How To Adjust Propane Heater For High Altitude?

Do propane heaters work at high altitude?

But how do propane heaters fare in high altitudes? LP heaters that are vented work well at high altitudes, while their vent-free counterparts may not function over 7,500 feet. This is because there is not enough oxygen in the air to run them continuously.

How do you derate a gas furnace for higher elevations?

This typically involves a manual adjustment of the furnace’s valve outlet. Most furnaces need to be derated by 4 percent for every 1,000 feet above sea level (but check your manual or consult with a heating professional to be sure).

How does altitude affect the firing rate of a furnace?

How does altitude affect the firing rate of a furnace? Higher altitudes have lower firing rates. The number of times the gas dial rotates in a minute and the gas heating capacity are used to calculate the firing rate.
