Hows it going fellas? Quick question for you.
Just went to service a Beckett AFG burner for the season. This is the fourth year I have serviced this unit, and I am fairly certain this was never a previous issue
When the burner de-energizes and winds down it still fires for a few seconds. There is no oil delay solenoid. It was my understanding there is a check valve in the pump to prevent flame on shutdown? Explain please?
I cleaned out the J-tube and the check valve in the nozzle adapter was free and clean.
Any info is appreciated.
