In order to comply with the Terms &
Conditions of warranty, the system
must be hot-flushed to remove any
impurities (especially oil and grease)
from the pipes and radiators.
The CH pipes must be adequately
earthed. However, the appliance must
also be provided with an adequate
earth. Pipe work is NOT suitable for this
purpose.
Isolation valves must be installed on
the CH circuit in order to facilitate all
maintenance and service operations
where the boiler needs to be drained.
The boiler is supplied with a fittings kit
(see Figure 11) complete with isolation
valves and copper tails.
■
To prevent vibration and noise coming from
the system, do not use pipes of reduced
diameter, short radius elbows or severe
restrictions.
