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.
