Verify burner/appliance operation
(Massachusetts Code burners)
Check burner/appliance/controls operation
Test operating and limit controls on appliance as specified in appliance
instruction manual.
Check operation of the 60200FR primary control by forcing Latch-up (three
consecutive lockouts during the same call for heat): Close the main manual
gas cock. Temporarily jumper the low gas pressure switch. Then cycle
the burner. Press the reset button to reset when the 60200FR control
locks out on flame failure. Do this two times and the control should enter
Latch-up. See page 17 to reset control. Remove the jumper from the low
gas pressure switch.
Verify that the burner starts in low fire, then goes to high fire after 8
seconds. (The time-delay relay delays power to the gas valve second
stage for 8 seconds.)
Check the airflow switch
Cycle the burner off with the appliance controls. Then turn off power to
the appliance. Remove both of the sensing lines from the airflow switch by
loosening the plastic sealing nuts and pulling the aluminum sensing tubes
out of the socket.
With the sensing lines removed, turn on power to the appliance and set the
controls to call for heat. Watch the manometer on the manual gas valve outlet
pressure tap. After the control performs its pre-purge, it will try to turn on
the gas valves. The gas valves should not open with the airflow sensor lines
removed. Set the controls to stop the call for heat and turn off power to the
appliance. If the airflow switch operates correctly (gas valves don't open),
continue with normal operation. If the airflow switch fails to operate correctly,
replace the switch and retest.
NEVER attempt to adjust the air pressure switch setting. This
could allow unsafe operation of the burner, resulting in potential of
severe personal injury, death or substantial property damage.
Check high gas pressure switch
Cycle the burner off with the appliance controls and turn off power to
the appliance/burner.
Attach a manometer to the manifold-side manual gas valve test port.
Turn on power and cycle the burner on with the appliance controls.
Measure the manifold gas pressure with the manometer.
Set the high gas pressure switch to a pressure less than actual manifold
pressure. The high gas pressure switch should shut the burner down.
Replace the switch if necessary.
Turn off power to the appliance/burner; remove the manometer and
replace the plug in the gas valve test port. Reset switch.
Check low gas pressure switch —
Cycle the burner off with the appliance controls and turn off power to
the appliance/burner.
Close the main manual gas valve.
Cycle the burner on.
The low gas pressure switch should shut the burner down. Replace the
switch if necessary.
Turn off power to the appliance/burner.
Open the main manual gas valve.
Reset low gas pressure switch.

Check flange door switch
Cycle the burner off with the appliance controls and turn off power
to the appliance/burner.
Remove the nuts securing the hinged flange and swing the flange
open.
Attempt to cycle the burner with the appliance controls.
The flange door switch should prevent the burner from operating.
Replace the switch if necessary.
Close the flange door and replace the nuts.
Verify burner operation
Start and stop the burner several times, allowing the primary
control to sequence through normal operation. Verify correct
operation of burner and controls throughout, including the burner
door switch and high and low gas pressure switches.
Verify vent system operation
Verify vent is operating correctly and flue products are properly
exhausted from building.
Check operation of barometric damper and spill switch.
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.
Prepare the burner for normal operation
Cycle burner off with appliance controls. Then turn off power to
the appliance.
Close the main manual gas valve.
Verify all components and wires are in place and burner is ready
for operation.
When all tests and checks are completed, restore the burner and
appliance to normal condition for operation.
Start the burner again to verify proper operation before leaving.
Train the user
Train the user to operate the burner and appliance under normal
conditions. Explain procedure to shut down burner/appliance
when required.
Review the user information manual (and the appliance instruc-
tions) with the user.
Verify the user is aware of all procedures specified in the
manual.
Verify user will not store or use combustible liquids or materials
or contaminants in the vicinity of the burner/appliance.
