Troubleshooting the Gas control System

NOTE

: Before trouble shooting the gas control system, be sure external gas shut off is in the “On” position.

SIT NOVA 820 MILLIVOLT VALVE

Symptom

1. Spark ignitor will not light

2. Pilot will not stay lit after

carefully following lighting

instructions

3. Pilot burning, no gas to

main burner

4. Frequent pilot outage

problem

possible causes

A. Defective or misaligned electrode

at pilot

B. Defective ignitor (Push Button)

A. Defective pilot generator (thermo-

couple), remote wall switch

B. Defective automatic valve

A. Wall switch or wires defective

B. Thermopile may not be generat-

ing sufficient millivoltage

C. Plugged burner orifice

D. Defective automatic valve opera-

tor

A. Pilot flame may be too low or

blowing (high) causing the pilot

safety to drop out

B. Possible blockage of the vent

terminal

corrective Action

Using a match, light pilot. If pilot lights, turn off pilot and

push the red button again. If pilot will not light - check

gap at electrode and pilot-should be 1/8” to have a strong

spark.
With the control knob in the pilot position, push the control

knob all the way and hold. Check for spark at electrode

and pilot. If no spark to pilot, and electrode wire is properly

connected, replace the battery in the ignitor module and

try again. Refer to Maintenance Section. If the problem

still exists, replace the ignitor module box.
Check pilot flame. Must impinge on thermocouple/ther-

mopile. NOTE: This pilot burner assembly utilizes both

a thermocouple and a thermopile. The thermocouple

operates the main valve operation (On and Off). Clean

and or adjust pilot for maximum flame impingement on

thermopile and thermocouple.
Turn valve knob to “Pilot”. Maintain flow to pilot; millivolt

meter should read greater than 10mV. If the reading is

okay and the pilot does not stay on, replace the gas valve.

NOTE: An interrupter block (not supplied) must be used

to conduct this test.
Check wall switch and wires for proper connections.

Jumper wire across terminals at wall switch, if burner

comes on, replace defective wall switch.. If okay, jumper

wires across wall switch wires at valve, if burner comes

on, wires are faulty or connections are bad.
1. Be sure wire connections form thermopile at gas valve

terminals are tight and thermopile is fully inserted into

pilot bracket.

2. One of the wall switch wires may be grounded. Re-

move wall switch wires form valve terminals if pilot

now stays lit, trace wall switch wiring for ground. May

be grounded to fireplace or gas supply.

3. Check thermopile with millivolt meter. Take reading

at thermopile terminals of gas valve. Should read

250-300 millivolts (minimum 150) while holding valve

knob depressed in pilot position and wall switch “Off”.

Replace faulty thermopile if reading is below specified

minimum.

Check burner orifices for debris and remove.
Turn valve knob to “On”, place wall switch to “On” millivolt

meter should read greater than 150mV. If the reading is

okay and the burner does not come on, replace the gas

valve.
Clean and/or adjust pilot flame for maximum flame im-

pingement on thermopile and thermocouple.

Check the vent terminal for blockage (recycling the flue

gases).
