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 Mg-1 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″.
