Heater operation
Wallas heaters 26CC and 40CC have been designed especially for use in holiday
cottages.
Lightfurnaceoil,dieseloilorparafncanbeusedtofuelthedevice.Theheateris
fed with fuel from a separate tank, which is positioned below the heater. The heater
is powered by a 12-volt battery, which can be recharged, for example, by a solar
cell, wind generator or a mains power adapter.
The combustion air is fed in from outside the device and its circulation is complete-
lyenclosed,andbalancedwiththeue-gasexhausthead,whicheliminatesthe
effect of wind pressure on the combustion.
The heater’s evaporation burner is activated automatically when the device is
started. The glow plug in the burner ignites the fuel that has been pumped into the
burner.Theglowtimeisxed:itstartsandendsautomatically.
Theheatsensor,intheheater,detectstheame’sheatandlightstheredLEDto
signal that the device has started.
All functions are controlled electronically. The fuel pump and combustion air blower
arefullystabilisedagainstvoltageuctuations,whichensurescleancombustion,
regardless of changes in the battery voltage.
Theheaterisequippedwithbuilt-inoverheatprotection,whichcutsthefuelfeedif
the device overheats.
When the heater is switched off, it cools down automatically. The cooling function
ventilatestheburner,anddischargestheue-gasesgeneratedduringtheswitch-
off, to the outside of the cottage.

Installation
Things to note during installation
Basic installation methods
The most common installation method is a wall lead-through. Installation kit 4880
andaue-gasexhausthead4004 have been used in the installation. In addition,
the fuel tank 4030 (30 l) has been installed in the base housing 4031.
Flueinstallation.Thisinstallationmethodrequiresthebuilding’schimneytohave
oneueavailable.Theuemustnotbeconnectedtootherreplacesorequip-
ment. Installation kit 4880isrequiredfortheinstallation.Intheexampleinthe
picture, the fuel is fed from the fuel tank 4130(130l)undertheoor.
Things to note when selecting the installation location
When selecting the installation location and method, note the following:
• If you choose the wall lead-though method, install the device on a wall where
thewindpressuredoesnotdirectlyimpingetheue-gasexhausthead.When
the device is running on low power, wind pressure can snuff out the burner
ame.Theburnerwillalsogeneratemorescaleduetochangesinwindpres-
sure.
• The length of the control panel wire is 3 m. Do not install the device near to an
external door or a window, because the temperature changes in these loca-
tions are too great. The control panel contains a thermostat sensor.
• Flue installation will slightly increase the generation of burner scale.
• Avoid making the fuel and electrical lines that lead to the device excessively
long.
• The device must be positioned so that it is protected from water drips, spills or
splashes.
When installing the device, bear in mind that may be necessary to detach the
device for maintenance. Therefore, it is advisable to make the connections easy
to open and disconnect. The device does not need to be detached to clean the
burner.
The heater should be installed on the level. The inclination must not exceed 5°.
While the device should not breakdown, if it is temporarily tilted at a steep angle
(even for some hours), the burner will not yield the optimal performance, if it is
continuously inclined.
Also, consider where you place the control panel, as the length of the control
panel’s cable may pose some limitations.
Avoid installing the control panel in the immediate vicinity of a water outlet.
If possible, install the control panel on a vertical surface.
We recommend that the device be installed by an authorised Wallas service shop.

Installation
Protection of pipes, hoses and cables
Power cables and fuel hoses must be protected in locations where they are sus-
ceptible to mechanical damage due to sharp edges or heat.
Safety distances
Distance from surrounding walls. Observecountry-specicrequirements.
There must be enough clear-
ance between the wall and
the device so that the space
can be kept clean and free of
dust, litter and other unwanted
objects. The openings for the
air intake, in the lower section
of the device’s casing, must be
unobstructed.
There must be no surfaces,
structures or objects that are
ammableorcanobstructthe
heat, within 1 m above the
device’s upper surface.
Safety distances
Device over 1300 m above sea level
If the device is installed over 1300 m above sea level, a short circuit connector to
activate the mountain switch has to be added into a connector J14 of the device’s
circuit board. The connector is in the accessory bag.
Do not remove the jumper (or change its location) from the device’s circuit board.
Always use original Wallas accessories and parts with Wallas equip-
ment.

Instructions for wall lead-through installation
Accessories 4004 and 4880arerequiredfortheinstallation.
Note that different measurements for insulation are given for Finland, as opposed
to Sweden and Norway, due to different national regulations.
10. Drill or cut an opening in the wall for
• the exhaust pipe and its insulation (ø 120 mm, Finland – ø 320 mm, Sweden
and Norway). Note the different measurements for models 26CC and 40CC.
• the combustion air intake pipe (ø 50 mm). The cover plate (16) can be used
as a stencil.
11. Cut both pipes (18 and 21), so that the pipes extend from the wall ca. 40 - 45
mm (23 and 24) when the pipes have been pushed all the way in the heater
connection pipes (25 and 26) and the heater is positioned at least 70 mm (Fin-
land) / 100 mm (Sweden and Norway) from the wall.
12. Install the cover plates (16 ja 17) on the lead-through openings and seal the
connection between the wall and the plate with silicone paste.
13. Push the pipes (18 and 21) all the way into the connection pipes (25 and 26)
and seal the exhaust pipe’s connection (25) with a pipe clamp (11) and the
combustion air pipe’s connection (26) with a hose binder (10). (Both ties can be
found in the heater accessory bag.) The exhaust pipe cannot be tightened suf-
cientlybyanyotherfasteningthanapipeclamp(11),whichmustbetightened
sufcientlytolockthepipeinplace.
14. Place mineral wool (19) on the exhaust pipe (18) so that the insulating material
extends from the back surface of the heater to ca. 10 mm outside the wall (27).
Place the insulation mantel plate (20) on the insulation.
15. Then, push the heater to a distance of 70 / 100 mm from the wall, while guiding
the hoses and the insulation through the lead-through openings.

Jointing
A jointing should only be made in long
power cords, if necessary, in which
case the cord must be replaced with
a thicker one. The jointing cannot be
further than 1 meter from the device.
Electrical connections
Things to note about the connections
The device uses 12 V direct current voltage. To minimise current losses, make the
power cable as short as possible and avoid jointing. The cross-sectional area of the
cable is dependent on the length of the power cord. The cross-sectional area of the
cable must be consistent all the way from the stove to the battery. The maximum
length of the power cord is 10 m.
Electrical connections of the device
12 V direct current system
Connect the red wire of the power cord to the plus terminal of the battery and the
black or blue wire to the minus terminal. A 15 A main fuse must be installed near
the battery on the red plus wire of the power cord.
Checking the connection
The device consumes most power when it is started up (glowing). At this point volt-
age losses are also at their highest. During the glowing phase, the voltage must be
atleast10.7Vmeasuredatthequickcoupling.Ifthevoltageislowerthanthis,the
device may not start.

Fuel connections
Things to note about the connections
The standard length of the fuel hose is 4 m (max 6 m). Cut the fuel hose to a length
suitable for installation.
The lift height of the pump should be less than 2 m; preferably 0.5–1 m.
Thefuelpipemustalwayshavealter.
Country-specic requirements
Thestandardfuelhoseisplastic.Pleaseobservethecountry-specicrequire-
mentswithregardtothematerialforthefuelhose/pipe,thefuellterandthehose
clamps.Theinnerdiameterofanewreplacementhosemustbeequaltotheinner
diameter of the plastic hose.
Copperpipeandmetalltersareavailableasaccessories.
Fuel feed
If the lift height is outside the recommended 0.5–1 m, the fuel feed must be
checked and, if necessary, adjusted. The fuel feed must also always be checked,
if parts of the fuel system, such as the pump or the electronics card, have been
replaced.
Fuelsystemadjustmentsaredevicespecic.Werecommendthattheadjustment
be carried out by an authorised service shop.
Tank placement
1. The fuel tank should always be placed below the base of the device. (The fuel
surface level must be below the device.) When the fuel level is above the base,
the solenoid valve 30017 must be installed on the tank-side end of the hose.
2. The fuel tank can be placed in the base housing 4031, or outside it, for exam-
ple, in the foundations of the house or a suitable protective box. Protect the
tank and the fuel hose from direct sunlight.
3. The fuel hose lead-through must be shielded by a metal cover pipe.
4. The standard length of the fuel hose is 4 m. It can be extended with a 2 m ex-
tension hose, which gives a total length of 6 m. Connect the hoses with bayo-
net couplings, which are twisted together.

Fuel
Several different types of fuel can be used in the heater.
When selecting the fuel type, take note of the temperature limits of each particular
fuel.Thelimitvaluesprovidedherearetobetreatedasguidelines.Conrmthe
actual temperature limits from the fuel supplier.
• light furnace oil / diesel, summer grade, temperature must not fall below –5 °C
• light furnace oil / diesel, winter grade, temperature must not fall below –24 °C
• light furnace oil / diesel, arctic winter grade, temperature must not fall below
–40 °C
• parafn,theoperatingtemperaturemustnotfallbelow-40°C
Ifthetemperaturedropslowerthantheminimumlevel,parafnmayforminthe
fuel.Thismayresultinthefuellterandpumpbeingclogged.Theclogwilldissolve
only if the fuel temperature rises clearly over 0 °C.
Inwinterconditions,arcticwintergradeorparafnmustbeused.
The less aromatic substances the fuel contains, the less deposits will be formed.
Normal furnace oils contain ca. 35–40 % aromatic substances. In coloured city
diesels (e.g. Tempera 3G and 5G) and green furnace oils the concentration is 20
%.Sinceparafncontains0.5%aromaticsubstances,itgeneratespracticallyno
scale when burning.
Conrm the actual temperature limits for the fuel you are using
from the fuel supplier.

reached.
The sun-switch shuts down the device automatically, if the temperature rises above
therequestedtemperature,forexample,duetosunlight.Thetemperaturemust
rise by +3 °C above the set value for a half an hour. If the device has been shut
down by the sun-switch, an indicator light (5) blinks on the thermostat. The sun-
switch can be turned off temporarily, by turning the temperature control (2).
A device that has been shut down can be restarted manually, if necessary.
Conservation temperature: the temperature control (2) is set to minimum, and the
room is maintained at a temperature of +2–+8 °C. The sun-switch is not enabled in
this mode.
Alternative use
The power is adjusted manually.
To enable this function, turn the power adjuster (2) to positions min - max - min
- max within 10 seconds of the yellow indicator (4) lighting up, during the device
start-up.
The device signals that the function has been activated by blinking the thermostat
indicator light (5) three times.
You can check whether or not the function is in use by turning the power adjuster
(2): the thermostat indicator light should not light up at any point.

Operation
After installation or maintenance, if the fuel line is empty, the device
may not start at the rst attempt. If this is the case, the red combus-
tion indicator light will start to blink roughly 4.5 minutes after start-
up.
Press the power switch to the OFF position. The device cannot be
restarted until the cooling phase has completed.
When it has cooled, switch the device on again.
If the device does not start after two attempts, it cannot be started
again: the device will lock down (lights blink to indicate this).
Release the lock (instructions in the maintenance section)
Depending on the length of the fuel hose, the device may have to be
started up several times. Keep an eye on how the fuel travels in the
fuel hose while starting up the device.
First start-up
After the heater has been started up, the power can be adjusted step-less with
the power adjustment knob (2). Avoid turning the adjustment knob back and forth
rapidly, as this can cause the burner to become sooty.
To end manual operation, turn the device off and restart it after allowing it to cool
normally.
Shutdown
You can shut down the heater by pressing the power switch (3) in continuously for
at least 2 seconds. The yellow current indicator light (4) will go out immediately.
Theredcombustionindicatorlight(1)willcontinuetoblinkforca.veminutes,
while the device is cooling down. You cannot restart the device until the combustion
light has stopped blinking.
Remote control
The device can be controlled manually with an accessory, which can be purchased
separately.
If the device is started using the remote control, the orange indicator light (5) on the
control panel will blink at 10-second intervals. The sun-switch is not enabled in this
mode.
Do not start the device, while the battery is being recharged from a
generator unit or a battery charger (risk of overvoltage).
Cleaning and maintaining the device
To keep the device easy to use and looking good, clean it regularly. Wipe the de-
vice with a moist cloth and dry it with another cloth. Do not use abrasive cleaning
sponges or agents. Also, avoid chemically strong cleaning agents.
Regularly vacuum the back of the device. Dust easily collects at the back of the
device,andtheairowcreatedbythedevicewillspreadthedustallovertheroom.
ObservethegeneralmaintenancerecommendationsforWallasequipmentwhen
servicing the electronic and mechanical parts of the heater.
Never use the main switch to cut the power before the cooling
phase, which starts after device is turned off, is completed.

Special recommendations
• When selecting the fuel type, take note of the temperature limits of each par-
ticular fuel.
• Onlydiesel,lightfurnaceoilorparafncanbeusedinWallasdiesel-operated
products.
Removal of water from the tank (1)
• During the period of use, add isopropyl alcohol-based (not ethyl or methyl
based) anti-freeze for petrol vehicles (carburettor spirit) to the fuel. The agent
shouldbeaddedafterthetankhasbeenemptied,andrelled,afewtimes,
and always at the beginning and end of an operating season. The anti-freezing
agent binds the water in the fuel and prevents the fuel from settling and spoil-
ing during the summer season. For the dosage, observe the recommendations
provided by the manufacturer of the agent.
Maintenance
An anti-freezing agent for diesel vehicles may increase the forming
of scale at the bottom of the burner and therefore shorten the mainte-
nance interval.
