Fan does not "suck in gas", gas flows into the ignition chamber under pressure from the supply regulator.
My system mixes the gas and air before it goes into the ignition chamber (as opposed to being mixed in the chamber)(also has an inverted burner assembly i.e. top down))
I found this video on youtube of someone taking apart this sort of boiler
. Between roughly 12:00 and 15:00 he takes apart the air intake pipes. More intrincate than I imagined with several bends. I do wonder if that could be the cause although I would be surprised that a product out in the market (and for over a decade according to the guy) could have such a fault!
Old duffer you need to do some further reading. Pray tell how the oxypilot works.
Where did I say boiler uses oxypilot.
Clearly you explanation while has some merit it is devoid of practical functionality. I challenge you to apply a manometer to output side of a gas valve in a band A boiler and check if it indicated burner pressure at full power
