Field Controls 01804401 7 Inch MG1 Double Acting Barometric Draft Control for Gas

The Field Controls MG1 7-inch barometric draft control is a double-acting draft regulator designed specifically for gas-fired furnaces and boilers. This precision control device is widely used for conversion burner installations, gas appliances with mechanical draft inducers, and sidewall power venter applications.

Key Features:

• Double-acting design relieves positive vent system pressures as low as 0.01 inches water column
• Adjustable draft control using weights from 0.01" to 0.1" with simple, accurate settings
• Nominal capacity of 38.5 square inches for 6-7 inch pipe diameter applications
• Constructed from durable galvanized steel for long-lasting performance
• Fits pipes with 19 to 22 inch circumference
• Provides precise draft control at levels higher than standard draft diverters

This barometric draft control is recommended for gas atmospheric appliances where a draft hood cannot be installed. It improves combustion stability and helps resolve venting problems by allowing room temperature air to enter in the precise amount needed to overcome excess drafts caused by temperature variations, wind fluctuations, and barometric pressure changes. The result is more complete combustion, improved efficiency, and reduced maintenance requirements.
