LPG may cause corrosion; piping and fitting materials must be resistant to this
corrosion.
Vertical gas pipes must be equipped with a siphon and provided with a drain for the con-
densate that may form inside the pipe during cold periods. It may also be necessary to
insulate the gas pipe to prevent the formation of excessive condensate.
In any case, provide an isolation valve (ball valve) on the gas supply line, to isolate the
appliance when required.
