276 | Section 7 LP-Gas System ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ----------------- Monarch SE 2004
Liquid Propane gas is one of the safest and most reliable fuels available on the
market if it is handled properly. LP-Gas, however, does have 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
LP-Gas appliances. Use of LP-Gas requires the responsibility to enforce extra
safety measures.
The motorhome is equipped with many LP-Gas operated appliances because it
is a convenient and efficient source of fuel. LP-Gas 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 the 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 (630) 515-0600 or visit www.npga.org.
LP-Gas Tanks and Cylinders:
Tanks are built to American Society of Mechanical Engineers (AMSE) Code.
The cylinders are built to DOT (Department of Transportation) Code. The major
difference between cylinders and tanks is in required testing and inspection
procedures and in the construction of the containers. Both tanks and cylinders are
required to undergo pressure testing and inspections; however, the procedures for
how they are tested and inspected differ.
The difference between the two codes are that the valves, fittings and brackets
are located only on the ends of the DOT cylinders; however, on the ASME tanks
they may be located on ends, as well as the sides. There is also a difference in how
the tanks are rated. Required tank ratings are in gallons (ASME ratings) or pounds
(DOT) water capacity. The Federal DOT (Department of Transportation) regulations
require periodic inspections and re-qualifications of cylinders.
American Society of Mechanical Engineers (AMSE) tanks or bulk containers
are generally used in the motorhomes and motorized products. These tanks are
permanently mounted on to the unit.
An alloy steel two-piece welded and brazed tank is used on all towable
products. 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 which are measured in
pounds, and the Manufacture date (one of the most important items). There is a
required 12 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.
