Verify burner/appliance operation
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) by closing
the main manual gas cock and cycling the burner. Press the reset button
to reset when the control locks out on flame failure. Do this two times
and the control should enter Latch-up. See page 12 to reset control.
❏ Check operation of airflow switch.
❏
Cycle the burner off with the appliance controls. Then turn off power to
the appliance. Remove the two sensing lines from the airflow switch by
loosening the plastic sealing nuts and pulling the aluminum sensing tubes
out of the sockets.
❏
With the sensing lines removed, turn on power to the appliance and set
the controls to call for heat. Watch the manometer on the combination
gas valve outlet pressure tap. After the control performs its pre-purge, it
will try to turn on the gas valve. The gas valve 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 valve doesn't open), continue with normal operation. If 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.
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 control throughout.
Verify burner/appliance operation
Verify vent system operation
❏ Verify vent is operating correctly and flue products are properly ex-
hausted from building.
❏ Check operation of barometric damper and spill switch.
❏ If the building contains any exhaust fans or conditions that could af-
fect vent performance, check burner/appliance/vent operation with
exhaust fans (or other conditions) operating.
Prepare burner for normal operation
❏ Cycle burner off with appliance controls. Then turn off power to the
appliance.
❏ Close the main manual gas valve.
❏ Remove the U-tube manometer line from the combination gas valve
outlet pressure tap hose barb. Remove hose barb and replace 1/8"
NPT pipe plug in tapping.
❏ Verify all components and wires are in place and burner is ready for
operation.
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 instructions)
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.
