5.6 Boiler assembly

• Remove the protective caps from the boiler
pipes.
• Hook the boiler on the support.
• Screw the cock on the boiler.
• Fix or weld the flared stub pipes, respectively
Ø 14 mm for d.h.w. inlet and outlet and Ø 18
mm for hydraulic system return, delivery and
gas.
Figure 5.3
• Install a shut-off valve on the d.h.w. inlet. The
purpose of the cock is to hydraulically isolate
the unit, making normal maintenance pos-
sible.
• If the hydraulic heating system is higher than
the boiler surface, cocks should be installed
in order to disconnect the system for mainte-
nance purposes.
