Verify that air has been purged from the system.

4.Verify that air has been purged from the gas pip- ing, and that the piping has been checked for leaks.

5.Confirm that the proper start-up procedures were followed.

6.Inspect burner to verify flame.

7.Test safety controls: If heater is equipped with a low water cut-off or additional safety controls, test for operation as outlined by manufacturer. Burner should be operating and should go off when con- trols are tested. When safety devices are restored, burners should re-ignite after pre-purge time delay.

8.Test limit control: While burner is operating, move indicator on high limit control below actual water temperature. Burner should go off while blower and circulator continue to operate. Raise setting on limit control above water temperature and burner should re-ignite after pre-purge time delay.

NOTE: Ignition control may have to be reset after this portion of the test.

9.Test ignition system safety device:

a.Open manual gas valve. Turn power on.

b.Set thermostat to call for heat.

c.When the heater is in operation, pull cap off of tee in air switch hose. The burner should go off almost immediately.

d.Reattach cap on tee. Burner should re-ignite after pre-purge time delay. NOTE: Ignition control may have to be reset after this por- tion of the test.

10.To restart system, follow lighting instructions in the Operation section.
