Important Information! | Premix Gas Burner Nozzles
DO NOT attempt to remove electrode body from a "4682CFIB" burner before reading instructions.
The 4682CFIB electrode body cannot be removed from the burn- er without following the instructions below (due to interference between the electrode tip and the burner nozzle and insulator). To replace the electrode tip or electrode body for maintenance, first loosen the set screw on the Electrode Coupling by inserting a hex key through the premix inlet Once the setscrew is loosened the electrode tip can be removed by pulling it out from the 4682 nozzle, or the electrode body can be unscrewed and removed.
When the electrode body and coupling are reinstalled the cou- pling setscrew can be re-aligned with the opening in the pipe tee by loosening the electrode nut to allow the insulator to be rotated until the set screw aligns with the inlet opening. SETTING THE ELECTRODE LENGTH AND SPARK GAP When repositioning the electrode tip, set the distance from the burner nozzle using the dimensions below. The tip should be set so it is between two of the holes in the outside row of premix holes as shown below. Re-tighten the setscrew once the electrode tip is in the correct location.
