Step 11: Inspect the Photo Disc
1. If the photo disc is not free-floating, the electrode clamp bolt has been over-tightened, and has bent the electrode clamp.
Using a 10mm socket, remove the electrode clamp and re-straighten.
•
Lay the clamp’s beveled side down on a solid flat surface and align the thick end of the punch at dead center. Tap
the punch lightly until the retaining clamp returns to proper form.
Step 12: Reinstall the Diesel Burner
1. Align the diesel burner with the Aqua-Hot, using the alignment tabs welded on the Aqua-Hot.
2. Swing the eye-bolts around the “Ears” on the diesel burner and securely tighten, using a 10mm socket with a 10in long
extension.
NOTE:
When reinstalling the diesel burner, be careful not to damage the photo disc or bend the
electrodes. Also, be careful not to pinch any wires between the burner and the Aqua-Hot boiler tank.
Use extreme caution when tightening down the eye-bolt nuts� Over-tightening of the eye-
bolt nuts can cause the aluminum blower casing to crack�
