Post Start-Up Check

Post Start-Up Check

Check off steps as completed:

1.Verify that the boiler 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.Testsafety controls: If boiler 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.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.

9.Check that the boiler is cycled with the thermostat. Raise the setting on the thermostat to the highest setting and verify that the boiler goes through the normal start-up cycle. Reduce to the lowest set- ting and verify that the boiler goes off.

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

11.Set the boiler thermostat to desired temperature.

12.Review all instructions shipped with this boiler with owner or maintenance person, return to envelope and give to owner or place the instructions inside front panel on boiler.

OPERATION

Lighting Instructions

1.Before lighting, make sure you have read all of the safety information in this manual.

2.Set the thermostat to the lowest setting.

3.Turn off all electrical power to the appliance.

4.This appliance is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand.

5.Turn on main manual gas valve field-installed near gas inlet connection on back of boiler.

6.Wait 5 minutes to clear out any gas. Then smell for gas, especially near the floor. If you then smell gas, STOP! Follow the steps in the safety informa- tion on the front cover of this manual. If you do not smell gas, go to next step.

7.Turn on all electrical power to the appliance.

8.Set thermostat to desired setting. The appliance will operate. The igniter will spark after the pre- purge time delay (15 seconds). The main valve should open. System will try for ignition up to four times (one time on optional single-try ignition mod- ule). If flame is not sensed, lockout will commence.

9.If the appliance will not operate, follow the instruc- tions “To Turn Off Gas ToAppliance,” and call your service technician or gas supplier.

10.If boiler fails to start, verify the following:

a.There are no loose connections or that the service switch is off.

b.High temperature limit switch or manual-reset high limit is not tripped.

c.Thermostat is set above water temperature.

d.Gas is on at the meter and the boiler.

e.Incoming dynamic gas pressure to the gas valve is NOT less than 4.0 in. WC for natural gas or propane gas.
