– 13 –
Where appliance instructions differ from this manual, follow the appliance instructions.
Should overheating or an emergency occur, immediately:
• Shut off main manual gas valve.
• Shut off control switch to burner.
Under some circumstances power should remain on for
circulating blowers or other equipment. Determine proper
response before attempting start-up.
If burner fails ignition on several attempts, close gas valve
and use burner blower to purge appliance before restart.

Model 60200FR diagnostic LED’s
– Amber OFF – Red OFF – Green OFF
– Amber ON – Red ON – Green ON
– Amber FLASHING – Red FLASHING
– Amber BLINKING (blinks off momentarily every 3 to 4 seconds)
Please see 60200FR control label for trial for ignition (TFI)
and purge timings.
Start-up & operation
Do not start the burner if the combustion chamber
contains residual gas. Allow gas to disperse.
Per UL requirements, the control will not turn on if the
flame rod senses flame during the self-test. If the flame
rod senses flame, the green LED turns on. The control
will remain in self-test mode until the flame rod no
longer senses flame. The amber LED will remain on,
but blink off momentarily every 3 to 4 seconds.
flame rod senses flame. Amber and red LED’s are off
and green LED is on during normal running.
Lockout If the flame rod does not sense flame within the TFI
time limit after gas valve activation, lockout occurs.
The control turns the red LED on constant, and closes
the alarm contact. Green LED is off.
To Reset Push in and hold reset button for 1 second, then release.
Latch-up If the control locks out 3 times during a single call for
heat, latch-up occurs. The control turns on both the
amber and red LED’s constant. You must use the special
procedure below to reset the control after latch-up.
Reset from latch-up — Only a qualified service techni-
cian should attempt to reset the control after latch-up.
The problem that caused the repeated burner prob-
lems must be corrected before returning the burner
to normal operation.
Push in and hold the reset button for about 10 seconds.
The red and amber LED’s will flash alternately.
After the LED’s begin flashing, continue to hold the
reset button for about another 20 seconds. The LED’s
will turn off. Release the reset button and the control
will restart. (Releasing the button before the LED’s turn
off will cause the control to remain in latch-up.)
The 60200FR control will not reset from lockout or
latch-up if power is interrupted.
Power ON Open all manual gas line valves. Close the line switch.
(If Red LED turns on constant , control is in lockout.
See below to reset.)
Self-test 1 The control performs a “boot-up” test to verify internal
operation each time power is applied to the red/white
wire. About 4 seconds after power application, the
amber LED turns on. The test continues for about 6 more
seconds. If the test fails, the control turns the amber
LED off and repeats this test sequence until successful.
Stand-by (No call for heat) If Self-test 1 is successful, amber LED
turns off and control waits for heat call.
Call for heat Set operating control and all limit controls to call for
heat. The 60200FR thermostat circuit must be closed
(jumpered) and power coming to black wire from limits.
Self-test 2 The amber LED turns on. For the first 3 to 4 seconds,
the control performs a self-test. If the flame rod senses
flame, the green LED turns on. The control repeats the
self-test until flame is no longer detected (green LED
would turn off). During this time, the amber LED will
remain on, but blink off momentarily every 3 to 4
seconds. If the control detects motor contacts closed
or power to the gas valve, lockout occurs.
Burner on After the self-test, the amber LED turns off. The motor
starts.
Pre-purge The ignitor starts after the pre-purge period. Two
seconds later, the gas valve opens. The 2-second
delay (ignition establishment period) helps ensure a
stable spark is in place when the gas valve opens (to
compensate for sluggish response of some AC ignition
transformers).
TFI After gas valve opens, the flame rod must sense flame
within the TFI time limit (trial for ignition). The green
LED turns on at the end of the TFI if the flame rod
senses flame.
Run The burner continues firing during call for heat if the
Flame failure If the flame rod loses flame signal during operation
(after the TFI), the red LED flashes. The gas valve closes
within 2 seconds. The motor remains on for the post-
purge period, then shuts off. Recycle: Control waits for
65 seconds (with red LED flashing), then begins again
at Self-test 2. Red LED goes off .
(NOTE: Controls with non-recycle feature will lock
out on flame failure.)
Post-purge Set operating control(s) and limit(s) to stop call for heat.
The gas valve will turn off within 2 seconds. The motor
remains on for the post-purge period, then turns off.
Stand-by Control remains in stand-by mode until limit circuit
sends power to the black wire and thermostat circuit
closes (or jumpered) — (call for heat).
