TRUMA COMBI BOILER
The instructions covering fitted equipment to
your caravan were correct at the time of going to print. Owners handbooks are updated
annually and we take great care to try and
ensure their accuracy. However, the Swift
Group Limited cannot accept responsibility for any changes that may be made in
specification or operating instructions to the
equipment described in this section after the
time of going to press.
Every care is taken to ensure that the information provided in this handbook is correct
and easy to understand.
Separate manufacturers’ leaflets on many
of the components are also included in the
Owner’s Pack provided with this caravan
and we recommend that you compare the
instructions in the handbook with the component manufacturers literature, to ensure
the information provided is as accurate as
possible.
If you are in any doubt as to how to operate the equipment in your caravan, please
contact the component manufacturer’s
service department on the telephone number shown on their component leaflet. If you
remain in any doubt, please contact your
supplying dealer.
Notice: In the interest of safety, replacement
parts for an appliance shall conform to the
appliance manufacturer’s specifications and
should be fitted by them or their authorised
agents.
Truma Combination Boiler
The Truma Combination boiler has been
designed to run on gas or electric power and
the optimum performance is obtained when
used in dual fuel mode, that is running on
gas and electric at the same time.
Running in dual mode has the following
benefits:
• Fastest possible heat up time, the gas burner
combines with an electric element to provide
energy to heat your hot water and warm your
caravan.
• The intelligent heat management system
automatically senses when the water and
room are nearing the required temperature
and then automatically turns off your gas
burner and operates solely on electric power,
conserving your gas.
• As hot water is used or the room cools the
Truma combination heater will continue to
operate on electric only until a point where
the demands necessitate that additional
gas power is required. An example for
such a demand could be for instance if the
exterior door was left open and the room
temperature dropped by 10 degrees in the
space of a few minutes, in this case the
intelligent heat management system would
decide the best way to get the room back
to the required temperature would be to use
both gas and electric at the same time.
Operating the Truma Combination system on
electric or gas only will result in longer heat up
times for hot water and the room temperature
in comparison to operating on dual fuel.
Operating on electric only may not in all cases
maintain a comfortable room temperature
especially in colder conditions.
The intelligent heat management system in
dual fuel mode allows the Truma Combination
boiler to prioritize the electric power source
over your gas, this will conserve your gas
supply.

Truma Heating System
and Air Flow
The Swift Group undertakes considerable
testing of our products in cold chambers to
ensure they meeting the BS EN 1649 Grade 3
standard and are usable in cold temperatures.
During this testing, the air flow on the blown air
outlets is defined and set by us.
Butterfly outlets
Blown air
The air ducting outlets on some models are
of the butterfly type, and if fitted these may be
opened or closed by adjusting the butterfly
valves. Twisting the disc in its housing directs
the flow in the direction required. One outlet
on each leg of the air ducting layout must
be kept open at all times, and when high
specification (Combi 6) heating systems are
fitted, depending on the number of blown air
outlets in the layout, butterfly fittings may not
be present.
Under no circumstances should the air ducting
outlets be blocked.
Note: The next instructions detail the
operation of the Combi Control Panel
- for further details of the Truma Combi
appliance, please see the following section.

Truma Combination Heating
System Function Description
The liquid gas heater Combi E is a warm-air
heater with integrated hot water boiler (10 liter
volume). The burner operates fan-supported,
which ensures trouble-free function even
when on the move. The unit also has heating
elements for electrical operation.
In winter operation the heater can be used to
heat the room and simultaneously warm water.
3 different options are available for operating
the unit.
– gas operation only Propane / Butane for
autonomous use
– electrical operation only 230 V for stationary
use on camp sites
– or gas and electrical operation – mixed
operation only possible in winter mode.
Winter operation (Space heating with
water heating)
In winter operation, the unit automatically
selects the required power setting according
to the temperature difference between the
temperature set on the control panel and the
current room temperature. When the boiler
is filled, the water is automatically heated as
well. The water temperature depends on the
selected operational mode and the heater
output. All 3 energy selection options can be
used for winter deployment.
With gas operation the unit automatically
selects the output level that is required.
Depending on the fuse protection at the
camping site, power of 900 W (3.9 A) or
1800 W (7.8 A) can be manually selected for
electrical operation.
If more output is required (e.g. heating up
or low outside temperatures) gas or mixed
operation should be selected so that enough
heating power is always available. With
mixed operation, 230 V electrical operation
is preferred if the power requirement is low
(e.g. for maintaining the room temperature).
The gas burner is not enabled until the power
requirement is higher, and is the first to switch
off during heat-up operations.
Summer operation (Water heating only)
Gas operation or 230 V electrical operation
is used for hot water preparation. The water
temperature can be set to 40 °C or 60 °C.
With gas operation the water is heated at
the lowest burner setting. Once the water
temperature is reached, the burner switches
off. Depending on the fuse protection at the
camping site, power of 900 W (3.9 A) or
1800 W (7.8 A) can be manually selected for
electrical operation. Mixed operation is not
possible. With this
setting the unit automatically selects electrical
operation. The gas burner is not enabled.
Repairs may only be carried out by
an expert
Guarantee claims, warranty claims and
acceptance of liability will be ruled out in the
event of the following:
– modifications to the unit
(including accessories),
– modifications to the exhaust duct and
the cowl,
– failure to use original Truma parts as
replacement parts and accessories,
– failure to follow the installation and operating
instructions.
It also becomes illegal to use the appliance,
and in some countries this even makes it illegal
to use the vehicle.
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
smell may be noticed for a short while. It is a
good idea to heat the device up several times
in summer operation (60 °C) and to make sure
that the area is well ventilated. Heat-sensitive
objects such as spray cans
or flammable liquids may not be stored in
the same compartment where the heater is
installed because, under certain conditions,
this area may be subject to elevated
temperatures.
Important operating notes

double duct must be checked regularly,
particularly at the end of long trips. Also check
the mounting of the appliance and the cowl.
Following a blow-back (misfire) always have
the exhaust gas system checked by an expert!
Always keep the cowl for the exhaust duct and
combustion air intake free of contamination
(slush, ice, leaves etc.). A number of hot air
outlets and the recirculated air intake openings
must be free so that the unit does not
overheat. The integrated temperature limiter
blocks the gas supply when the unit becomes
too hot.
Operating Instructions
Always observe the operating instructions and
“Important operating notes” prior to starting!
The vehicle owner is responsible for the correct
operation of the appliance. Before using for the
first time, it is essential to flush the entire water
supply system through with clean water. If
the heater is not being used, always drain the
water contents if there
is a risk of frost. There shall be no claims under
guarantee for damage caused by frost!
Room thermostat
To measure the room temperature, a room
temperature sensor is fitted to the furniture.
The exact location is determined by the layout
of the vehicle.
Taking into operation
Heating is possible without restrictions with
gas, electrical and mixed operation, with or
without water. Check to make sure the cowl is
unobstructed. Be sure to remove any covers
that may be present.
For operating on gas turn on gas cylinder and
open the shut off valve at the manifold. For
operating on electric operate the water heater
switch on the power supply unit. See page 71.
Filling the water heater
Switch on power for water pump (main or
pump switch) to prime the water system. Open
hot water taps in kitchen and bathroom, (set
preselecting mixing taps or single-lever fittings
to “hot”). Leave the fittings open for as long as
it takes for the boiler to displace the air and fill
up, and the water to flow without interruption.
If just the cold water system is being operated,
without using the water heater, the heater tank
also fills up with water. To avoid frost damage,
the boiler must be drained through the drain
valve, even if the boiler was not operated.
When connecting to a central water supply
(rural or city mains), a pressure reduction valve
must always be installed to prevent pressures
above 2.8 bar from developing in the water
heater.
Draining the water heater
Switch off power to water pump (main or
pump switch). Open hot water taps in kitchen
and bathroom. In order to check the water that
is flowing out, place an appropriate container
(capacity 10 litres) beneath the drain valve.
Open the drain valve which is situated next to
the boiler by lifting the yellow handle into the
vertical position.
Check whether all of the water in the boiler (10
itres) has been drained into the container via
the drain valve.
There shall be no claims under guarantee
for damage caused by frost!
Maintenance
Only original Truma parts may be used for
maintenance and repair work! Materials in the
device which come into contact with water
are suitable for use with drinking water (see
manufacturer‘s declaration: www.truma.com /
downloads / manufacturer‘s declaration).
Bio-film, deposits and limescale must be
removed using chemicals to protect the
unit from infestation by microorganisms.
Only chloride-free products must be used
in order to prevent damage to the unit. The
effectiveness of the use of chemicals to
combat microorganisms in the unit can be
increased by heating the water in the boiler to
70 °C at regular intervals. The unit must stay
switched on for at least 30 minutes and no
warm water may be removed. The residual
heat in the heat exchanger will heat the water
up to 70 °C.

Please read these instructions carefully
before using the boiler.
These instructions are approved for The Alde
Compact 3010 boiler fitted in caravans, motor
caravans and buildings in accordance with CE
no. EMC e5 02 0138, 845 BP-0003.
Installation and repairs may only be carried out
by a professional. National regulations must be
adhered to.
Boiler design
The boiler consists of three eccentrically- fitted
cylinders (heat exchanger, water jacket for the
heating system and, outermost, water jacket
for hot water). The two outer pipes, and their
ends and connections, are made of stainless
steel, while the heat exchanger is made of
aluminium.
The heat exchanger is divided into two semicircles. The burner is located in the upper
half, being the combustion chamber, and
the combustion gases are expelled through
the lower half. The burner unit is fitted on the
end of the heat exchanger. It consists of a
combustion fan, burner, solenoid valve and
intake/exhaust connections. Two heating
cartridges are fitted to the water jacket of the
heating system. Maximum output is 2 or 3 kW,
depending on model.
Description of functions
Using LPG
When LPG operation is selected on the control
panel, the combustion fan starts. When the
fan speed is correct, it signals the circuit
board that the boiler can be lit. The circuit
board sends ignition sparks to the spark plug
at the same time as it sends electricity to the
solenoid valve, which opens to allow gas in.
The burner ignites, and a sensor transmits a
signal back to the circuit board that the boiler
is lit, and the ignition spark stops. The burner
keeps burning until the boiler thermostat or the
room thermostat reaches the set temperature
reading.
Should the boiler go out for any reason, the
sensor is activated and a new attempt is made
to start the boiler (in about 10 seconds).
ALDE HEATING OPERATING INSTRUCTIONS
FITTED EQUIPMENT
113
Using the heating cartridge
Electrical operation is selected on the control
panel, the 12-volt relays on the circuit board
trip, allowing the 230 volt supply to reach the
electrical elements.
The heating cartridge is controlled in the same
way as the gas boiler.
Warm water
When only warm water is required, for example
during the summer, no settings need to be
made, the boiler will look after this function
automatically.
The pump will only start when the temperature
in the vehicle is lower than the set temperature
(see item 4, Control Panel). If the vehicle
temperature is higher, the pump will not start.
Important information
• The boiler must not be started if there is no
glycol in the system.
• The LPG boiler and heating cartridge may be
operated in parallel.
• The heating system may be heated up
without the warm water heater being filled
with fresh water.
• Always switch off the main isolator for the
boiler when the vehicle is not being used.
• Always drain the warm water heater of fresh
water if there is a risk of frost.
• The LPG boiler must not be operated when
refuelling the vehicle.
• When washing the vehicle, take care not to
get water in the venting.
! WARNING: Care should be taken
to ensure adequate ventilation of the flue
at all times. Its is inadvisable to inhale
exhaust fumes.
The Domestic hot water heater
The boiler is fitted with a built-in warm water
heater with a volume of approx. 8.5-litres fresh
water. The warm water heater can produce
around 12 litres of 40°C water per half-hour
(at a cold water temperature of 10°C). If the
heating cartridges are used instead of gas
for heating the boiler, the capacity is slightly
reduced. Always rinse out the heater before
it is used, particularly if it has not been in
operation for some time.
Note: The hot water is not intended for
drinking or cooking.
When the heater is in continuous use, it should
be emptied approx. once a month, to ensure
that a new air cushion is formed in the heater.
The air cushion is essential for absorbing
pressure surges in the heater.
Note: The warm water heater should
always be drained of fresh water when there
is a risk of frost and when the caravan is not
in use.
The warranty does not cover frost damage.
Draining the heater using the combined
safety/drain valve:
1. Switch off the freshwater pump
2. Open all water taps.
3. Then open the safety/drain valve by raising
the yellow lever (M) to a vertical position.
4. The heater will now drain directly below
the vehicle through the safety/drain valve
hose. Check that all the water is emptied out
(about 7-10 litres). Leave the valve in the open
position until the next time the heater is used.
Note: Check that the automatic check valve
(N) is open and is allowing air to enter the
heater when it is being drained, and that the
hose (O) is not blocked.

The heating cartridges
All Compact 3010s are fitted with two 230V
heating cartridges with a maximum output
of either 2100 or 3150W. Select the heating
cartridge output on the control panel.
Always check that the input supply of the
vehicle has the correct amperage in relation to
the selected output.
Note these ratings are for the boiler only.
1050W requires a 6 amp fuse/supply.
2100W requires a 10 amp fuse/supply.
3150W requires a 16 amp fuse/supply.
The circulation pump
A circulation pump is required to circulate the
heated glycol fluid. A 12V circulation pump is
fitted in the expansion tank.
An optional 230V circulation pump can be
fitted on the boiler. Selection of circulation
pump is made with a switch on the control
panel. The room thermostat on the control
panel controls the circulation pump, i.e.
switches it on or off according to the amount
of heat required.
System temperature
The boiler is set to a system temperature of
80°C, i.e. the temperature of the glycol fluid as
it circulates in the heating system.
Air circulation
In order to achieve the best possible result
from the principle of convected heat, it is
important to allow air to circulate freely under
bunks, and behind backrests and wallmounted cabinets.
If the vehicle has a fitted carpet, ensure that
the carpet does not obstruct the air supply to
the radiators.
It is just as important that cushions or
blankets do not interrupt the flow of air behind
backrests and wall cabinets.
Note: During the first weeks of ownership
customers may notice a drop in the glycol
level and/or blocked radiators. This is normal
as the system settles.
Maintaining the heating system
Winter camping
While camping during the winter, ensure that
the flue is kept clear of snow and ice, since the
inlet air to the LPG boiler enters through the
flue. Do not start the LPG boiler until the flue
is completely free of snow. A flue extension
(part no. 3000 320) for fitting on the roof is
recommended for winter camping.
Air stream
Convectors
The heating system
Regularly check the heating system’s fluid level
in the expansion tank. The level should be
about 1cm above the minimum indicator in a
cold tank. The heating system should be filled
with a mixture of water and glycol.
For preference, use high quality ready mixed
glycol (with inhibitor) intended for use in
aluminium heating systems.
If using concentrated glycol, the mixture
should consist of 50% water and 50% glycol.
If the heating system will be exposed to
temperatures below -25°C, the glycol content
must be increased, but not to more than
50%. Any vessels used for the liquid must be
spotlessly clean, and the pipes in the heating
system must be free of contamination. This will
prevent the growth of bacteria in the system.
ALDE HEATING OPERATING INSTRUCTIONS
FITTED EQUIPMENT
115
The glycol mixture should be changed every
second year, since its ability to protect against
corrosion, for example, will deteriorate. The
glycol content should be checked before
topping up with new liquid. This will ensure
that the concentration of glycol in the mixture
is not too high.
If the fluid level in the expansion tank falls for
reasons other than evaporation, please check
all joints, drain cocks and bleeder screws to
ensure that they are not leaking. If the glycolwater mixture leaks out, rinse with water and
wipe up.
Never allow the heating system to stand empty
of glycol.
Filling the system with glycol fluid
Note: 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.

Types of glycol
Various types of antifreeze (as used in car
radiators) are available from service stations,
car accessory shops and on line retailers and
these types of antifreeze can be used to top
up or replace the heating system fluid in the
Alde heating system.
Frost and corrosion damage are not covered
under warranty, so it is important that the
type purchased contains corrosion inhibitors
suitable for use with aluminium systems.
Always check the label, ask the retailer for
advice, or check with your supplying dealer
if unsure. Please note the corrosion inhibitor
will have a limited life, and after it expires, the
system will have no corrosion protection.
The fluid will usually be named as Ethylene
glycol, but may also be described as
monoethylene glycol, MEG, ethanediol, or
G12++. There is no industry standard for
the colour of the antifreeze, but as a general
guideline it indicates the type of corrosion
inhibitor:
Blue, Green - Silicate inhibitor, usually offering
2-year corrosion protection
Red, Orange - OAT inhibitor, usually offering
5-year corrosion protection
Purple, Magenta - G12++ Silicated OAT
inhibitor, usually offering 5 year corrosion
protection
It is important that antifreeze containing Silicate
inhibitor (Blue or Green) is not mixed with
antifreeze containing OAT inhibitor (Red or
Orange). To guarantee compatibility, there are
two options:
1. Match the colour, taking care to also check
the label on the antifreeze bottle, i.e. if the
system is filled with blue silicate-containing
antifreeze, top up with blue silicatecontaining antifreeze.
2. Use G12++ antifreeze which is compatible
with any of the other types of inhibitor
described.
FITTED EQUIPMENT
116
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 there are still issues, 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.
Twin-axle caravan:
The easiest way to bleed the heating system is
to place the vehicle on a sloping surface or to
raise one end of the vehicle using a jack. Bleed
the system as described above.
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 (> 11V).
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
(230V ~) 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.
