3.2. Hydraulic coupling of the block to the installation
-
Connect the flow and return pipes of the installation.
The openings of the pipes are tapped at 2".
IMPORTANT:
-
The diameter of the flow and return pipes can not be reduced on a length of 200mm minimun.
-
Place the drain cock in the opening tapped at 3/4" on the front element of the furnace.
Saint Roch Couvin boilers are designed to function in hot water heating installations.
It is forbidden for the boilers to work
in thermosiphon (without circulating pump).
The circulating pump must be choose to ensure a difference of temperature between the flow and the return of minimum 5°C
and maximum35°C.
-
The recommended hydraulic diagram : heating circuit.
- After installing the cast-iron block, the boiler shall be
subjected to a water pressure of 4 = 5,2 bar (min. 4 bar), before
fitting the thermal insulation and the mantle. No leakage
must occur during the water test.
-
Positioning the bottom rear fixing plate (A) on the cast iron
block (on the rear section).
-
Using 2 M8 X 10 (DIN 933) screw, block the rear plate in its
position on the cast iron block.
-
Proceed in the same way for the other casing fixing plates:
the upper rear plate (B);
the bottom and upper front plates (C).

-
Place the insulation (D) around the heating sections, taking care not to let it get between the elements.
-
Bind it with the tapes (E).
-
Place the pre-cut insulation on the back side (F) (hydraulic connection and connection with the chimney).
-
Hold in place with the tapes (G).
3.4. Fixing the insulation
IMPORTANT : The hydraulic connections of the
boiler to the heating circuit must be made taking into
account the overall dimensions of the boiler casing.
