C. Ignitor.

Check the spark at the electrode and pilot. If no spark and electrode

 

 

 

wire is properly connected, replace the ignitor. Verify that there is no

 

 

short in electrode wire.

 

D. Pilot or misaligned electrode

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

trigger the piezo ignitor button again. If the pilot lights, an improper

 

 

gas/air mixture caused the bad lighting and a longer purge period

 

 

is recommended. If the pilot will not light, ensure the gap at the

 

 

electrode and pilot is one-eighth inch to have a strong spark. If the

 

 

gap is OK, replace the pilot.

 

 

 

2. The pilot will not stay lit

A. Thermocouple.

Check that the pilot flame impinges on the thermocouple. Adjust the

Ensure that the thermocouple connection at the gas valve is fully

 

 

 

 

inserted and tight (hand tighten plus 1/4 turn).

 

 

Verify proper voltage output from the thermocouple to the valve.

 

 

Place one millivolt meter lead wire on the thermocouple copper lead.

 

 

Place the second lead wire on the solder button on the back of the

 

 

valve (blue wire). Start the pilot and hold the valve knob in. The

 

 

millivolt reading should read 8-16 millivolts. If millivolt reading is less

 

 

than 8 millivolts, replace thermocouple.

 

 

 

 

B. Improper gas inlet pressure.

Natural gas should be 5-7 in. w.c. LP should be 11-14 in. w.c. Verify

 

 

pressure with manometer.

 

C. Valve.

If the thermocouple is producing 8-16 millivolts, replace control valve.

 

 

 

3. The pilot is burning, there

pilot bracket.

 

 

Check the thermopile with a millivolt meter. Take the reading at

 

 

TH-TP&TP terminals of the gas valve. The meter should read 350

 

 

millivolts minimum, while holding the valve knob depressed in the

 

 

pilot position, with the pilot lit, and the ON/OFF switch in the OFF

 

 

position. Replace the thermopile if the reading is below the specified

 

 

minimum.

 

 

With the pilot in the ON position, disconnect the thermopile leads

 

 

from the valve. Take a reading at the thermopile leads. The reading

 

 

should be 350 millivolts minimum. Replace the thermopile if the

 

 

reading is below the minimum.
