Failure to wash the hydraulic system and introduce a suitable amount of
inhibitory liquid renders the unit's warranty null and void. Install shut-off valves
between the boiler and the heating system to isolate it from the system when
performing routine and/or extraordinary maintenance. Connect the boiler using
hoses to allow minor displacements and corrections during installation and
maintenance.
