INSTALLATION IN AN EXISTING FIRE-
PLACE FITTED
WITH
EXTERNAL AIR
INTAKE
(when part numbers are not speci
fi
ed, refer to the
speci
fi
cation tables on the previous pages)
N.B.:
if you
do not
want to alter the existing
hood, the installation must be carried out
without hot-air ducting (leaving the upper
outlets closed).
In this case, the hot air only enters the room
through the slots on the front, above the door.
a)
make a pit (Fig. A), in the basement of the
existing
fi
replace, big enough to hold the ex-
ternal air intake mechanism (Fig. B)
b)
this pit must communicate with an ex-
ternal air inlet duct through a passage with
cross-sectional area of at least 80-200 cm²
(depending on the model)
c)
position the mechanism (Fig. B)
fl
ush with
the upper face of the
fl
oor, carefully sealing
the points where outside air may leak
d)
make sure the damper moves correctly
(Fig. B)
e)
with a hose clamp Ø 16-20 cm
fi
t a length
of at least 2 meters of stainless steel
fl
ue, with
the
fi
tting for a Ø 16 cm
fl
ue or the
fi
tting for a
Ø 20 cm
fl
ue (Fig. C)
f)
wrap the section of steel pipe with a multi-
layered ceramic
fi
bre mat or equivalent mate-
rial (Fig. C)
g)
slip the section into the
fl
ue of the existing
fi
replace and make sure the thickness of the
ceramic
fi
bre wrapping is suf
fi
cient to com-
pletely
fi
ll the space between the new steel
pipe and the existing
fl
ue (Fig. C)
h)
place Firebox
®
onto the mechanism (Fig.
B) checking that:
- the lower
fl
ange has been removed to allow
the
fl
ow of external air;
- The de
fl
ector is open, using the knob
located at the top left on the front of Firebox
®
;
- a seam of high temperature mastic has
been inserted where the
fl
ue attaches and on
the smoke outlet collar;
i)
lower the previously inserted stainless steel
pipe until it
fi
ts into the Firebox
®
smoke outlet
collar.
Do this by hand in the space between Fire-
box
®
and the top of the inlet to the existing
chimney
l)
if Firebox
®
is ventilated, leave a space for
the fan power cord making sure it does not
come into contact with hot parts
m)
carefully close off the remaining space
between Firebox
®
and the edges of the inlet
to the existing chimney.
It can be closed off with a metal mantelpiece,
brickwork or
fi
re retardant plasterboard.
Leave a slight space between the closing
material and Firebox
®
to allow for expansion.
INSTALLATION IN AN EXISTING FIRE-
PLACE
WITHOUT
EXTERNAL AIR INTAKE
Check for the possibility of making a pit inside
the existing
fi
replace (Fig. A) by removing the
fi
re surface.
This pit must be big enough to hold the ex-
ternal air intake mechanism (Fig. A) and must
be connected to the outside by a duct with
cross-sectional area of Ø 80/200 cm
2
(ac-
cording to model) (Fig. B).
If it is not possible to do as described
above, place a 80/200 cm
2
external air in-
take as near to Firebox
®
as possible.
In this case, the mechanism is not used
and the lower Firebox
fl
ange must not be
removed.
Proceed with the installation as described in
the previous section from point "
e
" onwards.
INSTALLATION WITH A
NEW
, SPECIALLY
MADE COVERING
Position Firebox
®
according to the character-
istics of the new covering with which it will be
completed.
If the covering is produced by EdilKamin, you
will
fi
nd instructions for correctly positioning
Firebox
®
in the packaging.
Place the external air-intake mechanism
and connect the lower inlet directly with the
outside using a
fl
exible aluminium tube or a
specially made duct; Both having a minimum
cross-sectional area of 80-200 cm
2
(Fig. B)
(depending on model).
Place Firebox® onto the mechanism and
make sure the lower
fl
ange has been re-
moved to allow the
fl
ow of external air (Fig.
B).
Connect Firebox to the
fl
ue with a Ø 16 or Ø
20 cm pipe.
Complete with the chosen covering and in-
stall the kits for hot-air circulation (see follow-
ing instructions).
HOT-AIR CIRCULATION AND DUCTING
(Fig. D, page 26)
The air drawn from the outside through the
special mechanism (A) is mixed with air
drawn from the room through the lower grilles
(B). The mixed air is then heated in the rear
cavity and comes out into the room through
the upper front grille (C).
This ensures replenishment of the air which
leaves Firebox
®
through the
fl
ue during op-
eration and at the same time heats the room.
Alternatively, the hot air may reach the room
through an outlet connected to the holes in
the upper part of Firebox® (D) with Ø 14 cm
aluminium pipes.
The air circulation described above may take
place naturally by convection or with the help
of two fans (E) housed in the base.
If the hot air is channelled into rooms other
than the one in which Firebox
®
is installed,
it is necessary to ensure an air return to the
installation room through grilles at the bottom
of the walls or gaps under the doors.
The pipe diameter must not be less than 14
cm so that the air does not exceed a speed
of 5 m/s, thus avoiding irritating noises or ex-
cessive load losses owing to friction.
It is important that the path of the pipes is as
straight as possible.
Aluminium pipes may be hidden within the
ceiling or false beams, or built into walls; in
any case, they must be well insulated.
The ducting must be a maximum of 4 - 5 m
long for Firebox
®
with natural convection and
6 - 7 m long for Firebox
®
with forced ventila-
tion.
This length must be reduced by 1.2 m for
each bend and for each outlet owing to load
losses.

The product is supplied with two anti-corro-
sion discs (one on the outside and one on
the inside of the combustion chamber). They
must be removed during unpacking and di-
sposed of as normal waste.
