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.
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
the required method of assembly.
• The appliance has a coupling section; fit the first metre of
pipe onto this.
• Allow at least 5 cm between the outside of the
concentric pipes and the wall or ceiling.
Wall duct with concentric pipes
You must consider that for a wall duct, the first 1 or 0.5
metres of pipe must be fitted vertically. 0,5 metre for a
maximum of 2 metres horizontal pipe, and 1 metres for a
maximum of 3 metres of horizontal pipe.
• Determine the position of the appliance and the position
of the wall duct.
• Drill a Ø160 mm hole at the point where the wall duct is
required.Through flammable material Ø 230 mm.

Roof duct with concentric pipes
A duct through a roof can open out anywhere on the roof,
with an extension to the ridge if necessary. Depending on
which of the aforementioned options has been chosen, the
roof duct will be supplied with either adhesive flashing for
a flat roof or a universally adjustable tile for a slanted roof.

• Saw the outside pipe off at the length required.
• Connect the roof duct to the concentric pipes.
NB: Alternatively, you can fit the concentric pipes before
installing the heater. In that case the connection to the
outlet of the appliance should be made using a length of
pipe that can be shortened later.
