How do i light my wall furnace.

A pilot light going out can be inconvenient because it will completely cripple your furnace. Wall furnaces house a pilot light much like a water heater. An older gas furnace has a standing pilot that stays on all the time or at least it s supposed to. A gas furnace s standing pilot in which the flame is lit at all times is sometimes referred to as a pilot light but no matter what you call it its purpose is to serve as a small ignition flame for the gas burner when the thermostat signals for gas to be delivered from the gas valve to the burner it is the standing pilot that ignites the gas flowing to the burners to heat the air in the.

Since they have a pilot light system wall furnaces also can usually be repaired easily if something goes wrong. The gas may be the fuel but the pilot flame is the ignition and one that won t re light on its own. For better or worse a pilot light extinguishing isn t all that uncommon as even a light breeze or draft of air is enough to kill the tiny flame. They do require maintenance as well but are much easier to maintain by homeowners.

Many homeowners trying to fix a furnace for the first time are surprised if they don t find a traditional pilot light also known as a standing pilot. It s often expected that any appliance that burns natural gas or propane will include a tiny flame that constantly burns and ignites the gas when the appliance s controls deliver fuel to the main burners. Gas wall heaters whether vented or unvented can supply enough heat to warm a small or medium sized room and they can operate with propane or natural gas.
