BYC A-1 MARINE
LIQUEFIED PETROLEUM GAS (LPG) SYSTEMS
A-1.9.3 Flexible LPG supply line shall be equipped with permanently attached end fittings, such as a swaged sleeve or sleeve and threaded insert.
A-1.9.4 Metal tubing shall be connected by means of flare fittings.
NOTE: “Long nut” flare fittings should be used. The short nut type fitting used in refrigeration
systems can precipitate fatigue failure due to vibration.
A-1.10.1 The fuel
supply line and fittings shall be tested with air pressure of not less than 5 psi (35 kPa). This test shall be performed after installation
, but prior to connection to the regulator
A-1.10.2 The cylinder valve shall be checked for leakage at its connection to the cylinder by application of a leak detection fluid prior to connection to the system.
A-1.10.3 After the above tests, the complete system shall be connected and shall be subjected to the following pressure test.
A-220.127.116.11 With the appliance valves off, open the cylinder supply valve. Close the cylinder supply valve. Observe the pressure gauge reading. The pressure indicated should remain constant for not less than three minutes. If any leakage is indicated by a drop in pressure, check the entire system with a leak detection fluid or detergent solution to locate the leak. Test solutions shall be noncorrosive and non-toxic. Repairs
shall be made before retesting and operating the system.
