CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply
noncorrosive leak detection fluid
to all joints. Bubbles forming show
a leak. Correct all leaks at once.
PRESSURE TESTING GAS SUPPLY
