Remove upper shell (see page 8). 2. Remove fan (see page 13). 3. Remove fuel and air line hoses from nozzle assembly. 4. Turn nozzle assembly 1/4 turn to left and pull toward motor to remove. 5. Place plastic hex-body into vise and lightly tighten. 6. Carefully remove nozzle from the nozzle adapter using 5/8" socket wrench. 7. Blow compressed air thru face of nozzle. This will free any dirt in nozzle area. 8. Inspect nozzle seal for damage. 9. Replace nozzle into nozzle adapter until nozzle seats. Tighten 1/3 turn more using 5/8" socket wrench (4.5-5.1 n-m/ 40-45 inch-pounds). 10. Attach nozzle assembly to burner strap. 11. Attach fuel and airline hoses to nozzle assembly. 12. Replace fan (see page 13). 13. Replace fan guard and upper shell.

Remove upper shell (see page 8). 2. Remove filter end cover screws using 5/16" nut-driver. 3. Remove filter end cover and air filters. 4. Remove pump plate screws using 5/16" nut-driver. 5. Remove pump plate. 6. Remove rotor, insert, and blades. 7. Check for debris in pump. If debris is found, blow out with compressed air. 8. Install insert and rotor. 9. Check gap on rotor. Adjust to .076/.101 mm (.003"/.004") if needed (see Figure 27). Note: Rotate rotor one full turn to insure the gap is .076/.101 mm (.003"/.004") at tightest position. Adjust if needed. 10. Install blades, pump plate, air filters, and filter end cover. 11. Replace fan guard and upper shell. 12. Adjust pump pressure (see page 10). Note: If rotor is still binding, proceed as follows. 13. Perform steps 1 through 6 above. 14. Place fine grade sandpaper (600 grit) on flat surface. Sand rotor lightly in “figure 8” motion four times (see Figure 28). 15. Reinstall insert and rotor. 16. Perform steps 10 through 12 above. Figure 25 - Rotor Location, 35/70,000 Btu/Hr M...
