Hi was wondering if anyone could help me, I was at job today and there are two of the exact same fires in living room and dining room that has been made into one room as the wall has been knocked down to make it one big room. Both fires are under 7 kw, both have passed safety checks. I have spoke to gas safe who advised that adventitious can be taken off for one fire but a vent would have to be put in for other one. I have done a bit of research tonight and it seems quite conflicting as to whether I will need vent or not, any help would be appreciated
