ports. Verify that there is no ignition delay. Inspect and
ensure the lighting of the main burner occurs within four
seconds of the main gas valve opening.

size is correct. See Service Parts List for proper orifice
sizing.

pipes and other components for leaks.
• Inspect pilot flame pattern and strength. See Figure 4.6
for proper pilot flame pattern. Clean or replace orifice
spud as necessary.
