Inspect/correct flame rod/electrode
• Beforeinstallingtheburnerintheappliance,inspecttheamerodand
electrode.
• Verifythedimensionsshowninthispage.
• Iftheamerodorelectrodeisdamagedornotinthecorrectposition,
follow the procedure below to access and adjust.
To access the flame rod or electrode
1. If the burner is not installed in an appliance, you can inspect the flame
rod and electrode from the front of the burner. To change the position of
theamerodorelectrode,youmustremovethecombustionhead/gas
manifoldassemblyfromtheburner.See“D”thru“H”below.
2. To remove the combustion head/gas manifold assembly,you must
disconnect the gas piping and swing the burner flange door open. See
Figure 4, and proceed to:
a. Turn off all power to the burner and appliance before proceeding.
b. Close the manual gas valve on the gas supply line.
c. Disconnect the burner gas train union.
d. Remove the gas pipe at the burner air tube.
e. Remove the four nuts securing the burner hinged door flange.
f. Swing the burner open at the door flange.
g. Remove the two screws holding the gas manifold saddle to the air tube.
(Save the gasket.)
h. Disconnect electrode and flame rod wires then slide the burner combus-
tion head/gas manifold assembly out the end of the open air tube.
3. Position Electrode first — Make sure the electrode is placed according
tothedimensionsshowninFigure6.Toadjusttheelectrode,loosen
theelectrodeclampscrewandslide/rotateintoposition.
Tighten the electrode clamp screw after positioning. The shim rod

4. Position Flame rod after setting electrode — Make sure the flame rod
is located as shown in Figure 7. To adjust, loosen the flame rod clamp
screw. Tighten the screw to secure the flame rod in place.
5. Replacethecombustionhead/manifoldintheairtube.

sure the electrode is no closer
than 1/8” to any other metal
surface.
