HYDRAULIC CONNECTION
The plumbing connections must be made in a rational way using the connections on the template of the appliance. To facilitate connection of the
pipes, all plumbing attachments have been fitted to the upper part of the appliance.
The appliance can be coupled with any other boiler already installed on the system. In this case, it is essential to fit all the necessary safety devices
and shut-off valves based on the system and intended use. It is also necessary to consider all laws and national, regional, provincial and municipal
regulations of the country where the appliance is installed.
The appliance can be installed with the expansion vessel closed because it is equipped with a device for stopping fuel loading, a safety manual reset
thermostat and a sound alarm, which are activated if the temperature becomes too high.
You can install the appliance in the same room as another boiler only if this has a sealed chamber; installation must be performed in
compliance with the current regulations.
When installing the appliance, it is advisable to fit an anti-
condensate mixer valve between the delivery and return pipes on the appliance’s
heating system. The anti-condensate valve must be calibrated to 55°C with a Kv value equal to or greater than 8 m
3
/h.
When connecting the appliance to the system, you should provide a zone that is always open (such as bathroom area) to enable the excess
heat dissipation of the water in the body of the boiler.
The maximum mains water pressure should never exceed 2.5 bar; recommended operating pressure is 1.5 bar (with the appliance in
operation).
An anti-limescale device must be installed if the water hardness exceeds 28°f. This device must be chosen on the basis of the specific
properties of the water.
TO AVOID COMPROMISING THE OPERATION AND LIFE OF THE HEAT PUMP, WE RECOMMEND INSTALLING A FILTER AND A MAGNETIC
DIRT SEPARATOR DOWNSTREAM OF THE RETURN PIPE ON THE APPLIANCE.
The appliance must be mounted exclusively by qualified personnel.
Scrupulously comply with the instructions given in this guide.
The manufacturer declines any liability for damages caused due to incorrect assembly.
