4.4.1 Olive screw connection
Observe the following points during installation:

Establish all cutting ring screw connections according to the
corresponding regulations for the installation of cutting ring screw
connections (e�g�ENISO8434-1, DIN EN 1949)�

Make sure that the olive and the tapered seal are in perfect
condition�

Lay gas pipes without tension so that, once the gas pipe has been
installed, no force is being exerted on the gas pressure regulator�

Use appropriate protection (soft inserts, rubber bushings,
bulkhead unions) to prevent gas pipes chafing at fastening and
connection points�

Tighten cutting ring screw connections for 8mm gas pipes with a
17mm spanner�

Tighten cutting ring screw connections for 10mm gas pipes with
a 19mm spanner�

Use a second 20mm spanner to hold the cutting ring screw
connection in place�

If necessary, the reducer union RST10xRVS8 can be used to
connect a 8mm gas pipe to a 10mm regulator outlet�
4.4.2 Threaded union
•
Only use seals that are in perfect condition� Never use self-made
seals; instead, only use Truma original spare parts�
•
Use the included screw aid to attach and remove the high-pres-
sure hose or the gas filter*� The screw aid guarantees the required
tightening torque� Damage to the union or the seal is therefore
prevented�
4.4.3 Installing

Before installing the gas pressure regulator, take note of the year
of construction for the test certificate� The CE test number is listed
in the technical data in the operating instructions�
