Heat Pure 105 Tunnel
•
8 flexible aluminium hoses Ø150 mm 4x 1.25 m long and 4x 0.62 m.
2 hoses of 2.5 m which must be divided in half, in order to get a total
of 4 hoses and 1 hose of 2.5 m which must be divided into 4.
•
16 hose brackets.
•
4 grills: outer dimensions 35 x 20 cm, recess dimension 33 x 16.5
cm, with 2 connection collars Ø150 mm each.
•
Mantle iron; this must be sawn to the correct size.
•
Roll of felt to create an expansion joint between the metal of the
mantel iron and the surround.
Method when using convection grills
Ensure that, at the base, there is sufficient supply for the cold convection
air from the room (see table below).
At the top connect the grills to the outlet openings of the warm
convection air (see table below).

Attention! When mounting the gratings, ensure they are placed in such a
position, that they cannot become blocked.
Method when using openings
If you do not want to use grills, openings at the top and base of the
surround (chimneybreast) are also sufficient. For through put openings,
see Table 2. These openings serve the same function as the gratings and
supply and extract the convection air. We advise you, to place tubes or
hoses on the outlet openings. This makes the convection system (just a
little) more powerful and the heat is guided more easily to the openings.
If you do not use the recommended convection set, this may
damage the Heat Pure by overheating. The result may be
soiled walls and ceilings in the room. There is always a risk of
discolouration to walls and ceilings, but this risk can be
considerably reduced, by correctly ventilating the room.
