Field Controls 02724001 6MG1 6" MG1 Barometric Draft Control For Gas hvac control

SKU CH-FN76-E50RV

Regulates draft in gas-fired furnaces and boilers with double-acting control from .01" to .1"

  • ColorSilver
  • Precise draft control from .01" to .1" with adjustable weights
  • Double-acting design relieves positive vent pressure as low as .01
  • Improves combustion stability on gas atmospheric installations with venting problems
  • Suitable where a draft hood cannot be installed on gas appliances
  • Widely used for conversion burners and mechanical draft inducer systems

What it is

The Field Controls 02724001 6MG1 is a double-acting barometric draft control built for gas-fired furnaces and boilers. It suits installers working on conversion burners, draft-induced appliances with mechanical inducers or sidewall power venters where a draft hood cannot be fitted.

How it fits

The unit mounts in a six-inch vent connector and replaces a standard draft diverter when tighter regulation is required. It relieves positive vent pressures as low as 0.01 inches water column and allows weight-based adjustment from 0.01 to 0.1 inches, freeing the appliance from over-fire pressure swings.

Under sustained load

Because it responds to both negative and positive pressure, the control maintains stable draft through continuous firing cycles without hunting. The mechanical weight system holds its setting over long heating seasons, keeping combustion consistent when vent conditions vary.

Questions about this item

What is the lowest positive vent pressure the 6MG1 can relieve?

The double-acting design opens out to relieve positive vent system pressures as low as 0.01 inches of water column.

How much heat does the barometric draft control generate during continuous operation?

The control is a passive mechanical device with no motor or electrical components, so it produces no measurable heat while regulating draft.

Which gas-fired appliance must already be installed for the 6MG1 to function?

It is designed for gas-fired furnaces, boilers, conversion burners, draft-induced appliances with mechanical inducers, or sidewall power venters.
