■ For thermocouples using a mounting clip, ensure
the thermocouple is completely pushed into its
bracket when replacing. Failure to do so may
cause burner outage.
■ When connecting the thermocouple to the safety
control valve, thread the thermocouple fi nger tight
to the valve, then snug it in with a wrench.
To determine if the thermocouple is defective:
Connect an ohm meter between the ends of the
thermocouple.
-- A good thermocouple will show some level of
resistance from end to end.
-- A defective thermocouple will show an open
circuit on the ohm meter
