COMMISSIONING
INSTALLATION
Once the system is finally filled turn down the servicing valve for the ballvalve
in the F & E cistern to the point where the warning/overflow will cope with the
discharge arising from a ballvalve failure.
Cleansing Hot/Cold Water System Treatment
Fully flush and if necessary chlorinate the hot and cold water system in accordance
with the recommendations in the Model Water Byelaws and BS 6700.
Note: Incorrect chlorination will damage the plate heat exchanger so care must
be taken that the system is fully flushed.
Commissioning the BoilerMate control system
For maximum system efficiency the store thermostat must be in control of the boiler
i.e. the boiler cycles on the store thermostat and not on its integral thermostat. The
BoilerMate control system will automatically commission itself to match the actual
performance of the installed boiler. However the operation of the control system
should be checked as follows.
(a) Check that the BoilerMate front panel mode
rocker is in the ‘normal’ position. Put the
hot water control rocker in the constant
position and the central heating control
rocker in the off position.
(b) The boiler will not start i.e there will be no
240V ac start signal at BoilerMate terminal
‘SL-B’ until:-
• The heating programmer calls for hot
water /heating which will bring display
segment V1.1 on, and
• Store sensors are calling for heat which
will bring display segments H1.1 and H1.2
on (see opposite)
(c) Set the boiler thermostat to maximum and
commission the boiler as per manufacturer’s
instructions and ensure that the flow
temperature reaches more than 77
o
C before
switching off. Display segments H2.3 and
V2.1 will be on whilst the boiler is firing.
(d) Check and adjust the speed of the boiler
pump to provide a differential temperature
of about 11ºC across the flow and return
when the space heating is off.
(e) Check on the A.C.B. that the appliance
reaches a suitable temperature ie above
75ºC
