Note containing information and tips.
General safety notes
The use of upright gas cylinders from which
gas is taken in the gas phase is mandatory for the operation of gas regulators, gas
equipment and gas systems. Gas cylinders from
which gas is taken in the liquid phase (e. g. for
fork lifts) must not be used, since they would
result in damage to the gas system.
In event of leaks in the gas system or if there
is a smell of gas:
– extinguish all naked flames
– do not smoke
– switch off all appliances
– shut off the gas cylinder
– open the windows and doors
– do not actuate any electrical switches
– have the entire system checked by an
expert!
Repairs may only be carried out by an
expert.
– This device may be used by children aged 8
years or above and by persons with reduced
physical, sensory or mental capabilities or lack
of experience and / or knowledge, only if they
are supervised or have been given instruction
with regard to the safe use of the device and
have understood the potential risks. Children
must not use the device as a toy.
– To avoid the risk of accidental resetting of
the over-temperature guard, the device may
not be supplied with power via an external
contactor, such as e.g. a timer, nor may it be
connected to a power circuit that is regularly
switched on or off via a device.
– Any discharge pipe connected to the safety
(pressure relief) valve is to be installed in a
continuously downward direction and in a
frost free ambient.
– Before gaining access to any and all terminals, please ensure all supply circuits are
disconnected (i.e. 230 – 240 V and 12 V) and
gas supply is securely turned off.
– Any work involving connection or interconnecting wiring must be conducted by a licensed electrician.
– Any modifications to the unit, including accessories and cowl, or the use of spare parts
and accessories that are important to the
operation of the system that are not original
Truma parts and failure to follow the installation and operating instructions will cancel
the warranty and indemnify Truma from any
liability claims. It also becomes illegal to use
the appliance, and in some countries this
even makes it illegal to use the vehicle.
– The operating pressure for the gas supply
is 2.75 kPa (AUS – Propane, NZ – LPG) and
must correspond to the operating pressure
of the appliance (see data plate).
– LPG Systems and pressure regulators must
comply with the technical and administrative regulations of the country in which the
appliance is used. For your own safety it is
absolutely necessary to have the complete
gas installation regularly checked by an expert (at least every 2 years). The vehicle owner is always responsible for arranging the
gas inspection.
– Do not operate when travelling.
Danger
Failure to operate the relief valve easing gear
at least once every six months may result in
the water heater splitting. Continuous leakage
of water from the valve may indicate a problem with the water heater!
– Water may drip from the discharge pipe of
the pressure relief device and this pipe must
be left open to the atmosphere.
– The pressure relief device is to be operated
regularly to
remove lime deposits and to verify that it is
not blocked.
– Do not operate the water heater when refuelling the vehicle and when in the garage.
– Items sensitive to heat (e. g. spray cans)
must not be stored in the installation area,
since excess temperatures may under circumstances be incurred there.
– During the initial operation of a brand new
appliance (or after it has not been used for
some time), a slight amount of fumes and a
slight smell may be noticed for a short while.

Operating instructions
1. Disconnect power for water pump (main switch or pump
switch).
Always observe the operating instructions prior to
starting! The vehicle owner is responsible for the correct
operation of the appliance.
2. Open hot water taps in bathroom and kitchen.
Before using the first time, it is essential to flush the
entire water supply through with clean warm water.
Always mount the cowl cap when the water heater is not being operated! Drain the water heater if there is a risk of frost!
There shall be no claims under guarantee for damage
caused by frost!
4. The water heater is now drained directly to the outside via
the drain valve. Check that the water contents have been
completely drained (10 litres or 14 litres).
3. Open safety/drain valve: Lever in vertical position, position (f).
Switching on gas operation
Always remove the cowl cover prior to operating the
water heater!
Boiler
60°
If connecting to a central water supply (rural or city connection)
or when using more powerful pumps, a pressure reducer
must be used which prevents pressures of greater than
400 kPa occurring in the Boiler.
Filling the Truma Boiler with water
1. Check that the drain valve in the cold water intake is
closed: Lever should be in horizontal position, position (e).

When using the vehicle switches
Refer to operating instructions of the vehicle manufacturer or
see switch labels.
2. Open hot tap in bathroom or kitchen, with pre-selecting
mixing taps or single-lever fittings set to “hot”.
3. Switch on power for water pump (main switch or pump
switch).
4. If there is air in the gas supply line, it may take up to a minute before the gas is available for combustion. If the
appliance switches to “Failure” during this period, switch off
the appliance – wait 10 minutes – and switch on again!
Leave the tap open to let air escape while the water heater is
filling. The heater is filled when water flows out of the tap.
Switching off gas operation
Residues of frozen water can prevent filling if there is a frost.
The water heater can be defrosted by switching on the heater
for a short period (max. 2 minutes). Frozen pipes can be defrosted by heating the room.
Switch off the water heater to position (c).
If just the cold water system is being used, without
water heater, the heater tank is also filled up with water.
In order to avoid damage through frost, the water contents
must be drained by actuating the drain valve, also when the
heater has not been used. As an alternative, two shut-off
valves, resistant to hot water, can be fitted in front of the cold
and hot water connection.
Fig.4
Draining the water heater
If the mobile home is not used during periods of frost,
it is essential that the Boiler be emptied.
If the water heater is not to be used for a longer period,
mount cowl cover (non-observance of this point can lead to
the function of the appliance being impaired through water,
dirt or insects), close stop cock valve in the gas supply line
and close the gas cylinder.
Before setting off on any journey, fit cowl cap with the
boiler switched off. Please ensure that it is secure and
has locked into place (risk of accident). Defective cowl caps
must not be used.
Drain the water heater if there is a risk of frost! There
shall be no claim under guarantee if this point is not
observed.

Regulations
Choice of location
1. Always install the appliance in such a way that it is easily
accessible for service work at all times and can be easily
removed and installed.
2. Locate the heater in such a way that the cowl can be
mounted on the outside on a surface which is as straight
and smooth as possible.
This outside surface must be exposed to wind from all directions and, if possible, there should be no trim strips or
covers in this area, mount heater on an appropriate base, if
necessary.
The cowl must be placed in such a way that the exhaust gas
cannot find its way into the vehicle interior. For this reason,
choose a location where there are no opening windows, skylights or ventilation openings directly above the cowl or for
50 cm on either side. If this is not possible, a warning plate
must be placed on the inside of the window (or skylight) stating that it must be kept closed while the heater is operating.
In this case refrigerator ventilations must be tight-sealed from
the interior of the vehicle.
AUS:
Refer to AS5601 – Gas Installations, for location requirements
of the flue terminal.
NZ:
Refer to NZS 5428 – LPG installations
Any modifications to the unit, including accessories and cowl,
or the use of spare parts and accessories that are important to
the operation of the system that are not original Truma parts
and failure to follow the installation and operating instructions
will cancel the warranty and indemnify Truma from any liability claims. It also becomes illegal to use the appliance, and in
some countries this even makes it illegal to use the vehicle.
Installation of the water heater
The operating pressure for the gas supply is 2.75 kPa
(AUS – Propane, NZ – LPG) and must correspond to the operating pressure of the appliance (see data plate).
Drill 4 holes (C) with 10 mm dia. through the wall. Drill hole
(E) with 15 mm dia. for condensation tube (also possible from
the outside = F).
After it has been installed, the device must be disconnected
from the power supply. It can be disconnected by ensuring
that the power plug is accessible or by installing a switch in
the fixed power supply installation.
2. Position template on the outside of the wall. The markings
(C) must be above the through-holes. Saw cut-out section for
cowl (D) 92 x 168 mm.
When installing the appliance always observe the technical
and administrative rules and regulations of the country in
which the vehicle is to be registered, for the first time!
Water heater kit
1. Position template for cowl opening on the inside of the
wall.
A = Bottom edge of heater
B = Lateral edge of heater
If the distance between outside wall and heater is more than
35 mm you must use the cowl extension VBO 2 (please refer
to page 12) with an additional length of 50 mm. Saw out
100 x 176 mm along the dashed line.
If there are any cavities in the area of the cowl, pack these
with pieces of wood so as to be able to tighten the screws.
The finished hole should be 168 mm high and 92 mm wide.
The water heater kit contains:
1 Assembled water heater
1 Cowl assembly with screws
1 Hot water connector (12 mm rigid piping)
1 Cold water connector (12 mm rigid piping)

Fig. 9
Cut out trim strips or such on the vehicle or place supports
beneath them so as to make the cowl lie flat.
Place a support beneath the heater if the walls are sloping. An
angle of inclination of 10 degrees is not to be exceeded.
3. Insert heater with cowl body (1) through the wall cutout (2),
allow approx. 5 mm to project out of the wall. Mount sealing
frame (3 – the anti-twisting device ensures correct fitting!).
Pre-drill holes for the 6 fastening bolts (4).
Water connection
All pressure and submergible waterpumps can be used for
operating the water heater.
In order to guarantee complete emptying of the
water content and to prevent pressures of greater
than 400 kPa occurring in the boiler, the enclosed pressure reducer (10), the enclosed water connectors (12 + 13)
and the enclosed safety (pressure relief) drain valve (14)
must be used!
When using pressure pumps with high switching hysteresis,
hot water may flow back through the cold water tap. To prevent the backflow, we recommend that a non-return valve
(nrv – not included in the scope of supply) be fitted between
the outlet to the cold water tap and the drain valve.

The supplied water connectors (12 + 13) and safety/drain
valve (14) have a 12 mm rigid piping connection (e. g.
John Guest System). For connecting to rigid pipes with other
diameters appropiate adapters (not included in scope of delivery) must be used.
As special accessories Truma supplies the water connectors
(12 + 13) and safety/drain valve (14) with a 10 mm / 3/8" diameter hose nipple (please refer to page 12).
Route water pipes so that they are as short and free of
kinks as possible (hose connections must be secured
using hose clamps – also for cold water! – pressures of up
to 400 kPa 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 pipes should be routed in a descending
manner to the safety/drain valve! Otherwise no guarantee of protection from frost!
