Connect The Central Heating Supply And; Return - Buderus Logano G234X Installation And Maintenance Instructions Manual

NOTICE: Risk of system damage due to high
temperature variations in the heating system!
B If the boiler is operated in conjunction with
an air conditioning system, it is essential to
ensure that the pipes for the refrigerant
fluid are connected in parallel with the
boiler system using suitable valves to
prevent the refrigerant from entering the
boiler.
B The pipe system of a boiler connected to
the heating coils of hot-air heating
systems that may be exposed to the
circulation of cooled air must be fitted with
a flow-control valve or some other
automatic system for preventing the boiler
water from circulating by gravity during the
cooling cycle.
NOTICE: Risk of system damage due to
leaking connections!
B Install the connection cables to the boiler
in such a way that they are not under
stress.

DANGER: Risk of fire from flammable
materials!
B Maintain a clearance of 2 inches (51 mm)
from pipes carrying hot water and
flammable walls in the installation room.
We recommend installing a dirt filter and a silt
clearance filter (accessory) in the boiler
return connection to reduce build-up of
debris on the water side.
Observe the local regulations for connection
of boiler systems.
