INSTRUCTIONS PRIOR TO INSTALLATION
The following notes and instructions are addressed to installers to allow them to carry out trouble-free installation. Instructions for
igniting and using the boiler are contained in the 'Instructions for Users' section. The installation must satisfy the requirements of
standards and local by-laws and technical regulations.
•
formation of ice in the siphon and in the condensation drain
• The boiler can be used with any kind of convector plate, radiator or thermoconvector. Design the system sections as usual,
though, bearing in mind the available capacity-head at the plate (see annex "SECTION" E at the end of this manual).
• Initial ignition of the boiler must be carried out by the Authorised Service Centre (as indicated on the attached sheet).
9. INSTALLING THE BOILER
in order to prevent the formation of air inside the primary circuit until
manual.
Connect the system to the gas and water inlets present on the lower bar of
the template. Make sure the rear part of the boiler (back) is as parallel as
possible to the wall (otherwise, shim the lower part). Fit two G1-1/2" taps
carry out important operations on the system without draining it completely.
On the Italian market, the system must comply with Raccolta R safety
provisions (limit thermostat, safety pressure switch, fuel cut-off valve, etc..).
Fit a hydraulic separator, sized according to maximum boiler and system
pressure, downline from the hydraulic connectors of the boiler. If you are
an external storage boiler.
9.1 BOILER PUMP
The boiler pump (15 - "SECTION" A) is modulating and circulates the water between the boiler and the hydraulic separator (for
hydraulic performance see the charts in annex "SECTION" E). The water in the system is circulated by the relative pumps (see
section 11.2.3).
