My gas boiler is situated in a purpose built room with a flue going up a chimney(sleeve inserted) . There is a small window in this room which is permanently open. The opening catch is screwed down to prevent it from being closed.....does this comply with current legislation please..?
it has been like this since beinging built some 30 yrs ago !!
