4.6. PLUMBING CONNECTION
MCZ shall not be held liable for damage due to
incorrect connections or connections made by
unqualified personnel
IMPORTANT !!
The water system must be connected and the perfect
seal of the boiler must be checked also when the fire
is lit, before cladding the fireplace stove.
Failure to comply with the installation instructions
shall make the product guarantee void and lift MCZ
from any involvement concerning any damage to
people and objects.
In light of the above, MCZ shall not be held liable for
any possible break of the cladding in case the
compulsory preventive operating checks are not
performed.
To minimise the formation of limescale in the ducts,
in case of hard water being used, it is advisable to
install a softener filter.
4.6.1. Water characteristics
The characteristics of the water used to fill the system are very
important to prevent the build-up of mineral salts and the formation of
incrustations along the pipes, in the boiler and in the heat exchangers.
Therefore, please GET YOUR PLUMBER'S ADVICE
CONCERNING:

Hardness of water circulating in the system, to prevent
problems of incrustation and limescale, especially in the
domestic water heat exchanger. (> 25° French)
 Installation of a water softener (if water hardness
exceeds 25° French)
 Filling the system with treated water (demineralised).
 Possibly providing an anti-condensation circuit.
 Installation of plumbing bumpers to prevent banging
along the fittings and pipes.
If you have very extensive systems, with a large amount of water, or
which require frequent refilling, the installation of water softening
systems.
It should be remembered that incrustations
drastically reduce performance due to low thermal
conductivity.
