STANDING PILOT TROUBLESHOOTING

a. Defective ignitor (no spark electrode)
—Check for spark at electrode and pilot; if no spark and
electrode wire is properly connected, replace ignitor.
b. No gas or low gas pressure.
is a valve near the main. There can be more than one (1)
—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.
c. No LP in tank.
2. Pilot will not stay lit after carefully following lighting
instructions.
a. Defective thermocouple.
—Ensure the thermocouple connection at the gas valve
is fully inserted and tight (hand tight plus 1/4 turn). Faulty
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.
b. Defective valve.
—If thermocouple is producing more than 15 millivolts, replace
faulty valve.
OFF/ON switch "ON."
a. REMOTE/OFF/ON switch, wall switch, remote control or
wires defective.
—Check REMOTE/OFF/ON switch and wires for proper
connections. Place jumper wires across terminal at switch.
If burner comes on, replace defective switch. If OK, place
jumper wires across switch wires at gas valve-if burner comes
on, wires are faulty or connections are bad.
—Be sure the wire connections from the thermopile at the gas
valve terminals are tight and the thermopile is fully inserted
into the 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 REMOTE/OFF/ON switch in the OFF position. Replace
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.

c. Defective valve.
—Turn valve knob to ON. Place REMOTE/OFF/ON switch
to ON. Check with millivolt meter at thermopile terminals.
Millivolt meter should read greater than 200 millivolts. If the
reading is okay and the main burner does not ignite, replace
the gas valve.

on the thermocouple. Follow lighting instructions carefully.
a. No LP (Propane) in tank.
b. Inner vent pipe leaking exhaust gases back into system
—Check for leaks.
c. Glass too loose, gasket leaks in corners after usage.
—Be certain glass assembly is installed correctly.
d. Horizontal vent improperly pitched.
—The horizontal vent cap should slope down only enough
to prevent any water from entering the unit. The maximum
downwards slope is 1/4 inch.
e. Bad thermopile or thermocouple.
—Replace if necessary.
f. Improper vent cap installation.
—Check for proper installation and freedom from debris or
blockage.
6. Glass soots.
a. Flame impingement on logs.
—Check and adjust log position. Contact Empire Comfort
Systems, Inc.
b. Debris around throat of main burner.
—Inspect the opening at the base of the main burner. It is
imperative that NO material be placed in this opening.
—Check to make sure vent cap is installed properly and free
of debris. Make sure that vent system joints are tight and
have no leaks.
—Check to make sure that no material has been placed at
the main burner base.
