CS + BODY THERM 160
ASSEMBLY INSTRUCTIONS
a) Place the boiler body over the heater: line up the two slots on the rear beam with the two M10 holes on the
upper heater panel and fix in place with two M10 x 45 screws and relative flat washers.
b) Fit the boiler shell: follow the instructions:
Replace ½ G single probe holder in the boiler with corresponding one for 3 probes which is included in the
accessories.
c) Carry out the water system connections between boiler and Domestic hot water tank (DHW tank) as follows:
c1) Screw the two 1” x 3/4” M/F reductions (pos.11) onto the heater inlet and heating outlet couplings of the
heater, sealing with hemp or Teflon.
- with boilers CS 21-26-30-35 only:
screw the 1” x 1” MM nipples (pos.12) onto the connections delivery, sealing with hemp or Teflon.
- with boilers CS 44-52-70 only:
screw the 1”1/4 x 1” MF nipples (pos.18) onto the boiler delivery and return couplings, sealing with
hemp or Teflon.
then screw the 1” x 1” MM nipples (pos.12) on these reductions, sealing with hemp or Teflon.
c2) Screw the 1” T-connector (pos.2) onto the nipple (pos.12), sealing with hemp or Teflon.
c3) Insert the 1” insulated sheath on the 1” x 1” flex hose (pos.16), cutting off any excess length.
c4) Screw the 1” x 1” MM flex hose (pos.16) onto the T-connector (pos.2) as illustrated, sealing with hemp or Teflon.
c5) Screw the 1” x 1”1/2 ball valve (pos.3) to the other end of the delivery flex hose (pos.16), sealing with
hemp or Teflon.
c6) Screw the 1” x 1” MF elbow (pos.7) onto the 1” x 3/4” reduction (pos.11) on the heater heating inlet
(MB), sealing with hemp or Teflon.
c7) Screw the 1” x 1”1/2 ball valve with non-return (pos.6) to the other end of the above-mentioned 1” x 1”
elbow, sealing with hemp or Teflon.
c8) Fit the pump (pos.5) on the above-mentioned non-return valve (pos.6), interposing a 1”1/2 O-ring (pos.4).
Make sure that the pump is fitted the right way round (arrow pointing down as per enclosed diagram).
c9) Screw the ball valve (pos.3), already connected to the delivery flex hose (pos.16), onto the pump,
interposing a 1”1/2 O-ring (pos.4).
c10) Insert the 1" insulated sheath on the 1"x1" MM flex hose (pos.9) cutting off any excess length.
c11) Scew the insulated flex hose (pos.9) on the in-boiler heating system return and on the heater heating
outlet interposing the relative 1" O-ring (pos.8).
c12) Screw the 1/2” drain tap (pos.10) into the relative boiler housing, sealing with hemp or Teflon.
d) Fit the instrument panel (pos.17) onto the boiler with insertion of the adapter stay. See diagram code
0002721940 and make the electrical connections.
e) Make the electrical connections as follows:
e1) Connect up the boiler/burner power supply with a flexible lead having a cross-section of 2.5 mm
2
;
connect to terminals L, N and Earth on the MC terminal block.
e2) Make sure that the main power line, the relative fuse-equipped switch (indispensable) and any limiting device
are suitable for the maximum current absorbed by the burner and boiler.
e3) Take the 7-pole lead (6+Earth) with earth protruding from the instrument panel and connect it to the 7-
pole burner/boiler connection plug supplied with the burner.
e4) Take the 3-pole lead (2+Earth) with earth protruding from the instrument panel labelled TPC and connect
it to the 5-pole plug supplied with the heater.
e5) Check that no wires/leads are touching any hot spots; run the wiring between the external shell and the glass
wool insulating layer.
f) Fill the DHW tank and bring it up to pressure before filling the heating (primary) circuit.
g) Before starting up the system carry out water system testing of the boiler/Domestic hot water tank connections.
N.B. Check the cautions of the magnesium anode every 6÷12 months.
