3. Safety
3.1 CE certification mark
This appliance has been tested according to EN 13229-2001 and EN 13229-A2:2004 standards.
3.2 Safety instructions during installation
The installation of this wood fireplace may only be carried out by a recognized installer according to
applicable national and/or local standards and building regulations.
Take the necessary precautions using incombustible materials so that items in the immediate vicinity
of the appliance (curtains, floor, walls and so on) are not overheated.
Check that the fireplace is functioning correctly before commencing with the surrounding fireplace
finish. (5.2.2.1. Checking the fireplace)
3.3 Safety instructions for user
These wood fires radiate significant levels of heat. The entire outside of the fireplace becomes
extremely hot (the metalwork, glass in the door, surface and surround).
So, ensure that young children and older people always keep sufficient distance from the fireplace so
that they cannot come into contact with it, and provide a fireplace guard around the fireplace if
necessary.
Never let children operate the fireplace.
Make sure that flammable materials (wooden mantels, curtains, flammable liquids, furniture and so on)
are always separated from the fireplace by at least 0.8 m both above and around it.
Following installation, all visible parts of the fireplace should be considered as active heating surfaces
and therefore should not be touched when the fireplace is in use.
Touching these parts constitutes a risk of burns.
Do not use the appliance if the glass in the door is cracked or broken.
If defective, the glass in the door must be replaced immediately by a competent Metalfire installer.
This fireplace is only intended for additional heating, i.e. not for continuous use.
3.4 Safety facilities
The installer must take all measures required to prevent overheating of adjacent materials. These
measures must comply with national and/or local standards and regulations and the installation must
meet all (national and European) standards. Take the necessary measures by using fireproof and
insulating materials to prevent overheating of flammable materials in the vicinity of the fireplace. See
Table 1 for the minimum insulation thicknesses.
The heat radiation through the fireplace
window can be considerable. Therefore,
a distance of at least 80 cm must be kept
from flammable material.

5.5 Insulation
-Fitting additional insulation around the convection case, appropriate for such applications
(temperature range, fire safety, no dust emission) is compulsory.
-For insulating the fireplace, only Promafour 400 with 15 mm thickness can be used. This is a
solid panel having no loose fibres. Hence, no loose fibres can enter the convection current.
-Custom-made Promafour panels are available as an option.
-The installer must take the necessary measures in order to prevent overheating of
surrounding materials in accordance with the locally applicable standards.
-Profiled sections have been provided at the appliance where you can easily insert the
Promafour panels (photograph 7).
-At the time of building in, the minimum insulation thicknesses must be observed (refer to 4.
Technical specifications).

5.6 Flue gas duct
-The minimum height of the chimney for a comfortable fire is 5 m measured from the
connection nozzle to the top of the chimney excluding the rain cap.
-The appliance has been designed for a natural draught of 12Pa.
-The duct must be insulated thermally in order to avoid condensation and to improve the
draught.
-The connection must run 1m vertical before a change in direction can be made
-Changes in direction up to 45° are admissible with a maximum of 2 bends.
-Connecting under an angle of 90° is strictly forbidden.
-It is absolutely forbidden to connect 2 or more appliances to 1 flue gas duct.
-Close off flue gas ducts that are not used.
-It is recommended to install a rain cap because it is advantageous for the lifespan of the
appliance and the flue gas duct.
-The outlet and position of the chimney in the roof surface and with respect to surrounding
buildings is very important, and can only be carried out according to the rules that are locally
applicable.
-An oversized flue gas duct can have a negative effect on the good operation, and has a direct
influence on the efficiency.
-We recommend a rigid stainless steel pipe for connecting the appliance. The pipe is to be
insulated with a ceramic wool blanket.
-An excessive draught can be decreased by means of a draught regulator. A poor draught can
be improved using a flue gas fan.
-Please contact MF when you want to connect an appliance to a flue gas duct that has a
smaller diameter than specified in 4. Technical specifications.
-We refer to the table below for the minimum configuration of the flue duct, a change in
direction of 45° must be compensated by 1m additional in height.

5.7 Flue gas valve
-Every appliance is provided with an automatic flue gas valve. When the vertical sliding door is
opened, the valve opens automatically so that there will be no smoke emission when firing
with the door open.
-The flue gas valve can be adjusted in function of the chimney draught. The initial adjustment
can solely be carried out by Metalfire. Please contact your dealer.
5.8 Convection air
The appliance is fitted with a convection system ensuring heat recovery in the room. To that end, a
number of rules must be observed. In most cases, the convection functions in a natural way. As an
option, we offer an air fan for boosting the convection current.
-For connecting it, use non-combustible aluminium flexibles with 150 mm diameter.
-Make sure that the flexible duct has the same resistance (= length, diameter and number of
bends).
-In the case where connecting pieces are closed off or when there is a variation in resistance,
we cannot guarantee a uniform spread of the temperature.
-Keep in mind the nett cross-section of the grate when placing grates on the outlets. The
surface area must correspond to the connected flexible duct.
-Use only grates that cannot be closed.
-Mounting of the grate at a minimum distance of 30 cm from the ceiling so as to avoid
discolouration and deposits as much as possible.
-Always 2 connecting nozzles must be connected at the top of the appliance. The pre-cut
openings for the connection can be easily removed (photograph 8 and 9)
-The appliance is provided with sufficient connecting nozzles for allowing connecting it. They
are fixed to the convection jacket by means of a self-tapping screw (photograph10).
-Use below table to determine the number of flexible inlet and outlet connections according the
installed model.
