Field Controls 00963801 Control

The Field Controls 00963801, designated as the Model 6"M, is a heavy-duty barometric draft control engineered for precision regulation in oil-fired boilers, wood stoves, and coal-burning applications. This 6-inch draft regulator maintains constant draft by compensating for changes in atmospheric pressure and stack temperature, ensuring optimal combustion efficiency and preventing excessive heat loss. Designed for high-stability performance, the gate is adjustable from .01" WC to .1" WC, allowing technicians to fine-tune the overfire draft to meet specific manufacturer requirements. Its rugged construction handles the high flue temperatures associated with solid fuel and oil combustion without warping. By stabilizing the chimney draft, this component prevents pilot outages and reduces soot buildup, which is critical for maintaining HVAC system reliability in demanding residential or light commercial settings. Proper installation of this draft stabilizer is essential for compliance with ventilation codes and maximizing the thermal efficiency of the appliance.

• Universal Compatibility: Specifically calibrated for oil, wood, or coal applications providing versatile flue pipe integration.
• Precision Calibration: Features a highly sensitive, balanced gate that responds to pressure changes as low as .01" water column.
• Enhanced Combustion: Minimizes fuel consumption by preventing excessive stack draft from pulling heat out of the heat exchanger.
• Durable Construction: Built to withstand commercial-grade thermal cycling and corrosive flue gases.

How do I set the draft for an oil-burning application?
Using a manometer, adjust the counterweight on the 6" M draft control until the readings match the appliance manufacturer's data plate, typically aiming for -.02" to -.04" WC at the breech.

Can this unit be installed in a vertical or horizontal position?
Yes, the Field Controls 6"M is designed for universal mounting, but the gate must be plumb and the adjustment weight must be properly indexed for the specific orientation.

What happens if the draft control is set too high?
An excessive draft setting will cause high stack temperatures and reduced efficiency, potentially leading to heat exchanger damage over time due to over-firing.
