sections ( chapter 11 "Burner installation", page 49).

The flange with internal thread (R ¾") for the fill and
drain connection (Fig. 26, [2]) is installed at the rear
of the boiler.
Fit the fill/drain cock (customer to flow).
Close the flow and return connections (install the
flange with vent screw on the flow connections).

boiler flow connection.
