![]() ![]() The Type RC is calibrated to allow for easy adjustment to the furnace or boiler manufacturer’s specifications. The Field Type RC draft control is furnished as standard equipment on many leading brands of oil- or coal-fired heating equipment. We’ll help you keep the gases flowing, and keep the heat right where it needs to be. What does a calibrated draft control do Draft Control, Type RC. 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. Because every boiler is different, draft specifications will vary from unit to unit. Installation or operating conditions that produce excess amounts of draft can reduce the heating efficiency of the furnace. 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. This can cause inconsistent performance, and increased fuel costs. 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. Draft is the term for the difference in pressure between a boiler’s exhaust gases and the ambient air around the boiler stacks. /rebates/2ffield-controls-draft-control-283-n-capcty-5-to-7in-dia-6rc2fi2fG24706362f&.
