Directions for use and Installation Instructions
In dwellings with an operating extractor hood, this should be turned to the lowest
setting or turned off altogether. If the extractor hood remains in use, additional
ventilation must be provided in compensation. This will not only avoid poor
combustion, but will also prevent fl ue gases being sucked from the appliance
into the room.
Should creating an extra ventilation opening prove insuffi cient, it is then neces-
sary to fi t a fl ue gas fan.
3.3.2 Fitting in an existing chimney breast
• Remove the existing fi re basket or stoking stones and remove the shut-off
fl ap. The chimney must be intact and must not be damaged during fi tting. The
chimney breast opening must be big enough for a gap of 1 - 3 cm to be left all
round the appliance. Clad the chimney breast opening from the inside with a
ceramic wool fi reblanket or similar (see section 3.3).
• Extend the existing chimney so that it ends at the appliance’s smoke outlet.
To do this, use a fl exible, double-walled stainless steel chimney, for example.
• Slide the appliance into the chimney breast opening. Seal the smoke
outlet where it joins the chimney so that no soot can accumulate above the
appliance
under any circumstances .
• Level off the appliance.
• Fill any gaps around the appliance with a ceramic insulation wool fi reblanket
and position the frame (where supplied).
• Close the existing convection openings at the top side of the appliance.
