Commissioning and installation checks
Open the incoming stop valve and fill the domestic mains cold and hot water
systems, the BoilerMate appliance and central heating system. Check the whole of
the domestic hot and cold distribution systems for leaks, and repair if necessary.
Central heating systems should be thoroughly cleaned and flushed out before
installing a new boiler. During the final filling of the system, a chemical water
treatment inhibitor should be added to the primary circuit to control corrosion and
the formation of scale and sludge. Note the volume of the thermal store must be
included in the calculations of the amount of inhibitor required. The OV will the
combined volumes and the SP will be separate volumes. Please ensure that any
chemical inhibitor used is compatible with all types of stainless steel.
Check the water level in the top up cistern and if a ball valve is fitted adjust if
necessary.
If a ball valve is provided, turn down the servicing valve once the
system is finally filled to the point where the warning/overflow pipe will
cope with the discharge arising from a ball valve failure. If an overflow is not
provided ensure the temporary filling hose is isolated and removed from its
connection to the mains water supply.
Fully flush and if necessary, disinfect the hot and cold water system in accordance
with the recommendations in the Water Regulations and BS EN 806:1-5: BS EN
8558:2011. Please note that the whole of the domestic hot and cold water systems
including the appliance must be adequately flushed after disinfection. Failure to do
this may cause damage to the plate heat exchanger and other components in the
DHW system. In domestic installations disinfection is not normally required.
It is essential that all systems function properly for optimum performance. To achieve
this the flow rate from each tap should be checked and a suitable number of taps
run simultaneously to check the impact of this on the flow rate at individual taps.
We recommend that flow regulators are provided for each tap/terminal fitting
to ensure that the available flow is shared evenly - See Appendix A for further
details.
Check the Control System
Raise the BoilerMate thermal store to temperature.
During this process switch on the boost immersion heater and check it draws current
using a clamp meter. Check wiring if the immersion is not drawing current.
Check that the store thermostat and immersion thermostats are switching at 75
degrees and adjust if necessary.
Run water from any hot tap to check the temperature is between 50 and 55 °C at a
flow rate of 6-15l/min.
Check that the central heating system works by running it and ensure that the boiler
is fired on the BoilerMate OV when the store temperature falls. The boiler should
always fire when there is a central heating demand when a BoilerMate SP is fitted.
Turn off the central heating and the Boiler and the central heating pump should stop
running; if a pump delay timer is fitted then the boiler pump will continue to run. If
not the Boiler pump will also switch off.
If you have any doubts regarding the commissioning seek advice.
See the fault finding section of the manual for further assistance/details.
