Water Connections
The boiler has one return and two flow tappings, Rc (1 in
BSPT). The two upper tappings are the flow connections.
The return is the lower position tapping and is marked
RETURN. It is essential the flow and return pipes are
connected to the correct tappings.
Fully Pumped Systems
A 1in x 22mm threaded adaptor, compression nut and olive
are provided in the kit for the return connection.
Fit the 1 in x 22mm threaded adaptor into the lower
tapping marked RETURN, connect the pumped return
into the adaptor using the nut and olive.
Fit a 1 in x 22mm threaded adaptor into the higher tapping
position marked FLOW, connect the pumped flow into the
adaptor.
Fit a 1 in plug to the remaining connection.
Follow the instructions under 'System Details'
regarding the vent pipe and cold feed.
Overheat Thermostat
For systems requiring an overheat thermostat, a modification
kit is available. The flow pipe arrangement for this type of
