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. Pilotburning,nogastoburner,valveknob“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. —WiththepilotintheONposition,disconnectthethermopile 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. —Cleanandadjustflameformaximumflameimpingementon 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. Page 34 17375-10-0706 17375-10-0706 Page 35 1. To wire Junction Box Receptacle, remove the tab on the side of the receptacle (hot side) to split receptacle. This will be required to separate blower and valve circuits. 2. Power for switched and live sides of Duplex Receptacle must come from the same power source. (One circuit breaker on main panel must switch all power off.) 3. From the wall box to the fireplace a 3-wire conductor with ground is recommended, however (2) two-wire conductors with grounds may be used in place of a 3-wire conductor with a ground if the black wires from the thermostat and blower switch are identified. 4. Two wall switches, or a wall switch and thermostat may be used to activate the two receptacle plugs independently. The intermittent pilot (120/24 volt system) is ON when the main burner is ON. When the main burner is OFF the intermittent pilot is OFF. The pilot flame should envelop 3/8 to 1/2 inch (10 to 13mm) of the tip of the flame rod. To adjust: 1. Remove the pilot adjustment cover screw. 2. Turn the inner adjustment screw clockwise to decrease or counterclockwise to increase pilot flame. Pilot adjustment is shipped at full flow rate. Turn the inner adjustment screw clockwise if the inlet pressure is too high. 3. Replace the cover screw after the adjustment to prevent gas leakage. Label all wires prior to disconnection when servicing controls. Wiring ...
