MOUNTING-INSTALLATION INSTRUCTIONS
The chapter addresses both to the qualified persons which contribute to the boiler installation
and to the beneficiary which is concerned that the effected works to be done following the
safety rules in operation of all the installations which contribute to the good running of the
boiler.

!
The boiler installation is not the same with the boiler
starting.
The boiler starting must be done by the authorized
personnel in accordance with the current legislation.
There is no guarantee without the authorized personnel
signing the putting into service statement, and the
company withdraws any boiler guarantee or running
responsibilities.
The boiler location
The central heating
In accordance with the current regulations: The norms for the designing and execution of the
NG supply systems, The norms for the NG supply systems utilization and The norms for the
designing and execution of the liquefied petroleum gas supply systems (LPG).
There are several conditions for installing the boilers:
-The appliances have the protection IP 40 level.
-The boiler may be installed in any room with an air humidity of maximum 60% between
20-30º C.
The heating system will be designed by the qualified and authorized personnel, in the
mounting/installing activities.
It is important to pay attention to the pipes dimensions, head losses and heating elements
while designing the heating system.
The installation filling up must be done with softened water.
Couplings may be executed by gluing or compression fittings for the copper pipes, coupling
etc. The pipes must be provided with the necessary inclination for the ventilation and a light
evacuation to the adequate points from the installation.
Couplings and sockets
The evacuation. The evacuation points must be situated in the practicable places which allow
the water drainage from the heating circuit. It is recommendable that the minimum diameter should
be ½.
The ventilation. It is recommendable that the manual ventilators should be introduced on each
heating element (central heating). The water contains a certain quantity of resolved gases at the
first filling as well as the further water fillings of the heating system.
Once the system has been heated, the gases will be collected in the highest points of the
system whence they must discharged. The installation of some (manual or automatic) ventilators
will allow the evacuation both at the first filling and during the running, in these system points.
The filling. After the pipes connecting, the two circuits will be filled up with water gradually (the
boiler and the installation, respectively the coil from the DHW circuit) till the complete filling and it
should be checked so that there are no leakages.
