The arc from the electrode tip should jump from tip to the body of the pilot housing and should be lined with the
hole in the backside of pilot housing, so that the blower air passing throught this hole will cause the arc to "FLAG"
(or move around). Normal spark gap should be 1/16" – 3/32". The electrode should not be moved so far forward that
the pilot fl ame will impinge on the porcelain insulator. This may cause damage to the porcelain. See the drawings for
the pilot assembly for the C-Burner.

Pilot Case to Gas Manifold Adjustment
Pilot Assembly–C-Burner For C3, C4, & C5 Burner
Pilot case to gas manifold adjustment is
very important. As depicted, the inside
radius of the pilot body must be tight
against the outside radius of the gas
manifold.
The bottom of the pilot body must also
be tight against the notched portion
of the baffl e ring, just slightly above
the scanner pipe. If there is an air gap
between the pilot body and the gas
manifold and/or the baffle ring, the
resulting air fl ow may prevent the pilot
flame from being swept downward
across the scanner pipe.
