4682CFI COMBO FLAME ROD/IGNITER ASSEMBLY The 4682CFI provides ignition and flame supervision for any 4682-3 through 4682-6 premix burner. They are ideal for open air spot heating applications like mold pre-heating, or molten Aluminum trough heating. When used with a 3070 inspirator mixer they can provide supervised emergency back-up furnace heating with very little electrical power. Because the igniter/flame rod is inside the nozzle feed pipe the electrode is protected from damage, and can be used with or without the optional tile. Mounting the electrode on the backplate keeps the ignition/flame rod cable away from the hot nozzle exit. An observation port is also included on the backplate. The 4682CFI works with any style air/gas pre-mixer including aspirator, inspirator, and premix blowers. It can be ordered as a standard assembly with a 4682 burner nozzle or can be part of a custom engineered solution for special applications. The 4682CFI can be used with the North American 8900-K Fire- Finder, which ignites and monitors the flame. It will also work with other spark and sense system.
