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 the hoses off of the air switch. The burner should shut off almost immediately.

d.Reattach hoses. Burner should re-ignite after pre-purge time delay. NOTE: Ignition control may have to be reset after this portion of the test.

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

11.Check to see that the high limit control is set above the design temperature requirements of the system. For multiple zones: Check to make sure the flow is adjusted as required in each zone.

12.Check that the heater is cycled with the thermo- stat. Raise the setting on the thermostat to the highest setting and verify that the heater goes through the normal start-up cycle. Reduce to the lowest setting and verify that the heater goes off.

13.Observe several operating cycles for proper oper- ation.

14.Set the heater thermostat to desired temperature.

15.Review all instructions shipped with this heater with owner or maintenance person, return to enve- lope and give to owner or place the instructions inside front panel on heater.
