Check-Out Procedure

Check off steps as completed:

❏1. Boiler and heat distribution units filled with water?

❏2. Automatic air vent, if used, opened one full turn?

❏3. Air purged from system? Piping checked for leaks?

❏4. Air purged from oil piping? Piping checked for leaks?

❏5. Flue cap in place and tightened? Burner door closed, sealed and nut tight? Burner plugged in and service switch on?

Obtain gas-tight seal to prevent possible flue gas

leakage and carbon monoxide emissions, leading to severe personal injury or death.

❏6. Proper draft and burner flame? Final adjustment made with combustion test equipment?

❏7. Test limit control: While burner is operating, move indicator on limit control below actual boiler water temperature. Burner should go off while circulator continues to operate. Raise setting on limit control above water temperature and burner should re-ignite.

❏8. Test additional field-installed controls: If boiler has a low water cutoff, additional high limit or other controls, test for operation as outlined by manufacturer. Burner should be operating and should go off when controls are tested. When controls are restored, burner should re-ignite.

❏9. Limit control set to system temperature requirements (max. 220°F)?

❏10. For multiple zones, flow adjusted to distribute heat in all zones?

❏11. Thermostat heat anticipator setting (if available) set properly? Refer to “Connect wiring,” page 19.

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

❏13. Observed several operating cycles for proper operation?

❏14. Set room thermostat(s) to desired

room temperature?

❏15. Completed Installation and Service Certificate below?

❏16. Reviewed Maintenance and Service Manual with owner or maintenance person and instructed person to keep for future reference?

❏17. Returned all instructions provided with boiler to its envelope and placed with boiler for future reference?
