8.1.3 The terminal outlet (PN 60 50712 300) of thick
wall aluminium pipe supplied must be fitted in
a horizontal plane and be placed so as to fit
exactly between the elbow on the combustion
fan and the outlet terminal hole with sealing
ring.
If required this terminal outlet must be cut to
length in order to respect the dimension
75.0mm (fig. 8).
However, when the depth of the control
compartment exceeds the value E indicated in
table 2, a seamless duct
∅
100 or
∅
130 of
thick wall aluminium and a sealing ring are to
be used to extend the length of the terminal
outlet (PN 60 50712 300). The absolute
maximum allowable extension to the
protection cap (standard length 300mm) is
700mm.
8.1.4 Attention must be given to properly seal the
controls compartment from the enclosure for
the main air stream (duct channel).
This sealing should be appropriate to avoid
any leakage of air from controls compartment
into the duct channel and vice versa.
NOTE: FLUE ARRANGEMENTS OTHER THAN
THOSE DESCRIBED AND SUPPLIED WITH THE
HEATING MODULE ARE NOT PERMITTED
8.1.5 A gas service inlet (PVC) sealing ring is also
provided for the appliance for size Rc 3/4 or
size Rc 5/4.
The hole size required for the seal ring in the
casing is 50 or 75 mm diameter. The
provided sealing ring fits for 1mm thick
panels.
All cables and wires passing through the
casing of the burner/controls section should
be
via
strain
relief
bushings.
It is recommended that sealing is
accomplished by the use of the sealed ring
type.
Connections between the burner module
controls compartment must be effectively
sealed from the appliance air-stream so the
pressure within the compartment remains
neutral.

9.1.1 The DJL Modules are provided with flue
outlets sized as per table 4:

9.1.2 If the DJL model is to be installed as a
room sealed type C12 or C32 appliance,
the burner and controls cabinet must be
sealed so as to ensure air leakage does
not exceed that stated in table 5.
9.1.3 The heating modules are delivered with
all parts necessary to properly seal the
combustion circuit.
Included with the heating module are:
- 90° elbow with sealing ring
PN 60 50733 130 (dia 130) or PN 60
50733 100 (dia 100)
-
gas tube sealing ring
(PN 06 22783 125) (3/4”) or PN 06
22783 054 (1 ¼”)
- 2 ‘teflon’ sealing rings
PN 06 22786 134 (dia 130) or PN 06
22786 104 (dia 100)
As shown in figure 11a these sealing
rings must be fitted in the outer casing to
properly seal around the combustion air
inlet pipe and the flue outlet pipe. The
centre distance between the pipes must
be respected as per table 6 and the flue
outlet must always be above the
combustion air inlet.
Figure 11b indicates the hole size
required (as shown in table 6) in the
outer casing and the position of these
holes relative to the mounting flange of
the RHC 8000(M) DJL heating module.
