SECTION 1 DESIGN PRINCIPLES AND OPERATING SEQUENCE
1.1 PRINCIPLE COMPONENTS
●A fully integrated electronic control board
featuring electronic temperature control,
continuous air/gas modulation, anti-cycle
control, pump over-run, self-diagnostic fault
indicator, electronic ignition with flame
supervision, & appliance frost protection.
●Cast aluminium mono-block heat exchanger.
●Low Nox burner with pre-mix.
●Two-stage gas valve.
●Pump.
●Expansion vessel.
●Pressure gauge.
●Safety valve.
1.2 MODE OF OPERATION (at rest)
When there is no demand for heating or hot
water. And the appliance remains inactive for a
periodof24hours,thepumpwillbeenergisedfor
afew momentstoprevent it fromseizing.Should
the flow temperature sensor fall below 7°C the
pump will be energised.
If the flow sensor temperature falls to below 3°C
theburnerwillbelitandtheappliancewilloperate
at the minimum output until the temperature of
the flow sensor reaches 10°C, whereupon the
pumpwillcontinuetoruninpumpover-runmode.
1.3 MODE OF OPERATION (heating/hot water
request)
Whenthereisarequestforheatviathetimeclock
and/or external controls, the pump will start and
the fan will be activated via the flow temperature
sensor. When the fan is sensed to be operating
correctly,theignitionsequencecommences.The
speed of the fan and therefore the output of the
boiler is determined by the temperature of the
water sensed by the flow & return temperature
sensors,consequentlyahightemperatureatthe
flow sensor results in a lower fan speed. As the
water temperature increases, the temperature
sensors–locatedontheflow&returnpipesofthe
boiler – reduce the fan speed via the electronic
circuitry.Dependingon the load,eitherthewater
temperaturewillcontinuetoriseuntilthesetpoint
is achieved or the water temperature will fall
whereby fan speed will increase relative to the
outputrequired.Whentheboilerhasreachedthe
set point, the burner will switch off. The built-in
anti-cycle device prevents the burner from re-
lighting for an adjustable period of time (factory
default is 3 minutes). When the temperature of
the flow sensor falls below the set-point, the
burner will re-light.
1.4 SAFETY DEVICES
When the appliance is in use, safe operation is
ensured by:
●a high limit thermostat that interrupts the
operation of the burner;
●adifferentialtemperatureprotectioncircuitwhich
interrupts the burner if the temperature
differential is inverted;
●a fan speed sensor which checks the correct
operation of the fan, thereby allowing safe
operation of the burner;
●asafetyvalvewhichreleases excess pressure
from the primary circuit.
●a condense pressure switch that will stop the
burner from operating should the condense
trap become blocked.

around the appliance, carefully remove all pro-
tectivepackagingfromtheappliance,andlaythe
accessories etc. to one side.
4.4 PREPARATION FOR MOUNTING THE
APPLIANCE
The appliance should be mounted on a smooth,
vertical,non-combustiblesurface,whichmustbe
capable of supporting the full weight of the
appliance. Care should be exercised when
determining the position of the appliance with
respect to hidden obstructions such as pipes,
cables, etc.
When the position of the appliance has been
decided–usingthetemplatesupplied–carefully
mark the position of the wall-mounting bracket
(see fig. 6) and flue-hole (if applicable).
4.5 FITTING THE FLUE
The top flue outlet permits both horizontal and
vertical flue applications to be considered,
alternatively, the Vokera twin flue system can be
utilised if longer flue runs are required.
4.5.1 CONCENTRIC HORIZONTAL FLUE
(For concentric vertical flue, see 4.5.2).
(For twin flue applications, see 4.5.3).
The appliance flue outlet elbow can be rotated
through 360°on its vertical axis. In addition the
fluemaybeextendedfromtheoutletelbowinthe
horizontalplane (see 2.8). A reduction must also
bemadetothemaximumlength(seetablebelow)
when additional bends are used.
Using the template provided (see fig. 6), mark
and drill a 125mm hole for the passage of the
flue pipe.The hole should have a 1°rise from the
boiler to outside.
The fixing holes for the wall-mounting bracket
should now be drilled and plugged, an
appropriate type and quantity of fixing should be
used to ensure that the bracket is mounted
securely.Once the bracket has been secured to
the wall, mount the appliance onto the bracket.
FITTINGTHE HORIZONTAL FLUE KIT
Take the large black gasket - supplied with the
flueterminal kit - and stretchitoverthe appliance
flueoutlet(fig.7).Usingatwistingmotion,connect
the boiler top adaptor - supplied with the flue
terminal kit - to the appliance flue outlet ensuring
themalespigotof the adaptor is pushed fully into
theflue outlet spigotofthe boiler(fig.7). Carefully
measure the distance from the centre of the
appliance flue outlet to the edge of the finished
outside wall (dimension X). Add 45mm to
dimension X to give you Dimension Y (see fig
7A).Measure dimensionY from the terminal end
oftheconcentric flue pipe and cut off the excess.
Pass the concentric flue pipe through the
previously drilled hole. Fit the flue bend to the
boiler top adaptor and insert the concentric flue
pipe into the flue bend ensuring the correct seal
is made.
