Hard to believe that such a simple device can do amazing things!įor more information on the Field Controls MG-1 or to order the double-acting barometric damper, visit the NCI store at /MG-1.Dampers prevent appliance over- firing due to excessĭraft. negated by the use of a barometric draft control located between the draft inducer or power venter. It can also maintain equipment efficiency when there is excessive draft. On sealed flues, such as on induced draft equipment, this also regulates combustion air to the burner. The same holds true if the flue becomes restricted or blocked. If the draft drops too low, flue gases will spill from the barometric damper and trip the safety switch. This controls combustion air to the burner allowing the supply of the proper amount of fuel by maintaining the outlet draft pressure. On drafthood-type equipment, it replaces the drafthood and connects equipment to the flue, rather than isolating the flue. This allows it to control venting and combustion air to equipment and maintain stable combustion. The MG-1 is sensitive to as little as a -.005-in. Its ability to relieve downdraft or positive pressure is beneficial because a safety spill switch can be added to turn off equipment if there is a downdraft, or more importantly if the flue is restricted or blocked. But the double-acting barometric damper is still helpful. Other than water heaters, there currently aren’t many standing pilot appliances. The original reason to relieve downdrafts was to prevent standing pilots from blowing out. The Field Controls Double-Acting Barometric Type MG-1 Damper differs from its single-acting cousin in that not only does it control updrafts, but it also relieves downdrafts.
