10" Barometric Draft Control

The Field Controls 1950201 is a 10-inch M+MG2 barometric draft control built for gas and oil appliances. It serves large residential, commercial and industrial installations that require precise draft regulation. The unit operates as a double-acting control for gas or dual-fuel setups and as a single-acting control for oil or solid fuel applications. Its gate rests on a stainless steel knife edge with self-aligning, self-cleaning bearings.

Vent diameter and fuel type

Verify that the vent pipe diameter is 10 inches or larger before ordering. Confirm the appliance fuel — gas, oil, solid fuel or a dual-fuel combination — to select the correct acting mode. Check whether a Field Thermal Switch accessory is required for the specific gas or dual-fuel installation. Ensure the mounting location allows the gate to move freely without obstruction.

Installation context and benefits

The control mounts directly in the vent connector or breeching of the appliance. It replaces a traditional draft hood on gas installations, allowing the chimney to assist draft performance. The self-cleaning bearing design reduces maintenance on the moving gate. The heavy-gauge gate and knife-edge pivot deliver stable operation across varying combustion conditions.

Questions about this item

Does the 10" M+MG2 Barometric Draft Control include the Field Thermal Switch accessory for gas installations?

The control is sold without the optional Field Thermal Switch, which must be purchased separately for double-acting operation on gas or dual-fuel systems.

When should I choose the 10" M+MG2 over a smaller draft control for my vent pipe?

Select the 10" M+MG2 when the installation uses a vent pipe of 10 inches or larger, as it is the standard size rated for that diameter and above.

How does the 10" M+MG2 maintain precise draft regulation once installed on a commercial boiler?

The gate rests on a stainless steel knife edge with self-aligning, self-cleaning bearings, allowing smooth movement and accurate draft control across solid fuel, oil, or gas appliances.
