Where to install the appliance

 

 The appliance may be installed at ground level, on a terrace 

or on a roof, compatibly with its dimensions and weight.

 

 It must be installed outside buildings, in an area of natural air 

circulation, outside the dripping path of drainpipes or simi-

lar. It does not require protection from weathering.

 

 No obstruction or overhanging structure (e.g. protruding 

roofs, canopies, balconies, ledges, trees) shall interfere either 

with the air flowing from the top of the appliance or with the 

exhaust flue gas.

 

 The appliance's flue gas exhaust must not be immediately 

close to openings or air intakes of buildings, and must com-

ply with environmental regulations.

 

 Do not install near the exhaust of flues, chimneys or hot 

polluted air. In order to work correctly, the appliance needs 

clean air.

 

Defrosting water drainage

In winter, it is normal for frost to form on the finned 

coil and for the appliance to perform defrosting cy-

cles�

 

„

 To prevent overflowing and damage provide for a 

drainage system.

 

Acoustic issues

 

 Pre-emptively assess the appliance's sound effect in connec-

tion to the site, taking into account that building corners, en-

closed courtyards, restricted spaces may amplify the acous-

tic impact due to the reverberation phenomenon.

2.4 

 

 MINIMUM CLEARANCE DISTANCES

 

Distances from combustible or flammable materials

 

 Keep the appliance away from combustible or flammable 

materials or components, in compliance with applicable 

regulations.

 

Clearances around the appliance

The minimum clearance distances shown in Figure 2.2 

 p. 19 

(bar any stricter regulations) are required for safety, operation 

and maintenance.

2.5 

 

 MOUNTING  BASE

 

Mounting base constructive features

 

 Place the appliance on a levelled flat surface made of fire-

proof material and able to withstand its weight.

 

(1) - installation at ground level

 

 Failing a horizontal supporting base, make a flat and levelled 

concrete base, at least 100-150 mm larger than the appli-

ance dimensions per side.

 

(2) - installation on terrace or roof

 

 The structure of the building must support the total weight 

of the appliance and the supporting base.

 

 If necessary, provide a maintenance walkway around the ap-

pliance.

 

Anti vibration mountings

Although the appliance's vibrations are minimal, resonance 

phenomena might occur in roof or terrace installations.

 

 Use anti-vibration mountings.

 

 Also provide anti-vibration joints between the appliance 

and water and gas pipes.

 WARNINGS

General warnings

Read the warnings in Chapter III.1 

  p.  4, providing im-

portant information on regulations and on safety.

Compliance with installation standards

Installation must comply with applicable regulations 

in force, based on the installation Country and site, in 

matters of safety, design, implementation and mainte-

nance of:

 

„

 heating  systems;

 

„

 cooling  systems;

 

„

 gas  systems;

 

„

 flue gas exhaust;

 

„

 flue gas condensate discharge.

Installation must also comply with the manufacturer's 

provisions.
