Leak Test

Turn the gas off.
•
Using soapy water applied with a
sponge, or with a brush, cover all of
the gas joints with a liberal amount
of suds.
Stage 2
•
Turn the gas on.
•
Inspect the joint for leaks.

perform a leak test
to check for gas leaks between regulator and cylinder, and
between regulator and braided hose.
