Description
The Viessmann 7875205 Ignition Cable transfers high-voltage energy from the igniter transformer to the burner electrode producing the spark required for fuel in the cylinder. It works through a 5k Ohm resistance path that directs electrical flow while limiting interference and energy fluctuation. In boiler-based HVAC systems such as gas-fired units and combi boilers, it is the electrical link between the thermostat assembly and burner section. Routed between components, it restores proper sequence and maintains steady burner operation.
