gas hob has a vertical connect
ion terminated with an internal R ½"
thread (ISO 7-R1/2). It is recommended to connect the hob to the gas distribution system by
means of a flexible hose with a safety certificate.
The system used for supplying the hob from the gas distribution system should be
equipped with a cut-off valve.
The gas hob uses a mesh gas filter, which is responsible for capturing and removing
mechanical
impurities.
It
assures
appropriate
flow
in
the
system
and efficient operation. No maintenance or cleaning is required.
If the hob is supplied with liquefied gas from a gas cylinder, connect it using a
ø10/R1/2"
connector screwed onto the gas inlet. On the cylinder valve, install a regulator for
liquefied gases. Connect the regulator with the hob using a flexible hose suitable for
liquefied gases
(with a maximum length up to 3 m)
with bands attached at both ends.
The regulator and flexible hose must have a safety certificate.
It is the user's responsibility to replace fittings
with a limited period of use.
The gas connection should be routed in such a way that there are no bends
with a radius smaller than 150 mm and that it does not come into contact with heated
elements of the hob's housing and other devices (e.g. oven).
The flexible hose that supplies the hob should be mounted in such a way that it does
not touch the moving parts of the housing section (e.g. drawer) and does not pass through a
space with insufficient dimensions.
For reasons of user safety, installation of the hob must be performed by a gas
appliance installer!
