I have a 9kw basket type gas fire and have 100 sq centimetre air vent fitted to outside wall. The problem I have is that I want to have a new porch built which will cover up the air vent, would it be ok to have the same size air vent built in to the porch so there is a continous stream of air flowing from the lounge to the outside ?
many thanks in advance for your advice.
Mike
