LP-GAS SYSTEMS --- SECTION 7 • 273

Each gallon of LP-Gas produces 91,502 BTU’s of heat. One 27 gallon tank
produces two million BTU’s. Total consumption depends on the rate of usage by
each appliance and the operating time. The stove and heating systems typically use
the most gas. With sub-freezing temperatures and high winds, consumption by the
furnace can be very high. Check the tank level often in cold weather.
Determine Fuel Consumption:
To determine approximately how many hours an LP-Gas appliance will operate
on one gallon of LP-Gas use the following formula:
• LP-Gas appliances are rated in Input BTU (British
Thermal Units). The rating is usually stamped or
printed on a tag affixed to the appliance. For example:
the Input rating of the appliance is 10,000 BTU's.
• One gallon of LP-Gas produces 91,502 BTU's.
• Divide the amount of BTU's of one gallon of LP-Gas
(91,502) by the rating on the appliance in this
example 10,000. Net continuous operation time for
one gallon of LP-Gas for this appliance would be
approximately 9.2 hours.
The above formula can be useful when trying to
determine the approximate length of time a tank of LP-Gas
will last. Generally, LP-Gas appliances do not operate
continuously. An example would be the typical cycling of
the furnace or water heater.
Determining how long a tank of LP-Gas will last:
• Combine the BTU input totals of all appliances and the approximate
length of time these appliances operate per day.
• Multiply the number of liquid gallons in the LP-Gas tank by 91,502.
• Divide the total of BTU's of the LP-Gas tank by the total number of
BTU's the appliances consume equals the approximate number of
hours of operation before refueling.
WARNING: LP-Gas is highly volatile and extremely explosive.
Never use matches or open flame to test for leaks. Use only
approved LP-Gas leak testing solution to test for leaks.
Unapproved solutions can damage copper tubing and brass fittings.
Never attempt to adjust LP-Gas regulators without the use of
proper equipment. Improper LP-Gas regulator adjustment will
affect the performance of LP-Gas operated appliances. Incorrect
flame or explosion can occur. Only qualified personnel should
perform any maintenance or repair to the LP-Gas system.
