Hydraulic Installation
The hydraulic installation must be made by qualified personnel. The applicable installation
legislation is to be complied with, and the following recommendations should also be taken into
account:
- The inside of the installation piping should be thoroughly cleaned before switching on the
boiler.
- We recommend inserting cut-off valves between the installation piping and the boiler to
simplify maintenance tasks.

, as the Minny boiler is a condensing boiler
and a large amount of water may be generated. This connection should be made to an
appropriate drain or soakaway.
- Fill the siphon with water before starting up the unit, to prevent fumes coming out of it.
- If the system flow and return pipes follow a path where air pockets could form in certain places,
it is advisable to fit vent valves at these points. Also install drain cocks at the lowest point in the
system to allow for complete emptying.
