Cut off the ventilation hose approx. 20 mm below the floor of
the vehicle at an angle of 45° to the direction of travel.

Produce connection (22) for cold water supply between
safety/drain valve (14) and elbow (13 – lower pipe) on water
heater.
Route the hot water pipe (23) from the elbow with integrated
breather valve (12 – upper pipe) to the hot water consumers.
Gas connection
38
The operating pressure for the gas supply is 30 mbar
and must correspond to the operating pressure of the
appliance (see name plate).
The 8 mm gas supply line is connected to the connection noz-
zle (38) with cutting ring connection. The cutting rings are to
be selected according to the gas pipe used (for copper pipe:
support sleeves and brass cutting ring as supplied). Carefully
hold in place with a second wrench when tightening!
Before connecting to the water heater make sure that the gas
lines are free from dirt, chips and such!
Route the pipes in such a way that the appliance can be
removed again for servicing.
In areas frequented by people, keep the number of parting
connections in the gas supply line to an technically feasible
minimum.
The entire system must accord with the technical and
administrative provisions of the individual country of use
(e.g. EN 1949 for vehicles). National specifications and
regulations must be respected.
Flexible water hose routing
As special accessories Truma supplies the water connectors
(12 + 13) and safety/drain (14) valve with a 10 mm diameter
hose nipple (please refer to page 14).
Pressure-resistant (up to 4.5 bar) and hot water-resistant water
hoses in food quality with an internal diameter of 10 mm must
be used.
Route water hoses so that they are as short and free
of kinks as possible. All hose connections must be
secured using hose clamps (also for cold water)! Pressures
of up to 4.5 bar can occur in the safety/drain valve (also with
submergible pumps) because of the heat of the water and the
resulting expansion.
All hot water hoses should be routed in a descending
manner to the safety/drain valve! Otherwise no guaran-
tee of protection from frost!

Install the safety/drain valve
(14) at a place which is
easily accessible, near the
water heater. Drill hole with
18 mm diameter and pass
through discharge socket
with hose (15). Fasten safety/
drain valve with 2 screws.
The draining is to be directly
to the outside at a position
protected against splash
water (apply splash guard, if
necessary).
Water pipe routing
Connect cold water supply (16) to safety/drain valve (14).
Direction of flow is unimportant.

Slide elbow fitting (13) onto cold water connecting pipe (lower
pipe) and elbow fitting with integrated ventilating valve (12)
onto hot water connecting pipe (upper pipe) of water heater
as far as it will go. Pull in opposite direction in order to make
sure the elbow fittings are securely attached.
Push the venting hose, external diameter 11 mm (20), onto
the hose grommet of the venting valve (21), and lay it to the
outside without any kinks. Ensure that the bend radius is not
smaller than 40 mm.
