INSTALLATION AND USE MANUAL

Chapter 4

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.
