The boiler does not normally need a bypass but at least some radiators on the heating circuit, of load of at least 10% of the
minimum boiler output, must be provided with twin lockshield valves so that this minimum heating load is always available. See
note regarding thermostatic radiator valves on Section 1.13.
Note. Systems incorporating zone valves which could completely cut off the ow through the system must also include a bypass.
BALANCING
1. Set the programmer to ON.
Close the manual or thermostatic valves on all radiators, leaving the twin lockshield valves (on the radiators referred to above)
in the OPEN position.
Turn up the room thermostat and adjust the lockshield valve to give an uninterrupted ow through the radiator.
These valves should now be left as set.
2. Open all manual or thermostatic radiator valves and adjust the lockshield valves on the remaining radiators, to give around
20
o
C temperature drop at each radiator.
3. Adjust the room thermostat and programmer to NORMAL settings.
