The ignition electrode is used to create a spark to automatically ignite the gas and is activated by the controller. It also lets the controller know if a flame is
present.
IMPORTANT:
For reliable operation it is important to install the electrode properly!
We have provided an electrode that can easily be modified (cut and/or bent) to fit nearly all burners. If you are installing in the current version of the
Blichmann Engineering™ HellFire™ burner simply use the flame inspection hole as shown in Figure 5 for installation. For other burners, you will need to drill
two holes to fasten and ground the electrode to the burner frame. Place two marks 3/8” (10mm) apart and about 1 inch above the surface of the burner.
Strike both marks with a center punch. Drill one at 3/8” and the other at 3/16”. Typical installations are shown in fig 4 and 5.
TIP:
Stainless steel can be challenging to drill – use a cobalt or TiN coated (gold color) bit to drill the 3/16” hole.
Mark the electrode wire with a marker so that when bent 90 deg downward it will be in the center of the flame path. For HellFire™ burners, you’ll want the
electrode centered over one of the burner nozzles. Measure the distance from the surface of the burner to the mark on the wire and note this distance.
Remove the electrode from the frame and using a pliers bend the wire down 90 deg. Install with the included #8-32 X 3/8” screw.
IMPORTANT:
The tip of the electrode must be perpendicular to the surface of the burner and must be in the flame path to function properly! A spark gap of
3/16-1/4” (5-6mm) is needed for consistent ignition.
CAUTION:
Do not hold the electrode by the ceramic insulator and take care not to crack the insulator! Cracked electrodes are not covered under warranty!
Trim the wire using a wire cutter to the length noted previously. Install the electrode and note the position of the tip of the wire with respect to the surface
of the burner. Trim as needed to provide a 3/16-1/4” gap. It is OK to bend the wire a bit as needed to center the tip of the electrode. Figure 4 and 5 show
typical installations.
