TROUBLESHOOTING

With proper installation and maintenance, your new Vented Fireplace Heater should provide years of trouble-free service. If you do experience a problem, refer to 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 depressing of piezo ignitor button.

a.Defective ignitor (no spark at 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 heater 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 of 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 thermopile.

-Check that pilot flame impinges on thermopile. Clean and/or adjust pilot for maximum flame impingement.

-Ensure that the thermopile connection at the gas valve is tight.

3.Pilot burning, no gas to burner, valve knob "ON", on/off switch "ON."

a."On/Off" switch, wall switch, or wires defective.

-Check "on/off" 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 milli- voltage.

-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 325 millivolts minimum, while holding the valve knob depressed the pilot position, with the pilot lit, and the ON/OFF 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 325 millivolts minimum. Replace the thermopile if the reading is below the minimum.

c.Defective valve.

-Turn valve knob to "ON." Place ON/OFF switch to "ON." Check with millivolt meter at thermopile terminals. Millivolt meter should read greater than 100 M.V. If the reading is okay and the burner does not come, replace the gas valve.

d.Plugged main burner orifice.

-Check main burner orifice for blockage, clean main burner orifice.

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 thermopile. 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.Bad thermopile.

-Replace if necessary.

c.Improper vent cap installation.

-Check for proper installation and freedom from debris or blockage.

6.Glass soots.

a.Flame impingement on logs.

-Adjust the log set so that the flame does not excessively impinge on it.

b.Improper air shutter adjustment.

-Adjust the air shutter.

7.Flame 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 burner base.
