qualified persons. All connections must be checked
for leaks before re-commissioning the appliance.
•
For all relevant gas specifications refer to the table at

Open Burners ('F' - Flame Failure Option)
1. Turn off the gas supply at the main supply.
2. Remove the trivets from the top of the appliance, taking
note that the trivets are manufactured with a lip on one
edge, the lip must always be fitted to the outer edge (front
and back) of the range. (See Fig 18)
3. Remove the burner cap and burner bowl (these are a loose
fit to the manifold) (See Fig 13) from the top of the gas
manifold, taking care not to damage the thermocouple fitted
through the manifold splash guard.
4. Remove all the trivet supports from the top of the appliance.
Note the orientation of the trivet support when
removing. The front end side rail profiles are
different from the rear end side rail profiles. (See Fig
14).
5. Remove the splash guard covering the burner manifolds by
unscrewing the two allan headed screws. (Refer to Fig 15).
Carefully remove the splash guard taking care not to
damage the thermocouples.
6. Unscrew and remove the injectors (13mm or ½ A/F) from
the gas cocks. (See Fig 16)
7. Determine the correct injector sizes for the corresponding
gas from the rating plate affixed to the bottom right hand
corner of the bottom sill.
8. Replace with correct size injectors. Refer to ‘Gas
Specifications Table’ for injector sizes.
9. Refit the splash guards over the gas cocks taking care not to
damage the thermocouples and secure in position with the 2
allan headed screws. (See Fig 15).
10. Refit the burner bowls and caps onto the manifolds
protruding through the splash guards, taking care not to
damage the thermocouple. Take note that the burner bowl
(cast item) has 2 locating holes drilled into the base flange
(See Fig 17), these are to locate the burner bowl onto the
allen headed screw that secures the splash guard to the gas
manifold. (See Fig 15).
11. Turn on the gas supply at the mains, re-light the burners
and check the flame size on the simmer ‘LOW’ position.
NOTE: The right hand gas control valve supplies the rear
burner and the left hand gas control valve supplies the
front burner.
