My boiler is a return flow scotch boiler. By the time the gas gets to the top of the chimney there’s a hell of a lot of gas between chimney and the burner. A big bang in the making!

Early on in this build I was warned against lighting at the flue like in that video.
My boiler is 5” in diameter. The end compartments are very thin stainless steel cans. They are lightly attached to the boiler ends  and not designed to resist or even experience pressure. If pressure does inadvertently occur its effect varies as the square of the boiler diameter. I’m not going to risk it.  It lights very easily at the burner end.
