The maximum length of the heated sample gas line (inside diameter 4 mm)
is 30 m.
Install a shut-off valve in the sample gas line (definitely recommended with
pressurized sample gas), in order to provide a means for purging the gas
line system by feeding in an inert gas, e.g. nitrogen, from the gas sampling
point.
