Fuelling air
CRISTAL fuelling air can only be mounted in rooms where there is sufficient air power supply
for fuelling. To have the chimney function correctly, it is essential that the fuelling air reaches
the hearth through a fine pipe on the appropriate inlets, provided at the sides and rear of
the chimney. A 12.5 cm fitting (A) is supplied, which is to be applied to the inlet to be used
(fig. 6).
The connection with the outside must have a useful passage section of at least 125 cm
along its whole path. The mouths not used for connecting the fuelling air passage flexible
pipe, must remain closed with a lid.
Whenever the air volume results scarce and the type of building in which the chimney is
installed particularly air sealed, it will be necessary to install a supplementary air inlet of 120
fig. 6
cm (ø 12.5 cm).

Butterfly valve
fig. 7
The fuelling air must flow to the hearth regulated by a butterfly valve.
The butterfly valve is delivered as an accessory together with a flexible pipe and the fixing
bands.
Unless the butterfly valve is mounted in a fixed and solid manner, the compact chimney
cannot be started.
Mount the fuelling air regulating lever in the most adequate position under the threshold.

The air for heating
the room air enters from the side inlets (n 13 - fig.1of page 22) obtained at the bottom of
the shell, heats up, climbs up along the air space and exits hot from the mouths on the lid
of the same shell.
In this set-up, the air inlets lids on the shell must be removed (n 13- fig.1 of page 22) and
equal passages must be provided on the coverings so that the air to be heated has easy
access to said inlets.
