M+MG2  DRAFT CONTROLS


TYPE M+MG2 DRAFT CONTROL

SOLID, OIL OR GAS COMMERCIAL/INDUSTRIAL

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 regulations 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. For oil/gas, the M+MG2 Double-Acting with a Field Thermal Switch. For oil or solid fuel, the Type M+MG2, Single Acting. For any installation with 10" or larger diameter smoke pipe, specify our standard M+MG2 Draft Control, the unit that can be adapted to any fuel. The moving part (or gate) rests on a long, thin, stainless steel 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.
