· Connection to the gas main (See Page 12 diag. 1-14B ). Make sure that the regulating equipment does not
become twisted during connection and that no unnecessary tension develops. Ensure the accessibility of
the connecting points for the various components. Check the gas tightness of the connections after they
have been made. Connect the pilot light pipe and the thermocouple [(J) and (K) respectively] to the gas
block (A), taking into account the maximum fixed length of the wires for the thermocouple and spark ca-
ble. (See Page 14, diag. 6-A). The spark cable (G) still has to be connected to the spark plug of the pilot
light burner.
NB. The spark cable has to be connected to the spark plug in such a way that there is no spark-over to iron
parts anywhere else than on the pilot light burner. Connect the flexible gas pipe to the radiator coupling in
the control box. ( See Page 12 diag. 1-14C) and then to the ø 8 mm copper pipe on the bottom of the appli-
ance beside the burner tray ( See Page 12 diag. 1-4) with the compression coupling already fitted. Ensure
that the gas pipe is free of dirt and sand.
· Fit the restriction sheet. ( See Page 14 diag. 7 )
NB. The fitting of a restriction sheet depends on the duct situation and so you should first read Section 5
“Concentric duct system” on Page 8.
· Mixing the incandescent granules and incandescent material ( See Page 15 ). Open both bags and put their
contents into the A4 grip-seal bag (containing these instructions ). Shake to mix thoroughly. Scatter the
entire contents over the burner (2) and the bottom of the combustion chamber, distributing it equally over
the surfaces. Ensure that the injection units of the burner are free of incandescent material.
( See Page 15-A )
· Position the log set as shown on Page 15. Do this with care, since soot may be formed if the log set is
wrongly positioned.
· You finally position and fit the glass, the glazing beads and the front in the reverse order as to how you
dismantled them.

5.0 Concentric duct system
The concentric duct system consists of an inner duct of 100 mm in diameter and an outer duct of 150 mm in
diameter. These ducts are concentrically arranged. The combustion gases are extracted via the inner duct,
while fresh air for combustion flows in via the space between the inner and outer ducts. The concentric duct
system enables various connections.
Through the roof and through the external wall.
The route for this system can be laid out in various ways, but there are several important conditions.
· The total permitted vertical duct length is a maximum of 12 metres (the sum of the duct length and the ef-
fective lengths of the bends).
· The horizontal duct length for a roof outlet must not exceed 5 metres, measured between bends, unless
otherwise stated.
· 90° bends have an effective length of 2 metres.
· 45° bends have an effective length of 1 metre.
· The outlet can be placed at any arbitrary position on the roof surface or external wall (inlet and outlet in
identical pressure areas) but must satisfy current regulations.
