TEST SOLUTION
Turn up the pilot fl ame.
Replace pilot assembly.
Clean thermopile connection to the valve. Reconnect.
Replace thermopile / valve.
Shorten wire to connect length or wire gauge.
Replace.
Check for vent blockage.
Check joint seals and installation
Re-attach to fi replace.
Cap was not replaced.
Purge the gas line.
Fill the tank.
Turn up the pilot fl ame.
Gently twist the pilot head to improve the fl ame
pattern around the thermocouple.
Loosen and tighten thermocouple.
Clean thermocouple and valve connection.
Replace thermocouple.
Replace valve.
Replace.
Connect a jumper wire across the wall switch terminals;
if main burner lights, replace switch / thermostat.
Disconnect the switch wires & connect a jumper
wire across terminals 1 & 3; if the main burner lights,
check the wires for defects and / or replace wires.
Remove stoppage in orifi ce.
Replace.
Check if pilot can be lit by a match.
Check that the wire is connected to the push button igniter.
Check if the push button igniter needs tightening.
Replace the wire if the wire insulation is broken or frayed.
Replace the electrode if the ceramic insulator is cracked or broken.
Replace the push button ignitor
Fill the tank.
Spark gap should be 0.150" to 0.175" (5/32" to 11/64" approx.)
from the electrode tip and the pilot burner. To ensure proper
electrode location, tighten securing nut (fi nger tight plus 1/4 turn).
Check that the manual valve is turned on.
Check the pilot orifi ce for blockage.
Replace the valve.
Call the gas distributor.
