WATER CONNECTIONS
Before installing the boiler, thoroughly flush out all the
pipes of the central heating circuit. Connect the boiler to
the water supply with a shut-off cock upstream. Connect
the condensate drain pipe to a clean domestic water
drain in compliance with the relevant standards.
The water fittings have the following specifications:
Gas Gas supply 3/4" M
MI1
Flow to direct CH circuit, 1” M
RI1
Return from direct CH circuit, 1” M
MI2
Flow to first mixed CH circuit, 1” M
RI2
Return from first mixed CH circuit, 1” M
ACS DHW outlet 3/4" M
AFS DHW inlet 3/4" M
S
Condensate drain
Available as accessories:
RC
DHW recirculation 3/4" M
MI3
Flow to second mixed CH circuit, 1” M
RI3
Return from second mixed CH circuit, 1” M

Circuits filled with anti-freeze must be fitted
with water disconnectors. In this case, use
a long-life anti-freeze and anti-corrosion
product specially formulated for use in cen-
tral heating systems served by ALUMINIUM
boilers.
