4. Apply belleville washers so that they crown in middle; do not use nuts or
washers that are not provided by Fulton.
5. Apply anti-seize to burner ange studs and torque to 23 ft-lbs. A torque
adaptor will be required and should be used at 90° from the wrench
handle.
6. Torque nuts under the premix elbow to 19 ft-lbs.
7. Reinstall ignitor or new ignitor. See verication of ignition gap for
instructions.
8. Ensure door and all latches are closed when complete. The louvers in
the door provide cooling air to the electrical panel. The door must be
completely closed to prevent unltered air leaking into the cabinet.
Verification of Ignition Gap
NOTE: Fulton recommends annual replacement of the ignition electrode
assembly: EDR-750/1000 part number 5-20-071003 (all burners). EDR-1500/2000
part number 5-20-072000 (metal woven mesh burners only).
1. Remove ignition electrode assembly (ignitor). Visually check that the
insulators are clean.
2. For re-installation or installation of a new ignitor, verify with calibrated
calipers that there is a gap between electrodes greater than 0.100” (2.54
mm) and less than 0.125” (3.175 mm). See Figure 76.
3. Install the ignitor on the burner ange: Apply anti-seize compound to
ignitor screws and tighten in place using a torque-rated screwdriver to 8
inch-pounds. Use only a new gasket assembly, Fulton Part Number 2-12-
001261.
4. Remove the sight glass, ame scanner, and heat block. Position a light to
shine into the combustion chamber through the sight glass as required.
