First firing
You should inspect the appliance for damage in transit immediately it has been delivered. If it is dam-
aged, you should report this without delay and as precisely as possible to your supplier. Your appli-
ance is coated with heatresistant enamel which can withstand extremely high temperatures. Burn the
fire on high during the first hours of use and ventilate the room well. The curing of the enamel may pro-
duce a smell/smoke, but this is harmless. Any marks on the glass can be best removed immediately
with glass cleaner.
Guarantee (See Page 27 and 28)

5. Installation instructions
General
The appliance is a completely sealed construction, which is to say that it can be used in chink-free, me-
chanically ventilated homes, without additional ventilation being required. The special concentric duct
system enables the natural discharge of flue gas and supply of combustion air from and to the appli-
ance. Various forms of outlet and routing are possible with this venting system, so that the positioning
of the appliance is flexible.
Attention
* The appliance should be installed, connected and inspected by a registered installer in accor-
dance with national and regional norms.
* The appliance should be inspected by the installer for gas tightness to gas products and combus-
tion products and for correct operation of the various components and functions.
* The venting system and the outlets in theexterior wall or roof surface must comply with the regu-
lations currently in force.
* The appliance is classified as a sealedappliance installed in a location without ventilator and with
a chimney loss in excess of 17% (non-condensing).
* To maximise the heat output of your fire when it is built-in a wall or surround, you can use the op-
tional convection set consisting of 2 ducts, grills and brackets.
Clearance to combustibles
* From the front and sides of the stove a clearance of 500 mm should be taken to curtains, drapes
and other Fabrics
Clearance to non-combustibles
* Construction materials for surround and mantels must be made of non-combustible material.
Attention: this include floor and ceiling
*When installing the appliance, you must maintain a minimum clearance of 20 mm from the wall at
all times.
Maintenance
* The appliance can be cleaned with a soft damp cloth. The appliance should be turned off immedi-
ately if something is spilled on it. The marks can be removed with mild soapy water once the ap-
pliance has cooled down. NEVER use an abrasive!!!
* Any deposit on the glass can be removed with glass cleaner.
* It is advisable to have the fire and the chimney checked and cleaned by an installer before every
heating season. If the special glass is broken or cracked, have it replaced immediately before you
turn the stove on again. In the heating season it is advisable to leave the pilot light on against
condensation in the appliance. If the stove will not be used for a longer period it would be wise to
shut off the gas gas-valve in the supply pipe.
Connection to the gas pipe
Ensure that the control equipment does not become twisted during connection and that no excessive
tension develops. Check the connections for gas tightness after installation. Connect the supply pipe at
the gas-valve with a 3/8” coupling and make sure that the gas pipe is free of dirt and sand.

Gas category: Natural gas or Butane/Propane. Type :C11 / C31. Safety: Thermo -electrical
* Nominal output depends on duct situation used.
7. Concentric duct system
The concentric duct system consists of a inner duct, 100 mm in diameter, and a outer duct, 150 mm in
diameter. These ducts are fitted concentrically; discharge of combustion gas is through the inner duct
and supply of combustion air to the appliance is between the inner and outer ducts. The wide range of
elements enables a flexible connection between appliance and outlet section.Various connections are
possible using the concentric duct system:
Through the roof surface and Through the exterior wall.
The route for this system can be constructed in various ways, but there are a number of important
conditions:
•Horizontal duct length for roof outlet must be no more than 4 metres, measured between the
bends.
•Total maximum duct length permitted is 12 metres (sum of duct length + nominal lengths of the
bends).

Page 17
•90-degree bends have a nominal length of 2 metres.
•45-degree bends have a nominal length of 1 metre.
•Assembly direction is very important.
•The outlet can be made anywhere in the roof surface or exterior wall (inlet and discharge in iden-
tical pressure areas), but must comply with the regulations currently in force.
The concentric duct system consists of the following components: ( see page 25 )
A. Concentric pipe. 25-50-100 cm J. Adjustable roof plate
B. Concentric 45° bend. K. Flat roof flashing aluminium
C. Wall bracket. L. Storm collar / rosette
E. Concentric 90° bend. M. Horizontal terminal eccentric
F. Wall band adjustable. N. Lead slope roof flashing 20°-45°
G. Adjustable length =250 mm O. Vertical terminal
H. Wall cover plate. P. Slope roof flashing 5°-30°
I. Locking band
Connection to concentric duct system
Note:
In combination with London surround;
Direct wall outlet-start with 1x 90° bend
Vertical outlet -start with 2x 45° bend
Direct external wall duct plus use 90° bend (see illustration 7, page 24).
Decide on the position of the appliance and connect up the wall duct set. The wall duct set will have to
be shortened if the appliance is being installed directly against the wall (cavity wall for example).
(Y=0.725 metres max.)
Exterior wall duct without bends (see illustration 8, page 24)
Always place a length of X=1 metre vertically on the appliance, directly followed by a 90-degree bend
and the standard length exterior wall duct set, Y=0.6 metres.
Exterior wall duct with horizontal bend (see illustration 9, page 24).
Always place a length of X=1 metre vertically on the appliance and the course can be continued with
one 90-degree bend (nominal length per bend is 2 metres). A maximum horizontal deviation of Y=4
metres can then be made. Ensure there is adequate slope and take the horizontal length of the bend
itself into account.
Note: In some situations the flue pipe should possible be placed close to the wall. Thus the 90° bend
can not make the shortest radius; to overcome this the hole in the wall for the 90° bend can be made
lightly oval shaped.
Roof duct without bends (see illustration 10, page 24).
A direct course without bends is possible to a maximum length of X=12 metres, measured from the
connection to the appliance. The minimum length is 3 metres. The outlet can be positioned anywhere
in the roof surface, whether flat or sloping; flue gas outlet and combustion air inlet are in the same
pressure area. Until 6 metres baffle -L -should be used (see page 13 ill.1 L) From 6 metres till 12 me-
tres baffle-M-and-L-should be used (see page 13 ill. 1 M-L

Page 18
Roof duct with 45-degree bends (see illustration 11, page 24).
Always place a length of X=1 metre vertically on the appliance. The route can then be continued with
two 45-degree bends until the maximum length of 12 metres is reached (Y+Z= 8 metres maximum).
The nominal length of the 45-degree bend is 1 meter. Until 6 metres baffle-L -should be used (see
page 13 ill.1 L). From 6 metres till 12 metres baffle -M-and-L-should be used (see page 13 ill. 1 M-
L)
Roof duct with 90-degree bends (see illustration 12, page 24).
Always place a length of X=1 metre vertically on the appliance. The route can then be continued with
two 90-degree bends (nominal length per bend is 2 metres) until the maximum length of 12 metres is
reached Take a maximum horizontal path of Y= 4 metres into account (measured between bends) and
ensure the slope is adequate. Until 6 metres baffle -L -should be used (see page 13 ill.1 L). From 6
metres till 12 metres baffle -M-and -L-should be used (see page 13 ill. 1 M-L)
Connection to conventional chimney (using the renovation kit)
The concentric connecting pieces for existing flues should be used for this purpose and the installation
instructions (apply for these separately) must be followed strictly. Until 6 metres baffle -L -should be
used (see page 13 ill.1 L). From 6 metres till 12 metres baffle-M-and-L-should be used (see page
13 ill. 1 M-L)
8. Construction of concentric Duct system
All components for this duct system and the corresponding guidelines for installation are given in sec-
tion 4. The assembly instructions are as follows:
Fitting exterior wall duct direct or indirect
Direct Connection.
•The outlet can be made in the exterior wall, but take nuisance in the neighbourhood into account.
The (Building Materials) Soil Protection Decree contains regulations for this. Also take care that
the wind pressure on the outlet is not too extreme (in very narrowalleyways for example), since
this may have a negative effect on the performance of the appliance.
•Make a round opening of155 mm in the exterior wall (keep an extra space of 50 mm around the
outer shaft if the exterior wall is combustible) and fit the exterior wall duct to the inside of the wall
with the wall plate. Check correct position of the wall terminal (see-TOP). The wall plate of the ex-
terior wall duct should be sufficiently well-sealed against the wall, on account of the possibility of
damp and/or flue gases leaking into the home.
•The course of the duct must meet the set requirements.
•The duct should be encased if necessary. Adequate fire-resistant measures should also be taken
if the duct is going to be fitted alongside combustibles.
Indirect connection
•Establish the position of the appliance and the outlet and start constructing the duct with the con-
nection to the appliance (with an indirect connection always 1 metre vertical first). Pay attention to
the fitting direction (black sealing rings pointing upwards) and use the clamping strips to connect
the elements together.
•Fit a 90-degree bend directly to the exterior wall duct and connect to the elements on the appli-
ance. Ensure that all connections are fully gastight.
•The =250 mm shorter able pipe can be used between bends or for connection to the appliance
and/or exterior wallduct.
•Use wall brackets to support the duct, if necessary.
Fitting roof duct
•The outlet can be anywhere in the roof surface (outlet and inlet in identical pressure area) and
must meet the regulations currently in force.
•A roof plate for flat roofs or a lead roof flashing for sloping tiled roofs can be used to make a wa-
tertight duct. Various bends can be made if required. The opening in the roof deck should be 5
cm bigger around to provide adequate fire resistance. Centring plates can be put against the roof
deck.

Pag.19
•NEN 6068 (determination of the resistance to spread of fire between areas) should be taken into account, in
accordance with the regulations in the (Building Materials) Soil Protection Decree. An encasement of fire-
proof material (e.g. Promatect 12 mm fire-resistant sheeting) is required 25 mm from the outer duct.
•Establish the position of the appliance and the outlet and start constructing the duct with the connection to
the appliance (always 1 metre vertical first). Pay attention to the fitting direction (black sealing rings point-
ing upwards) and use the clamping strips to connect the elements together. Ensure that all connections are
fully gastight.
•The course of the duct must complywith the set requirements;
•Take care when fitting the baffle; see “Connections for concentric duct system”.
•The ≤250 mm shorterable pipe can be used between bends or for connection to the appliance and/or roof
duct.
•Use 2 wall brackets on every storey to support the duct.

10.Putting the ceramic log set in place
First open the door (I). Then dismount the 4 glass ( C ) strips byloosening the M5 bolts.
* Before placing the ceramic materials (after service or inspection), Check the burner position. The burner
must be in correct position to avoid negatively influence of the flame pattern. Therefore check if the posi-
tion of the burner inlet is placed against the injector.
* Begin to scatter the ceramic grit ( placed in bag A ) at the left and the right site of the burner. round about
* Place the rest of the grit ( bag B ) on the burner.
* Fill the burning chamber with the decorative ceramic materials in that order as showed at the illustrations 3
till 8.
* As final scatter the ceramic flakes and the vermiculite in freedom of action.
*Check the flame pattern. Incorrect placed logs can negatively influence the flame pattern and the combus-
tion.
