A) Check ignitor wire. Tighten or reattach loose ignitor wire. See Figure 13, page 13 for ignitor wire location. B) Set gap between ignitor electrode and target plate to .17". C) Tighten nut holding piezo ignitor to base of heater. D) Replace ignitor electrode. See Ignitor, page 13. This can happen when running heater in temperatures above 85°F. Run heater in cooler temperatures. Check heater inlet and outlet. Remove any obstructions. Replace fan. See Fan, page 12. Clean heater. See Maintenance, page 9. ! WARNING Use only in areas free of high dust content. 10 ! W ARNING Never service heater while it is plugged in, connected to propane supply, operating, or hot. Severe burns and elec- trical shock can occur. ! W ARNING Never service heater while it is plugged in, connected to propane supply, operating, or hot. Severe burns and elec- trical shock can occur. SERVICE PROCEDURES Motor 1. Access ground screw through underside of heater base. Remove ground screw. Disconnect the green motor wire and the green power cord wire from underside of shell (see Figure 6). 2. Remove black and white motor wires from terminal board (see Figure 6). 3. Remove two wire guard screws. Remove wire guard. 4. Set heater on its base. Remove three screws that Figure 6 - Location of Ground Screw and Wire Guard attach fan guard to heater shell (see Figure 7). 5. Remove motor and fan guard from heater shell. Carefully pull the green, black, and white motor wires from hole in shell (see Figure 7). 6. Use pliers to remove the fan nut from front of motor shaft (see Figure 8). 7. Remove fan. Be careful not to damage the fan blade pitch. 8. Use nut driver to remove three nuts that attach fan guard to motor. Remove Figure 7 - Removing Motor and Fan Guard from Heater fan guard from motor (see Figure 9). 9. Discard old motor.

Attach fan guard to new motor with three nuts. Tighten nuts firmly. 11. Place fan onto motor shaft of new motor. IMPORTANT:When placing fan onto motor shaft, make sure part number stamped on fan is facing motor. Attach fan nut to end of motor shaft. Tighten fan nut firmly. 12. Place motor and fan guard into rear of heater shell. Carefully route motor wires through hole in shell (see Figure 10). 13. Insert three screws through heater shell and into fan guard. Tighten screws firmly. 14. Turn heater on its side to access opening in bottom of base. Connect green motor wire and green power cord wire to heater shell using ground nut (see Figure 6, page 11). 15. Attach black and white wires to empty connectors on black and white wire sides of terminal board. 16. Attach wire guard to shell with two screws (see Figure 6, page 11). Fan 1. Remove fan and motor (see Motor, page 11, steps 1 through 6. 2a. If replacing fan, remove old fan and discard. Go to step 5 below. 2b. If cleaning fan, remove fan. Be careful not to damage the fan blade pitch. 3. Clean fan using soft cloth moistened with kerosene or solvent. 4. Dry fan thoroughly. 5. To replace fan, follow steps 11 through 16 above. Hole in Shell for Motor Wires Figure 10 - Replacing Motor and Fan Guard into Heater 12 Ignitor 1. Remove motor and fan guard from heater (see Motor, page 11, steps 1 through 5). 2. Remove black ignitor wire from piezo ignitor. Access ignitor wire through underside of heater base (see Figure 11). Push wire up through bushing in heater shell. 3. Remove ignitor mounting screw from rear head using nut-driver or standard screwdriver (see Figure 12). 4. Remove ignitor from rear head. 5. Install new ignitor. Attach ignitor to rear head with ignitor mounting screw. 6. Run ignitor wire from new ignitor through bushing in heater shell. Attach ignitor wire to piezo ignitor. 7. Set gap between ignitor electrode and target plate to .17" (see Figure 13). 8. Test for spark. WARNING: Make sure heater is disconnected from propane supply. Heater could ignite causing severe burns. Push piezo ignitor button and watch for spark between ignitor electrode and target plate. 9. Place motor and fan guard into rear of heater shell (see Motor, page 12, steps 12 through 16).
