WARNING
caution
Cooktops are supplied for use with natural gas (NG). To use with
LPG, the injectors MUST be changed using the conversion kit
supplied. Refer LP Conversion on page 13 and 15).
This appliance must be installed by an authorised person and in
compliance with:
1. AS/NZS 5601.1 Gas Installations Part 1: General
Installations, and AS/NZS 5601.2 Gas Installations Part 2:
LP Gas installations in caravans and boats for non-propulsive
purposes, or the relevant installation code for gas appliances
in your country.
2. The local gas fitting regulations, municipal building codes,
electrical wiring regulations and any other relevant statutory
regulations.
3. The particular instructions as given below. Before commencing
installation, check to ensure that the appliance gas type given
on the data plate on the appliance corresponds with the type
of gas to which it is intended the appliance be connected.
4. A certificate of compliance MUST be given to the customer
after the application is successfully installed.
5. This appliance must be earthed (240V models only).
Installation procedure
1. The bench cutout should be made as per cutout dimensions in
Table 2 and Figure 4.
2. Adjacent walls, cupboards and protection for combustible
materials: Ensure that the appliance is installed in accordance
with clauses 6.2.5 and 6.10.1.1 of AS/NZS 5601.1, or
clauses 6.9.1 and 6.9.5 of AS/NZS 5601.2 with regard
to clearances to combustible surfaces and materials, and
clearances to rangehoods and exhaust fans.
To ensure clearances of 200mm from burners to vertical
combustible surfaces observe the minimum distance
requirements shown in Figure 5.
Clearances to combustible surfaces may be reduced if
combustible surfaces are protected in accordance with clause
6.10.1.2 of AS/NZS 5601.1, or clause 6.9.2 of AS/NZS
5601.2.
NOTE: For installation into a standard 600mm width
benchtop the clearance specified can not be achieved
and combustible surfaces must be protected in
accordance with the above clauses.
3.
Optional barrier:
A barrier can be installed to prevent
accidental contact with the cooktop base, where the base of
the cooktop is accessible from below (i.e. Inside a cupboard,
etc.). An impression has been incorporated into the base to
ensure a minimum clearance of 10mm is maintained between
the base and the barrier. This barrier may be made of any
rigid material.
Barrier protection is not necessary if the product is installed
above an underbench oven or similar appliance and/or if
the cupboard construction is such that the underside of the
cooktop is not accessible.
