Installation requirements
3.1 Appliance
This appliance may not be installed in a
chlorine-containing environment. (Pools
etc.).
This appliance must be built into an
existing or new false chimney.
For appliances with flexible gas pipes, the
control unit (fig. 1.0) is placed on the right
side of the crate for transport reasons.
Detach and mount it together with the
remote access door in as low as possible
position in the false chimney.
(To prevent damage to cables and pipes
during transport, they are bound together
by tie wraps. Remove these to ensure
proper operation of the appliance.)
If desired, a 2 meter pipe set is available
(article number 20900715).
3.2 False chimney
The false chimney should be of non-
combustible material.
The space above the fire should always be
ventilated using grids with minimal free
passage of 200cm² per grid.
The false chimney construction should not
rest on the build-in frame of the fireplace.
3.3 Discharge and outlet requirements
First, carry out a flue calculation (see chapter 11)
and place the right flue restrictor before installing
the outlet! (Generally a 30mm flue restrictor is
installed).
For supply and discharge always use the
prescribed and to be supplied Faber flue
materials. Please contact Glen Dimplex
Benelux B.V.. Only with use of these
materials Faber can guarantee proper
performance.
The distance to combustible materials
must be min. 50mm, calculated from
outside of the flue material (EN 1856-1
T600 N1 D VM – L20040 O(50)).
Outlets (fig. 1.2)
The balanced flue pipe for combined air supply and
discharge can use a wall terminal or a roof
terminal. Verify that the desired outlet meets the
local regulations regarding pollution and
ventilation openings.
Please note!
For proper functioning, the outlet must at
least be 0,5m away from:
Corners of the building;
9 <
<
<
<
Roof overhangs and balconies;
Roof edges (with the exception of the
ridge edge, see chapter 15).
C11, outlet via facade
Through a wall or façade, use a Faber wall outlet.
Depending on the flue calculation this can be
100/150mm or 130/200mm.
C31, outlet via roof
For a (flat) roof, use a Faber roof outlet with a
diameter of 100/150mm.
C91, existing chimney
For an existing chimney, use a Faber chimney
outlet with a diameter of 100/150mm.
In this case the existing chimney acts as air inlet an
inserted flexible stainless steel pipe discharges the
flue gas. The top (Faber chimney cover plate) and
the bottom (Faber chimney connection set) should
be airtight.
Depending on the calculated flue diameter, you
must use a flexible stainless steel pipe of
Ø100mm (article number AJ005503) or Ø130mm
(article number AJ005603) as specified by Faber.
For this, contact Glen Dimplex Benelux B.V.
Please note!
The minimum chimney diameter for a
130mm flexible stainless steel pipe must
be 200x200mm and for a 100mm flexible
stainless steel pipe and 150x150mm.
Don't connect more than one fire at the
existing chimney.
The chimney must be in good condition:
o
No leakage;
o
Well cleaned.
For more information about the connections to
existing chimney ducts, please request the
installation instructions "Chimney Connection Set".

Preparation and installation
instructions
4.1 Gas connection
The gas connection must comply with the
applicable local standards.
Please note!
Provide a flexible gas connection with at
least 0,5m extra length, so that the
control unit can be removed for
installation and service!
Calculate the gas pipe so that no
pressure drop occurs.
