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.

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.

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.

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

Hose installation instructions

1. Open Expansion Tank 2. Over Bleeding Hose 3. Vacuum Pump 4. Pump 5. Pliers A 6. Pliers B 7. Valve 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 Goose neck

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.

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.

Closable lead-through 2460 (Viking water only)
Assembly and detaching instructions Closable lead-through 2460

Maintenance To keep the seals from hardening, lubricate them yearly with a heat-resistant petroleum jelly.
The cap of the closable lead-through must be detached for installation and seal maintenance by pressing the spring indicated by the arrow in with, for instance, a screwdriver. Take care not to let the screwdriver slip as the spring is very stiff. Hold the cap with your other hand when pressing in the spring. When the spring is down, pull the cap gently out of the frame. When assembling the lead-through, ensure that the order of the parts is correct. Also make sure that the spring goes in the correct hole in the cap. Otherwise, the lead-through cannot be closed.

Check that closable fitting is open before starting the device.

Side lead-through 2467
Assembly instructions A side lead-through is installed in the side of the boat or in the transom. In sailboats it is recommended to install it in the transom. The installation always requires a so-called goose neck. Make the necessary installation cut-outs and spread a suitable sealing agent on both sides of the seal and on the screw holes. This will ensure that the connection is waterproof.

Fuel connections

The standard length of the supplied fuel hose is 4 m (max 8 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 Wallas filter, either in-line or in the fuel tank. Only one filter should ever be in the system. The fuel filter can be installed either near the device, near the tank, or in another location where it can be easily checked and replaced, when necessary.
Diesel engine fuel filters and/or separators are not approved for use. All soft connections should be made with rubber or silicone hose which is resistant to fuel. When joining with rubber connectors, tubing ends should butt against each other.
Fuel lines other than those supplied by Wallas should be small bore (2-3mm) and must be qualified for suction use. Typical rubber fuel hose is not qualified for suction use, having a soft, collapsing inner wall lining. Please contact your Wallas dealer/distributor if non-standard fuel lines are being considered.

Connection to a heater

1. Pump inlet elbow 2. Fuel line nut 3. Use pliers to hold the pump inlet elbow steady 4. Tighten the 12 mm fuel line nut. Tightening torque is 19 Nm (14 ft/lbs)
Note! The joint has to be very tight to prevent air leaks.

Country-specific requirements
The standard fuel hose is plastic. Please observe country-specific requirements with regard to the material of the fuel hose/pipe and the fuel filter. The inner diameter of a new replacement hose should be equal to the inner diameter of the plastic hose. Copper pipe 300692 and metal filters 30016 are available as accessories. Ask local requirements from your distributor.
Fuel feed
If the lift height exceeds 2 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 specific. These adjustments should only be carried out by an authorized service shop.
Connection to a fixed tank supplying other diesel consumers
The Wallas device must have a dedicated (not shared) connection with a fuel filter outside the tank.
Connection to a separate tank
Cap run-throughs and sintered in-tank filters are used on plastic tanks. The fuel tank should be mounted securely.

Fixed tank connection 30011
Installation instructions for tank connection 30011
1. You will need to make a Ø 25 mm (1″) hole in the upper surface of the fuel tank. Choose the location of the hole so that when the fuel tank tilts the end of the intake pipe will stay in the fuel even if the tank is not full. If the end of the intake pipe does not reach the fuel, the device will quickly choke on the air in the fuel system and that can cause malfunction to the system. 2. Cut the fuel intake pipe (Ø 3.2/0.8 mm) to the appropriate length. The end of the pipe must not touch the bottom of the tank in order to keep water and sediment from the system. It is recommended to cut the pipe short enough to leave the engine intake pipe at a lower level. This way the device cannot empty the tank. 3. Install the pipe straight end first and angle the two “ears” at the bottom of the threaded barrel inside the hole and then align the threaded barrel vertically so the ears are hooked on the underside of the tank top. Carefully slip the rubber washer over the bent pipe end and over the threaded barrel, followed by the metal washer and the nut. Thread the nut to the threaded barrel and tighten, sealing the fitting to the top surface of the tank.
If the device uses the main tank of the boat, note that the device cannot take the fuel from the same fuel output line as the engine of the boat.

Solenoid valve 30012
The solenoid valve 30012 (available as accessory) prevents the tank from emptying in case the fuel system fails. The fuel filter should be installed before the solenoid valve. Our recommendations in the following installation configurations:
Preferred installation layout (solenoid valve 30012 is not required)
1. Fuel level is below the heater/stove. See figure 1. · No special accessories required
Solenoid valve 30012 is recommended
2. Fuel level may temporarily rise above the heater/stove (e.g. in the fuel tank filler pipe or when the boat tilts). See figure 2. · No special accessories required but solenoid valve 30012 is recommended.
Less desirable installation arrangement (solenoid valve 30012 must be installed)
3. Fuel level is above the heater/stove. See figure 3. · Less desirable installation arrangement · Possible siphon problem · Solenoid valve 30012 must be installed in the fuel hose near the tank.
If the fuel level in the tank is above the device, a solenoid valve 30012 must be installed in the fuel line immediately after the tank lead-through.

Tank external filters 30015, 30016
Assembly instructions
Filters can be installed in a ø 5 or ø 6 mm plastic tubing or 1/8″ metal pipe. Ensure that the fuel pipes are clean before installing the filter. There must be no debris or impurities between the pump and the filter as they will clog the pump. The filter type must be selected according to the operating conditions and country-specific requirements.
Air bubble

Fuel filter 30015 Fuel filter 30016 (accessory)

The filter is supplied with the device.
The filter can be installed directly in the 30011 tank connection by using a ø 6 mm rubber hose (1) and 10 mm hose binders (2). Alternatively, the filter can be installed between two ø 5 mm fuel hoses with ø 5 mm rubber hose (3) and ø 8 mm hose binders (4).
Install the filter in the direction of the arrow on it.

This filter is used in countries where a metallic fuel transfer system is required. A 1/8″ metal pipe is used for the installation.

Selecting the fuel
When selecting the fuel type, pay attention to the temperature limits of each particular fuel. The limit values provided here are to be treated as guidelines. Confirm the actual temperature limits from your local fuel supplier.
HVO-Diesel, Diesel, summer grade, temperature must not fall below -5 °C. HVO- Diesel, Diesel, winter grade, temperature must not fall below -24 °C. Diesel, arctic winter grade, temperature must not fall below -40 °C. If the temperature drops lower than the minimum level, paraffin may form in the fuel. This may result in the fuel filter and pump being clogged. The clog will dissolve only if the fuel temperature rises clearly over 0 °C. For fuel additives and life length of the fuel ask information from your fuel supplier.
Recommended fuels As one of the leaders in ultra-low-emission burner technology, Wallas is committed to clean combustion processes. With our laminar flow Green Boost burner technology and adaptive software, our burners have ultra-low emissions, including exceptionally low CO2 and NOx levels. All Wallas-Marin diesel heaters and stoves use diesel, renewable diesels (HVO 15940), or paraffin oil (kerosene) as fuel. These include: Today’s road and boat diesels (EN590), renewable (HVO 15940). We don´t recommend the use of FAME (Fatty Acid Methyl Esters) fuels. The methyl esters in biodiesel are hygroscopic. This means that they can absorb considerably more moisture than petroleum-derived diesel and hold this in suspension in the fuel. Petroleum- derived fuels absorb considerably less moisture by comparison and tend to shed water as a separate layer at the bottom of storage tanks. When water is able to contaminate diesel, it provides conditions suitable for microbial growth and can lead to diesel bugs, molds, yeasts and bacteria spreading throughout the fuel. FAME is bio-degradable and is an ideal source of nutrients for microbes. If contamination is left untreated, it can damage the fuel permanently.

Device operation

Ignition
The start-up process and heating is automated.
The heater will ignite when the heater’s Start/Stop Icon is selected and you confirm the selection by holding the Select Button down for 3 seconds. “Starting” will appear on the screen, indicating that the heater is on and in its Starting mode.
The light orange combustion light will light up when the burner flame has been ignited and the combustion has stabilized (after about 5 min). Heater will be fully operational about 10 minutes later. About 12 minutes after first giving the start command, the system controls will be handed over to the user, signaling the end of the Start sequence.

First start-up
After installation or maintenance, if the fuel line is empty, the heater may not start at the first attempt. Start-up phase with empty fuel line may be longer than normal and might take up to 15 minutes. If the heater does not ignite, the orange combustion light will not appear and error information is shown. The heater will shut down after the cooling phase completes. The device cannot be restarted until the cooling phase is completed. When the cooling phase is finished, switch the heater on again.

Lock out
If the device does not start after two attempts, the heater will lock itself, preventing re-start, and lock icon will appear. Investigate, find and follow error solving instructions to resolve the problem prior to further use. After resolving the problem, remove the lock (instructions in the control panel section) and start the unit. Depending on the length of the fuel hose, the heater may have to be started several times during priming. Observe how the fuel moves in the fuel hose while starting up the heater. Fuel should move about 15mm (5/8″) each time the fuel pump clicks, and should not fall back toward the tank between clicks. If fuel motion is weak or falls backward, check the fuel nut at the pump for tightness and tighten if needed. Tightening torque is 19 Nm.

Adjusting the heat (coolant)
Coolant target temperature can be adjusted between 55 – 85 °C (131 F – 185 F). Instructions how to set the target coolant temperature are explained in the Control Panel section in detail. Preferred temperature units (Celsius or Fahrenheit) can be selected from Control Panel (Settings – Temp Unit).
Wallas Spartan Water/Viking Water has automatic temperature control for coolant. Target coolant temperature will be maintained automatically, through power level changes and pausing when necessary.
Heater temperature control will estimate temperature change over ten (10) minutes to optimize heat output to the water.

Adjusting the hot water
Hot water target temperature (if cylinder stat is connected) can be adjusted between 30 – 80 °C ( 86 F – 176 F).
Note following situations where the system will give a warning to the user:

Situation
Hot water target temperature is set to 54 °C or below
Hot water target temperature is set higher than the coolant target temperature

Warning
Risk of legionella bacteria
Hot water target should not be set higher than coolant target

– 31 –

Pause feature (Thermo Mode only)
Coolant target temperature can be adjusted between 55 – 85 °C (131 F – 185 F).
The pause feature automatically turns the heater to pause if the coolant target temperature is exceeded by +10 °C (18 F). The unit will start heating again when the coolant temperature drops 10 °C (18 F) from the target temperature. Heater will attempt to maintain the target coolant temperature.
For example if the coolant temperature is set to 70 °C (158 F) then the heater will go to Pause mode when the temperature rises to 81 °C (178 F). The unit will start heating again when the temperature drops to 59 °C (138 F).
If the heater is in Pause mode, “Paused” will appear on the screen. During pause, the fuel pump stops and the system runs a normal cool down period and then goes silent. In summertime mode heater is started when hot water accumulator temperature drops under the set target coolant temperature.
Summertime feature (hot water tank/calorifier)
Summertime feature can be selected (On/Off) from the Control Panel (settings).
When the summertime feature is not selected (Off) and there is a commercial hot water accumulator in the system, the pause mode will be controlled by coolant target temperature as explained in the earlier chapter.
When the summertime feature is selected (On) and there is a commercial hot water accumulator in the system the heater will go to pause mode when the coolant target temperature is exceeded by +10 °C (18 F) and it starts heating when the hot water temperature drops below the target temperature.
Example:

Installation check list
Installation check list before test-run
Installation
· Read manual and use only official Wallas parts. · Ensure that the boat/cottage/location is sufficiently ventilated. · Ensure sufficient air ventilation for heater, minimum aperture of 100 cm² (16 sq.in.) into installation area. · In boat heaters the exhaust pipe outlet must be at least 400mm(16″) away from the opening for filling fuel or tank breather. · We recommend installing the control panel on a vertical surface where liquids are not able to leak into the switch and it is out of reach of children.
Fuel system
· Fuel for the device comes through a separate tank fitting, not via a manifold or connection shared by the engine or other device. · Install the filter to the fuel hose before you install the device, in an accessible location for filter changes. · Fasten the fuel hose couplings tightly. Always use a sleeve joint on the hose (olive ring). · Make sure that the surfaces of the couplings are clean before fastening them. · The hoses must be kept clean during installation. · If the surface of the fuel tank is above the device, a magnetic valve must be installed into the fuel hose close to the tank. · Cut the fuel hoses to the appropriate length when installing them.
Electrical installation
· The nominal voltage of the device is 12 VDC. · Current for the device is taken directly from the battery terminals using cables that are as short as possible. · Put the main fuse of c. 15 A on the + cable close to the battery.
Exhaust fumes
· When choosing the outlet location, note that exhaust fumes are hot. · In boat heaters use a goose-neck in exhaust pipe to prevent splash water entering. · If your installation location is a boat with metal hull, the device and outlet must be insulated from the hull to prevent electrochemical corrosion. · The exhaust pipe must not come into contact with combustible materials. Insulate the exhaust hose, if necessary.
Warm coolant hosing
· Flow direction is correct · All hoses are rising from the lowest point to higher (if not possible then use bleeding valves) · There are no leakages in the system · Header tank is large enough · System contains enough coolant to prevent freezing · System is bleed correctly · Hoses are coolant resistant material
– 48 –

Water hosing · Accumulator tank is installed if necessary · Mixing valve must be installed if Wallas on-demand hot water accumulator is used · Fresh water maximum usage pressure is 3 bar. Do not attach to water supply network without pressure reducer. · Use purposed hot and cold fresh water pipes/hoses only Initial start-up · The device usually does not start the first time after it has been installed. It may take several starts (c. 4-6) for the fuel hoses to fill up enough for the fuel to reach the burner. · Watch the hoses as they fill up as you start the device. · After two unsuccessful start-ups, the device will lock. · Follow the instructions for unlocking the device and try again. · When the device starts, look for possible leaks in the exhaust and fuel connections. · Run the device for c. ½ hour to allow possible installation and manufacturing greases to burn off. Make sure there is enough ventilation.
Remember to carefully read the instructions for installing, operating and servicing each device before installation.

Maintenance recommendations
Service recommendation for the heater is 2000 operating hours or every 3 years, whichever comes first.
Maintenance should be carried out by authorized Wallas service shop.
Protect the water system from freezing conditions. See detailed instructions below (winter storage).
Special recommendations Monthly use of the device will increase reliability by purging old fuel. Observe fuel provider recommendation with regard to the fuel type, fuel life lenght, additives and moisture removal. If the device has a separate tank: When selecting the fuel type, take note of the temperature limits of each particular fuel. Removal of the water from the tank Isopropanol based anti ice detergent meant for gasoline cars (no ethylene or methyl based) can be added to the fuel during the season. It is useful to make the addition after each couple of tanks and in the beginning and end of the heating season. The anti ice detergent binds the condensed water and prevents the sediment and contamination during the summer. For the dosage, observe the recommendations given by the manufacturer of the agent. Winter storage If the device uses the same tank as the engine: · Change the fuel filter. · Perform measures recommended by the boat/engine manufacturer to be performed before winter storage. If the device has a separate tank: · Drain the fuel tank in the autumn. · Clean the tank and change the fuel filter. · Fill the fuel tank with fresh and clean fuel in the spring. For the device itself, you do not need to do anything. The fresh water should be emptied during freezing conditions. The emptying process should be done by pushing compressed air to the fresh water pipes for winter. The coolant is not needed and not recommended to be changed for the winter. Follow the instructions of the coolant manufacturer’s change interval. Spare parts Spare parts list, www.wallas.com
An anti-freezing agent for diesel vehicles may increase the forming of scale at the bottom of the burner and therefore shorten the maintenance interval.
