Positioning the appliance in a new fireplace

Position the appliance at the required height and connect
it. Finish the fireplace.
Fitting the appliance tightly in a wall without a
fireplace (fig. 10)
Stand the fire on a plateau.
The plateau should be at least 10 mm lower than the
bottom of the hole so that the front overlaps the hole by
5 mm at the bottom. Connect the appliance.
Make a rectangular hole of incombustible and heat-
resistant material (e.g. promatec)

INSTRUCTIONS FOR INSTALLATION
fireplace to allow the heat to escape; if this is not possible
fit a convection connection set, available as an accessory
from your dealer.The heater can also be installed in a
corner, see fig. 1 for the space this requires.

Mantel iron

An L-shaped mantel Iron can be ordered from your
installer.The mantel Iron, intended to support the
brickwork above the fire.This enables a stress-free
installation of the appliance. Fit the mantel iron as
illustrated in fig. 2, allowing 5 mm between the top of the
appliance and the bottom of the mantel iron, so that the
packing cord provided seals adequately. Make sure that
the front of the heater (without the decorative facing)
and the front of the mantel iron are flush. Fitting the
decorative facing will hide the mantel iron from sight.

Convection connection

The convection system of flexible pipes will enable the
heat to be spread to every corner of the room.The
connection materials can be ordered separately from
your dealer.
Possible connections (fig. 3)
The external duct can pass through either the wall or the
roof; the connections to both supply and flue pipes
should meet the following requirements:
• The first metre of pipe should always be installed
vertically.
• The horizontal length of pipe must never exceed 4 metres.
• The maximum length of vertical pipe is 12 metres.
Allow 2 metres for a bend of 90° and 1 metre for a 45°
bend.There is no need to allow for the length of the wall
or roof duct.
The maximum total length is the sum of the pipe lengths
plus the equivalent length for the bends (see the four
examples in fig. 3).
The roof duct set, the supply and flue pipes, the
concentric pipe and bends are packed individually and
supplied together with a clip binding with sealing ring.Tile
flashing or adhesive flashing is also available for use with a
duct through a slanting or flat roof respectively.
NB: This appliance may only be installed using the flue
material ø150/ø80 supplied by DRU.This has been
approved together with the appliance to comply with all
requirements. DRU cannot guarantee that the appliance
will work correctly and safely if alternative installation
material is used.
Preparations for the installation of the
combined inlet-outlet system
• Select the required connection from the options shown
in figure 3.
• Erect the concentric pipes from the heater up. If the
structural situation requires that the first section of the
concentric pipe system be built in, take special note of
