This is a series of compact, rugged, heavy-duty controls for use on large residential, commercial and industrial applications. The Field Type M+MG2 Draft Control provides precise draft regulators for solid fuels, oil, gas, or oil/gas appliances requiring only the simplest, on-the-job adjustments depending on which fuel is to be utilized. In a gas installation, the double-acting Type M+MG2 is specified instead of a draft hood to give the appliance the assistance of the chimney. In a duel fuel oil/gas or a gas-fired only application, use the M+MG2 as a double-acting draft control with the optional Field Thermal Switch accessory. Use the M+MG2 as a single-acting draft control for oil or solid fuel applications. For any installation with 10" or larger diameter vent pipe, specify our standard M+MG2 Draft Control, the unit that can be adapted to any fuel. The monving part (gate) rests on a long, thin, stainless steek knife edge which, in turn, is supported by self-aligning and self-cleaning bearings. When the heavy gauge gate moves, only the knife edge rests on the bearing for minimum friction and maximum sensitivity to draft changes.
