3.2.2 Mandatory shut-o valve
▶ Provide a gas shut-o valve (manual) on the gas supply
line, next to the appliance, to isolate it when required.
▶ Provide a three-piece pipe union.
▶ Perform connection in compliance with applicable
regulations.
3.2.3 Gas pipes sizing
The gas pipes must not cause excessive pressure drops
and, consequently, insucient gas pressure for the
appliance.
3.2.4 Supply gas pressure
This appliance is equipped for a maximum gas
supply pressure of 50 mbar.
The appliance's gas supply pressure, both static and dy-
namic, must comply with Table 3.1 p.29 , with tolerance
± 15%.
Non compliant gas pressure (Table 3.1 p. 29 )
may damage the appliance and be hazardous.

The appliance gas supply pressure, both static and dynamic, must comply with the values in the Table, with a tolerance of ± 15%.
3.2.5 Vertical pipes and condensate
▶ Vertical gas pipes must be tted with siphon and dis-
charge of the condensate that may form inside the
pipe.
▶ If necessary, insulate the piping.
3.2.6 LPG pressure reducers
With LPG the following must be installed:
▶ A rst stage pressure reducer, close to the liquid gas
tank.
▶ A second stage pressure reducer, close to the appli-
ance.
3.3 COMBUSTION PRODUCTS EXHAUST
Compliance with standards
The appliance is approved for connection to a
combustion products exhaust duct for the types
shown in Table 1.2 p.23 .
3.3.1 Flue gas exhaust connection
▶ Ø 80 mm with gasket, on the rear, at the top (see di-
mensional diagrams, Paragraph 1.2 p.8 ).
