7. PRACTICAL INSTRUCTIONS AND ADVICE FOR HEATING SYSTEM USE
- We recommend that you choose a closed system due to the risk of corrosion in an open heating system.
- All connections must be well sealed and fastened.
- Before commissioning, the complete installation should be examined with water with pressure of 2,4 bar.
- It is desirable that water is drained out from the system at least once because of the grime located in the
system.
- For an installation in which
only a stove “alfa term 20” is connected, we recommend expansion vessel from
18 (l) but not less than 12(l) which would be placed on returning water, as close as possible to the boiler, and
no block valve should be set between the boiler and the expansion vessel.
