NOTICE
Testing for gas leaks with a flame can cause a fire or explosion that can lead to severe
personal injury or death. Use approved methods only.
After assembly, and before initial operation, all fuel system connections, hose valves, regulators
and fittings must be tested and proven free of leaks using a soap-and-water (or equivalent)
solution while the system is under gas or air pressure of at least 1.5 times the supply pressure
or 3 psi (20.7 kPa) minimum.
• Apply the soap-and-water solution to all fuel system connections, hose valves, regulators
and fittings.
• When the system is running, bubbles will form where air/pressure is leaking from the
system.
Other approved methods of detecting leaks can be used if appropriate. DO NOT use a flame to
test for gas leaks.
