Commissioning Gas Type Conversion
Tools required:
• A manometer capable of reading from 0 to at least
3.0kPa.
1. Remove the Test Point (TP) from the appliance Gas
Regulator and connect a manometer capable of reading
from 0 to at least 3.0kPa.
2. Turn on the gas supply to the appliance and test for
leaks.
Gas Hob Commissioning
1. Turn on a Gas Hob burner to high and hold the gas
valve control knob in. At the same time use the inbuilt
igniter (240v powered models) or a gas match applied
to that burner to provide an ignition source.
2. Once the burner is lit and after 5s release the valve knob
and observe for the following:
a. Flames have traveled to all burner ports promptly.
b. Burner stays alight once gas valve knob is released.
c. Burner flames are almost entirely blue. Some light
yellow within the flame may be present but there
should be no yellow at the tip at the outer end of the
flame.
d. The TP pressure as indicated by the manometer
should be between 3.12kPa and 2.08kPa.
(2.60kPa +/- 20%)
e. See "Fault Finding" if any of these requirements are
not met.
3. Rapidly move the gas valve of the lit burner from high
to low and back again a few times. The burner should
stay alight. If the burner does not stay alight, adjust the
turndown for that burner at the gas valve slightly counter-
clockwise to increase the gas rate at minimum turndown.
Refer to Gas Hob Conversion instructions.
4. Shut off the burner and repeat for all other Gas Hob
Burners.
5. Light all Gas Hob Burners and repeat step 2.
