2.29 GENERAL CHECKS
WATER CIRCULATION SYSTEM
1.
With the system COLD, check that the initial pressure
is correct to the system design requirements.
For pre-pressurised systems, this should be 1.0 bar.
2.
With the system HOT, examine all water connections
for soundness. The system pressure will increase
with temperature rise but should not exceed 2.5 bar.
3.
With the system still hot, turn off the gas, water and
electricity supplies to the boiler and drain down to
complete the flushing process.
Note:
A flushing solution should be used during the
flushing procedure. Flushing solutions: Fernox F3
or DS40, Sentinel X300 (new systems) or X400
(existing systems).
4.
Refill and vent the system (see Section 2.15), add
inhibitor, clear all air locks and again check for water
soundness.
5.
Reset the system initial pressure to the design requirement.
WATER TEMPERATURES
Temperatures can be selected using the CH and DHW knobs.

6.
Balance the system. Refer to Section 1.18.
7.
Check the condensate drain for leaks and check that it is
discharging correctly.
8.
Finally, set the controls to the User’s requirements.
Notes.
1. If the pump has not operated in the last 24 hours it will run
briefly to prevent seizure
2. If the diverter valve has not operated in the last 24 hours
it will be operated briefly to prevent seizure. These two
operations will not occur at the same time.
