When installing a safety valve pay attention to the direct connection to water supply and sanitation, as well
as the fact that the valves (taps) must always be open
Note: The installation of heating and commissioning of the entire system should be entrusted exclusively
technician who guarantee the correct operation of the entire heating system. In case of bad design of the
system and possible mistakes while works by such person, a complete financial responsibility shall be borne
solely by that person entrusted with the installation of heating systems, not manufacturer or of the boiler.
Important!
Installing the stove needs to be executed expertly face at a reasonable project. Construction of the stove
allows you to connect to the closed or opened heating system. All connections must be well sealed and
fastened. Prior to commissioning, the complete installation must be tested with water at a pressure of 3 bar.
When installing a safety valve pay attention to the direct connection to water, sewer, and that valves
(faucets) should always be open.
It is required the installation of a four-way mixing valve at certain place (Figure 7a and 8a) or a tubing pipe
contact thermostat (Figure 7b and 8b), set to 55 ° C. Their installation is required for the prevention of
condensation on the walls of the boiler in the 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).
Instalation on closed central heating system
One of the aspects of mounting installations is depicted on figure 7a.and 7b.
- Safety valve must be installed in the vicinity of boiler and must be adjusted for pressure of max. 3 bar.
External guide of safety valve must be as shorter as possible and may not have possibility to be closed.
Within this guide, also, there may not be single valve or any other armature.
- Closed expansion vessel is to be mounted in the vicinity of boiler and its safety guide is short. Volume of this
vessel is determined according to the capacity of boiler and regarding ratio 1kW:1l.
- Installation of thermal valve in its provided place on the boiler is mandatory. We recommend thermal valve
