incorrect wiring and correct or replace as necessary. Inspect
primary air openings (burner ports) for blockage, especially near
the pilot.
•
Visually check burner flame pattern when in operation. Flames
should be steady, not lifting or floating.

Test and measure the flame failure response time of the flame
safety system. It must de-energize the safety shutoff in no more
than (30) seconds.
