out of the combustion chamber. Now position the heater as
required, allowing enough space around the heater for the
heat to escape. For effective heat dissipation, there must be
adequate ventilation above the heater. Once it is in position,
fix the appliance to the wall with the wall brackets and two
Rawlplugs provided, (see fig. 1). Use the Rawlplugs in the
bottom holes of the brackets, so that they will always be
accessible from the front.

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.The mantel iron
must not be fitted directly against the air chamber. Fit
packing cord here as well. 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.

INSTRUCTIONS FOR INSTALLATION
The external duct can pass through either the wall or the
roof.
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/ø100 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.
• 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
