The flow from the pressure relief valve should be plumbed away.
A Tundish must be installed in accordance with Building
Regulations: G3.
9. Filling The System
Ensure the automatic air vent on top of the heat exchanger
is functioning correctly.
Open the filling loop valve and pressurise the system until 1
bar is showing on the pressure gauge. It may be necessary
after venting air from the heating system, to repeat this
operation in order to fill the system correctly.

The casing is supplied pre-assembled. Remove the front cover
first, then the top panel and then the bottom panel which has the
control panel assembly attached to it.
