In addition, the boiler may not work due to a malfunction of the draft sensor. If after the first ignition of the Conord gas boiler, the flame goes out, and the second attempt also fails, it is worth checking the sensor and shorting the terminals together. And only if this does not help, a traction sensor may need to be replaced.Get Price
This is achieved by modulating the draft damper in response to the deviation between the measured draft and an operator adjusted set point. Draft Control is typically used in systems where multiple boilers share a common stack and outlet ductwork, or in a single boiler application with high natural draft. B.

Working Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion.Get Price

Operation. An electronic sensor is inserted into the boiler flue, near the boiler, ahead of any dampers or other sources of air leakage into the boiler or flue. The sensor is connected to a control panel that measures oxygen and sends a signal to a control damper on the burner air supply. From the Hays Cleveland OXY-MIZER™ data sheetGet Price
