4.3.       Installation 
The appliance is designed to be built into a new or existing chimney breast installa-
tion to provide space heating by radiant an convected heat. 
4.3.1.    To be built into a new chimney 
Build the new fire place around the appliance ensuring that no materials are built 
onto the appliance. Before constructing the fireplace facing wall (section between top 
of appliance and underside of raft lintel, fit a support lintel supported by the side 
walls and build the face wall using lightweight insulated building blocks backed with 
insulated panels. 
Never build directly onto the appliance. 
If flexible warm air ducts are to be used, install air grills at the outlet locations to 
allow passage of warm air to the specific area. 
Where the fireplace backs onto another room or is in the corner of a room, backing 
onto two rooms, grills van be fitted in the adjoining room or rooms. 
Never use grills made from plastic or other combustible materials. 
Ensure that the weight of the main chimney or chimney flue liners is not directly sup-
ported by the appliance. Flue liners must be supported independently of the appli-
ance.  
4.3.2.    To be built in a existing chimney 
The recess should be formed using an appropriately designed raft lintel to support 
the existing brickwork structure and chimney. The minimum clearance between the 
back of the appliance and the rear should be 1,5 cm. It is recommended to fix insu-
lating panels to the sides, back and top of the appliance. 
Never allow marble, granite or masonry to be in direct contact with the metal outer 
box of the appliance. Always use insulation. 
Prepare the opening ensuring that adequate support is provided for the chimney and 
existing brickwork structure. Ensure that enough height is allowed to adequately 
connect the appliance to the main chimney. If necessary, construct a raft lintel to 
form the top of the recess to support the chimney and surrounding masonry. This 
could be pre -formed with a minimum diameter 150 mm clearance hole incorporated 
for the connecting minimum diameter 150 mm flue pipe. 
If the recess is too wide, use insulated building blocks to reduce the width. 
Clean thouroughly the floor, wall and top of the recess. 
Stand the appliance in the recess and use a spirit level to ensure the unit is level and 
plumb. 
If an exiting masonry is installed, the appliance should be connected to the chimney 
using minimum diameter 150 mm,  stainless steel pipe. It is important to ensure that 
the connection to the chimney is carried out in such a way that any soot particles are 
allowed to fall un-hindered back into the appliance. 
Ensure that the weight of the main chimney or chimney flue liners is not directly sup-
ported by  the appliance. Flue liners must be supported independently of the appli-
ance.
