Alitude Map - Find my Altitude for Gas Heating
Use this tool to find out the altitude of your location. Simply enter your full address or zip code and hit search to find your elevation on the map.
Why do I need to know my elevation?
If you are installing a heater that used natural gas or propane you need to know your elevation. For any location up to 2,000 feet above sea level no modifications are needed. If you are installing a heater above 2,000 feet you should check with the manufactures recommendations to see if any modifications are needed to make your heater run correctly. The burner in a heater works by mixing fuel and air to create a mix for combustion. The higher in altitude you get, the less oxygen there is in the air. Since the proportion of fuel to air is now different, a change must be made. Usually, this means that a different orifice needs to be installed in the unit. A smaller orifice combined with the lower amount of oxygen will allow the heater to now work as intended.
Many units will also need to have changes made to their regulators or valves. Always consult the manufactures instructions as well as your local gas company to ensure proper instillation.
Keep in mind that not every product can work at every altitude. Many vent free heaters will not work at all in high altitudes. If you are not sure if a product will work for you, please contact us for more information.
