Hi Canal World,
Yet another question about heating, this time the collar for the flue pipe. Installing in a widebeam at the side, Its in a corner next to an internal bulkhead.
The roof angle is, as some might expect, different from the angle built-in to the collar. So where the flue attach's to inside collar, and chimney outside, it doesn't provide an upright/vertical fitting for the flue.
Is it acceptable to make something for the collar on the outside roof off the boat (packing) causing the collar to be upright, it would mean raising one side apprx 26mm (guessing there may not be enough tube to attach flue to on the inside though)
Or is it ok for the chimney to be at a slight angle, and of course the flue to be at an angle...it would be square to the collar! I can cut and weld the flue so it meets the collar square but someone suggested you will need to install 2 angles on the flue...but I can happily do it with one angle.
So is one angle in the flue a concern, or is it a concern that the chimney would sit on the roof collar at a slight angle, apprx 7 degrees so not far from upright.
Cheers
