WARE has the skill and expertise to install, service, and optimize barometric draft controllers for any boiler system. It’s a simple, reliable way to create the best draft for your boiler based on the conditions around you. However, adding small weights to the actuating lever of the butterfly valve allows the valve position to be precisely adjusted to create the desired draft. The valve itself is unevenly weighted, and will try to stay fully open. However, once you know the ideal draft for a burner, the barometric draft control can be fine-tuned to preserve ideal firing conditions.īarometric dampers operate by opening and closing a butterfly valve in the stacks to restrict or increase the flow of exhaust gases.
Field Controls Draft Control 7RC with collar 7' RC for oil or coal-fired furnace or boiler heating equipment. Field Controls 02723101 7RC Draft Control. Because every boiler is different, draft specifications will vary from unit to unit. It is calibrated to allow for easy adjustment to the furnace or boiler manufacturers specifications. However, there is a simple, intuitive way to keep the pressure in the stacks negative, and keep exhaust gases flowing at the ideal rate.īarometric draft controls, also called barometric dampers, help maintain consistent airflow through the stacks to maintain the ideal level of negative pressure the burner requires.

ADDITIONAL APPLICATIONS (FOR RC SERIES DRAFT CONTROLS). This can cause inconsistent performance, and increased fuel costs. calibrated to allow for easy adjustment to the furnace or boiler manufacturers specifications. If there’s too much back pressure, exhaust gases won’t be able to escape and the boiler won’t be able to fire efficiently. Ideally, draft should be slightly negative to draw the exhaust away from the boiler and prevent back pressure from developing. BAROMETRIC DRAFT CONTROLS WITH OR WITHOUT COLLAR The Field RC is furnished as standard equipment on many leading brands of oil fired heating equipment. Draft is the term for the difference in pressure between a boiler’s exhaust gases and the ambient air around the boiler stacks.
