Propane
Propane is a three-carbon alkane with the molecular formula C₃H₈. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel. Propane is one of a group of lique…

What happens if furnace gas pressure is too low?
If the gas pressure is too low, your furnace's efficiency will go down. Not only that, but it will lead to a greater amount of condensation of burned gases. That is because the proportion of air in the air-fuel mixture will be too great.
