The York S1-025 26361-700, 760-687 The spark igniter is a vital part of the gas furnace operation. This ignitor is made from ceramic and has the dimension of 3.6 x 5.35 x 2.55 inches and its function is to deliver high voltage shock to ignite the gas burner. Its function is to initiate combustion continuously and therefore provide warmth. When the thermostat of the furnace calls for heat, the ignitor gets a signal and produces a spark adjacent to the gas burner. This spark brings into action the gas, which in turn generates heat which is distributed to the entire house. The ceramic substance is rigid and does not melt at high temperatures.
