Heatline 3003200909 air pressure switch

Description

Product Information: 
The air pressure switch facilitates safety protocols that check the fan is fully operational. It ensures that, if the fan fails within the boiler, there would not be a build-up of toxic gasses with no means of venting them. The PCB closely monitors the air pressure switch to make sure it is fully functional before the unit is fired up, preventing the appliance from starting without one of its key safety instruments.
