My build, New Zealand.

Looks great and access to the oven from the new door will make life easier.

Looking very nice Mark. You will need a double flue for the roof penetration. I did one years ago (sorry pics lost from a computer crash), where I just did the double flue from around 200mmm below the roof penetration point to the top of the flue where you need a cowl with a double flue seating, as well as an orange Dektite seal between the roof and outer pipe. This way you don't need the added expense of a full length outer pipe.

Hi David

I'm not roofing the part over the oven, for now! I may roof it later in which case I need to do a triple flue in terms of our building code. In the mean time, I need have 3x pipe diameters clearance between the flue and anything combustible, so the big hole works well.
