Hi .. So I have decided to get the vent fabricated rather than build it from brick or cast it.
Firstly is thin stainless steel appropriate? i.e the stuff used in residential homes for heating vents. If not what material should be used. I can get an HVAC guy to knock 1 up quickly and quite cheaply.
Secodly do I have to insulate it and cover it with render or can it be left "un insulated" as it will look quite nice. But thin metal and heat loss im not sure about.......
I have attached pictures of the build with a model of the vent and with out, for refference.
Also I have used the draw spread sheet and based on that I should be using 8 inch chimney pipe to get a good draw. However the oven is only 30 inch inside diameter. The opening is 18 inch wide and 12 inch tall... The vent opening is 10 inch deep. As per the photographs
Would 6 inch be better again Im thinking heat retention........... but is it better to go bigger diameter? Hope this all makes sense.
Any advice would be appreciated.
Thanks....
P.S sorry about the dog. He was inspecting the work done!
