Preparations For The Installation Of The Combined Inlet-Outlet System; Wall Duct With Concentric Pipes; Roof Duct With Concentric Pipes; Fitting The Fire To An Existing Chimney - Dru SCENIC SL 70 Instructions D'installation Et Mode D'emploi

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. When correctly assembled, the blue
rubber sealing ring inside the pipe should be visible from
the top.
• 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 1.5
metres of pipe must be fitted vertically. 1 metre for a
maximum of 2 metres horizontal pipe, and 1.5 metres for
a maximum of 4 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.
• 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 concentric
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.

INSTRUCTIONS FOR INSTALLATION
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 position
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
properly.
• 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.
The fire can be fitted into an existing chimney providing
that the chimney / flue dimensions are 150 mm or more.
A special flue kit is required, which can be obtained from
Drugasar or a Drugasar agent. Do not use any other type
of flue system for this.
