Attention: Without heater
operation, the safety/drain
valve can only be closed
again at temperatures above
8°C!
Filling the boiler
1. Close electrical safety/
drain valve at the control
knob by lifting up (position g).
Attention: At temperatures
of around 8°C and less,
switch on the heater or water
heater first, to make sure the
valve does not open again!
2. Switch on power for water
pump (main switch or pump
switch).
3. Open hot water taps in
kitchen and bathroom, (set
preselecting mixing taps or
single-lever fittings to „hot“).
Leave taps open until the wa-
ter heater has forced out air
and filled up with water and
water is flowing out of the
taps.
Draining the water
heater
1. Interrupt power for water
pump (main switch or pump
switch).
2. Open hot water taps in
kitchen and bathroom.
3. Open electrical safety/drain
valve at control knob by
pressing in (position h).
The water heater is now
drained directly to the outside
via the safety/drain valve.
Check that the entire water
contents is drained (12 litres).
Attention: The draining
socket of the electrical
safety/drain valve must
always be kept clear (free
from slush, ice, leaves
etc.)!
There shall be no guaran-
tee claims for damage
caused by frost!
Maintenance
Note: The water container
used is made of VA stainless
steel, which is foodstuff-com-
patible.
Use wine vinegar for descal-
ing the water heater, this be-
ing introduced into the appli-
ance via the water supply. Al-
low the product to react and
then thoroughly flush out the
appliance with plenty of fresh
water. To sterilise the water
we recommend „Certisil-
Argento“. Other products,
particularly those containing
chlorine are unsuitable.
To avoid infestation by micro-
organisms, the boiler must be
heated to 70°C at regular in-
tervals (only possible in win-
ter operation).
Do not use the water as
drinking water!
Fuses
The appliance fuses are on
the electronic control unit on
the appliance.
Important note: Only replace
the miniature fuse F1 on the
p.c.b with a fuse of the same
type (4 AT - slow-action).
Attention: The fuse F2 is on-
ly to be replaced by an ex-
pert.

Important operating
notes
1. If the cowl has been placed
in the vicinity of an opening
window (or skylight) - particu-
lary if placed directly under-
neath - the window or sky-
light must be kept closed
while the heater is operating
(see warning plate).
2. The integrity and tight fit of
the exhaust gas double duct
must be checked regularly,
particularly at the end of long
trips. Also check the mounting
of the appliance and the cowl.
3. Following a blow-back
(misfire) always have the ex-
haust gas system checked by
an expert!
4. Always keep the cowl for
the exhaust duct and com-
bustion air intake free of cont-
amination (slush, leaves etc.).
5. Note for winter campers:
With a roof cowl it is recom-
mended to use the cowl ex-
tension (Art.-no. 34070-01) if
the vehicle is used for winter
camping. This must be re-
moved when the vehicle is
moving!
If caravans are fitted with a
double-skin roof, the exhaust
cowl must be led through the
roof using this cowl extension
and fastened with the clamp-
ing rings (Art. no. 34080-01).
6. The installed temperature
limiter shuts off the gas sup-
ply if the appliance becomes
too hot. Therefore do not shut
the warm air outlets and the
opening for the returning cir-
culating air.
7. If the electronic control
p.c.b. is defective, return it
well packed. If you fail to do
so, guarantee claims shall no
longer be valid. Only use orig-
inal p.c.b. as a spare part!
8. In Germany, according to
Section 22a of StVZO, the
heat exchanger of heaters
built into motor vehicles must
be replaced with an original
part by the manufacturer or
authorized workshops, ten
years after the year of first
registration (this date must be
scribed on the name plate).
The heater is then to be fitted
with a plate indicating the
selling date of the heat ex-
changer and the word
„original spare part“ (if ex-
haust ducts are conducted
through rooms frequented by
people, these must also be
replaced by original spare
parts after 10 years).
The vehicle owner is the
person responsible for ar-
ranging the inspection and
the replacing of the parts.
General safety notes
If the gas system is leak-
ing or if there is a smell of
gas:
- extinguish all naked
flames!
- do not smoke!
- switch off the appliances!
- shut off the gas cylinder!
- open windows and door!
- do not actuate any
electrical switches!
- have the entire system
checked by an expert.
1. Repairs may only be
carried out by an expert.
Attention: A new O-ring
must always be installed after
dismantling the exhaust duct!
