I feel it needs to be made clear a few points regarding draughts which seems to be a concern to old school plumbers regrregarding flueless gas fires.
Unfortunately plumbers have NEVER been on a course that informs people about ''AIR FLOW''.
Too lazy to go on such a course or just too old to accept change ?
Draughts ? well- it is hard to pump air into a already filled up room . GOT IT ?.
Air only flows into a room that has the capacity to accommodate the new air .
Plumbers just cant figure that bit out.
CANT put 5 gallons into a tank/room that only holds 3 gallons.
No capacity for extra air- no draught.
I rest my case .
If that was true there would be no allowance for adventitious (google it) ventilation in the gas regs.
Any more CLUELESS gas fire ventilation tips?
