4.1.4 WATER QUALITY AND TREATMENTS
Paying attention to the following issues related to water
quality will greatly reduce the problems that may arise during
the life time of the boiler and ensure the continuity of the
working efficiency:
Piping and installation companents must be cleaned
before installation.
In old installations, iron oxide, sludge, sediment and
similar deposits should be cleaned.
The water in the system should be analyzed in terms of
hardness, pH, iron content and conductivity.
If all or a part of the heating installation is to be
operated by UNDERFLOOR HEATING SYSTEM,
PLATE HEAT EXCHANGER should be used and the
system should be separated from each other as
primary and secondary.
Faults that may arise if the water conditions are not
in accordance with the values specified in the table,
boiler will be considered out of warranty.
Wall Mount:
The dimensions of the hanger spaces behind the boiler are
shown below.
Drill the holes you marked with a 12 point drill.
Screw the hooks and hanger hooks into place.
Hang the boiler from the sling slots on the wall.

DYNAMIC AND CHEMICAL WASHING / FLUSHING:
In the newly established systems, to aviod the possible
substances in the installation (metal shavings, some oils,
residues of construction wastes etc.) flushing treatment is a
mandatory.
Likewise, it is a mandaory to apply the flushing treatment
without water given to the boiler in conversion of older
systems.
The methods of washing/ flushing are described in detail in
the manual GASSERO DYNAMIC AND CHEMICAL
WASHING / FLUSHING.
Neutral-based, non-acidic, non-alkaline registered products
can be used to clean the installation or keep the water
conditions at desired levels. You can get information from
GASSERO for cleaner, preservative or inhibitor type (stopper,
preventive) products or you can contact with SENTINEL or
FERNOX companies.
4.2 HYDRAULIC CONNECTIONS
According to the current legislation; total heating capacity of
the boiler or cascade system must be calculated to meet the
building's heat demand. All necessary components must be
installed and supplied correctly in the installation in a manner
to perform their duty. Protective and safety devices must be
used in the heating system as described in the current
legislation.
In order to separate the boiler from the installation, two
ball valves should be placed on the supply and the
return lines.
4.2.1 EXPANSION TANK
WALLCON X-treme boilers do not have an expansion tank.
So the capacity of the expansion tank should be selected
according to the capacity of the heating system and the static
pressure.
It is recommended to place the expansion tank on the
turn of the central heating system.
4.2.2 SAFETY VALVE
WALLCON X-treme boilers are equipped with a safety valve.
The hose of this safety valve must be connected to a drain.
Manufacturer cannot be held liable for damages caused by
water flow into the boiler or on the ground when excessive
pressure is generated in the heating installation.
Safety valve must not be used as a means of
draining water from the system.
Draining water of the safety valve can be very hot.
Beware of scalding.
12

4.2.3 CONDENSATION WATER DRAIN
Condansation water which is generated during to the
combustion, transfers to the water drain connection by the
syphon and drain hose.
Condensation water is acidic and corrosive (approx. 2 ph). So
all of the connections which are made for condensation water
must be made with PP type pipes. Condensation water must
be transferred to the drain with the shortest way possible. For
health and environmental reasons it mustn’t transfer such
places near people, animals and plants.
Condensation water must not be connected to rain drain
systems.
The condensate drain line must have a slope of at least
3%.
A neutralization tank should be used for condensate
water occurring in systems with a total power of 200 kW
and above.
It is mandatory to comply with the relevant local
regulations for the discharge of condensate water.

4.2.4 HYDRAULIC SEPERATOR
These are used to compensate the pressure differences in systems
where multiple pumps and / or heating circuits are used, to eliminate
excessive pressure differences between boiler’s inlet and outlet
water temperatures and to prevent thermal stresses in the boiler.
Dimensions, input and output distances should be selected
correctly.
Via a sensor to be placed on it, the general temperature of the
system is determined by the hydraulic seperator.
There must be an automatic air relief valve on the hydraulic
seperator.
In case the water in the system is dirty, chalky or
corrosive, plate heat exchanger should be used
instead of balance container.
4.2.5 PLATE HEAT EXCHANGER
Plate heat exchangers are hydraulic equipments that separates the
boiler and the installation (primary and secondary zones). Unlike the
hydraulic separator circulating water in the plate heat exchanger never
interfere with the water goes through the boiler and the water goes
through the installation. Only heat transfer occurs here.
Preferred for many purposes;
If the water in the system is very dirty, chalky or corrosive,
If the working pressure of the system exceeds the working
pressure of the boiler,
If a part or all of the system is required to operate with lower
temperature values. (eg. underfloor heating systems)
13

The plate heat exchanger must be used in the
following cases and the system must be separated
into primary and secondary.
-Heating systems which are consist of partly of fully
floor heating,
-Used, older systems,
-Systems that are dirty, corrosive, bacterial and
calcareous water.
Periodic inspection and maintenance of the plate
heat exchanger is highly important for the efficiency
of the system.
4.2.6 AUTOMATIC AIR RELIEF VALVE
ALUCON boilers have an automatic relief valve for the
evacuation of the air accumulated in the heat exchanger.
However, for the evacuation of the air that may occur in the
installation, it is necessary to place one or more automatic air
relief valves in the appropriate places of the installation. Local
regulations must be followed in this regard.
4.2.7 DEPOSIT AND DIRT SEPARATOR
To remove the dirt and particles form the water, a strainer or
deposit nd dirt seperator must be placed on the return line of
the boiler.
When the dirt, particles and similar deposits in the
system water are not cleaned;
The efficiency of the system decreases,
Installation equipments (pumps, valves, plate heat
exchanger, etc.) may be damaged due to overheating
A boiler damage may occur due to heat exchanger
clogging. Manufacturer cannot be held liable for
damages that may occur in such cases.
Strainers or deposit and dirt seperators on the
system should be checked frequently and cleaned if
necessary.
4.2.8 AIR INLET FILTER (OPTIONAL)
If WALLCON X-treme boilers will be used in to a dirty air
environment, they must be supported with the air inlet filters.
This optional filter must be checked regularly.
When the air inlet filter becomes dirty;
Emission values would be deteriorated and efficient
combustion wouldn’t be achieved.
The accumulation of soot occurs in the heat exchanger.
Loud ignition and combustion occurs.
Overheating, leakage and deformation would be
observed in the flue system.
Manufacturer cannot be held liable for damages
caused by dirty combustion air.
Don’t block the air filter partially or totally.
14

4.2.9 PUMP
Wallcon X-treme boilers are equipped with modulated
pumps according to the last ErP regulation.
4.3 FLUE CONNECTIONS
Flue and chimney connections must be carried out in accordance
with applicable regulations and relevant standards. Materials which
are used for the flue and chimney must be resistant to the
temperature, corrosive effect of condensation water and
mechanical stresses and must be gas-tight.
Never use the new boiler with the flues which are
used for solid/liquid fuel boilers or shunt chimneys.
Chimney system and the condensation drainage
systems connected to it should be checked once a
year and cleaned if necessary.
