NOTE:
The calculated worked example includes
all the necessary ducting components to
complete the installation and has result-
ed in a total system pressure drop of 90Pa
at 90m3/hr mass air flow rate. This is ac-
ceptable as the pressure drop is below the
maximum permissible allowed. Only use
ducting components that have available
pressure drop values.
6.8
Ducting Installation
When installing the air ducting ensure the Edel is situated
on the tripod provided and note the correct positions for
installing the air connections as illustrated in Figure 9.
Dimplex offer a basic vent kit is provided with the prod-
uct to accommodate installations as per 6.8.1 and 6.8.2.
Should it be necessary to install the product further away
from the nearest outside wall the vent extension kit is
required. The extension vent kit part number is noted on
Section 8.7.
NOTE: For installations with longer air duct
runs, the total pressure drop must be
considered and the ducting components
sourced and installed correctly by the
installer.
6.8.1 Direct access
Figure 10: Direct access installation
1. Cut the Ø125 PVC pipe to (X + 25 mm), X is the dimen-
sion reference in Figure 10.
2. Glue the pipe into the opening in the wall.
3. Position the Ø125 wall joint terminal.
4. Pass the assembled air duct nozzle through the wall
from the outside.
5. Direct the air duct nozzle upwards as indicated on the
diagram to ensure rain or moisture do not enter the noz-
zle.
6. The Ø125 PVC pipe should overlap by about 25mm on
the inside wall.
7. Mark the direction of the air duct nozzle on the inside
by marking the top of the Ø125 PVC pipe.
8. Glue the wall flange onto the Ø125 PVC pipe, and
pressing it against the inside wall at the same time.
9. Cut the Ø80 PVC pipe to (X + 225mm).
10. Remove the cover parts from the insulated elbow
(length 355mm).
11. Insert the Ø80 PVC elbow into the base of the insulat-
ed elbow and affix it to the Ø80 PVC pipe (apply a bit of
silicone so that the assembly stays put together).
12. Fix the other end of the Ø80 PVC elbow into the air
duct nozzle.
13. The insulated elbow should be fixed into the wall
flange at the same time.
14. Slot the Ø80 PVC elbow into the appliance's air outlet,
and the insulated elbow into the air inlet.
15. Put the cover parts back onto the insulated elbow.
