Direction of travel
3. Produce connection (22) for cold water supply between
safety/drain valve (14) and elbow (13 – lower pipe) on water
heater.
4. 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
(or 28 mbar butane/37 mbar propane) and must corre-
spond 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 adminis-
trative provisions of the individual country of use (e.g. EN 1949
for vehicles). National specifications and regulations must be
respected.

2. Screw elbow with integrat-
ed breather valve (12) to hot
water connection pipe (upper
pipe) and elbow without
breather valve (13) to cold
water connecting pipe (lower
pipe).
Slide on nut (17), tension ring
(18) and O-ring (19). Assem-
ble screw connector and
connecting pipe and fasten
together using nut (17).
Slide ventilation hose with
11 mm outer diameter (20)
onto the breather valve hose
nozzle (21) and route towards
the outside. Do not allow the
radius of the arc to be less
than 40 mm.
Cut off the ventilation hose
approx. 20 mm below the
floor of the vehicle at an an-
gle of 45° to the direction of
travel.
Installation of the control panels
When using control panels which are specific to the ve-
hicle or the manufacturer, the electrical connection must
be established in accordance with the Truma interface descrip-
tions (refer to Electrical connection 230 V). Any modification
made to the Truma components pertaining to this will lead to
the invalidation of the guarantee, as well as to the exclusion of
any claims for liability. The installer (manufacturer) is responsi-
ble for providing instructions for use for the user as well as for
identification printing on the control panels.
When selecting the location, bear in mind that the control pan-
els must not be subjected to direct radiant heat. Length of con-
nection cable 3 m. If required, a cable extension of 5 m can be
supplied (please refer to page 11).

If it is not possible to install the control panels flush with
the surface, Truma can provide a surface-mounting frame
(25) on request, as a special accessory (Part no. 40000-52600).
1. The control panel for gas operation (26) and (if provided) the
control panel for electrical operation (27) should be fitted next
to one another if at all possible (distance between centres of
holes 66 mm).
2. In each case, drill a hole with diameter 55 mm (distance
between centres of holes 66 mm).
3. Plug the control panel cable (28) to the control panel for gas
operation (26) and then fit on the rear cover cap (29) as a
stress-relieving device.
4. Push the cable through to the rear and lay the connection
cable (28 + 30) to the water heater.
5. Lay the connection cable with the orange multipole connec-
tor (28) to the 12 V control electronics unit (for connection see
Point 6, electrical connection 12 V).
6. Secure both control panels with 4 screws (31) each and fit
the cover frame (32) on them.
To round off the appearance of the cover frame, Truma
can provide side pieces (33) as special accessories in
8 different colours (please ask your dealer).
