For further information on the installation of the
ue gas exhaust/air intake duct, please refer to the
installation guide for the ue gas exhaust/air intake
ducts D-GPP001, available on the Robur website.
3.4.2.1 Installation with separate ducts
If the appliance is installed with separate pipes, suitable
pipes and components, available as optional, must be
used.
At the design stage, it must be veried that the sum of the
pressure drop of all components used does not exceed
the value of the available residual head (Table 3.2 p.13 ).

Description Code 3001 3002
residual head Pa 25 25
Air pipe internal Ø 33 mm OPRL000 Pa/m 0,6 0,6
Horizontal ue gas pipe internal Ø 33 mm OPRL000 Pa/m 1,5 1,5

Condensate discharge Ø 35 mm OSCR003 Pa 0,0 0,0
If the ue gas pipe is longer than 1,5 metres, a condensate drain (available as OSCR003 optional) must be installed
