A gas furnace is a home heating appliance that runs off of natural gas. The natural gas is burned in the furnace, warming up the air, which is then delivered throughout the home. when your home is cold thermostat tells the furnace to warm up the home. Then your thermostat sends its low-voltage command, a valve opens allowing the natural gas to begin flowing towards the burner. The blower then directs the incoming air from the ductwork towards the burner to start warming. In the next step, a pilot light lights the burner from inside the combustion chamber. This will allow the air to be heated up before it is transported back towards the ducts. The air would be pushed through a hot-air plenum this action protects those who are inside from any toxic fumes. All these steps will be repeated in a circle and keep you and your family warm and cozy.
