Install new ignitor. Attach ignitor to rearhead with ignitor mounting screw.6. Run ignitor wire from new ignitor throughnotch in filler panel. Attach ignitor wire topiezo ignitor.7. Set gap between ignitor electrode and targetplate to 0.17" (43.18 cm) (see Figure 12).WARNING: Make sure heateris disconnected from propanesupply. Heater could ignite caus-ing severe burns.8. Test for spark. Push piezo ignitor buttonand watch for spark between ignitor elec-trode and target plate.9. Place motor and fan guard into rear ofheater shell (see Motor, page 8, steps 9and 10).SerVICe PrOCeDureSContinued
