Gap at Boiler Flue - Potterton Suprima 50

[ShaunCorbs]

Boiler is directly below a small porch roof so I suspect the draught is coming from the roof and down the wall cavity. It wasn't an issue when the flue pipe was boxed in.

If wind can get in water can also just be mindful of this

Thanks. I'll keep an eye on it. I'm maybe overstating it as a 'draught'. Perhaps cold air from the external wall / roof is a better description. I wouldn't blow disturb a sheet of a4 for anything like that.

Just make up a removable boxing so that flue made accessible
