on ignition then yes, there may be a small quantity of unburnt gas. but ONLY on igniton.

I think there may be a viewing window on the front of your boiler.

You may be able to see a spark which lights a pilot and a second later the main burner lights.

If there is much of a delay at any point unburnt gas will be expelled from the flue.
