Oh doesn't know I am asking
We are putting up an awning/veranda roof and have a calor gas boiler . How close could we go to the outside vent and can anyone recommend a suitable heatproof material for the edges of the awning. He is not planning to go close to it but I would like it to be near it??

Your vent is located where. Extending out of the side wall?

Hi The vent is on the back wall to the right of the back door. The canopy will cover some of the back door and I would like to have it covering all of it but don't know how close we can go to the vent.
