Problem

Possible Cause

Solution

Pilot will not light.

Air in gas lines.

Bleed all air from gas lines.

Wrong inlet pressure.

With the main burner functioning, adjust the inlet pressure

regulator to supply gas to the appliance within the design

parameters of the appliance manufacturer. (Typically 7”NG,

11”LPG).

Defective spark electrode.

Replace piezo wire if insulation is cracked or the tip is cor

roded.

Verify that the spark gap between the pilot and the electrode

is correct.

Defective piezo wire.

Replace piezo wire if insulation is damaged, or the wire is bro

ken or corroded.

Safety interlock function engaged. Allow thermocouple to cool until the mv drops below the hold-

in requirements of the safety magnet, (30 seconds or less).

Re-light pilot.

Pilot will not hold.

Wrong inlet pressure.

With the main burner functioning, adjust the inlet pressure

regulator to supply gas to the appliance within design

parameters of the appliance manufacturer. (Typically 7”NG,

11”LPG)

Pilot adjustment screw not

and only the thermo-generator wire connected to the main

operator head, measure the voltage across TPTH and TP.

This open circuit voltage should be between 500mv and

750mv. Tune the pilot adjustment screw until the mv reading

falls within these parameters. (Counter-clockwise increases
