Gas installation
Installation notes
The gas supply pipe must be connected to the connection on the unit via a shutoff valve (essential
requirement), which is installed in the immediate vicinity of the unit.
When steel gas pipes are in use,
it is essential that a sediment separator be fitted
between the shutoff valve and the unit connection.
The following connection data must be adhered to:

pressure tested

front or side service doors.

the applicable local building
and installation regulations

All work concerning the water installation must be performed only by
adequately qualified
personnel
