Highlights of the M+MG2 Commercial Draft Control for Oil, Gas, and Solid Fuel

  • SAFE: Maintains the boiler’s draft to burn fuel more efficiently
  • EASY INSTALLATION: Collar included to ensure a safe, snug fit
  • EFFICIENT: Adjust air flow rate to produce a steady, safe, and efficient flame without the risk of backdrafting
Features of the M+MG2 Commercial Draft Controls

The Type M+MG2 Commercial Draft Control models are a series of compact, rugged, heavy-duty controls for use on large residential, commercial and industrial applications. The M+MG2 Draft Control provides precise draft regulators for solid fuels, oil, gas, or appliances requiring only the simplest, on-the-job adjustments depending on which fuel is to be utilized.

Installation Options

In a gas installation, the 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 the Field Controls standard M+MG2 Draft Control. This 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.

How it Works

How do draft controls work? Static pressure of the cool air exerts pressure on the outside of the furnace or boiler, the breaching, and stack. The pressure difference between the room air and heated gas (air) causes products of combustion to flow (draft) through the unit and rise through the breach and chimney. Room temperature air enters through the barometric draft control in the precise amount needed to overcome the excess drafts caused by temperature variations, wind fluctuations, and barometric pressure changes. Combustion of fuel is complete and the process is stabilized. The velocity of combustion gases through the heat exchanger is slowed so more heat is extracted. The unit operates more efficiently, reliably, and requires less maintenance.

When to use a draft control? Refer to our Contractor Reference Guide on when to use a draft control with a draft inducer/power venter, power burners, forced draft burners, dual fuel appliances and gas-fired appliances.

The M+MG2 Commercial Draft Controls should be installed by a licensed contractor. Find a contractor in your area.
