4.3 DOMESTIC HOT WATER MODE:
On opening a hot water outlet the boiler
automatically responds to fire the boiler and
supply the water-to-water heat exchanger with hot
water via the three port valve, located on the
hydro-block. The boilers electronic control unit
automatically modulate the burner’s output to
maintain the required temperature at the faucet.
Hot water will continue to flow until the faucet is
closed and the boiler automatically shuts down.
Note that the pump will continue to run for a
further 10secs to dissipate the residual heat from
the boiler.
4.4 DOMESTIC HOT WATER AND CENTRAL HEATING
MODE:
When heating demand is requested, power is on
and the thermostats are calling for heat, the
boiler will fire automatically. An integral pump is
then energised and hot water from the boilers
primary circuit is circulated around the central
heating systems pipe-work and radiators. When
the demand for central heating is no longer
present, e.g. the thermostat reaches temperature,
the burner will shut down and the boiler will
revert to stand-by, waiting to respond to the next
heating or hot water demand. The pump will
continue to operate for a short period of time to
dissipate any excess heat from within the boiler’s
heat-exchanger. If during the heating period
there is a call for hot water this will take
preference over heating. When satisfied the
boiler will then supply the heating demand as
required. Note there may be a 45sec delay
depending on how the boiler
’ s dipswitches are
set. See section 15.4 for details.
5.1 Installer Testing & Commissioning Tips
• The installer shall instruct the user in the operation
of the boiler, safety devices contained within the
boiler and instruction on how to re-pressurise the
system if the water pressure falls. The installer
should then hand over the instructions with the
Benchmark Logbook that has been completed.
• The user should be instructed to keep the
instructions in a safe place for servicing and future
reference.
• It is important to keep the boiler clear of dust during
the installation. In particular, do not allow debris to
enter the top of the boiler where the flue connection
is made. This may cause the fan outlet to get blocked
or combustion chamber to fill with debris and will, of
course, cause the boiler to fail to ignite on first
ignition. It is recommended that you check the fan
outlet before you light the boiler.
• Before you fit the boiler ensure that the pipe work
that you are installing is connected to the appropriate
connections on the boiler i.e. cold water pipe to cold
water inlet, hot water outlet to the hot water tap etc.
• Because the boiler is actually operated, at the end of
each production stage, a small amount of water is
retained within the boiler when packed. Please
ensure that you spin the pump rotor manually before
firing the boiler.
• It is important that the boiler must be used in
conjunction with a Hydroline approved flue and all
flue connections are correctly sealed.
• Remember to flush out the system, both cold and
hot, in order to remove the debris from the system.
This should be done particularly where boilers are
being fitted to existing radiator circuits.
• Refer to BS 7593:1992 for the details to clean DHW
and Central heating systems.
•
This boilers central heating output has been set to a
mid range position. However you may choose to
adjust this using potentiometer P2 to meet the
requirement of the system.
• Remember to release the small cap on top of the
auto air purge device on the pump, 1 turn, before
filling. This will ensure that air is removed as the
system fills.
• Do not use the pressure relief valve as a means of
flushing the system, please use the valve below the
pump. Discharging water from the pressure relief
valve may allow water to seep after you have left the
job, causing the boiler to lose pressure and debris to
collect on the seating.
• The boiler is fitted with inlet filters both on the cold
water inlet and the central heating return. If you are
unable to obtain hot water at an outlet
• it is likely that the cold water inlet valve filter has
become blocked, whilst blockage of the filter on
central heating return valve, the overheat thermostat
