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, and/or soot deposits collected on logs.

a. Flame impingement on logs incorrect.

—Check and adjust log position. See Page 17. 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.
