Gas Commissioning
WARNING
240 VOLTS, RISK OF ELECTRICAL SHOCK!
When performing the commissioning, the appliance electrical power will need to be connected.
Wiring inside this appliance may be at 240V potential, exercise CAUTION as there is potential for
electric shock from the exposed wiring and circuitry. DO NOT leave the appliance unattended
when power is connected and the panels are removed.
Installation and commissioning must be carried out by an authorised person.
DO NOT test for gas escapes with an open ame.
NOTE
GAS PRESSURES
Refer to the appliance data plate located inside the appliance on a swing tag for correct gas
pressure settings.
To check and set burner pressures:
1. With the burner connected and pushed to the
back of the engine, using a suitable screw
driver loosen the captive Appliance Test Point
Pressure (ATPP) screw A and t manometer
(an electronic manometer is recommended).
Refer images for ATPP location.
2. Remove the brass plug B from the regulator
adjusting screw.
3. Connect and turn ‘ON’ the mains supply to the
appliance. The spark ignition will start within a
few seconds and the burner will ignite. If the
burner fails to ignite within about 5 seconds, the
spark will stop and the gas will cease to ow.
It may take several attempts to get the burner
to ignite especially with a new gas installation.
Restart the appliance by turning the mains
power switch off, waiting a couple of seconds,
then switching back on.
4. Adjust the burner pressure with the regulator
adjusting screw C. Checking the pressures
against that of the data plate. Turning clockwise
increases the outlet pressure whilst turning
anticlockwise decreases the outlet pressure.
5. Once adjusted turn the mains supply to the
appliance ‘OFF’, replace the brass plug B and
remove the manometer and re-tighten the ATPP
screw A. Check all connections and test points
for leaks using soapy water solutions.
WARNING
To ensure the correct operation of the valve it is necessary that the brass plug B is returned to
its original location.
6. Turn the appliance ‘ON’ and ‘OFF’ a few times to conrm correct ignition and operation.
7. Check the ame pattern, see “When to call for Service” on page 7.
