When the installation process is complete, check the pipe
fittings for leaks using a soapy solution. Never use a flame.

Should the gas pressure used be different (or vary slightly)
from the recommended pressure, a suitable pressure
regulator must be fitted to the inlet pipe (in order to comply
with current national regulations).
