6.2. Hot water connection
Overview Operation Maintenance Warranty
If the installation is made with synthetic pipes (e.g. : PER, multi-layer…), install mandatory a
thermostatic control valve at the connection pipes of the water heater. The setting should be done in
relation with the specification of the installed piping.
Do not connect copper tubes directly on the tank connection. You have to fit the supplied insulation
union (included in the supply).
In case that the tank connection is corroded without this protection the warranty will not apply.
The use of a siphon to connect to sew water is mandatory (the siphon must not be made with the
supplied tube)
.
6.3. Condensate evacuation
Depending on the degree of humidity in the air you can get
up to 0,25l/h of condensation . The evacuation of
condensate should not been made directly to sew water
because of possible corrosive gasses damaging the exchanger
fins and water heater parts.
The temperature drop of the air passing through the exchanger forms condensation from humidity
in the air. The condensed water is evacuated on the rear of the tank using the supplied plastic tube.
7. Air connection
If the volume of the installation room is not sufficient the water heater can be connected to ducts with a
diameter 125 mm. If the ducts are not insulated this could generate condensation in the ducts during
operation.
The use of insulated ducts is mandatory.
It is mandatory to remove both grids
in case of a ducted installation.
EXIT
ENTRY
If the water heater is ducted the parameter setting has to be adapted.
The total pressure drop of ducts and accessories for air intake and exit has to be less than 70 Pa. The
recommended length of ducts has to be respected.
