The pilot flame is/should be about 1.5" long, the diameter of a pencil. When the burners are going, the gas is shot into the burner manifold, and the gas sent to the burner is designed to go to the back of the heat exchanger. So, in a typical 80,000 input heater, about 14"-18" long.

How does a natural gas furnace work?
Natural gas furnaces work by combining natural gas with air and lighting it. This results in a flame that heats up the air and warms the rest of the house.
What is the difference between gas and natural gas and if your wall heater's pilot is too big maybe 8 how can you lower it to maybe 1?
In the United States their is only Natural Gas and Propane Gas. If you don't have a Propane Tank in your yard you have Natural Gas. If you have a propane gas furnace and want to change it to a Natural Gas furnace you have to have a heating/ac guy do it or you could burn your house down. The change in pilot size is directly proportional to the btu output of your furnace and is custom sized for each different make and model (1000's of different models in the US)
Is natural gas burning in a furnace a chemical change?
Yes, combustion of natural gas is a form of chemical change.
Where is the best place to get a Natural gas orifice for the change over from propane to natural gas on an Empire 65000 BTU floor furnace?
A supply house such as johnstone. Take all information of the furnace and old orifice with you and show them what you need.
Can you convert an oil burning furnace to natural gas furnace?
Yes, it is possible to convert an oil burning furnace to a natural gas furnace. This typically involves replacing certain components and making adjustments to ensure compatibility with the new fuel source. It is recommended to consult a professional HVAC technician for the conversion to ensure it is done safely and properly.
How does a natural gas furnace work?
Natural gas furnaces work by combining natural gas with air and lighting it. This results in a flame that heats up the air and warms the rest of the house.
How do gas furnace burners function to produce heat in a heating system?
Gas furnace burners function by mixing natural gas with air and igniting it to create a controlled flame. This flame heats up a heat exchanger, which then transfers the heat to the air that is circulated throughout the heating system.
What does a yellow flame indicate on a gas furnace?
its hot!
What is the function of a gas furnace flame sensor and how does it contribute to the proper operation of the heating system?
The function of a gas furnace flame sensor is to detect the presence of a flame in the furnace. It contributes to the proper operation of the heating system by ensuring that the gas valve remains open only when a flame is present, preventing the release of unburned gas and ensuring safe and efficient heating.
Why does the furnace igniter glow but no flame is produced?
The furnace igniter may glow but not produce a flame due to issues such as a clogged burner, a faulty gas valve, or a malfunctioning flame sensor. These problems can prevent the gas from igniting properly, leading to the lack of a flame.
What kind of fuel does a natural gas furnace need?
Natural gas.
How does a gas furnace pilot flame stay burning?
A gas furnace pilot flame stays burning by receiving a constant flow of gas from the pilot light assembly. The pilot light assembly contains a thermocouple that detects the presence of the pilot flame. If the flame goes out, the thermocouple signals the gas valve to shut off, preventing any gas leaks.
Seguence of operation for a direct ignition gas furnace?
If the furnace is direct ignition, The HSI or spark ignites the flame. A flame sensor passes current through the flame, if current is present the main.
Where is the furnace pilot located?
The gas furnace pilot (flame is lit all the time) 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. And when this little flame fails to operate properly or go out, it's one of the most common reasons a gas furnace will fail to operate.
How is fuel supplied to the pilot assembly on a gas furnace?
In a gas furnace, fuel is supplied to the pilot assembly through a gas line that connects to the gas valve. When the thermostat calls for heat, the gas valve opens, allowing gas to flow to the pilot assembly. The pilot, which is a small flame, ignites the gas, creating a flame that can then light the main burners when the furnace is operating. This process ensures that the furnace operates efficiently and safely.
what dose a yellow flame mean on a gas furnace?
Yellow flames from a natural gas furnace indicate that the combustion ratio is off and you have too much excess air in the mixture, if the discolored flame is isolated in the burner meaning on only 1 out of 3 or more then the burner/orifice may be out of alignment or there maybe a crack in the exchangers cell.
On a gas furnace what energizes the blower motor in heat mode?
flame sensor
