STANdING PILOT TROUBLESHOOTING

With proper installation and maintenance, your new Gas Fireplace will provide years of trouble-free service. If you
do experience a problem, refer to the Trouble Shooting Guide below. This guide will assist a qualified service person
in the diagnosis of problems and the corrective action to be taken.
1. Spark ignitor will not light pilot after repeated triggering
of piezo ignitor button.
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.
—Check remote shut off valves from fireplace. Usually
there is a valve near the main. There can be more than
one (1) 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.
c. No propane in tank.
—Check propane tank. Refill tank.
2. Pilot will not stay lit after carefully following lighting
instructions.
a. Defective thermopile.
—Check that pilot flame impinges on thermopile. Clean
f i r e - p a r t s . c o m
and/or adjust pilot for maximum flame impingement.
—Ensure the thermopile connections at the gas valve
are fully tight.
3. Pilot burning, no gas to burner, valve knob "ON."
a. Wall switch, remote control or wires defective.
—Check 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.
b. Thermopile may not be generating sufficient millivolts.
—If the pilot flame is not close enough physically to
the thermopile, adjust the pilot flame.
—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 switch in the OFF position.
Replace the faulty thermopile if the reading is below
the specified 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.
d. Plugged main burner orifice.
—Check main burner orifice for blockage and remove.
e. Blocked flue. Locate the manual reset temperature
switch. The base of the switch and the two mounting
screws are visible behind the screen on the left side
of the draft baffle (see parts list). Reach inside the
draft baffle, find the reset button located between the
electrical terminals and press it. The switch will click
to indicate is has been reset.
4. Frequent pilot outage problem.
a. Pilot flame may be too high or too low, or blowing (high),
causing pilot safety to drop out.
—Clean and adjust flame for maximum flame
impingement on the thermocouple. Follow lighting
instructions carefully.
5. The pilot and main burner extinguish while in operation.
a. No propane in tank.
Check propane tank. Refill fuel tank.
b. Bad thermopile or thermocouple.
—Replace if necessary.
c. Improper vent cap installation.
—Check for proper installation and freedom from debris
or blockage.
6. (Glass) Sooting
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.
