The electronic ignition system in a gas furnace is a modern development that provides more reliable performance than a standing pilot system, offering energy savings through better furnace efficiency. There are two basic types of electronic ignition systems:. Understanding some of the basic components of a modern furnace will help you identify the type of furnace you have and narrow down the list of potential problems. Most furnaces with electronic ignition are either conventional induced draft furnaces or high-efficiency condensing furnaces. Induced draft furnaces use a small fan to draw the combustion gases from the combustion chamber and out of the house through the flue chimney. This system is more reliable and safer than old conventional furnaces, which relied on a natural draft coming in from an opening at the front of the furnace. Induced draft furnaces use either an intermittent pilot IP or hot surface ignition HSI instead of a standing pilot light. The combination of electronic ignition, electronic controls, and artificially created draft improves the efficiency of induced draft furnaces over older conventional models. Condensing furnaces use two heat exchangers, where conventional furnaces use only one.
