2.2 commissioning
2.2.1 Filling the water heater
1. Close the drain tap.
2. Open the cold water tap to the water
heater and open all taps where hot
water can be drained for de aeration.
The water heater is filled as soon as
cold water flows from all taps.
3. Close all hot water taps.
2.2.2 Putting into operation
1. Check to see if the heater is filled
with water by running a little to waste
from a hot water tap connected to the
heater.
2. Check wether the ON/OFF switch is
in OFF-position.
3. Ensure gas supply is fully purged of
air and turn on gas cock.
4. Ensure that power has been correctly
supplied to the unit. Use a voltage
tester to check that the live is to “L”
and neutral to “N”. (Flame detection is
phase sensitive).
5. When first starting, the controller can
be in the lock out condition: depress
the reset button to free the control.
(After manual reset, an extended
prepurge/waiting time will occur).
6. Switch the ON/OFF switch into ON
position. If the pilot fails to ignite
within 25 seconds the controls will go
to lock out and the reset button will
need to be reset (wait 15 seconds
before attempting reset). It may be
necessary to repeat the lighting
sequence a number of times on the
initial light up if all the air has not
been purged from the gas supply.
7. The main burner pressure has been
factory set but should be checked
once normal operation is established
(see ‘Ratings’ for settings).
8. Set the temperature regulator
to the required setting (see
‘Descalcification’).
Note: If during normal use the reset
button is pressed the gas valves
will close and the automatic ignition
controller will start a new sequence after
releasing the reset button.
2.2.3 shut down
Note:The water heater should only be
turned off when hot water will not be
required for an extended period (e.g.
holidays); otherwise it should be left on.
To shut down put the ON/OFF switch into
OFF position.
