HYDRAULIC INSTALLATION
In this section you will find all the instructions necessary for the hydraulic installation.
Before realizing hydraulic system and gas supply for the appliance, the professionally qualified personnel is advised to read
Paragraph 3.1
→
7, providing important recommendations about safety and references to current regulations.
5�1
GENERAL INSTALLATION PRINCIPLES
Prior to installation, carry out careful internal cleaning of all pipes and every other component to be used both on the hy-
draulic plant and the fuel supply plant, in order to remove any residues that may compromise operation of the appliance.
Installation of the appliance must be carried out in compliance with current regulations regarding design, installation and mainte-
nance of heating and cooling plants and must be undertaken by professionally qualified personnel in accordance with the manu-
facturer’s instructions.
During the installation stage, observe the following indications:
▶
Check that there is an adequate mains gas supply, in accordance with the manufacturer’s specifications; for the correct supply
pressure, refer to Paragraph 5.4
→
23.
▶
The appliance may be installed both indoors and outdoors; in case of outdoors installation, the appliance must be located in an
area in which air circulates naturally and which does not require any particular protection from the weather.
▶
No obstruction or overhanging structure (protruding roofs, eaves, balconies, ledges, trees) may obstruct the exhaust fumes out-
let at the top of the appliance.
▶
Do not install the appliance, in configuration B, in the immediate vicinity of flue outlets, chimneys or other such features, so as to
prevent warm or polluted air from being drawn in by the combustion fan. In order to function correctly the appliance must use
clean air from the environment.
▶
If the appliance is installed near buildings, make sure it is not on the dripping line from gutters or similar.
▶
A cut-off valve and vibration damping coupling must be fitted on the gas supply.

POSITION OF THE APPLIANCE
Lifting the appliance and placing it in position
Do not remove packaging during handling on the installation site.
Packing must only be removed upon final installation.
When unpacking the appliance, do not remove the protective cap on the top panel as this can allow dirt and water to enter
the interior of the appliance.
The appliance can be installed at ground level, or on a terrace or roof (if they are able to sustain its "dimensions" and "weight"). The
appliance must be installed in an area which is always accessible�
The dimensions and weight of the appliance are given in Paragraph 3.4
→
9.
Supporting base
Always place the appliance on a levelled flat surface made of fireproof material and able to support the weight of the appliance.
▶
Installation at ground level
If a horizontal base is not available (see also "Supports and levelling"), it is necessary to create a flat level base in concrete at least
100-150 mm larger than the dimensions of the base of the appliance on each side.
For the dimensions refer to the tables in Paragraph 3.4
→
9.
▶
Installation on a terrace or roof
Position the appliance on a levelled flat surface made of fireproof material (see also "Supports and levelling").
The structure of the building must be able to sustain the weight of the appliance added to that of the supporting base.
For the weight refer to the tables in Paragraph 3.4
→
9.
In addition, it is advisable to use flexible connections (anti-vibration joints) between the appliance and the hydraulic and gas supply
pipes.
Avoid placing the appliance on the roof directly above locals requiring quietness.
Supports and levelling
The appliance must be correctly levelled by placing a spirit level on the upper part.
If necessary, level the appliance with metal shimming; do not use wooden spacers as these deteriorate quickly.
CLEARANCES AND WARNINGS
Position the appliance so as to maintain minimum clearances from combustible surfaces, walls or other appliances, as illustrated
in Figure 5.1
