BOILER INSTALLATION SEQUENCE
Central heating flow and
return pipework
(TURBOmax Plus)
Before connecting the heating circuit
to the boiler appliance, all pipework
and radiators must be thoroughly
flushed to remove any installation
debris.
● Connect the central heating flow
(6) and return (1) service valves to
the appliance (8 and 3) with the
washers provided (2 and 7) and
tighten the nuts. Ensure that the
valve spindles face downwards
and the drain points face to either
side of the boiler.
● Connect the 22 mm copper pipe
tails to the service valves as shown
in the illustration and tighten the
nuts.
● Connect the central heating
pipework to the flow (9) and return
(4) tails.
Pressure Relief Valve
Connect a discharge pipe not less
than 15 mm diameter to the outlet of
this valve.
The discharge pipework should be as
short as possible and installed with a
continuous fall away from the boiler.
The pipe should terminate in a
position which ensures that any
discharge of water or steam from the
valve cannot create a hazard to
persons in or about the premises, or
cause damage to any electrical
components or external wiring, and
the point of discharge should be
clearly visible (see diagram in plastic
bag).
