IV. Frequent pilot outage
problem.z
CORRECTIVE ACTION
With the pilot in the ON posi-
tion, disconnect the thermopile
leads from the valve. Take a
reading at the thermopile leads.
The reading should be 325 mil-
livolts minimum. Replace the
thermopile if the reading is be-
low the minimum.
1. Turn valve knob to “ON”. Place
ON/OFF switch to “ON”. Check
with millivolt meter at thermo-
pile terminals. Millivolt meter
should read greater than 100
m.v. If the reading is okay and
the burner does not come on,
replace the gas valve.
1. Check burner orifice for stop-
page and remove.
1. Follow corrective action in A.1
above; check switch and wiring.
Replace where defective.
1. Clean and adjust pilot flame for
maximum flame impingement
on the thermocouple. Follow
lighting instruction carefully.
POSSIBLE CAUSE
C. Defective valve.
D. Plugged burner orifice.
E. Wall switch, or wires defective.
A. Pilot flame may be too high or too
low, or blowing (high), causing
pilot safety to drop out.
