INSTALLING THE COOKER INTO THE SISTEM FOR WATER HEATING
- For water supply and drainage in condominial (central) heating system are provided
connections to the boiler 1 ".
- Cooker can be installed on an indoor or outdoor central heating system.
Installation on closed central heating system
One of the aspects of mounting installations is depicted on figure 7a.and 7b.
.
–
The safety valve must be placed close to the boiler and must be set to a maximum
pressure of 3 bar (boiler is tested to 4 bar). The connecting line of the safety valve must be
as short as possible and must not have the possibility of closing. In this connecting line also
there must not be any single valve or any other fitting.
–
Closed expansion vessel is placed close to the boiler and has a short security line.
The volume of this vessel is determined by the capacity of the boiler where the ratio is 1kW:
1l.
–
The installation of the safety fuse of the boiler it's necessary. We highly recommend a
Caleffi 544 thermal fuse.
It is required the installation of a four-way mixing valve at certain place (Figure 6a and
7a) or a tubing pipe contact thermostat (Figure 7a and 8a), set to 55 ° C. Their installation is
required for the prevention of condensation on the walls of the boiler in the furnace furnace
(condensation boiler adversely affect the service life of the boiler and on the performance of
the product by creating a resin on the walls of the boiler, which represents an insulator so the
product does not have declared characteristics).
