8175M & 90 79344 08 for 8200M)
- Gas tube sealing ring
(PN 06 22783 054)
The 90° elbow, sealing ring, terminal and the
combustion air inlet protection grill must be installed
according to figure 6.
All sealings must be correctly placed in the tubes to
avoid flowing back of combustion products to the
burner.
As indicated, the combustion air inlet protection grill
must be integrated in the side panel of the controls
compartment. The dimensions of the required
opening in this side panel and its position relative to
the mounting flange of the RHC 8000(M) RJL heat
exchanger enclosure are indicated in figure 7 & 8.
The air inlet protection grill must be installed in a
level plane and horizontally centred.
The minimum and maximum distances between the
axis of the flue outlet pipe and the top of the
combustion inlet grill are 250mm and 400mm.
Ensure the combustion inlet grill at the control door
panel is completely sealed to prevent ingress of
water.
It is forbidden to use the combustion inlet grill as
passage for cables or gas supplies. Ensure the inlet
grill openings are not obstructed.
Make sure the installation of the combustion inlet
grill is securely fixed.
The outlet combustion-sealing ring (dia 100 = PN 06
22786 104, dia 130 = PN 06 22786 134)
must be
installed in the fixed outlet panel of the air handler in
a hole with respectively dia 112mm or dia 142mm.
This hole must be located in the axis of the 90° flue
outlet elbow with a sealing ring of the RHC 8000(M)
RJL . The sealing ring fits for 1mm thick panels.
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.
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.
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
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.
