3.1 Installation

1. A standard 1m length of sampling tube is supplied. Cut the open end so the tube is
the correct length: the gas entry window is half way across the duct.
2. To avoid the adverse effects of turbulence, the duct mounting kit should be installed in
the centre of a straight section of duct which has a length at least six times its width.
If the section of duct is shorter, the adequacy of the flow should be tested with a mix
of gas and air in the duct.
3. Check the air flow direction in the air duct system.
4. Use the duct mount boss to mark up the duct ready for drilling the required holes as
indicated on Diagram 4. Make sure that the centre line is positioned equidistant from
the two edges of the duct.
