3 INSTALLATION
3.1 Standards
The use of gas control boxes is subject to strict regulations. It is therefore
important that the UNI 7129 and 7131 standards are observed.
For liquefied petroleum gas (LPG), the installation must comply with the
requirements of the distributing companies and with the requirements of
the standards cited above.
The appliance is sold without the inlet and outlet device as a different
device is required according to the specific installation; please consult
the accessories catalogue to request any of the various different devices.
3.2 Positioning
- The appliance should be installed on a suitable wall and it is essential
that the minimum distances be left around it to allow for maintenance
work to be carried out (see section "Wall mounting").
- The appliance should not be positioned above a stove or other cooking
appliance so as to avoid kitchen vapour grease being deposited on it
and affecting operation.
- Heat-sensitive walls such as those made from wood should be protect-
ed with suitable insulation.
3.3 Wall mounting
3.3.1 Models for indoor installation
The appliance must be installed on a suitable wall:
- the appliance should never be closed in a unit or niche; there should be
a gap of at least 20 mm between the side walls and the appliance, so
maintenance work can be carried out
See Fig. 20
- once the position of the appliance has been established, position the
template supplied and mark the position of the holes, then remove it
and drill 2 Ø 8 holes
See Fig. 21

- reposition the template and fix it with the plugs supplied
- the most common type of rear and horizontal outlet is described below;
Guide the wall template fins into the slots on the paper template
- mark the centre of the pipe hole;
- drill a hole Ø 110 mm as indicated on the paper template
See Fig. 22 and Fig. 23
- cut the pipes to the correct length according to the thickness of the wall.
If done correctly, the 60 mm Ø flue pipe should protrude by 7.5 mm with
respect to the 100 mm Ø air duct
- insert the specific pipe made up of two concentric pipes in the hole in
the wall
See Fig. 26
- seal the gap between the 100 Ø pipe and the hole in the wall with ce-
ment-based mortar, positioning a piece of paper so that the tube does
not remain fixed to the wall itself, so as to facilitate subsequent disas-
sembly. Place the appliance in the chosen position, with reference to
the measurements indicated in this instruction booklet in the “Func-
tional elements of the appliance / Max. dimensions and connections”
section.
3.3.2 Models for outdoor installation
The appliance has been designed only for installation outdoors in an area
that is partly covered. For this reason it must be installed in the open,
outdoors with natural aeration and ventilation, without stagnant zones for
combustion products, which should be rapidly dispersed by means of nat-
ural convection or by the wind.
The discharge outlet of the appliance should be free of obstructions, ob-
jects or bodies that could prevent it from expelling the flue gases correctly
and protected from an contacts during or after operation: it is possible it
overheats and cause burns.

When the appliance is being installed the minimum distances of the dis-
charge/suction line must comply with current local legislation, having re-
gard for any other appliances installed, openings, architectonic elements,
and boundaries.

(*)
For type A appliances the minimum distance coincides with the cen-
tre of the outlet section for combustion products going into the air.
(**)
When positioning the appliance distances of not less than 500
mm must be adopted from materials sensitive to the action of the
combustion products (for example, plastic eaves and drainpipes,
protruding wood elements, etc.); for smaller distances use suitable
screening with regard to said materials.
