WARNING
:
The outer case of this appliance is not
merely a cosmetic device. It is a
functioning component in the air supply
to the burner and MUST BE replaced
with great care NOW, before any
attempt is made to light the burners.
TO ALLOW THE MAIN BURNER TO
IGNITE WITHOUT THE CASE IN
POSITION IS A HAZARD.
1. Refit the outer case ensuring it is
correctly seated then secure (3 screws).
Ensure that the temperature selector
control rod (if fitted) is set at its maximum
setting.
2. Ensure that the gas and water supplies
are turned ON.
3. Ensure that all hot water outlets are
closed.
4. Remove the screw and sealing ring from
the burner pressure test point and attach
a pressure gauge.
5. Fully depress and hold the ON button
and repeatedly press and release the
IGN button until the pilot is lit. The pilot
flame can be observed through the pilot
viewing window.
6. Hold the ON button in for a further
10 seconds after the pilot is lit, then
release. If the pilot goes out, repeat the
lighting operation keeping the ON button
depressed a little longer.
7. Test for gas soundness using a suitable
leak detection fluid on all external gas
joints.
8. Open a hot water outlet and the burner
will ignite. Allow the water to run for a few
minutes then check the burner pressure -
it should be 12.5 mbar (5 in w.g.), if the
pressure is not correct see the FAULT
FINDING section.
