Preparations For The Installation Of The Combined Inlet-Outlet System; Wall Duct With Concentric Pipes; Roof Duct With Concentric Pipes - Dru COLOURLINE G31 Instructions D'installation Et Mode D'emploi

INSTRUCTIONS FOR INSTALLATION
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 com-
bined 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 concen-
tric pipes and the wall or ceiling.

Wall duct with concentric pipes

Ensure that the first metre of pipe used for the wall duct
is assembled vertically.
• 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.
• Now vertically connect one or more concentric pipes to
the heater outlet. Press well and fit the strip(s) of clip
binding.

• Place the bend on top of this, fit any horizontal concen-
tric pipes required, and make sure the connections are
gastight.
• Connect the wall duct to the bend or the horizontal
pipes and make sure that this connection is also gastight.

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.
• Determine the position of the appliance and the posi-
tion of the chimney.
• Drill a Ø 160 mm hole at the point where the chimney
is required.Through flammable material Ø 230 mm.
• Now vertically connect the concentric pipes to the
heater outlet. Press well and apply the clip binding.
• Determine the length of the pipes required and ensure
that the adhesive flashing or the universal tile fit proper-
ly.
• 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.
