Refer to our Contractor Reference Guide on when to use a draft control with a draft inducer/power venter, power burners, forced draft burners, dual fuel appliances and gas-fired appliances. The unit operates more efficiently, reliably, and requires less maintenance. The velocity of combustion gases through the heat exchanger is slowed so more heat is extracted.
a graduation that is calibrated with regard to force and lifting height. In general the draft regulator is set to the.
It is calibrated to allow for easy adjustment to the furnace or boiler manufacturers specifications. The RC Draft control is furnished as standard equipment on many leading brands of oil or coal-fired heating equipment. Combustion of fuel is complete and the process is stabilized.

The pressure difference between the room air and heated gas (air) causes products of combustion to flow (draft) through the unit and rise through the breach and chimney. FIELD CONTROLS Barometric Draft Control: 6 in to 8 in, Galvanized Steel, 38.5 Nominal Capacity. How do draft controls work? Static pressure of the cool air exerts pressure on the outside of the furnace or boiler, the breaching, and stack. 08″, this control is so sensitive that instrumentation should be used when adjusting the unit during installation.
