56701 Troubleshooting - kozy heat Thief River Falls-TRF 56701 Installation And Operation Manual

CAUTION: THE FOLLOWING MUST BE PERFORMED BY A
QUALIFIED TECHNICIAN
NO SPARK FROM ELECTRODE TO PILOT WHEN PIEZO BUTTON IS TRIGGERED.
A. Check wiring at back of piezo for proper connection.
B. Check wiring at electrode for proper connection.
C. Check position of electrode (1/8" (3 mm) between electrode and pilot). Readjust if necessary.
D. Look for arc below electrode and along electrode wire. Direct metal contact may cause an arc below electrode.
SPARK IGNITOR WILL NOT LIGHT AFTER REPEATED TRIGGERING OF PIEZO BUTTON.
A. No gas or low gas pressure.
♦ Check remote shut off valves from fireplace. Usually there is a valve near the main. There may be more than (1) valve between the fire
place and the main.
♦ Low gas pressure can be caused by several situations such as a bent line, too narrow diameter pipe, or low line pressure. Consult with
plumber or gas supplier.
B. No LP in tank.
♦ Check LP (propane) tank. Refill if necessary
PILOT WILL NOT STAY LIT AFTER CAREFULLY FOLLOWING LIGHTING INSTRUCTIONS.
A. Check that pilot flame impinges on thermocouple. Clean and / or adjust pilot for maximum flame impingement.
B. Ensure the thermocouple connection at gas valve is fully inserted and tight (hand tight plus 1/4 turn).
C. Thermocouple reading below 15 millivolts.
♦Disconnect thermocouple from valve, place one millivolt meter lead wire on the end of the thermocouple and the other millivolt meter
lead wire on the thermocouple‟s copper wire. Start pilot while holding valve knob in. If the millivolt reading is less than 15 millivolts,
replace the thermocouple.
.
D. Thermopile not generating sufficient millivolts.
♦ Pilot flame must be enveloping thermopile. Adjust pilot flame if necessary.
♦ Check thermopile wire connections at valve. Tighten if necessary.
♦ Check thermopile with millivolt meter. Turn remote / thermostat / wall switch or ON/OFF switch to OFF. Turn valve knob to PILOT
position (pilot should remain lit). Take reading at THTP & TP terminals on gas valve. Reading should be 350 millivolts minimum.
Replace thermopile if reading falls below specified minimum.
