Product Identity

The Field Controls 5RC is a barometric draft control designed for residential and commercial heating systems fired by oil, wood or coal. It is supplied as standard equipment on many leading appliance brands and arrives new in a silver finish.

Sustained Operation

The control is calibrated for easy adjustment to the furnace or boiler manufacturer's specifications across a range of .02" to .08". Its high sensitivity requires instrumentation during installation to ensure the draft remains stable under continuous firing conditions.

Questions about this item

Does the 5RC barometric draft control generate noticeable noise or heat when it operates continuously?

The 5RC is a passive mechanical damper with no motor or fan, so it produces no audible noise and adds no heat to the space during all-day operation.

What existing venting components must already be in place for the 46207201 to function?

A correctly sized chimney or flue serving an oil, wood or coal appliance is required; the control mounts in the breeching and relies on the existing draft to operate.

Will the 5RC work reliably alongside an older furnace or boiler that the buyer is keeping?

Yes, the control is calibrated for adjustment to the original equipment manufacturer's specifications and is designed for settings from .02" to .08", matching many legacy appliances.
