Feb 27, 2009 · A draft inducer motor pulls air through the combustion chamber and blows the exhaust up the flue. The air pressure switch "sees" the draft and gives the ignition device the ok to fire the burners. If it doesn't sense the draft at the beginning of the heating cycle, or loses it during the heating cycle, the unit locks out.
Aug 06, 2019 · They have their own advantage in the sense of operation, combustion, and ash handling, etc. But which topic today we discussed they also related to boiler operation.
