BURNER ASSEMBLY & SPARK ROD ALIGNMENT

The spark rod MUST NOT be parallel with the pilot (Figure 3-70), the rod tip should tilt towards
the pilot head with an 1/8” (eighth of an inch) gap (Figure 3-71). The spark must occur forward
of the pilot buttery outlet, where the gas and air are mixed to ensure consistent pilot lighting.
