You can also set up the appliance as an open one
(type B). If the appliance is set up as B22p, a special
air
fi
lter must be installed on the suction inlet of the
Udara air heater. This
fi
lter will stop the igniter ducts
between the premix burners from becoming
obstructed and will prevent individual objects from
falling into the appliance.
Always position measuring points in the FGO and
CAS so that a representative sample of the
fl
ue gases
and the combustion air can be taken. The measuring
points must, by preference, be positioned as close as
possible to the appliance.
The used CAS and FGO pipes must be gas-tight and
must meet the applicable standards. Multicalor has
PP and stainless steel pipes in its range that meet all
applicable standards. If the discharge of the
combustion gases and supply of combustion air takes
place through the roof, the especially designed and
approved icicle-low roof gland MUGRO SKYLINE
must be used.
Les conduites utilisées pour l’évacuation des gaz de
fumée et l’alimentation en air de combustion doivent
être étanches aux gaz et respecter les normes en
vigueur. Dans sa gamme, Multicalor possède des
conduites en PP et en inox qui respectent toutes les
normes en vigueur.
Connecting to another roof gland is not permitted in
relation to the approval in accordance with the Gas
Appliance Directive. If the discharge of
combustion gases and the supply of combustion air
takes place through the wall, the especially
designed and approved wall gland MUGRO WALL
must be used. Connecting to another wall gland is not
permitted in relation to the approval in accordance with
the Gas Appliance Directive.
The
fl
ue gas outlet must be installed with a minimum
slope of 5 cm/m towards the appliance so that the
condensate can
fl
ow towards the appliance.
4.2.1
Type B22p connection
The combustion air is taken from the room with regard
to a type B22p connection. The discharge takes place
through a gas-tight
fi
xed or
fl
exible pipe.

Intake fi lter (dusty rooms) or protective vent
There must always be a direct and non-closable air
supply outlet towards the outside with an area of 3
cm²/kW as the total set up power with a minimum of
150 cm². If local standards prescribe stricter require-
ments, you must, of course, comply with these.
Position a protective vent or, when setting up the
appliance in dusty rooms, an intake
fi
lter on the CAS
so that no individual objects can fall into the appliance
and the burner is safeguarded from contaminants.
Always position a measuring point in the FGO. The
maximum allowable length for the discharge pipe is
speci
fi
ed in table 4.2.7.
Danger!
Never connect an Udara appliance straight on to a
standard chimney! A gas-tight FGO must always be
used.
