Propane Systems - 7
propane conSumption
Each gallon of propane produces 91,502
BTU’s of heat. Total consumption depends on
the rate of usage by each appliance and the
operating time. The stove and heating systems
typically use the most propane. In sub-freezing
temperatures and high winds, propane
consumption by the furnace can be very high.
Check the tank level often in cold weather.
Determine Fuel Consumption:
To determine about how many hours a
propane appliance will operate on one gallon
of propane, use the following formula:
Propane appliances are rated in Input
BTU (British Thermal Units). The
rating is usually stamped or printed on
tag affixed to the appliance.
One gallon of propane produces 91,502
BTU’s.
Divide the amount of BTU’s of one
gallon of propane (91,502) by the
rating on the appliance.
This formula can be useful when trying to
determine the approximate length of time a
tank of propane will last. Generally, propane
appliances do not operate continuously. An
example would be the typical cycling of the
furnace or water heater.
Determining How Long a Tank of Propane
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 propane tank by 91,502.
Divide the total BTU’s of the propane
tank by the total number of BTU’s
the appliances consume. This equals
the approximate number in hours of
operation before refueling.
WARNING:
Propane is highly volatile and
extremely explosive. Never use
matches or open flame to test for
leaks. Use only approved propane
leak testing solution to test for leaks.
Unapproved solutions can damage
copper tubing and brass fittings. Never
attempt to adjust propane regulators
without the use of proper equipment.
Improper propane regulator
adjustment will affect the performance
of propane operated appliances.
Incorrect flame or explosion can occur.
Only qualified technicians should
perform any maintenance or repair to
the propane system.
propane Safety tipS
Propane is one of the safest and most reliable
fuels available on the market if handled
properly. Propane has a great explosive
potential if handled improperly. Danger is
minimized by becoming familiar with and
following a few safety precautions and by
learning how to properly operate propane
appliances.
Use of propane requires the responsibility to
enforce extra safety measures. The recreational
vehicle is equipped with many propane
operated appliances because it is a convenient
and efficient source of fuel. Propane
appliances must be operated and maintained
in accordance with the product manufacturer’s
instructions. The National Propane Gas
Association (NPGA) has a special service
program offered called GAS® (Gas Appliance
System) Check. The GAS® Check program
is aimed at educating users in the association
about the convenience of propane use with
safety and peace of mind.
For information on the
NPGA Gas® Check
program, call (202) 466-7200 or visit www.
npga.org.
Propane Tanks and Cylinders:
A steel
alloy two-piece welded and brazed tank is used
on all recreational vehicles. The marking on
the collar, DOT 4BA240, identifies the DOT
specifications and service pressure. Other
pertinent information included on the collar is
the water capacity (WC) and the tare weight
(TW), both of which are measured in pounds,
and the date of manufacture (one of the most
important items). There is a required 10 year
re-qualification. The final piece of information
is for the Dip Tube (DT) length. This is part
of the overfill protection and maximum liquid
allowance in the cylinder.
