Instructions for the Installer
23
The appliance may only be installed in a permanently ventilated room as specified by the relevant
regulations. The air flow into the room where the appliance is installed must be sufficient for proper gas
combustion and room ventilation. The air intakes, protected by gratings, must be of suitable size (see
relevant regulations) and located so that they cannot be even partially obstructed. The kitchen must be
kept properly ventilated to disperse the heat and humidity produced by cooking processes: in particular,
a window should be opened or the speed of any fans increased after prolonged use.
4.4 Combustion gas discharge
Combustion gases must be discharged by means of hoods connected to a flue with reliable natural
draught, or a fan extraction system. An effective extraction system requires careful design by an
authorised specialist, and must comply with the regulation distances and positions. After installation, the
engineer must issue a certificate of compliance.
4.5 Gas connection
Connection with copper pipe:
The connection to the gas supply mains must be made so that no
stresses or strains of any kind are applied to the appliance. The
connection can be made using the adapter unit
D
with two conical
elements, always fitting the gasket
C
supplied.
Connection with steel hose:
use only continuous-wall stainless steel hoses compliant with the
relevant regulations, and always fit the gasket
C
supplied
between the fitting
A
and the hose
E
.
When connecting with a hose, ensure that the total length of the pipeline is not more than 2 metres; also
ensure that the hoses do not touch moving parts and are not crushed.
