Field Controls 10 inch M+MG2 Barometric Draft Control

Field Controls 10 Draft Oil-Gas-Wood-Coal MGII-10 A double-acting control for gas-fired furnaces and boilers is widely used for conversion burner installations gas draft-induced appliance operation with mechanical draft inducers or sidewall power venters. It is also recommended for use on gas atmospheric appliances where a draft hood cannot be installed and can improve combustion stability and draft on many gas atmospheric installations with venting problems. The MGI provides precise accurate control of drafts at levels higher than permitted by a standard draft diverter which is a frequent requirement with gas. Because it is double-acting it opens out to relieve positive vent system pressures as low as .01. Draft adjustments using weights are simple and accurate from .01 to .1. Made in the USA.
