|
|
| |
| Problem with gas valve. | • Use a DC voltmeter to measure the voltage across the | |
|
| TPTH and TP terminals. Main operator voltage: Open | |
|
| circuit ≥ 325mV Closed circuit ≥ 100mV | |
|
| • If voltage is not present, check the control circuit for | |
|
| proper operation. | |
|
| • If proper control system voltage is present, replace the | |
|
| gas control. | |

|
|
| |
| Broken spark electrode. | • Check for broken ceramic insulation, replace electrode if | |
|
| broken. | |
|
|
| |
| Misaligned spark electrode. | • If spark is not arcing from electrode to pilot, loosen the | |
|
| screws on the pilot base adjust and tighten. | |

Pilot will not remain lit. | Problem with thermocouple | • Check for proper connection of the thermocouple to the | |
| circuit. | rear of the valve. If loose, fully tighten. | |
|
| • Check pilot for full flame impingement around | |
|
| thermocouple. If flame is too small, check gas pressure, | |
|
| adjust pilot rate screw, check pilot head for damage. | |
|
| • Check thermocouple voltage at valve. It must be greater | |
|
| than 5 mV. If low, replace thermocouple. | |

Burners will not remain lit. | Problem with thermopile | • Check gas line pressure . | |
| circuit. | • Check for flame impingement on thermopile. If low, see | |
|
| “Pilot will not remain lit”. | |
|
| • Check thermopile for minimum of 300 mV when burner is | |
|
| switched on. | |
|
| • Check wiring to thermostat for breaks. | |
|
|
| |
Flame lifting | Leak in vent pipe | • Check for leaks in vent connections. | |
|
|
| |
| Improper vent configuration | • Check vent configuration with manual. | |
|

| |
| Terminal may be recirculating | • Check to see if terminal is on correctly. | |
| flue gases | • May need to install high wind termination cap. | |
|
| • Contact dealer. | |

Glass fogs up | Normal Condition: after the appliance warms up the glass will clear. | ||
| **Due to additives in gas, glass may get hazy during operation** Clean as needed. | ||
|
|
| |
Blue Flames | Normal during start up: flames will yellow as the fireplace heats up. | ||
|
|
| |
Flames are burning “dirty” or | Flame impingement | • Check log positioning. | |
sooting |
| • Increase primary air by opening the venturi shutter and/ | |
|
| or by opening the vent restrictor. | |

Remote control doesn’t work | Problem with the remote | • One or more of the batteries are dead. See remote | |
|
| control instructions. | |
|
|
| |
| Problem with fireplace | • The on/off switch is turned to OFF. | |
|
| • The gas control valve is turned to PILOT or OFF. | |
|
| • The pilot has gone out. | |
