Converting The Cooktop From Nat. Gas To Universal Lpg; Changing The Nozzles Of The Burners On The Cooktop; Adjustment Of The Taps - Bosch PBH615B90A User Instructions

Gas
During the planning stage, consider the position of supply
connections.
The cooktop must be connected to the gas supply with
upstream connection of an isolation valve in accordance with
the respectively valid regulations. We recommend that the
isolation valve be fitted prior to the cooktop to enable isolation
of cooktop from gas supply. The valve must be easily
accessible at all times.
To find out the factory set gas type, see bottom of cooktop next
to gas connection.
Remove plastic cap from gas supply line prior to installation.
Fit regulator (N.G.) or a test point (Universal LPG) directly to the
R 1/2'' connection.
Direction of gas flow is indicated on the rear of the regulator.
For position of the inlet connection refer Preparing to install:
Use pipe compound or thread sealant, properly theaded pipes
and careful assembly procedure so that there is no cross
threading, etc., which might cause damage or leakage.
Make sure that all connections peformed are free of leakage.
The manufacturer does not accept any liability for leakage on
connections performed by the installer or if the L-tube is moved
or twisted.
There are two ways to carry out the connection to the main gas
line:
The hotplate can be connected with rigid pipe as specified in
■
AS/NZS 5601.1
Flexible Hose: If installing with a hose assembly, it must
■
comply with AS/NZS 1869, 10 mm ID, class B or D, no more
than 1.2 m long and installed in accordance with AS/NZS
5601.1.
Ensure that the hose does not contact the hot surfaces of the
hotplate, oven, dishwasher or any other appliance that may
be installed underneath or next to the hotplate. The hose
should not be subjected to abrasion, kinking or permanent
deformation and should be able to be inspected along its
entire length with the cooktop in the installed position. Unions
compatible with the hose fittings must be used and all
connections tested for gas leaks.
The supply connection point shall be accessible with the
appliance installed.
WARNING: Ensure that the hose assembly is restrained from
accidental contact with the flue outlet of an underbench oven.
Before Leaving- Check all connections for gas leaks with soap
and water. DO NOT use a naked flame for detecting leaks.
Ignite all burners both individually and concurrently to ensure
correct operation of gas valves, burners and ignition. Turn gas
taps to low flame position and observe stability of the flame for
each burner individually and all together. Adhere the duplicate
data plate to an accessible location near the hotplate. When
satisfied with the hotplate, please instruct the user on the
correct method of operation. In case the appliance fails to
operate correctly after all checks have been carried out, refer to
the authorised service provider in your area.
It should be expressly noted that we cannot accept any liability
for direct or indirect damage caused by wrong connection,
leakage or improper installation. When being repaired, the
appliance must always be disconnected from the mains supply;
if required, notify our customer service.
