Checking gas pressures
The cooker MUST be installed in compliance with:
• the Australian Standard AS5601 (particular reference to clause 5.12.1).
• local gas fitting regulations, municipal building codes and other statutory regulations.
The cookers come in three gas types: Natural gas, Universal LPG and Propane. Before
installation check that the cooker is suitable for the gas supply. To do this check the gas type on
the carton sticker or on the data plate behind the bottom of the oven door.
The following table shows the supply and operating pressures for various gas supplies.
GAS TYPE NATURAL GAS UNIVERSAL LPG
SUPPLY PRESSURE
at inlet to appliance regulator (if fitted) 1.13 (kPa) Minimum 2.75* (kPa)
OPERATING PRESSURE
at appliance test point 1.00 (kPa) 2.75 (kPa)
* If the regulator is placed upstream of the cooker inlet, as is normal for cookers operating on
LPG, then the supply pressure and operating pressure are the same.
The following table shows the injector sizes for each burner.
INJECTOR ORIFICE NATURAL GAS UNIVERSAL LPG
LOW HEAT BURNER 1.00 mm 0.55 mm
MEDIUM HEAT BURNER 1.35 mm 0.70 mm
HIGH HEAT BURNER 1.60 mm 0.90 mm
INTENSE HEAT WOK BURNER 1.75 mm 1.00 mm
OVEN - main injector 1.50 mm 0.82 mm
Checking pipe size
To work out a suitable pipe size for connection use:
• the information in this table.
GAS TYPE NATURAL GAS UNIVERSAL LPG
Hourly gas consumption for GSN625/627 51.1MJ/h 44.4MJ/h
Hourly gas consumption for DSN635 40.6MJ/h 35.4MJ/h
• information about the length of the run, number of elbows, tees and bends, the available
service pressure and the supply requirements.
NOTE: AS5601 will help you with this matter.
