Propane is an efficient and versatile fuel. It belongs to the family of hydrocarbons. Propane is composed of hydrogen and carbon. It is actually a byproduct of crude oil or it is extracted with natural gas. An odor is added to propane so that it can be distinguished from other gases. It is pressurized into a liquid and stored in containers. It can be used as a liquid for engine fuel or as a vapor to heat your home, cook your food or heat your water.

Propane Tanks

All propane tanks are manufactured to safely contain liquid propane. Tanks are filled to within 20% of their maximum capacity. This allows room for vaporizing or expansion due to temperature changes. All propane fueled appliances burn propane vapor. All tanks are equipped with a percentage gauge, fill valve, shut off valve and a pressure relief valve. These are usually located under the hood of the tank. Tanks are leased by Polson Propane and will be maintained by the company.

Propane Regulators

Regulators are mandatory equipment on all propane installations. Regulators reduce tank pressure to the operating pressure of your appliances. Two regulators are used to insure maximum efficiency: one on the tank and another at the house. The first stage regulator is located on the tank and reduces the pressure to approximately ten pounds per square inch. The second stage regulator is located at the house and releases the propane at the appliance pressure. Regulators should be replaced every fifteen years or sooner if they become defective.
