20 THE INSTALLATION OF THE DEVICE
1. VERZIÓ RU
THE BOILER ROOM
UNICAL GHISS boilers are allowed to be installed only in rooms where the replacement of the amount of air necessary for
the device according to the standards (ventilation) is secured, and which satisfy the fire-protection and other requirements.
There is no frost-protection function in these boilers, therefore, they can be installed only in rooms where there is no
danger of freezing!
THE CONNECTION OF THE BOILER TO THE EXISTING OLD HEATING SYSTEM
If we connect the boiler to the old heating system, the following instructions must be abided by:
o
The diameter and height of the chimney should satisfy the new requirements, should be of the necessary cleanness
and should provide the appropriate amount of draught.
o
The electric system should meet the regulatory requirements of
the boiler.
o
The pipes and fixtures of natural gas or tanked gas should
provide the amount and pressure of the fuel specified for the
boiler, according to the standards.
o
The closed expansion tank of the system should be of the
necessary size and pre-tensioning pressure so it can
compensate the changes in pressure of the system due to the
change in temperature.
o
The output of the heating circulation pump, as well as the place
and direction of installation should satisfy the new
requirements.
o
The hydraulic system should be free of air and sediment. This can be achieved through the thorough cleaning of the
system prior to connection. A better result can be achieved with chemical washing.
o
The requirements with respect to the chemical composition of the water of the system can be found in the table.
HYDRAULIC CONNECTION
The place of the connection of the heating system and water system for use to the boilers is illustrated by the following
