5.1 - Opening the packaging
The appliance is supplied in cardboard packaging. Open
following the instructions given on the flaps of the packaging
itself.
5.2 - Dimensions and minimum
safety distances
It is necessary to leave free spaces around the boiler as
illustrated in figure 5.1 both for installation and maintenance.
5.3 - Choosing the place of installation
ATTENTION !!! The appliance must be installed
exclusively on a solid, vertical wall, which can support
the weight.
The appliance must be installed within the home, or
otherwise protected from atmospheric agents such as rain,
wind, sun, and especially freezing.
Define the room and suitable position for installation, taking
into account the following factors:
- connection of the fumes exhaust/air intake pipes;
- connection of the gas supply pipe;
- connection to the water supply;
- attachment of the central heating plant;
- attachment of the domestic hot water plant;
- electric connection;
- connection to the drain for the condensate produced by
the boiler;
- electric connection of the room thermostat;
- eventual connection of the safety valve drain;
- eventual attachment of the external temperature sensor;
5.4 - Supply and return
ATTENTION !!! This boiler has a safety valve
calibrated at 3 bar. A water head over 30 m must
therefore not be installed.
ATTENTION !!! COSMOGAS is not liable for any
damage caused by incorrect use of additives in the
central heating plant.
ATTENTION !!! The plant downstream from
the appliance must be made with materials that
resist temperatures up to 95°C and pressure of 3 bar.
Differently (e.g. plastic piping) the plant must be fitted
with the relevant protection and safety devices.
Before connecting the central heating pipes, wash the plant
thoroughly to eliminate any waste (hemp, radiators casting
sand, etc..), which could damage the appliance. This
washing operation must also be performed if the appliance
is replaced.
Figure 5.2 shows the positioning of the supply and return
fittings.

Install a metal mesh filter on the return pipe in order to stop
any plant residues before the return into the boiler.

Do not use the appliance for the introduction of any type
of additive into the plant.
