FIELD CONTROLS MG1- 4 Double Acting Draft Control

The FIELD CONTROLS MG1- 4 Double Acting Draft Control is a device designed to control the draft in a chimney or vent pipe. It is typically used in gas-fired appliances, such as furnaces and water heaters. The draft control helps to ensure that the appliance operates safely and efficiently by regulating the amount of air that is drawn into the combustion chamber.

The MG1- 4 Draft Control is a single-acting draft control, which means that it only opens when the draft in the chimney or vent pipe is too low. This helps to prevent the appliance from overheating and causing a fire. The draft control is also equipped with a gate stop, which prevents the gate from opening too far and allowing too much air into the combustion chamber.
