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

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

9.Test ignition system safety device:

·Turn on manual gas valve. Turn power on.

·Set thermostat to call for heat.

·When the unit is in operation. Disconnect combustion air blower pressure switch, burner should go off immediately.

·Wait 5 minutes.

·Reconnect combustion air pressure switch, burner should reignite after pre-purge time delay.

10.To restart system, follow lighting instructions in Section O.

11.High limit control set to design temperature requirements of system? For multiple zones: flow adjusted as required in each zone?

12.Boiler cycled with thermostat? Raise to highest setting and verify boiler goes through normal start-up cycle. Reduce to lowest setting and verify boiler goes off.

13.Observed several operating cycles for proper operation?
