TROUBLE SHOOTING THE GAS CONTROL SYSTEM

SIT NOVA 820 MILLIVOLT VALVE

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

WARNING: BEFORE DOING ANY GAS CONTROL SERVICE WORK, REMOVE GLASS FRONT.

SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION

1. Spark ignitor will not light A. Defective or misaligned Using a match, light pilot. If pilot lights, turn off pilot and

electrode at pilot. 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.

B. Defective ignitor (Push Button) Push Piezo Ignitor Button. Check for spark at electrode and

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

connected, replace ignitor.

2. Pilot will not stay lit after A. Defective pilot generator 1. Check pilot ame. Must impinge on thermocouple/

carefully following lighting (thermocouple), remote wall thermopile. Note: this pilot burner assembly utilizes both-

instructions. switch. a thermocouple and a thermopile. The thermocouple

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

and or adjust pilot for maximum ame impingement on

thermopile and thermocouple.

B. Defective automatic valve Turn valve knob to "Pilot". Maintain ow to pilot; mil

liv olt meter should read greater than 10 mV. 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.

3. Pilot burning, no gas to A. Wall switch or wires defective Check wall switch and wires for proper connections.

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.

B. Thermopile may not be 1. Be sure wire connections from thermopile at gas valve

2. One of the wall switch wires may be grounded. Remove

wall switch wires from valve terminals if pilot now stays

lit, trace wall switch wiring for ground. May be grounded

to replace 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 de-

pressed in pilot position and wall switch "Off". Replace

faulty thermopile if reading is below specied minimum
