Product Identity

The Field Controls 963801 is a 6M barometric draft control built for residential oil, wood and coal heating systems. It provides precise draft regulation through an infinitely variable screw adjustment that allows extremely fine instrument settings.

Ideal Users and Limits

This control suits installers and homeowners who need stable, accurate draft management in the 0.01 to 0.1 range for solid-fuel or oil appliances. It is not suited for systems that require automated electronic modulation or for installations where a larger diameter connection is specified.

Installation Checks

Verify that the appliance flue accepts a six-inch male connection and that the mounting orientation matches the gate curvature design for horizontal or vertical runs. Confirm the draft range required by the appliance falls within the control’s adjustable span before fitting.
