This appliance is suitable for installation with Natural Gas or
ULPG (propane/butane). Refer to page 12 for the relevant
burner pressure and appropriate injector sizes. When the
appliance is to be connected to Natural Gas then the pressure
regulator supplied must be fitted to the gas inlet. A test point (for
checking the gas pressure) is supplied either with the regulator
or as a separate fitting in the case of ULPG (propane/butane)
appliances.
Connection of the appliance to the gas supply must be in
accordance with the requirements of AS5601. A ½" BSP
connector at the inlet is recommended and the gas supply line
to the appliance must be of adequate length to allow sufficient
withdrawal of appliance for service or disconnection and be:
1. annealed copper pipe or;
2. flexible hose according to AS/NZ1869 & be at least Class "B", 10 mm diameter.
The appliance must be installed with provision to allow the gas to be turned off and
disconnected for servicing and removal of the appliance as required from the gas
supply. Before the appliance is operated make certain all relevant parts are placed in
the correct position. When the installation is completed the installation connections of
appliance will require to be leak tested, the burner operating pressure and flame
checked and adjusted. Warranty service calls do not cover these adjustments! To check
the operating pressure of the appliance it is recommended at least 2 large size burners
are used. Ensure appliance is secured to wall when installation is completed. N.G. The
regulator supplied must be fitted to the ½ BSP thread at the rear of the appliance. An
approved manual shut-off valve must be installed. The N.G. regulator must be checked
and adjusted to 1.0kPa after installation.
U.L.P.G. Can be connected to the inlet fitting directly. The
pressure must be checked to ensure it is operating at
2.75kPa. A separate test point fitting must be installed
between the piping & the appliance for the pressure to be
checked to ensure it is operating at 2.75kPa.
Installation with the flexible hose must be carried out so that the length of the piping
does not exceed 2 metres fully extended; make sure that the hoses do not come into
contact with moving parts and that they are not crushed in any way.
6.1 Connection to liquid gas
Use a pressure regulator and make the connection on the gas cylinder following the
guidelines established by the regulations in force. Make sure that the feed pressure
complies with the values indicated in the table at point "9.2 Burner and nozzle
characteristics table".
6.2 Room ventilation
Caution – This hob may only be installed and operated in rooms permanently
ventilated in accordance with current regulations. For proper operation of a gas
appliance it is essential for the air necessary for combustion of the gas to be able to
flow naturally into the room. Air must flow directly into the room through openings in its
outside walls. This (these) opening (s) must have a free passage cross-section of at
least 100 cm2, or 200 cm2 for appliances not equipped with gas safety device. These
openings must be constructed so that they cannot be obstructed indoors or outdoors,
and should preferably be close to the floor on the side opposite to the combustion gas
discharge point. If it is not possible to make the openings in the room where the
cooker is installed, the necessary air may be taken from an adjoining room, proveded
it is not a bedroom or a room with fire risk.
6.3 Combustion gas discharge
Combustion gases may be discharged by means of hoods connected to a flue with
reliable natural draught, or a fan extraction system. An effective extraction system
requires careful design by an authorised specialist, and must comply with the
regulation distances and positions. After installation, the engineer must issue a
certificate of compliance.
