5.9 Expansion vessel
The expansion vessel installed on the Thermal unit has the fol-
lowing characteristics:
Description U/M
SOLO HE EV
25 35
Total capacity l 10,0
Prefilling pressure
kPa 100
bar 1,0
Useful capacity l 7,0
Maximum system content (*) l 140
(*) Conditions of:
Average operating temperature 70°C (with high tempera-
ture system 80/60°C)
Start temperature at system filling 10°C.

CAUTION
– For systems with water content exceeding the max-
imum system content (as indicated in the table) an
additional expansion vessel must be prearranged.
– The difference in height between the relief valve
and the highest point of the system cannot exceed
6 metres. If the difference is greater than 6 metres,
increase the prefilling pressure of the expansion
vessel and the system when cold by 0.1 bar for each
meter increase.
5.10 Combustion chamber dimensions
The combustion chamber is a direct-passage type chamber and
conforms to the EN 303-3 standard Annex E. Its dimensions are
shown in the figure. An appropriate protective panel is applied
to the inner wall of the rear head on all models.
