4-7
4.4 — Flame Loss Sequence
Remember, a safety device, for the most part, is doing its job when it shuts down or refuses to operate. Never
attempt to circumvent any of the safety features.
Preventive maintenance and scheduled inspection of all components should be followed. Periodic checking of the
relay is recommended to see that a safety lockout will occur under conditions of failure to ignite either pilot or main
flame, or from loss of flame.
