Are Barometric Draft Controls Used on Gas-Fired Equipment?
Incidentally, draft controls might be found on gas-fired heating equipment too, but the specifications are quite different. Gas fired heaters such as domestic gas fired furnaces are usually designed to operate at very low over-fire drafts – which means almost zero draft will be measured at the flue vent connections. That’s why you usually don’t see a hinged-door barometric draft regulator on gas fired equipment. Take a look at DRAFT HOODS – gas fired for details. Field Corporation, and surely other draft regulator producers, provides different model draft controls for gas fired equipment, such as the Field Type MG1 and MG + MG2 regulators which use double swinging gates that open inward under normal up-draft conditions and outward in case of blocked flues, thus relieving internal pressures. Since improper venting of gas fired appliances easily produces very dangerous, potentially fatal Carbon Monoxide (CO), it is critical that these appliances are vented properly. Do not ever install a
