1Introduction
The appliance can only be installed by a competent person in accordance with the Gas
Safety. We urgently advise you to read this installation manual properly.
This appliance complies with the guidelines for European gas appliances (Gas Appliances
Directive) and bears the CE mark.
2Safety instructions.
The appliance should be placed, connected and annually checked in accordance
with these installation instructions and valid national and local Gas Safety
(Installation and Use) Regulations .
Check whether the data on the registration plate are in agreement with the local
type of domestic gas and pressure.
The fitter is not permitted to change these adjustments or the construction of the
appliance!
Do not place any additional imitation logs or glowing coals on the burner or in the
combustion chamber.
The appliance has been designed for ambience and heating purposes. This means
that all surfaces of the appliance , including the glass, can become very hot (hotter
than 100 °C). An exception to this are the bottom of the appliance and the
controls.
Do not place any inflammable materials within a of 0.5 m. of the radiation of the
appliance and ventilation grills.
Due to natural air circulation of the appliance, moisture and volatile components
from paint, building materials, floor coverings etc. that haven’t yet set, can be
drawn through the convection system and can be deposited on cold surfaces as
soot. That is why you should not use the appliance shortly after a renovation.
The first time the appliance is switched on, Let the fire run on maximum setting for
several hours so that the lacquer coating will have an opportunity to set and
possible vapours released can be safely removed by ventilation. We advise you to
be outside the room as much as possible during this process!
Please note that:
1. all transport packaging should be removed.
2. children or pets should not be present in the room.

3Installation requirements
3.1 The fire
The appliance must be built into an existing or a newly to be constructed false
chimney breast.
In appliances with flexible gas pipes, the gas control valve is mounted to the right
side of the fire for safe transport . Unscrew it and mount it at a distance of max. 30
cm behind the access door.
The receiver which has been attached in a transport holder (see fig.1.6 A) to the
side of control valve bracket, can now be slid onto the top of the control valve
bracket. The transport holder can be removed now.
3.2 False Chimney breast
The false chimney breast must be constructed of an non-combustible material.
Always ventilate the space above the appliance by means of the grills or a
comparable alternative with a minimum air supply of 200 cm².
For the finish, use special stucco (min. 100°C resistant) or glass fibre wallpaper to
prevent discoloration or cracks etc. Recommended drying time: for plaster is a
minimum of 24 hours per mm of coat applied.
The false chimney breast and its construction may not rest on the appliance
3.3 Requirements flue system and outlets
You should always make use of the materials prescribed by Faber International Ltd.
Only by using these materials can Faber International Ltd. guarantee a proper
functioning.
The outside of the concentric flue material can reach a temperature of
Approx 150°C. Make sure of proper isulation and protection in case of transit
through combustible wall or ceiling constructions. And observe sufficient distance.
Make sure that the concentric flue materials are bracketed every 2 metres when
they have an extended length, so that the weight of the flue material is not resting
on the appliance itself.
You may never start with a cut-down concentric pipe directly on to the appliance.

L

3.4 terminals
The flue outlet can end on an external wall or a roof . Check whether the outlet desired
by you complies with local requirements concerning good function and ventilation
systems .
For a proper functioning the terminal should be at least 0.5 m. away from:
Corners of the building.
Roof overhangs and balconies.
Eaves (with the exception of the roof ridge).
4Preparation and Installation instructions
4.1 Gas connection
The gas connection must comply with locally valid standards.
We advise Pipe work from the meter to the appliance must be of adequate size., with near
the appliance a gas isolater tap that should always be accessible. Place the gas connection
in such a way that this is easily accessible, and that before service, the burner unit can be
disconnected at all times.
4.2 Electric connection
If an adapter is used for the power supply, then a wall socket 230VAC – 50Hz must be
mounted in the close neighbourhood of the hearth.
4.3 Preparation of the appliance

Accurate:
owith the rotating adjustable legs.
4.4.2 Suspended from the wall
The appliance can be mounted suspended from the wall with the use of the suspension
bracket and the Rawlplugs supplied (see fig.1.3). These mounting materials are
exclusively intended for use on walls constructed of brick or concrete. For walls built of
other materials, such as hollow bricks, consult a professional expert.
4.5 Mounting the smoke emission outlet materials
In case of a wall or roof terminal, the hole must be at least 5 mm bigger than the
diameter of the flue material.
Horizontal parts must be installed at a (3 degree) slope up away the appliance.
Build up the system from the appliance. If this is not possible, you should make use
of a adjustable pipe .
For fitting the system a ½ metre cut-down pipe should be used. Make sure the
inner pipe is always 2 cm longer than the outer pipe. Wall and roof terminal are
also shortened. These parts must be secured with a self tapping screw.
Do not insulate but ventilate bild-in flue material (approx.100cm2)
4.6 Building a false chimney breast.
Before constructing the false chimney breast we advise you to perform a function test with
the appliance as described in chapter 7 “checking the installation”

L

4.7 False Chimney breast
Construct the false chimney breast from non- combustible material in combination
with metal profiles or of brickwork / aerated concrete bricks.
Take the grills and the service panel (see fig. 1.1 an1.2 )into account. Place a
protective shield made of non- combustible material above the grills (see fig 1.1 A)
Always use a lintel if the chimney breast is constructed of brickwork. This should
not be placed directly onto the appliance
4.8 Frameless without optional decorative sheet
Construct the false chimney breast against the build-in frame (see fig. 1.1 B).
Keep a minimum margin of 3 mm between chimney breast and the appliance in
connection with the expansion of the appliance.
The depth of the recess has no influence on the removal of the glass.
4.9 Frameless with optional decorative sheet
Construct the false chimney breast around against the build-in frame (see fig. 1.1
B) apart from the lower half. Keep a minimum margin of 3 mm between chimney
breast and the appliance in connection with the expansion of the hearth.
The height of the lower half should correspond with the height of the groove(see fig
1.5 )
Place the decorative sheet on top the build-in frame.

Remove the front glass first.
Place the suction discs onto the glass
Remove the sealing cord from the groove
Slide the glass upwards now, so that the bottom edge is released from the groove.
Now gradually move the bottom edge of the glass forwards slantwise and lower the
glass into the opening between the build-in frame and the appliance. (see fig. …
and 2.5 , 2.6 and 2.7)
Now gradually move the top edge of the glass forwards and upwards out of the
appliance (see fig. 2.8 )
To replace the glass repeat the process in reverse order.
Remove all Fingerprints from the glass, these will be burned into it once the hearth is
used.
6Plaatsen van het decoratiemateriaal
It is not allowed to add different or more materials to the combustion chamber.
Always keep the pilot burner free from decorative material!
Do not toss all the decorative material onto the burner all at once, as the very fine dust
may block the holes in the burner.
6.1 Imitation logs
Spread the vermiculate preferably by hand over the tube burners in the burner-slot.
The surface of the pebbles may be very slightly elevated from the burner plate but
it should be level throughout the entire length.
Place the imitation logs according to instructions. (see fig. 3.1. or the instruction
card)
It is optional whether you apply chips to the combustion chamber or not. Prevent
chips from covering the burner, this has a negative effect on the fire image.
Start the pilot en main burner, according to the instructions in the user’s manual.
Assess whether the flame distribution is correct.
Place the glass and check the flame picture into the appliance
6.2 Pebbles
Remove the burner plates F (see fig. 3.2)
Place the pebbles over the burner and the bottom. Spread the pebbles evenly to a

double layer. The surface of the pebbles may be very slightly higher than the
burner tube ( see fig. 3.3)
Place the glass and check the flame picture into the appliance
7Checking the installation.
7.1 Checking the ignition of the pilot burner, main burner.
Start the pilot and main burner according to the instructions in the user’s manual.
Check whether the pilot light is properly positioned above the main burner and is
not covered by chips, an imitation log or pebbles.
Check the ignition of the main burner at full mark or low mark.
(the ignition should take place quickly and easily).
7.2 Checking for gas leakage.
Check all connections and joins for possible gas leaks by means of a gas leak detector or
spray
7.3 Checking the burner pressure and the pre-pressure
Check whether the burner pressure and the inlet pressure measured agree with the data
indicated on the registration plate
Measuring the inlet-pressure:
Turn off the gas control tap.
Open the pressure gauge nipple B (see figure 1.7 ) a few turns and connect a
pressure gauge hose to the gas control valve.
Carry out this measurement when the appliance is on at full gas mark and when it is
on the pilot light.
If the inlet pressure is too high you are not permitted to connect the appliance.
Measuring the burner pressure:
Only perform this measurement if the inlet-pressure is correct.
Open the pressure gauge nipple A (see fig. 1.7 ) a few turns and connect a pressure
gauge hose to the gas control valve.
The pressure must agree with the value indicated on the registration plate. In case
of deviations, get in touch with the manufacturer.

* Close the pressure gauge nipples and check these for gas leaks.
7.4 Checking the flame picture.
Allow the applaince to burn for at least 20 minutes at full and then check the flame
picture for:
1. Distribution of the flames
2. Colour of the flames
If either one or both points are unacceptable, then check:
The positioning of the imitation logs and/or the quantity of pebbles or chips on the
burner.
The connections of the Flue materials for leakage (in case of blue flames)
Whether the correct flue restrictor has been mounted
The outlet .
oWall terminal is installed correctly
oRoof terminal is fitted and sited correctly
The flue system is correctly calculated
8Instructing the client

oThe combustion chamber
oThe glass
oThe logs for possible fractures
oThe outlet
9.2 Replace:
oIf necessary the chips/embers.
9.3 Cleaning the glass
Most of the deposits can be removed with a dry cloth. You can use ceramic hob cleaner to
clean the glass.
Note: prevent fingerprints on the glass. these will be burned into it once the appliance is
used and cannot be removed anymore!
Carry-out the check-up according to the instructions in chapter 7 “checking the
installation’
10 Conversion to a different type of gas (e.g.
propane)
This can only be done by installing the proper burner unit. for this purpose get in touch
with your supplier.
Always mention the type and serial number of the appliance when ordering.

11 Calculation of flue system
The possibilities for the lengths of flue pipes and the possible restrictors have been recorded
in a table (see chapter 12 ) This table works with a vertical and a horizontal length.
To define the vertical length all lengths of flue pipes in a vertical direction should
be added up.
- The roof terminal always counts as 1 metre.
To define the horizontal length all lengths of flue pipes in a horizontal direction
should be added up.
- every 90° bend in the horizontal part counts as 2 metres.
- every 45° bend in the horizontal part counts as 1 metre.
- Turns from vertical to horizontal or vice versa are not reckoned in the
calculation.
- The wall terminal always counts as 1 metre.
If there is transit under 45° then the real vertical and horizontal lengths should be
calculated.
11.1 Points of particular interest:
In case of a wall terminal, the entire flue system including the wall terminal should
be constructed of 200/130 flue pipes.
In case of a roof terminal, the entire flue system should be constructed of 200/130
flue pipes , apart from the roof terminal, which should be constructed of 150/100
and should be connected by means of a reducer.
The maximum chimney length is 12 metres.
You can never start with a 90° or 45° bend from the appliance.
You should always start with 1 metre vertical if the horizontal transit is more than 1
metre.
You should never start with a cut-down pipe from the appliance.
