exclusively on a solid, vertical wall, which can support
the weight.
The appliance must be installed in a suitable room taking
into account the following factors:
- connection of the exhaust/air intake pipes;
- connection of the gas supply pipe;
- connection to the cold water supply;
- connection of the domestic hot water supply;
- electrical connection;
- connection of the siphon and safety valve to a suitable
drain;
5.4 - Mounting the appliance
Refer to figure 5.3:
1.- place the paper template, provided with the appliance,
against the wall;
2.- check that the template is square;
3.- mark the holes for the plugs and hydraulic fittings on the
wall;
4.- remove the paper template;
5.- make the holes “A” and introduce the wall plugs “B”;
6.- hang the appliance on the plugs “C”
7.- make the appliance hydraulic and gas connections;
8.- make the hydraulic fittings.
5.5 - Domestic hot and cold water
ATTENTION !!! If water hardness exceeds 25°F
(250 mg/l) a polyphosphates water softener must
be installed on the incoming cold water supply (see
paragraph 5.10).
ATTENTION !!!
Install a filter with mesh no wider
than 0.5 mm² in the domestic cold water inlet.
ATTENTION !!! The domestic hot water
piping materials and fittings must be capable of
withstanding temperatures of a least 95°C and 10
bar pressure. These circuits must be protected with
suitable expansion together with both temperature and
pressure relief safety devices in accordance with all
relevant safety standards.
In figure 5.2 the service and maintenance valves are not
shown. Hydraulic and gas connections should be fitted with
isolation valves to accomadate service and maintenance
works.
