BS6173 says…

“It is important to make sure all natural and mechanical ventilation systems are working effectively. The installer should have fitted the appropriate interlocking system between any mechanical ventilation system and the operation of gas appliances so that failure of the system causes the gas supply to them to be shut off. Installation of manual bypasses to such interlock

systems is not permitted.”
