Gas Furnace Components 3 | HVAC Heating
Gas Furnace Components 3 - Gas furnace ignition controls vary from furnace manufacturer to furnace manufacturer. Some are proprietary and some are from an engineering company that specializes in gas furnace ignition controls. Honeywell being a major manufacturer of controls for HVAC also makes several gas furnace ignition controls.
Gas furnace ignition controls have advanced by leaps and bounds over the last 20 years. The standard was standing pilot ignition. Solid-state ignition controls are safer and more efficient than ignition controls of yesteryear.

Gas Furnace Components 2 - Gas Burners - Depending on the type of gas furnace and how the gas furnace was engineered will depend on the type of gas burners. Inshot burners generally shoot a flame into the combustion chamber where an induced draft exists. For sealed combustion chambers a forced or induced draft will exist.
Gas Furnace Components | HVAC Heating Systems. Different types of gas furnaces are available for purchase today and the older models which were installed many years ago still in operation. The older models were typically atmospheric-type gas furnaces and used a lot of gas to produce heat, much of which went up the flue because efficiencies were low.
