Gas connection
The gas system must accord with the technical and ad-
ministrative provisions of the individual country of use
(in Australia, AS/NZS 5601.2 – LP Gas installations).
• The nominal gas system pressure must be 2.75 kPa.
• For gas pipe sizing refer to AS/NZS 5601.2 – LP Gas
installations.
• Install the gas piping so that the heater can be dismantled
easily for servicing.
• In the gas piping, limit the number of separation points in
rooms used by people to a technically necessary minimum
• Before you connect the gas piping to the
Pre-pressure regulator VarioHeat, make sure that it is free of
dirt, metal filings, etc.
• The gas connection fitting on the heater must not be short-
ened or bent.
• When you are tightening the connection, use a second
wrench as a brace.
Installing the VarioHeat pre-pressure regulator
The VarioHeat pre-pressure regulator is adjusted in the
factory. During operation, the pressure at the gas pres-
sure test point (3) must be1.8 – 2.2 kPa. If the VarioHeat pre-
pressure regulator cannot be installed to perform correctly,
please contact Dometic Service Centre.
The VarioHeat pre-pressure regulator must be installed to en-
sure safe operation of the VarioHeat.
The VarioHeat pre-pressure regulator can be installed in
any direction.
• Connect the VarioHeat pre-pressure regulator (1) to the gas
inlet connection (2) in accordance with the installation regu-
lations for olive screw connections (e.g. ISO 8434-1). When
you are tightening the connection, use a second wrench as
a brace.

After installation, you must check gas supply line
for leaks in accordance with the pressure drop
method.
•
Do not
use matches, candles or other sources of ignition
when checking for gas leaks.
Functional check
Always observe the operating instructions prior to starting!
1. Start the appliance
2. Check all functions of the heater in accordance with the op-
erating instructions.
If faults occurring during operation of the appliance,
refer to “Troubleshooting” in the Operating instruc-
tions. If the heater cannot be adjusted to perform correctly,
please contact Dometic Service Centre.
3. To test the warm air distribution, at maximum fan level, the
measured duct static pressure must be within the heater
specifications (see below).
4. Provide operating instructions to the vehicle owner.
– The year of initial operation must be marked on the type
plate.
The appliance is now ready for normal operation and use.
Warning
• The installer or vehicle owner must attach the yellow sticker
with the warning that is supplied with the device at a place
in the vehicle that is visible for every user (e.g. on the ward-
robe door).
More stickers can be obtained from Truma.
