Trouble Shooting
IF NO SPARK FROM ELECTRODE OR IF GAS VALVE DOES NOT
WORK THEN
a.
Check your power supply. Should have 24 volts between
power wires. Use a voltage meter between inlet 24 volts wire
and ground terminal at electrode plate to measure 24 volts.
b.
Check continuity. Use ohmmeter. For example, check
resistance between valve wire and ground. Should show
almost no resistance. (0 ohms) through valve. If high
resistance, check wire connectors.
c.
Check spark gap. Should be 7/64” (.109”) between electrode
tip ground stop. If gap is too large, spark will occur at wrong
location. If gap is too small, spark may not be hot enough to
light pilot burner.
d.
Be sure connectors are fully inserted into ignition control. (See
Wiring Diagram on rating plate).
IF INSUFFICIENT GAS FLOW THEN
a.
Gas manual valve not full “ON”. Turn valve handle to full “ON”
position.
b.
Burner orifice plugged. Remove heater top, remove burner orifice
(use ½” hex wrench) and thoroughly clean. Spiders often crawl into
orifice hole and make a web, blocking the orifice.
