1.2. RECOMMENDATIONS ON USING THE
BOILER ECONOMICALLY
Your boiler is adjusted for economic usage in the factory,
we recommend not to change it.
Correct Capacty Selecton
Boiler capacity must be selected accordingly by properly
calculating the heat loss of the place where the boiler will be
used. Appliance without the adequate capacity will response
late to the heating demands, appliances with over capacity may
cause discomfort and more fuel consumption as it will activate
more frequently. Thus, it is necessary to select boiler capacities
according to the place of use.
Isolaton
Isolation condition of your building is the most important issue
preventing the heat loss and decreasing the gas consumption.
Furthermore, as it has the thickest isolation of its class, heat loss
is minimized.
Radators
Make sure to balance pressure distribution of your heating
system in the house by arranging the reduction settings of your
radiator valves. Putting furniture in front of radiators cause
discomfort and more fuel consumption as it prevents the air
circulation. Turning down the radiator valves of rooms which
haven’t been used for a long time or reducing to the lowest if
thermostatic radiator valve is being used and closing the room
doors provide savings.
Domestc Hot Water
If you are using the boiler with a DHW boiler, we recommend
you to adjust temperature of domestic hot water as (38~42 °C).
Setting the temperature adjustor to a low level provides savings
at a large rate.
Thermostatc Radator Valves
You can acquire both saving and comfort by balancing the
heat distribution in the places of home via using Thermostatic
Radiator Valves.
Room Thermostats
As you will have the opportunity to adjust ambient temperature
with room thermostats according to comfort and economy
timers, your boiler will operate more economically. Thus, both
you can adjust your room temperature as you wish and you can
save on energy to about %6 with each degree of temperature
decrease.
Ventlaton
Don’t leave windows half open to ventilate the room/rooms.
In that case, although there will be no significant improvement
in the room air, there will be constant heat loss. Opening the
windows fully for a short period of time results better. While
ventilating the rooms, reduce the thermostatic radiator valves to
the lowest.

2.2. HEATING AND DOMESTIC HOT
WATER SYSTEMS
Radiator and underfloor heating installation should be
constructed in accordance with legislation in force technical
specifications and heat loss calculation.
• Heating system must be installed to resist pressure up to at
least 6 bar.
• Pressure reducer must be installed if the mains pressure is
above 6,5 bar.
• It is recommended to install heating system as (at least)
double or mobile line by avoiding bends and additions as
much as possible.
• A strainer filter must be installed in heating return line and, if
DHW boiler (mains) is being used, in inlet line.
• Additional expansion tank with at least 50 liters must be
used according to the heating water volume capacity and
operating temperature of the heating system (closed circuit).
• If the valves of room thermostat and thermostatic radiator
are going to be used together; thermostat valves shouldn’t
be installed to radiators in the places where there’s room
thermostat!
• Cross connection must be made for efficient operation in
radiators longer than 1,5 m.
• Covers shouldn’t be used in the transitions of heating and
domestic hot water from walls, and wall clamps must be
immobilized not to slope in expansions due to heating.
• An external DHW boiler must be connected to the boiler for
Domestic Hot Water supply. It is necessary to use three way
valve and DHW boiler sensor in the product accessory group
in case of usage with DHW boiler.
• Heating system must be washed and cleaned up before
filling!
2.3. FILLING THE FLUSHER FOR
CONDENSATION LINE
The condensation siphon must be filled with water after
completing wall-hanging of the condensation boiler, electrical
connections, heating lines, hot domestic water connections and
condensate drainage line (Figure 2.2).
Condensation line outlet connection must be sealed.
However, against the risk of waste gas leak in the first
operation, pout about 1 litre of water into the chimney
before chimney-mounting of siphon in the boiler. Thus, the water
in the siphon will prevent the leakage of waste gas.
The tilt of the condensation water hose and line must always be
downward.
2.4. CONNECTION OF WASTE GAS
CHIMNEY PIPE SET AND ACCESSORIES
Chimney accessory of hermetic boilers sets to be used
in the waste gas installation should be original
Warmhaus chimney sets and they should be used taking
into account sizes and restrictions given in the mounting
instructions.
If different waste gas pipes and/or accessories are used
other than original Warmhaus waste gas chimney pipes
and accessories, the boiler will not be started by the
Authorized Service and therefore cannot be guaranteed!
The boiler should only be mounted with plastic material and the
original Warmhaus air intake and waste degazing device.
Plastic ducts cannot be installed outsides, at intervals over
40 cm, without proper protection against UV and weather
conditions. Each pipe is identified by a promoting and distinctive
Warmhaus sign in the notes.
If more than one Viwa 90-150 boilers are connected in
parallel to the same hydraulic installation and operated
as cascade, it is necessary to use the product code for
each boiler is: O100 / 100 Waste Gas Chimney Block with
153.11.660.600040 product code or (O100-O100) Chimney Block
products with 153.11.660.600068 product code must be used for
each boiler. In the same installation, the blocks should not be
used together and the same block product should be used for
each boiler.
If the Vwa 90, Vwa 115, Vwa 125 and Vwa 150 bolers are
used as cascade systems and our blockng products are
not used n each boler, bolers wll not be started by our
authorzed servce!
IMPORTANT
The following must be checked during starting the
boiler:
- Make sure that there is no liquid or combustible
materials near the boiler.
- Ensure that the electrical connections are made correctly and
that the ground wire is connected to a good grounding system.
- Open the gas valve and check the durability of connections
including the burner, burner exchangers and heat exchangers.
- Ensure that the boiler is adjusted for operating for the supplied
gas type.
- Check that the chimney pipe in outlet of combustion products
is not blocked and is properly mounted.
- Make sure that any (safety) shut-off valve is open.
- Ensure that the system is filled with water and thoroughly
ventilated.
- Check that the circulation pump is not jammed.
- Discharge the air that may be in the gas line, discharge the air
in the gas pipe by operating the pressure discharge valve at the
gas pipe inlet.

• Concentric extension pipes and plug-in
type seal for elbows. To connect the
possible extension connections of the
waste gas chimneys to other elements
of chimneys: connect the male (straight)
side of concentric pipe or concentric
elbow to the female side (sealed side) of
the previous part, in this case make sure
you have fitted the required washer, so
the connection will be tight and integrity
of parts of the set will be ensured.
Please note that in the case
where shortening of the
discharge chimney and/or
extension is required, the inner chimney
must always be 5 mm ahead of the outer
pipe..
For safety reasons, the
absorption/ discharge chimney
of the boiler should not be
blocked, even if for short-time or
temporarily.
During installation of the
horizontal pipes, the pipe tilt
must be kept upwardly a
minimum of 3%, dowelled in every 3m
and a retaining clamp must be used.

2.4.1 (Ø100/150 MM) INSTALLATION WITH
HORIZONTAL CONCENTRIC FLUE SETS CONNECTING
THE HORIZONTAL CONCENTRIC FLUE SET TO THE
BOILER
Since your boiler is hermetic model, if it is used with concentric
chimney sets, it takes the air that it uses from the outside and
emits waste gases due to combustion to the outside from the
same chimney group. The use and installation of the chimney
is very important to avoid emission of waste gases which are
extremely harmful, so cautions should be taken into account
when connecting chimney.
•Select the chimney necessary for the chimney connection
from the mounted place of your boiler and outside. If the
horizontal/vertical chimney set is insufficient, select the most
appropriate elements from our list of connection accessories,
taking into account the warnings mentioned in our operating
manual.
•Fix the flange under Elbow part (1) in Figure 2.14 on holes on
the boiler by using the Flange Seal (10) and screwing with the
flange connection screws (11).
•Two sealing gaskets (2) from the concentric chimney set are
placed in the inner pipe slots at both ends of the 90° elbow.
•To group the chimney outlet terminal, intertwine the outer
wall (EPDM) gasket with chimney terminal as seen in Figure
2.6. After intertwining the chimney outlet terminal from the
outer side of wall and previously opened holes insert the
Internal Wall Connection Gasket (7) in chimney terminal.
Insert the other end of EPDM connection gasket you have
already inserted in 90° chimney elbow, into the chimney
outlet terminal Be careful that gaskets are placed properly.
2.4.2 MOUNTING WITH VERTICAL CONCENTRIC
CHIMNEY SETS
The boiler also has the possibility to connect vertically to the flat
and sloped roof by means of the accessories it has according to
the situation of the environment you will mount on. In straight
connections, (Ø100 / 150 mm) vertical chimney set should not
exceed 11m.

2.6. MOUNTING TO PARTIALLY -
PROTECTED OUTER SPACES
Installaton nstructons: This boiler can be installed in partially
protected outer spaces. Partially-protected place means that
the boiler is located at places where it is not directly exposed to
atmospheric factors and precipitation (rain, snow, hail, etc.).
Protecton Aganst Freeze: The boiler is equipped with a system
that automatically prevents the freezing by putting the pump
and the burner into operation when the water in the boiler
falls below 5 °C. The protection against freeze depends on the
following conditions:
- If the boiler is correctly connected to gas and electricity
sources;
- If the boiler is supplied constantly from gas and electricity
sources (if main switchgear is on)
- If the boiler does not come to the fault condition due to lack of
ignition;
- In order to ensure the circulation of the installation water, the
installation valves and radiator valves under the boiler must be in
the open position. Under these conditions the boiler is protected
against freeze up to an ambient temperature of -5 ° C.
The lowest temperature -5°C. If the temperature of the boiler is
mounted in an environment that may be below -5 °C and if the
gas inlet is cut off or the ignition fails, the Anti-Freeze System
will not be put into practice and freezing/icing will occur in the
device. The following instructions must be followed to prevent
freeze risk:
- Protection against freeze by placing in the heating circuit an
antifreeze in a percentage of the required minimum temperature
for the heater by a well-known antifreeze producer (special
for heating appliances) in which the heater is intended to be
stored, and by carefully following the instructions. The materials
from which the boilers are made are resistant to ethylene glycol
and propylene-based icing inhibitor liquids. Observe suppliers'
warnings about their life and possible disposal methods.
Protectng the boler aganst freeze/cng s only guaranteed
on these condtons:
Damage caused by failure to comply with the foregoing
and interruption of electrical energy shall be excluded in the
effectiveness of the guarantee.
If the boiler is mounted in places where the temperature falls
below 0 °C (both for domestic use and for heating purposes),
both the heating installation and the domestic water pipes must
be insulated.
2.7. ELECTRIC CONNECTIONS
The electric safety of the boiler takes place only if it is fully
connected to an effective grounding system, as stipulated by
the current safety regulations. If there is no grounding, the
grounding shall not be made on the socket through neutral line!
The use of gas and water connection pipes for grounding is
dangerous and unacceptable.
WARMHAUS A.S. cannot be held responsible for any damage or
loss that may occur to a person or property due to the absence of
grounding connection of the boiler and the failure of grounding by an
authorized electrician to comply with the applicable regulations and
standards..
Also check that the electrical installation meets the maximum
power that can be pulled specified in the technical specifications
label on the boiler. Boilers should be connected with "X" type
special power supply cables without socket. The Warmhaus boilers
have a protection level of IPX5D. Power supply cable must be
connected to a 230 V + 10%; - 15% 50Hz network with L-N polarity
and grounding connection; on the same network, a high voltage
category 3rd class multi-pole contact cutter should be installed.
When it is necessary to change the cable, be sure to contact our
Authorized Warmhaus Service.
The power supply cable must follow the specified route.
If the fuses on the adjustment card are to be replaced,
use a 2A or 3.15A quick-type fuse. The use of adapters,
multiple sockets and extension cables is not permitted for the
device to be supplied from the general electric network.
2.8. OPTIONAL CONTROLS: ROOM
THERMOSTAT, EXTERIOR TEMPERATURE
SENSOR AND OTHER
Control devices such as Room Thermostat, Outside Temperature
Sensor, etc. must always be connected to Warmhaus boilers by
an authorized service personnel. If the connections are made by
unauthorized persons, the boiler will be out of warranty.
Control devices such as Room Thermostat, Outside
Temperature Sensor, etc. are provided to Warmhaus
boilers as optional accessories and must be Warmhaus
certified.
See use instructions for placing the Outside Temperature Sensor.
This sensor, which can be connected directly to the electrical
installation of the boiler, automatically reduces the maximum
stream water temperature at the installation when the
outside temperature increases to run the temperature sent
to the heating installation in compliance with the exterior
temperature changes. The Outside Temperature Sensor is
actuated when connected independently of the typology
of the room thermostat used and works in conjunction with
room thermostats. The relationship between the installation
inlet temperature and the outside temperature is determined
according to curves in the diagram from the position of the
button on the boiler panel (or on the control panel if connected
to the boiler) (Figure 2.15).
The electrical connection of the Outside Temperature Sensor
should be made on pins no. 3-4 in the Low Voltage range where
terminal pins 1-14 are located in the boiler electronic board
(Figure 2.18).

HEATING WITH OTC ENABLING (OUTSIDE
TEMPERATURE CONTROL = OTC)
Working mode heating with OTC gets enabled by operative
winter setting and connected outside probe.
WORKING
By connecting to Viwa boiler and external temperature probe
there is the change of the parameters counting heating setpoint
for each zone. sensor spesification must be 10 kOHM - βvalue
3535. This Beta value can be changed on Par 07 = 0 as default
3435 or can be changed via Par07 = 1 means sensor Beta value
= 3977 )
OTC REMOTE CONTROL PRESENCE
The board passes to the remote control the external
temperature value read by the probe; the remote control uses
this information to find the heating setpoint for the intended
zone.
OTC REMOTE CONTROL ABSENCE
In this case the outside temperature value is used to change
(compensate) the heating setpoint which had been set by
the user interface for the intended zone. The heating Set
can be found by the climatic curves considering the outside
temperature and keeping them inside the ranges values:
- Par 20 and Par 21 INST for zone 1
- Par 23 and Par 24 INST for zone 2
- Par 26 and Par 27 INST for zone 3
The curve can be selected from a value between 3 and 40 (a
step of 1) with installing parameters Par 22 INST for the curve 1,
Par 25 INST for the curve 2 and Par 28 INST for the curve 3.
The user pushing the keys can set, for each circuit, a shift of
the of room set and a variation of the climatic curve (±5°C with
pass of 1°C and default for both 0°C). If Par14 INST ≠0 The
SetPoint is counted accordingly to the set climatic curve and
the value, which is read on the input 0…10VDC, corresponds
to the set room shift (0 V = -5, … , 10 V = +5). In this case is no
more possible to set the shift by the keyboard. The set room
shift received by the command 0…10VDC could be seen pushing
INFO menu. The mode enabling and the working corresponds to

(NaClO), potassium hypochlorite lime (Ca(CIO)2). Strong
oxidizers are often added as biocides to the water to reduce
microbiological activity of the water.
• Strong complex actuators should be avoided. The
most likely to occur are: chlorides (CI-), ammonia and
ammonia containing chemicals (NH3, amines, EDTA, etc.),
polyphosphates (such as Calgon). Strong complex actuators
are also known as “chelates” (EDTA, NTA), are commonly
used to control scaling by typically forming fixed heat-soluble
complexes with calcium and magnesium.
• The installation should be designed so that all air can be
discharged, ensure that all air is discharged after installation.
Preferably, you can also install air separators.
• The total volume VT of water filled, refilled and completely
filled throughout the lifetime of boiler at a total hardness of
11°d or 11°dH (~2mmol/litre) shall not exceed the following
values: 15 litres/kW x [kW] for Viwa 90-150 series, Taking into
consideration that the water in the installation is likely to be
completely filled up several times over the lifetime of the heat
exchanger, the maximum values in the application must not
exceed the following values: 7.5 litre/kW x [kW] for Viwa 90-
150 series.
EXAMPLE 1:
Viwa 90 boiler 90 kW, the total volume of the installation is 1100
litres. The maximum permissible hardness for Viwa 90 can be
obtained from 7.5 litres/kW at 11°d.
This is 7.5 x 90 x 11 = 7425 litres. °d
The maximum permissible hardness at 1100 litres, the total
volume, is 7425/1100 = 6.8°d.
This means that the water in the installation must be softened to
a value of 6.8°d or less.
EXAMPLE 2:
Viwa 150 boiler 150 kW, the total volume of the installation is
5,000 litres. The maximum permissible hardness for the Viwa
150 can be obtained from 7,5 litres/kW at 11°d.
This is 7.5 x 150 x 11 = 12,375 litres.

Parameters such as PH, hardness, conductivity, oxygen, flux
residues, oil residues and corrosion products due to installation
can have negative effects on the heat exchanger.
Before filling (old and new) the installation, it should be
thoroughly rinsed in accordance with EN 14336 with clean
running water from the faucet.
For water treatment Warmhaus only permits the products listed
below.
For the protection and long-term use of the heat exchanger,
Warmhaus always specifies the following criteria for the quality
of the installation water and the filling water:
• PH should be kept between 6.5 and 8.5.
• The maximum permissible chlorine content for the aluminium
heat exchanger is 250 mg/liter. The maximum permissible
sulphate and nitrate content to limit the microbiologically
affected corrosion (MIC) risk is 100 mg/litre.
• Strong oxidizing chemicals should be avoided. Some
examples of oxidizers include, but are not limited to:
chlorine (C12), hydrogen peroxide (H2O2), bromine (Br2),
ozone (O3), chlorine dioxide (CIO2), sodium hypochlorite

2.10. USING OUTDOOR TEMPERATURE
SENSOR (OPTIONAL)
Outside Temperature Sensor (optional) is adjusted by
Authorized Service according to average outside temperature of
your province with P04 parameter.
Thus, it provides efficient and economical operation according
to the need by relieving of constantly adjusting the heating
temperature in changing weather temperatures, through
reducing the temperature of heating water when outside
temperature increases and increasing the temperature of
heating water when outside temperature decreases. This
sensor activates when connected independently of the
presence or type of the used thermostat. Relation between
returning temperature of the system and outside temperature is
determined according to the position of the button on the Boiler
panel as the curves in the following diagram.

litres is 12,375 / 5000 = 2,48 °d.
This means that the water in the installation must be softened
to a value of 2.48 °d or less. The following table shows the other
examples of maximum water hardness in °d.
In all cases, the maximum hardness of the water in the
installation must be less than 25°d.
2.12. WATER TREATMENT
• In the case of water softening by ion exchange, the mixed ion
exchange is preferred. Additional pH buffering should then be
provided.
• Avoid cation exchange with K+ or Na+. If cation exchange
with K+ or Na+ is used, pH control is required to limit the pH
variation over time.
• In the case of water softening by anion exchange, only
methods using sulphur (SO42-) as negative ion are allowed.
Ion exchange methods using Cl- or CO32- negative ions are
not allowed. If demineralization is used, a chemical additive
will be added for pH control.
• Never fill the system with distilled water, as this will seriously
corrode the aluminium heat exchanger.
• In order to limit the risk of corrosion, the water conductivity
should preferably be less than 100 μS/cm.
• The conductivity of untreated installation water should not
exceed 600 μS/cm.
• If the installation water is treated with one of the products
described below and according to the manufacturer's
instructions, the conductivity must not exceed 1500 μS/cm.
• If the conductivity is higher than the specified values, empty
the system and clean and fill with clean tap water according
to EN 14336, preferably with recommended cleaning
products.
• There are many products in the market claiming to clean and
protect the heating systems. Unfortunately, there are a few
products that have actually proved this in practice. For this
reason, Warmhaus only allows the following quality products
for water treatment;
Manufacturer: Fernox (www.fernox.com)
- Cleaner F3 : Removes corrosion, lime and sludge
- Protector F1 : Protects against corrosion, lime and sludge
- Alphi-11 : Prevents freezing and provides protection
against corrosion and lime
Manufacturer: Sentnel (www.sentnelprotects.com)
- X 100 : General inhibitor protection
- X 200 : Noise reduct
- X 300 : System cleaner for new installations
- X 400 : System renewing sludge cleaning for old
installations
- X 500 : Protective antifreeze and general protection
Manufacturer: Clarant (www.antfrogen.clarant.com)
Antifrogen-L : antifreeze (mono ethylene glycol)
(Note: Antifrogen-N is toxic, Antifrogen-L is
recommended)
Note that all these products must be used strictly in accordance
with the instructions of the water treatment manufacturers.
WE ALSO STRONGLY RECOMMEND THE
FOLLOWING:
• Use a register to fill, refill, completely fill water, water quality
measurements and water treatment.
• Use only non-diffusing material, especially for underfloor
heating.
• Always install air discharge devices at the highest point in the
installation.
• In order to avoid as much as possible of filling, refilling and
completely filling, place ball valves near the boiler on the
installation and in strategic locations (anticipating future
expansion of the system).
• Install a water meter to check the amount of filled, refilled, and
completely refilled water.
• Install a filter in return.
• In case of any doubt, install a plate heat exchanger to
hydraulically separate the boiler from the installation.
• Prevent leaks; If there is a leak, repair it as soon as possible.
We recommend that you add this description of the
preventive water treatment to your installation and operating
manual.
The above-mentioned water quality requirements apply to
aluminium heat exchangers.
The requirements of other parts in the installation are not taken
into account.
