Description
The Daikin-McQuay 059867701 Flame Rod is a flame safety part widely used in HVAC systems, especially in gas-fired furnaces and boilers. This flame sensor works under a principle called flame rectification in which it measures the electrical current of the flame ions. When the gas valve opens, the flame rod sends a small DC to show that combustion is taking place. In the case where no flame is sensed a few seconds, the system turns off the gas supply to avoid the risks of having a leak or a build-up of carbon monoxide. Some of the advantages associated with the use of this flame rod include safety, efficiency in the use of energy, and reduced dangers to the equipment.
