In places where the weather is very cold or there is risk of freezing, the expansion tank,
expansion input and output pipes should be insulated.
The input pipes connecting to the expansion tank should be assembled without turning
downwards and should steadily level up when going from the boiler to the expansion tank.
A hydrometer should be installed to the assembly in order to control the water level of the
system.
Make sure not to install units like valves, filters, check valve, etc. over the safety pipes
between the expansion tank and the boiler.
When water comes out of the messenger pipe, it means that the expansion tank is full and
the boiler has reached a specific pressure level. This should be checked at times when water
is pumped to the boiler from the main water supply.

These are containers
open to

and they should be
installed a distance from the top of the
pipe system for hot water systems or at
a distance from the radiator level at the
top.
For the manual feeding boiler, open
expansion tank must be used.
