ash pans
My ash pan is airtight and the engine will give off white vapour when shut, by airtight i mean any gaps at all sealed. that air tight the fire would go out if the damper was left shut and when pulling hard you struggle to open it or prehaps i go around priming all the time aswell.look through your firehole door with no fire on the grate damper shut then you will see how airtight your ashpan is if you see no light......
