OBSERVED PROBLEM
Pilot will not stay lit after
carefully following the lighting
instructions
Pilot burning, no gas to burner,
valve knob "ON"
Frequent pilot/burner outage
problem
REMEDY
1. Check pilot flame, it must
impinge on thermocouple
(see Figure 13, page 11).
Clean and/or adjust pilot for
maximum flame impinge
-
ment on thermocouple.
Ensure that the connection
between the valve and
thermocouple are tight and
secure.
1. Check thermopile with mil
-
livolt meter. Take reading
at thermopile terminals of
gas valve. It should read
325 millivolts minimum.
Replace faulty thermopile
if reading is below specified
minimum.
2. Check burner orifice for
stoppage and remove
1. Clean and/or adjust pilot
flame for maximum flame
impingement on thermo-
couple (see Figure 13,
page 11)
POSSIBLE CAUSE
1. Defective pilot generator
(thermocouple)
1. Thermopile may not be
generating sufficient mil
-
livoltage.
2. Plugged burner orifice
1. Pilot flame may be too low
or blowing (high) causing
the pilot/valve safety to
drop out
