DESCRIPTION
The appliance is composed of a number of cast iron parts fitted together with special overlap joints and sealed with refractory cement. The unit is held in place by
nuts and bolts ingeniously placed on the outside of the heating chamber.
The sheet metal fireplace joints are hermetically welded.
All the appliances work through the process of
intermittent combustion
.
HOW THE FIREPLACE AND INSERT WORK
•
FIREPLACE:
The fireplace has a built-in secondary air heat exchange system composed of fins on all the stove's outer surfaces. The energy that this draws from the fire is
propelled by the dynamics of the hot air in the chimney breast and immediately circulated into the room through the diffuser, or into adjoining rooms.
The fireplace gives off heat through:
- Radiation: heat radiates from all its cast iron and glass parts.
- Convection: air circulates within the chimney breast and is distributed into the room or nearby rooms.
•
INSERT:
The insert has a built-in U-shaped heat exchanger around the heating chamber, composed of:
- a horizontal cast iron casing box underneath, which takes in the ambient air on either side of the ash pan and underneath the fire.
- a vertical galvanised sheet metal casing box.
- a horizontal galvanised sheet metal casing box above.
The air circulates between the finned outer walls of the iron stove which act as radiators and
these sheet metal casings, drawing energy from the fire, and the ducts placed in the top
casing box propel it to both sides of the chimney breast and/or to other rooms.
The heating power of the INSERT is completed by:
- radiation: heat radiating from all its cast iron and glass parts.
- convection: the air circulates within the chimney breast and is distributed to the room in
which the insert is located.
CHIMNEY CONNECTION
FIREPLACES
INSERTS
NEVER ALTER THE DIAMETER OF THE VENTILATION DUCT
If a chimney connector is used, its full length must be visible, whether directly or through a
door or grating in the chimney breast.
It is also essential to ventilate the area between the top of the fireplace and the ceiling, either frontally or laterally, by means of gratings or diffusers with a cross-
section of at least 100 cm

INSTALLATION IN A NEW OR EXISTING CHIMNEY
The appliance can be inserted into any fireplace built of incombustible materials and in good condition.
The appliance must be installed in a floor resistant enough to support the appliance weight without problem.
It is important to place the air vent grill in such a way that it cannot become
obstructed.
No part of the existing masonry should nor may be removed to increase the space in
order to insert the appliance.
Any defect or deterioration in the fireplace masonry must be suitably repaired
before installing the appliance.
Openings and gaps between the exterior wall masonry and the fireplace masonry
must be permanently sealed with refractory mortar.
All materials on or within the walls (floors, walls, ceilings) around the chimney
that are combustible or could be damaged by heat must be removed if the
chimney is in contact with these walls.
The surface temperature of such walls should not exceed 50ºC in accessible areas or
65ºC in inaccessible areas.
The insulation required to achieve this should be of an adequate thickness of
incombustible insulating materials such as:
- Special high temperature rock wool with aluminium on one side.
- Ceramic fibres with aluminium on one side, with or without an air cavity.
The insulation work must be carried out with the greatest care.
An access point must be made before installation to allow future cleaning of the
flue connector and the chimney pipe.
FLUE
If necessary, the chimney and flue liner should be cleaned beforehand.
Check that they are air/smoke-tight and unblocked, do not curve too sharply; ensure that the flue liner and flue collar cross-sections allow for connection using a
chimney connector (starter pipe).
WARNING! Connecting more than one appliance to the same flue is forbidden.
A good flue liner must be made of materials that are not good heat conductors so that it retains the heat.
It must be leak-proof and the walls must be tested beforehand for air/smoke-tightness unless it is re-lined for connection to the fireplace.
The minimum flue size is
40 cm
2
(e.g. 20 x 20) for fireplace collars of
under 200 mm
or
62.5 cm
2
(e.g. 25 x 25) for those with a collar of over
200 mm.
