Draft may be pulling flame off
thermopile or thermocouple.
7
Pressure at burner manifold
should be 4.0" w.c. for natural
gas and 10.0" w.c. for propane
with all equipment on line in
full operation. If this cannot be
maintained, consult gas
company.
Gas pressure too low. 8
7Eliminate the draft.
Check millivoltage as above;
increase size of flame with
Unitrol pilot adjusting screw.
Remove and clean pilot and
thermopile or thermocouple;
decrease size of flame with
Unitrol pilot adjusting screw if
over 450 mv. Reading should
be 500 +/-50 mv. for
thermopile. Reading should be
between 25 and 35 mv. for
thermocouple.

SECTION 2S TROUBLESHOOTING CHART
Thermopile or thermocouple
producing insufficient
millivoltage.
33
Pilot will light but Unitrol
pilot gas valve will not hold
open automatically.
Check all wire connections.Loose wire connection in
millivoltage circuit.
5
Hold Unitrol knob (in PILOT
position) depressed for 1
minute or longer. Make sure all
air has been purged from gas
line.
Pilot thermopile or
thermocouple not hot enough
to generate required
millivoltage.
Check voltage at Unitrol with
millivoltmeter, holding pilot
flame on manually as in No. 1
above. Reading should be 500
+/-50 mv. for thermopile.
Reading should be between 25
and 35 mv. for thermocouple.
Check continuity across limit
control terminals with meter. If
limit control has cut off, check
at what temperature it cut off.
