Minimum clearances
In order to allow easy access to the appliance for
maintenance operations.
The appliance must be installed in accordance with the
clearances stated below.

The appliance was designed to use gases belonging to
the categories as shown in the following table.
COUNTRY
MODEL
NEXT OUTDOOR 11 LPG ZA EVO
NEXT OUTDOOR 16 LPG ZA EVO
South Africa

Make sure, using the labels on the packaging and the
data plate on the appliance itself, that the appliance is in
the correct country and that the gas category for which
the appliance was designed corresponds to one of the
categories available in the country where it will be used.
The gas supply piping must be created and measured
accordance with the maximum power of the appliance;
you should also make sure that the shut-off valve is the
right size and that it is connected correctly.
Before carrying out the installation, it is recommended
that the fuel pipes are cleaned thoroughly in order to
remove any residues which could prevent the appliance
from operating correctly.
Check that the supplied gas corresponds to the type of
gas for which the appliance was designed (see the data
plate located on the appliance itself).
It is also important to check that the pressure of the gas
(methane or LPG) you will be using to feed the appliance
generator may be reduced, causing inconvenience for the
user.

The excessive pressure device outlet (F) must be
connected to a drainage siphon which can be checked
visually in order to prevent maintenance procedures
causing harm to people, animals or property (the
