COMMISSIONING THE APPLIANCE
a)
Loosen the screw and connect a manometer to the burner
pressure test point on the gas valve (Fig. 35).
b)
Turn the hot water control (Fig. 30) to maximum (fully
clockwise). Turn on the electrical supply and select the Hot
Water position on the Main Switch – the Power On LED will
be illuminated.
c)
Fully open any DHW tap and the ignition sequence will
commence. The Hot Water and the Burner On LEDs will be
illuminated. If the burner fails to light, ignition lock-out occurs.
In the event of ignition Lock-out the safety Lock-out LED will be
illuminated. To re-set the appliance and initiate a further
ignition attempt it is necessary to turn the Main Switch through
to the Reset position (spring return).
d)
After ignition, allow the boiler to run for at least 10 minutes
and check that the burner pressure is as stated on the data
badge ±10%. The DHW burner pressure is factory set and
should not require adjusting. If the burner pressure is low,
check that the appliance has not started to modulate (This will
occur if the DHW flow rate is low. If modulation is suspected,
open all DHW taps to maximise flow and re-check burner
pressure) If it is necessary to adjust the DHW burner pressure
the method is described in section 9.6 Gas valve replacement.
e)
Close the DHW tap and ensure that the Burner On LED (Fig. 30)
goes off, the burner goes out, and the pump stops after an
overrun period.
f)
Ensure that the room thermostat (if fitted) is calling for heat. Turn
the Main Switch to Heating & Water and turn the heating
control knob (Fig. 30) to maximum (fully clockwise), and finally
turn the clock override switch (Fig. 30) to the I position. The
burner will light at an ignition gas rate of approx. 5 mbar. After
ignition the burner pressure drops to approx. 1.3 mbar and
over a period of time the heating load will ramp up to factory
set burner pressure.
NOTE: that the central heating burner pressure is
factory set to 6.3 mbar (app. 19.5kW or 66,000 Btu/h,
gross heat input) and should not require adjusting. If it
is necessary to adjust the CH burner pressure the
method is described in section 9.9.1 Gas valve
replacement.
g)
Set the clock to the desired times by setting the tabs.
h)
Slide the clock override switch to the 'timed' position and
check the operation of the clock and room thermostat (If fitted).
