separate zones, must have a common return connection
to the distributor tube.

3.
Screw the supplied boiler thermostat pocket into the
appropriate front section tapping, using an approved
jointing material. Refer to Tables 7 and 8.

Connect pipe fittings to the rear tappings and plug any
unused tappings.
