Burner/appliance/controls operation
❏
Test operating and limit controls on appliance as specified in appliance
instructions.

Check operation of the primary control by forcing lockout to occur. For
primary controls that enter latch-up after multiple lockouts, force latch-up
to occur as well. Reset primary control per control data sheet instructions
after each test.
❏
Start and stop the burner several times, allowing the primary control to
sequence through normal operation. Verify correct operation of burner
and primary control throughout.
❏
Confirm and/or adjust overfire combustion pressure. Refer to boiler/
furnace manufacturer’s recommendations.
Verify vent system operation
❏
Verify vent is operating correctly and flue products are properly exhausted
from building. If the building contains any exhaust fans or conditions that
could affect vent performance, check burner/appliance/vent operation
with exhaust fans (or other conditions) operating.
