Field Controls 46220901 Control
As a seasoned tech, you know that consistent performance in oil and coal-fired systems depends on precise draft management. The Field Controls 46220901, also known as the Model 4" RC, is the industry standard for maintaining a stable barometric draft in residential and light commercial 4-inch flue applications. This single-acting barometric draft control is calibrated to counteract the negative effects of varying stack temperatures, wind fluctuations, and barometric changes that lead to fuel waste or incomplete combustion.
Designed for versatile installation, this 4-inch draft regulator features a sensitive gate that responds to pressure changes as slight as .02" to .08" w.c. By stabilizing the flue draft, the 46220901 prevents excessive heat loss through the chimney and protects against soot buildup and puff-backs in oil-fired heating equipment and coal stoves. The unit is typically installed in the vent connector, approximately 12 to 18 inches from the appliance. Using proper combustion testing instrumentation is critical during setup to ensure the gate is plumb and settings match the manufacturer's specific over-fire draft requirements.
Key Benefits for the Contractor:- Enhanced Combustion Efficiency: Maintains a steady air-to-fuel ratio, reducing fuel consumption in oil and coal units.
- Precise Draft Calibration: Adjustable weight system allows for fine-tuning between .02" and .08" water column.
- High Compatibility: Furnished as standard equipment for leading brands of oil-fired boilers and furnaces.
- Reduced Maintenance: Minimizes soot accumulation and prevents hazardous backdrafting or smoke spillage.
- Flexible Installation: Adaptable for vertical, horizontal, or sloping flue pipes with a secure collar fit.
When should I use a single-acting vs. double-acting control?
For oil and coal applications, a single-acting control like the 4" RC is required because it only swings inward to admit room air, preventing high-temperature flue gases from spilling back into the mechanical room.
Can this be used on a wood stove?
Yes, the RC series is suitable for oil, wood, or coal applications where a 4-inch flue is present and the draft needs to be held within the .02" to .08" w.c. range.
How do I know if the setting is correct?
Field adjustments should always be verified with a draft gauge. Set the control to maintain the lowest possible draft that still provides clean combustion and meets the appliance manufacturer’s specs.
