stop being a knob! the aps is a safety device which should not be linked out it tells the boiler that it is safe to fire as the fan is running to expel the fumes. Its against all regs and law

you irrryit!

you shouldnt link an aps out as it parts of the flue system this is designed to tell the boiler that the fan is running at the correct speed to give enough pressure to remove products of combustion which will then allow the boiler to ignite. u should check the venturi first before replacing the aps. what boiler is it model???
