HBDV7 Series Direct Vent Gas Fireplace | TROUBLESHOOTING | ||
Standing Pilot Ignition |
| ||
SYMPTOM | POSSIBLE CAUSE | ACTION | |
|
|
|
|
1. | Spark ignitor will | A. Wire disconnected. | A. Open door and check to make sure wire is connected |
| not light pilot after |
| to ignitor. |
| repeated triggering of | B. Defective ignitor. | B. Check for spark at electrode and pilot. If no spark and |
| piezo. |
| electrode wire is properly connected, replace pilot |
|
|
| assembly. |
|
| C. No gas or low gas pres- | C. Check remote/manual shut off valve from fireplace. |
|
| sure. | Low pressure can be caused by bent lines, restricted |
|
|
| lines, low pressure line pressure. Consult with plumber |
|
|
| or gas supplier. |
|
| D. No Propane/LPG in tank | D. Check Propane/LPG tank. Refill tank. |
|
|
| |
2. Pilot will not stay lit | A. Defective thermocouple | A. Check that thermocouple flame impinges on thermo- | |
| after carefully follow- |
| couple. Clean and/or adjust pilot for maximum flame |
| ing lighting instruc- |
| impingement. Ensure that the thermocouple connec- |
| tions. |
| tion at the gas valve is fully inserted and tight. |
|
|
| Disconnect the thermocouple from the valve, place |
|
|
| one millivolt lead wire on the tip of the thermocouple |
|
|
| and the other meter lead wire on the thermocouple |
|
|
| copper lead. Start the pilot and hold the valve knob in. |
|
|
| If the millivolt reading is less than 15 mV, replace pilot |
|
|
| assembly. |
|
| B. Defective valve | B. If thermocouple is producing more than 15 mV, |
|
|
| replace faulty valve. |
|
|
|
|
3. | Pilot burning, valve | A. Defective switch, wall | A. Check switch and wire for proper connection. Place |
| knob turned to “ON”, | switch, remote control or | jumper wires across terminals of switch. If burner |
| switch is turned to | wire | comes on, replace defective switch.If the switch is OK, |
| “ON” or “RS”, but |
| repeat the same procedure on remote control If burner |
| burner will not ignite. |
| comes on, replace remote control. |
|
|
| Place jumper wire across wire at gas valves (terminals |
|
|
| marked TH and TP/TH). If burner comes on, wires are |
|
|
| faulty or connections are bad. Replace wire. |
|
| B. Pilot flame too small | B. If pilot flame is not close enough to the thermopile, |
|
|
| adjust pilot flame. |
|
| C. Defective or malfunction- | C. Check thermopile wire connections to make sure |
|
| ing thermopile | all are tight and that the thermopile is fully inserted |
|
|
| into pilot assembly. Check thermopile with a millivolt |
|
|
| meter. Connect leads to TP and TP/TH terminals on |
|
|
| the control valve. If meter reading is below 325 mV, |
|
|
| replace pilot assembly. |
|
| D. Defective valve | D. Turn valve knob to “On” and switch to “ON.” Take a |
reading at the thermopile leads (TP & TP/TH) on the valve. If the meter reads greater than 175 mV and the burner does not light, replace defective valve.
