If the volume of the installaBon room is not sufficient the water heater can be connected to ducts with a
diameter 160 mm. If the ducts are not insulated this could generate condensaBon in the ducts during
operaBon. The use of insulated ducts is mandatory.
If the water heater is ducted the parameter sejng has to be adapted.
The total pressure drop of ducts and accessories for air intake and exit has to be less than 150 Pa.
The recommended length of ducts has to be respected.
