HYDRAULIC CONNECTIONS
The hydraulic connections depend on the type of
system.
However, there are a few "general rules":
•
The presence of a puffer (inertial storage tank) is
recommended but not mandatory. Its advantage is
that it releases the product from "sudden" requests
from the system and can be integrated with other
heat sources. It reduces fuel consumption and
increases the efficiency of the system.
•
The return temperature of water must be higher
than at least 50–55 °C to prevent condensate from
forming.
•
An accumulator (tank) is needed to heat low-
temperature radiant panels and must be installed
according to the panel manufacturer's instructions.
•
The material used in the circuit must be suitable to
withstand overheating.
•
Direct plumbing to radiators prevents proper
operation, owing to the small diameter of their pipes.
The return temperature of water must be higher than at least 50–55 °C to prevent condensate from
forming.
An anti-condensation system is essential and failure to install one will invalidate the warranty, on the basis
of incorrect installation.

Never light the fire in the product (even to
test it) when the circuit is dry (no water);
doing so may irreparably damage the
appliance.
