With proper installation and maintenance, your new Direct Vent 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 LP in tank.
—Check LP (propane) tank. Refill tank.
2. Pilot will not stay lit after carefully following lighting
instructions.
a. 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.
b. Defective valve.
—If thermocouple is producing more than 15 millivolts,
replace faulty valve.
3. Pilot burning, no gas to burner, valve knob “ON”, REMOTE/
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.
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 REMOTE/OFF/ON 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.
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 LP (Propane) in tank.
Check LP (Propane) tank. Refill fuel 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.
7. Flame burns blue and lifts off main burner.
a. Insufficient oxygen being supplied.
—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.
