Heater Component FunctionAir Proving SwitchSafety device used to insure that the proper air flow is beingachieved before the gas valve is opened.BurnerCast iron component used to channel gas and provide anarea at which the fuel may ignite.Burner OrificeBrass metering device used to feed gas to burner at aspecific rate.Direct Spark Ignition Control ModuleElectronic printed circuit board which sends and receivesvoltages to various controls in an automatic ignition system.An important safety feature of the control board is that it willshut down the entire heater, thereby stopping the flow offuel gas if burner flame goes out.Fan HousingChamber used for delivering air for efficient air movement.Fan WheelComponent used in conjunction with the motor and fanhousing to pull the hot air from heater and blow it into roomfor heating (also known as a squirrel cage).Gas Control ValveElectrical device consisting of a low pressure regulator andelectrical solenoids used for the control of gas flow to theburner assembly. A feature of the control valve is a built-ingas shut off which may be used to isolate the heater fromits gas supply when servicing.Gas HoseFlexible connector used to convey gas from supply line inbuilding to heater.Heat ChamberMetal “fire box” within the appliance that provides an areawhere burner flame mixes with combustion air, therebyproviding heat.High Limit SwitchSafety device wired into the control system which is used tobreak an electrical circuit to the gas control valve in event ofoverheat situation.IgniterIgnition device used on automatic direct spark ignitioncontrol systems. Ignites gas by spark.MotorElectric device used to force preheated air through theheater and to circulate heat within a certain area. Convertselectrical energy into mechanical energy.RegulatorMechanical device used in gas distribution systems toreduce a higher inlet pressure to a preset lower pressure.The regulator is responsible to supply a steady outletpressure to the heater(s) despite changes in inlet pressure,heater demand and weather conditions.Selector SwitchElectrical device which is used to allow the end user to usethe heater in either a heating or ventilation application.Status LightA green light emitting diode (L.E.D.) wired into the electricalcircuit. Provides an easily recognizable indication of heateroperation.ThermostatElectrical device used as an automatic “on/off” switchwhich will respond to changes in temperature in a certainarea. Can be wired so contacts in the thermostat open orclose on temperature increase or decrease.TransformerElectrical control used to accept line power supply primaryvoltage and reduce it to lower secondary voltage to operatecertain control systems.29
