Installation instructions

In-vehicle installations must comply with
the technical and administrative regu-
lations of the respective country of use
(e.g. EN 1648, VDE 0100-721). In other
countries, the relevant regulations must
be observed. National regulations and
rules must be followed.
Disregarding installation instructions or erroneous
installation can put people in danger and cause
damage to property.
Observe the ESD regulations!

Intended use

The Truma VarioHeat eco / Truma VarioHeat comfort liquid
gas heater was designed for installation in motor homes (ve-
hicle class M1) and caravans (vehicle class O).
The equipment must not be installed in buses (vehicle classes
M2 and M3) and in vehicles for transporting hazardous goods.

Approval

Directive UN ECE R 122 stipulates that a safety shut-off de-
vice is required if motor homes and caravans are heated while
driving. The Truma MonoControl CS gas pressure regulation
system satisfies this requirement. Throughout Europe, a
type-tested liquid gas heater may be used while driving (ac-
cording to the directive UN ECE R 122) if the system includes
a gas pressure regulation system with an appropriately con-
figured gas installation. National regulations and rules must
be followed.
The heater is approved for installation in passenger vehicles
(class M1 motor homes) with a maximum of 8 seats excluding
the driver's seat, and for trailers (class O caravans).

Regulations

Guarantee claims, warranty claims and acceptance of liability
will be ruled out in the event of the following:
– Modifications to the device (including accessories),
– Modifications to the exhaust duct and the cowl,
– Use of replacement and accessory parts other than original
Truma parts,
– Failure to follow the installation and operating instructions.
The device's operating permit, and consequently also the ve-
hicle's operating permit in some countries, are also rendered
void.
Installation instructions

Vehicles

The operating pressure of the gas supply (30 mbar) and of the
heater (see type plate) must be the same.
In Germany, only pressure regulating equipment that complies
with DIN EN 16129 (in vehicles) with a fixed output pressure
of 30 mbar may be used for the gas system. The flow rate
of the pressure regulating equipment must correspond to at
least the maximum consumption of all devices installed by the
system manufacturer.
If exhaust gas is discharged beneath the floor, it must be en-
sured that the vehicle floor is sealed. In addition, at least three
sides beneath the vehicle floor must be free to ensure that the
exhaust gas can escape unhindered (snow, stone guard etc.).
Cowls must be positioned so that no exhaust gases can enter
the interior. The exhaust duct must always be routed at least
as far as the side wall.

The installation of the device in vehicles must comply with
the technical and administrative regulations of the respective
country of use (e.g. EN 1949). The national legislation and
regulations (e.g. DVGW Work Sheet G 607 for vehicles in Ger-
many) must be observed.
The relevant employer's liability insurance association accident
prevention regulations must be observed in Germany for ve-
hicles used for commercial purposes (DGUV regulation 79 –
formerly BGV D 34).
In other countries, the relevant regulations must be observed.
More information about the regulations in the relevant desti-
nation countries can be requested from our foreign represent-
atives (see www.truma.com).

Water supply

If a water supply is being installed in the vehicle, it must be
ensured that sufficient room is left between the water lines
and the heat source (e.g. heater, warm air duct).
A water pipe may only be routed at a distance of 1.5 m from
the heater at the warm air duct. The Truma SC hose clip (part
no.: 40712-01) can be used from this distance on. With paral-
lel routing (e.g. through a wall) a spacer (e.g. insulation) must
be fitted in order to avoid contact.
