Type M+MG2
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. 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 smoke pipe,
specify our standard M+MG2 Draft Control, the unit that can be adapted to any fuel.
The moving part (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.
