Figure 9: Controls compartment (side) panel for RHC 4000(M) RJL units
8.1.3
The terminal outlet (PN 60 50712 300 or 60 50712
130282) 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 1, a seamless duct
∅
100 or
∅
130 (for the M
range) of thick wall aluminium and a sealing ring
are to be used to extend the length of the terminal
outlet. 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 ¾.
The hole size required for the seal ring in the
casing is 50 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 dia 130mm.:
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 4.
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)
- gas tube sealing ring
(PN 06 22783 125 or 06 22786 054 (M units)
- 2 ‘teflon’ sealing rings
PN 06 22786 134 (dia 130)
- set of restriction rings
(only for 4000M units!)
as per table 3a.

Use of flue restriction rings
(only for 4000M
models).
To assure the efficieny of the M units
eventually a flue restriction ring needs to be
fitted in the outlet collar of the venter housing
(see fig. 11a). The diameter of the restriction
ring will be determined by the flue length as
indicated in table 3b.
