TESTING AND SETTING
PAGE 5 OF 6
After installing the gas supply and making all connections check thoroughly for possible leaks. Turn all control knobs on unit to "off" position. Open the valve on the gas supply. Using a leak detection fluid (e.g. Rocol leak detection spray) check each gas connection one at a time by brushing the solution over the connection. The presence of bubbles will indicate a leak. Tighten the fitting and recheck for leaks.
Leak testing of the appliance shall be conducted according to the manufacturer's instructions.
Turn on burner valve and light each burner. Check for a clear blue flame without yellow tipping. If burners show any abnormalities, check that they are located properly and in line with the injector orifice.
The appliance and it's individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system in excess of 1/2 p.s.i. (3.5kPa).
The appliance must be isolated from the gas supply piping system by closing it's individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures at or less than 1/2 p.s.i.(3.5kPa).
Maximum inlet gas supply pressure 4" W.P. Natural Gas, 11" W.P. LP gas.
Minimum gas supply pressure for regulator testing 5" W.P. Natural Gas, 12" W.P. LP gas.
CONVERSION TO DIFFERENT GAS TYPE

Burners can be used with all types of gas, provided that the orifices appropriate for the gas delivered are installed.
You will need a 9/32" (7mm) socket (and a 13/32" (10mm) socket for the GC901M).
To change the orifices:
1.Turn off the mains supply.
2.Ensure all gas valves are turned off.
3.Remove all grates and burner heads.
4.Pull off knobs.
5.Remove the two screws securing each burner (three on the wok burner).
6.Partially lift the hob and unplug the electrode on the simmer burner (CAUTION: the edge can be sharp).
7. Unscrew the orifices and replace them with the correct ones. (Size numbers are stamped on the side e.g. 70 = 0.70mm).
8. Set the brass venturi on the wok burner to a distance of 3/5” (15mm) as indicated.
9. To replace the hob, repeat steps
The label supplied with the orifices can be placed over the existing gas label to indicate the change.
High altitude orifices are available from Fisher & Paykel USA (see address).
