POSSIBLE CAUSE
CORRECTIVE MEASURE
Gas odor during setup
Gas Leak
WHAT TO DO IF YOU SMELL GAS
Do not try to light any appliance.
Do not touch any electrical switch;
do not use any phone in your building.
Leave the building immediately.
Immediately call your gas supplier from
a neighbor’s phone. Follow the gas
supplier’s instructions.
If you cannot reach your gas supplier, call
the fire department.
Gas odor before first ignition
Gas Leak
Spark ignitor will not light pilot after
repeated triggering of piezo ignitor
button.
Defective ignitor (no spark electrode)
Check for spark at electrode and pilot; if
no spark and electrode wire is properly
connected, replace ignitor.
No gas or low gas pressure.
Check remote shut-off valves from
fireplace. Usually there is a valve near the
main. There can be more than one valve
between the fireplace and main.
Low pressure can be caused by a variety
of situations such as a bent line, too narrow
diameter of pipe, or low line pressure.
Consult with plumber or gas supplier.
No Propane in tank.
Check Propane tank. Refill tank.
Pilot will not stay lit after carefully
following lighting instructions.
Defective thermocouple.
Check that pilot flame impinges on
thermocouple. Clean and/or adjust pilot
for maximum flame impingement.
Ensure the thermocouple connection at the
gas valve is fully inserted and tight (hand tight
plus 1/4 turn). Faulty thermocouple if reading
is below specified minimum of 15 millivolts.
Disconnect the thermocouple from the valve,
place one millivolt meter lead wire on the end
of the thermocouple and the other millivolt
meter lead wire on the thermocouple copper
wire. Start the pilot and hold the valve knob
in. If the millivolt reading is less than 15
millivolt, replace the thermocouple.
Defective valve.
If thermocouple is producing more than 15
millivolts, replace faulty valve.
