It is important that adequately sized piping run directly to the
connection joint on the oven with as few tees and elbows as
possible to give maximum supply volume.

A suitable jointing compound which resists the break down action
of LPG must be used on every gas connection.

Check all gas connections for leakages using soapy water or other
gas detecting equipment.
