Light-off Problems
The distance between the flame rod and the burner (mantle) should
be 3/8”. The dimensions on both the booster ignitors and the flame
rod are not easily adjustable - bending the rods can cause damage
to the insulation material. In addition, a bent electrode will return
to its original shape when heated. If an electrode or flame rod is out
of specification, replacement is generally required. Clean or replace
as necessary.
Also see Troubleshooting Char t below.
Electrode spacing for the booster ignitor should be 1/8”.
The distance of the nearest booster ignitor electrode to the mantle
is approximately 7/8”.
