The ignition and ionization electrodes should be replaced annually,
or more frequently if conditions require. Inspect the electrodes
periodically for signs of fouling, displacement, or other damage.
Electrodes should be replaced with the electrode turned towards the
burner mantle after it is inserted into the burner head. Observe the
dimensions below when replacing:
1/2" gap between ionization electrode and the surface of the burner
canister.
1/8" gap between ignitor electrode and ground electrode.
7/8" from ignitor electrode to the burner canister.
