Because this fireplace has an electronic ignition system, in the event there is a loss of power, it will be necessary to manually light the pilot with the piezo ignitor. After the pilot is lit, the main burner will light automatically.
1.Follow steps 1 through 3 under Nor- mal Lighting Instructions, page 21.
2.Set manual ignition bypass switch on control panel to ON position (manual ignition position). See Figure 52.
3.The pilot is attached to the rear of the front burner. You will be able to see the pilot and spark electrode without removing the screen or logs.
4.Place the magnetic manual override handle, provided with this unit, on the end of the gas valve stem (see Fig- ure 51).
5.Turn the override handle fully coun-
terclockwise 
to the PILOT po- sition. The handle will not stop but will begin to slip when you have fully turned to the PILOT position.
6.While holding the valve handle in the PILOT position, press and release piezo ignitor button (see Figure 52). This will light the pilot. If needed, keep pressing ignitor button until pi- lot lights.
7.When pilot flame is lit, hold manual override handle until thermocouple heats (approximately 5 to 15 sec- onds). If pilot goes out, repeat pro- cess. If several attempts to light the pilot fail, contact a qualified service person or gas supplier for repairs.
