Operation description
Wallas Water heater is designed especially for water circulation heating systems outside of the electricity network.
Light furnace oil, diesel oil or paraffin can be used to fuel the device. 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 completely enclosed, and balanced with the
flue-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 fixed: it starts and ends automatically.
All functions are controlled electronically. The fuel pump and combustion air blower are fully stabilised against voltage
fluctuations, 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 flue-gases generated during the switch-off, to outside.

Things to note before Installation
Heater installation
Country specific regulations shall be followed in any installation. The warranty of products is valid only in installations
that are done according to this manual. Wallas recommends that the device be installed by an authorized Wallas
service shop or professional installer.
Selecting the installation location
The device shall be installed into a dry space in a protected location. The device must be mounted to a solid surface.
When installing, please note that the device needs to be removable for servicing. Connections and location should be
made so that the device can be easily disconnected for removal.
The heater should be installed vertically level when the boat is on an even keel. The static inclination must not exceed
5°. While the device will tolerate being temporarily tilted to a steep angle (even for some hours), the burner will not yield
optimal performance if it is constantly inclined.
Select the place of installation to allow a minimum amount of bending in the hoses / ducting. Avoid installing the heater
and control panel in the immediate vicinity of any potential water intrusion. If possible, install the control panel on a
vertical surface.
Installation of pipes, hoses and cables
Power cables, water and fuel hoses must be protected in locations where they are susceptible to mechanical damage
due to sharp edges or heat. All cables and hoses should have a fluid precluding "drip loop" to prevent water or other
fluids from following wires or hoses to the heater. All cables should be strained.
Installation of valves
A separate mixing valve must be installed to the hot water line if Wallas on-demand hot water accumulator is used
because Wallas on-demand hot water accumulator doesn't have a mixing valve built-in.
Installation space
The device can be installed within the heated space or outside of it. The device should be protected from rain and
splash water.
It's forbidden to install the heater to a space which may contain gasoline fumes!
When designing or installing the system, make sure that any possible leakage points (joints, the whole heater
and the expansion tank) are installed in such a place that the possible leaks cannot destroy anything. It is
recommended to build a spill reservoir which can hold the coolant used in the system.
Following sections of manual are presenting important basic installation information but if you have any questions
please be free to contact purchasing/local distributor point for more information.

Do not over radiate the system.
If the temperature of the coolant does not rise to the target temperature, the built coolant system is over radiating. This
means that there is a risk of condensation in the burner. Condensation water may cause soot and caulking into the
burner / heat exchanger.
Signs of the over radiation:
Coolant never reaches the target temperature and the heater power has remained 100%. E.g. target 55 °C
coolant temperature have raised to 45 °C but does not rise from that.
Exhaust leadthrough drips water
To prevent the over radiation:
Use 55 °C / 131 F normally-open-switches (thermostats) in matrix heater's fan motor power wire. It also saves power
when the fans do not run unpurposely when the coolant is not warm enough to heat the room.
Example of the normally-open-switch (thermostat) Installation example
Thermostats for the matrix heaters
Wallas room thermostat 2422 can be used to control the matrix heaters. Room thermostat switches the matrix heater
fans ON when needed.
Select the location of the room thermostat from the wall of the room, where the temperature is desired to be measured.
Do not install close to heat source or close to a window or door. Avoid locations that might be contacted by direct
sunlight.
Example of the room thermostat Electrical connections

Fastening the devices
Floor mounting
The heater can be installed to the floor by using
"legs". Secure the device to a flat stable
surface which is not tilted more than 5 degrees
from the horizontal plane. While the device
might not break if it is temporarily tilted to a
steep angle (even for some hours) the burner
will not yield optimal performance if it is
constantly inclined. The "legs" and necessary
screws can be found from the accessory bag.
The heater (Spartan water or Viking water)
must be well fastened to withstand heeling of
vessel in all directions.
.
Ensure that there is enough space for the exhaust hose installation above the heater.

General electrical connections
Safety instructions for wiring the heater
Make sure that electrical cables are not damaged. Avoid: chafing, kinking, jamming or exposure to heat.
Electrical connections and ground connections must be free of corrosion and firmly connected.
Things to note about the connections
All connections must be arranged in the craft so that they can function perfectly under normal operating conditions.
Insulate unused cable ends.
The device uses 12 V (nominal) direct current voltage. To minimize current losses, make the power cable as short as
possible and avoid joining. The cross-sectional area of the cable is dependent on the length of the power cords. The
cross-sectional area of the cable should be consistent all the way from the device to the battery. The maximum length
of the power cord is 10 m, based on 6 AWG cable.
The cross-sectional area of the cable
Total length of the power cord (m) Minimum cross-sectional area of the cable in square mm (US
Gauge)
0-4 2,5 (13 or 12 AWG)
4-6 6 (9 or 8 AWG)
6-10 10 (7 or 6 AWG)
If a thicker cable is required, make a separate joint in the power cord. See picture "Electrical connections of the
device".

- 11 -
Product specific electrical connections
Electrical connections from power system
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. See picture
above.
24 V direct current system
If the device is to receive power from a 24 V system, always connect a charging voltage reducer through a 12 V battery
before connecting the device as shown above.
Without the battery most voltage voltage reducers will not be enough to generate the large amount of current the glow
plug requires.
After the 12 V battery, the connection is the same as in a 12 V system. Note, if using remote wire, the remote wire also
needs connection to 12V, not 24V.
For DC DC 24/12 converter ask recommendation from your local dealer. There are major differences between them,
but typically a converter rated for 25A is required.
Checking the connection
The device consumes the most power when it is starting (glow on). At this time, voltagedrop is at it's highest. During the
glowing phase, the voltage must not fall below 11 V measured at the quick coupling. See picture above. If the voltage is
lower than this, the device may not start.
All wires should to be mounted with smooth bending and equipped with strain relief.

Connection alternatives (optional)
A wireless thermo sensor (4432) can be connected to the
heater. The wireless thermostat is the most accurate
sensor and portable.
If the heater does not have any sensors connected, then
room temperature monitoring is not available.
Power loss sensing & shutdown
If the heater is needed to be protected from the accidental main switch cutoff while unit is still running it can be done
following way.
Locate the blue Enable wire loop what is connected to
bottom of the heater.
Cut the 2nd wire nearby connector and connect it to main
switch +12V pole.
The blue wire should connect to the red +12V lead coming
from the controlled side of the boat's main battery switch.
If the main boat switch is opened (turned off) while the
heater is running, the heater will initiate a controlled or
"normal" shutdown. Re-closing the main battery switch will
not re-start the heater. Re-start must be initiated by the
user at the panel or via mobile device from Wallas Remote
application.

- 13 -
Coolant connections
All water heating components must be installed in safe locations, where they do not cause any scalding or damage to
people, animals, or surrounding materials due to excessive heat. Especially metal joints can get as hot as the coolant
(max +85 °C) and can cause damage if they are positioned too close to less heat-resistant materials.
Before doing any installation or service work for the heater or water system, shut down the heater and let the system
cool down to prevent possible injury or burns.
When choosing the installation location, it should be noted that in the event of a possible leak, the
leaking water will not enter the boat/vehicle/building structures.
There must be an overflow basin or an outlet pipe in the installation space of the device.
Spring clamp must be used in every hose barb connection.
Make sure that the flow direction is correct in your installation.
Route all the coolant hoses so that they are rising from the lowest point to higher. This will prevent air locks from the
system.
Follow the hose manufacturer's bending radius recommendations to prevent clogging or kinking.
Make sure that the coolant hoses are far enough from the hot places such as engine/stoves/heaters/fireplaces.
Coolant ducting and fuel hoses must be protected in locations where they are susceptible to mechanical damage due to
sharp edges, chafing or heat.
Double check all the hose clamps and joints to prevent any leakages.
Make sure that the temperature difference between the inlet and outlet of the coolant is approximately 10 Celsius. This
ensures that the water flow through the whole system is sufficient.
The heater is designed to be used with the open header tank. The system should not be pressurized. The maximum
pressure of the system 0,5 bar.
To prevent corrosion and freezing, the system has to contain enough antifreeze/coolant liquid following the coolant
manufacturer's recommendations.
Before first start up, or after liquid change, it is important to bleed the coolant system of air. If the system is not free of
air, the system will not work as designed.
When choosing the size of a header tank make sure that volume of the tank is large enough. In coolant systems using
19 mm hose, for every 10 m of hose, a 64 °C temperature change will change coolant volume by 4 cl. In coolant
systems using 21 mm hose, for every 10 m of hose, a 64 °C temperature change will change coolant volume by 5 cl.
Maximum height difference for Wallas (7116) 5W circulation pump is 1,4 m and it will pump max 8.5 l/min.
Maximum height difference for Wallas (7117) 15W circulation pump is 3,2 m and it will pump max 12,6 l/min.
Water pump installation
The water pump must be installed
horizontally.
When tightening the connector, use two 21 mm
wrench, ViceGrip® or equivalent to tighten the
joint.
Arrow printed to the side of the
pump indicates the flow direction.

Bleeding and filling system with coolant
It is easiest to fill ducting starting from the lowest point of installation. If you start filling from the header tank there
will be airlocks. Filling from the lowest point takes most of the air out from the system, so this makes bleeding much
easier. If there is air in the ducting heater does not work correctly.
Premix enough coolant according to manufacturers instructions ( Standard recommendation is 30% antifreeze, 70%
water in Finland)
Install T-branch to the lowest point of coolant ducting

8. Coolant Feeding Tank
Coolant system needs to bleed from air
before starting the heater. Never use
heater without coolant.
Have hose closing pliers ready for feeding the coolant.
1. Connect the vacuum pump to the expansion tank’s over bleeding hose.
2. Check that Valve 7 is open.
3. Squeeze the hose with the pliers B to prevent the coolant from flowing from this direction.
4. Gently pump the vacuum pump a couple of times. Listen when the coolant begins to flow to the heater.
5. Continue to pump the vacuum pump a couple of pumpings at the time as long as you see the coolant in the
expansion tank. Note! Too high under pressure / vacuum (too many pumpings at the time) may cause
deforming of the heat exchanger.
6. When you see that the coolant is in the expansion tank, close the pliers A. Then open pliers B.
7. Keep on pumping the vacuum pump until you can see that no bubbles are coming from the line to the expansion
tank.
8. Close the valve (7) in the feeding tank.
9. Open the pliers A.
10. Remove the vacuum pump and make sure the coolant surface does not drop too low in the expansion tank.
Coolant expands 5% when the temperature changes 60 °C.
If you have more than 50 liter coolant in the system, you will need higher volume expansion tank or
buffer tank (standard expansion tank volume is 3 liters).

Exhaust gas connections coaxial
Exhaust gas lead-throughs
It is important to choose right part for right purpose. Coaxial exhaust gas lead-throughs 2467,5300 and 5400 are
recommended for Wallas unit. The ø 28/45 mm lead-throughs fit the exhaust gas hose 2448, providing maximum wind
tolerance. All exhaust gas lead-throughs are stainless steel.
The exhaust gas tube reaches a high temperature! Be sure that the tube does not touch flammable materials and
double check the connections. Insulation sock 1030 is available as an accessory.
Safety distances
Location
Air must always flow freely past the lead-through. Install the lead-through
on a flat surface.
Avoid corners or recessions where wind pressure can disturb the
functioning of the device.
The minimum distance of the lead-through from the fuel tank’s filler hole is
400 mm (16”).
The minimum distance of the side lead-through from the surface of the
water is 500 mm (20”). Especially in sail boats it should be noted that the
lead-through must never be submerged.
It is recommended to place the lead-through in the side as far back as
possible or directly in the transom.
Never place lead through near cabin fresh air intake. Make sure that
exhaust gases can never mix into fresh air intake.
Goose neck Installation
When preparing the installation cut-out for the lead-through, it is a good
idea to use the lead-through as a model for the cut-out; especially if the
lead-through is circular.
If necessary, seal the installation cut-out with silicone in addition to the lead
through seal. Note! Do not use silicone on a wooden boat.
The side lead-through must always be equipped with a so-called goose
neck section. The goose neck will effectively prevent splash water from
getting to the device. The highest point of the goose neck must always be
above the surface of the water.
The device will go out, if the exhaust gas lead-through is submerged.
Other things to note
Exhaust gas is hot. Always ensure that there is nothing that is susceptible
to heat damage within 200 mm (8”) of the effective area of the exhaust
gases (e.g. ropes, fenders or the side of another boat).
All lead-throughs raise the temperature of their surroundings.
A wooden deck, in particular, may dry due to the heat. Remember that the
surface of the lead-through is hot during use.
An exhaust gas tube with a length of more than 2 meters (7’) has to be
equipped with a drainage lock 2471 (condense water) located to the lowest
point of the tube.
The exhaust gas pipe must be made of stainless steel. If necessary, seal
the connections between the exhaust gas pipe and the lead through with
heat-resistant silicone.
When installing the lead-through to the stern side or to otherwise leaning
position, be sure that the water do not stuck the exhaust. Drill app. 2 mm
(3/32”) hole to the lead-through or to the exhaust pipe.
Heater takes makeup air for burner around the exhaust pipe. When 1030 insulation sock is used it's mandatory to leave
space between heater and insulation sock to make intake air flow possible.
