Service Flap; Possible Connections - Dru SCENIC SL 70 Instructions D'installation Et Mode D'emploi

INSTRUCTIONS FOR INSTALLATION
Service flap (fig. 2c).
Make a hole of 285 mm x 194 mm (h x w) for the service
flap.
Fit the inner frame (1). If you are building a brickwork
chimney breast the frame can be built in at the same time.
For a chimney breast of any other material, glue/cement the
inner frame in place or fit it with four countersunk screws
Ex-works, the gas control block is mounted under the
appliance.
Remove the gas control block from the appliance.
To do this:
Undo the flexible gas pipe (spanner 17), the aluminium pilot
light pipe (spanner 10) and thermocouple 1 (spanner 10)
and carefully unwind the pipes, making sure there are no
kinks.

NB: The red wire of thermocouple 2 must remain
connected to the gas control. Fig. 2b shows how the wires
are connected to the thermocouple.
Now remove the gas control block.
Lead the pipes to the required position, making sure that
no dirt gets into them.
Carefully unwind the red and black wires of thermocouple
2.
Lay the gas control together with the wires of
thermocouple 2 in the direction of the control box.
Mount the gas control block on the brackets (2) on the
inner frame.
Connect the pipes to the back of the gas control block.
Make sure that the flexible hose and the aluminium pipe
connections are gastight.
First screw thermocouple 1 on by hand, and then tighten
one quarter turn with the spanner.
Place the remote control receiver in the tray (3). Make
sure the L.E.D. is pointing forwards.
Fit the outer frame with flap (4) to the inner frame using
the two self-tapping screws (5).
The outer frame can be fitted with the flap turning to the
left or the right, as required.
N.B.: Because of the temperature, the service flap should
be fitted as low as possible.
The feet of the appliance must also be taken into account
when installing the Scenic SL. Fig. 2a show the area ( * ) in
which the service flap can be fitted.
Possible connections (fig. 4)
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 fitted vertically,
except example 5 in fig. 4.
• The horizontal length of pipe should never be more than
4 metres and a wall duct.
• 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 5
examples in fig. 4).
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.
