FIllING THE SySTEM
WITH GlyCOl FlUID
NB! Any vessels used to carry the
fluid must be spotlessly clean and the
pipes in the system must be free of
contamination. This will prevent the
growth of bacteria in the system.
The system is filled through the
expansion tank, either manually or
using the Alde filling pump which both
tops up and bleeds the system. For
manual filling, unfasten the circulation
pump nut (R) and lift the pump (S)
out of the tank. Slowly pour the glycol
mixture into the tank. Bleed the system.
Top up with more liquid if the level has
fallen after bleeding. Bleed a newly-
filled system regularly during the first
days the heating system is in operation.

BlEEDING THE SySTEM
Depending on how the pipes have been
fitted, air pockets may form when the
system is filled with glycol fluid.
A sign that there is air trapped in the
system is that the heat released into the
pipes only extends a metre or so from
the boiler even though the circulation
pump is operating.
In newly-filled systems, small air
bubbles can form in the expansion
tank, creating a murmuring sound. If the
circulation pump is stopped for a few
seconds, the bubbles will disappear.
Bleeding:
If a bleeder screw is fitted to the
outgoing pipe, open this bleeder screw
and leave it open until it starts to
discharge water.
If the boiler is fitted with an automatic
bleeder, there is no need to bleed it
manually. Start the LPG boiler. The
circulation pump should be switched off.

Open the remaining bleeder screws
in the system (please refer to the
instruction manual of the vehicle for
their locations). Leave the bleeder
screws open until they start discharging
fluid, and then close them. Start the
circulation pump and let it run for
a while. Check that the pipes and
radiators around the vehicle are heating
up.
If they still fail to heat up, try the
following:
Single-axle caravan: Stop the
circulation pump. Lower the front of
the caravan as far as possible. Leave
it in this position for a few minutes to
allow the air to travel upwards in the
system. Open the bleeder screw at
the highest point. Leave it open until it
discharges glycol fluid. Raise the front
of the caravan as far as possible and
repeat the procedure in this position.
Then position the caravan horizontally
and start the circulation pump. Check
that the pipes and radiators around the
vehicle are heating up.
Motor caravan or twin-axle caravan:
The easiest way to bleed the heating
system is to place the vehicle on a
S
sloping surface or to raise one end
R
of the vehicle using a jack. Bleed the
system as described above.
ABOUT lPG
The properties of lPG
LPG is a petroleum product, formally
known as "liquid petroleum gas". It is
mainly made up of propane and butane
gas. The advantage of propane is that
it remains gaseous at temperatures
as low as -40°, while butane loses
effectiveness at +10°C. For this reason,
propane is used in colder countries.
The cylinders contain LPG both in liquid
and gaseous form. When the cylinders
are filled, the pressure turns the gas
into liquid. When the cylinder valve is
opened, the LPG becomes a gas again.
The risk involved in using LPG is
that any leaking gas may ignite and
explode. Since LPG is heavier than air,
any leaking gas will collect at the lowest
point.
LPG contains no toxic substances, but
breathing in concentrated gas may
have a certain anaesthetising effect,
and can also result in shortness of
breath and symptoms of suffocation.
These symptoms quickly disappear if
the sufferer breathes in ordinary air or
oxygen.
Naturally, it is inadvisable to inhale
either LPG or exhaust fumes. To
make it easier to detect gas leaks, a
substance with a distinctly rank smell
has been added.
Combustion
Complete combustion of LPG only
generates carbon dioxide (CO
water vapour, just like the air we exhale.
A good supply of air is essential to
ensure complete combustion. The
flame should burn with a weak blue
colour, the centre of the flame should
be blue/green. LPG is extremely
environmentally compatible and does
not generate any soot during complete
combustion. It can be stored in
cylinders for an unlimited time period,
without any deterioration of quality.
Pressure
The LPG burner usually works at
a lower pressure than that in the
cylinder. Low pressure (0-50 mbar)
and intermediate pressure (50 mbar-
2.0 bar) are created by allowing the
gas to pass through a reduction
valve. High pressure (over 2.0 bar),
is unreduced pressure mainly used
in camping equipment. Low pressure
and intermediate pressure are always
reduced pressure.

FAUlT FINDING

The boiler does not start
1. No LPG? Incorrect type for
conditions?
2. Is the main tap fully open?
3. If the boiler has not been operated
for some time, or if the gas cylinder
has been changed, it may take
longer than normal to light the boiler.
4. Check that the boiler is connected to
the electricity supply (> 11 V).
5. Check that the fuse (T) for the boiler
is intact.
6. Check whether the electric
connections on the boiler are
securely in position.
If none of the above helps, contact a
service workshop.
The heating cartridge is not
working
1. Check that there is an electricity
supply (230 V ~) to the heating
cartridge.
2. Check that the relays fitted to the
boiler come on (a slight click can
be heard from the relays when the
heating cartridge is switched on at
the control panel).
If none of the above helps, contact a
service workshop.
