Page: 15 / 28

According to the Gas Safety Regulations of Hong Kong, any
gas installation works including the installation of appliances
and connection tubing, must be undertaken by registered
gas installers who are registered for that appropriate classes
and be employed by registered gas contractors.
The indoor gas hose behind the gas meter and the air inlet at
the bottom of the gas hob should be connected with a metal
bellows and a rubber hose approved by EMSD whose length
should not exceed 1.5m.
We recommend you to use the metal bellows to attach
the connecting hose. Especially, if the other appliances
are installed under the hob such as a disinfecting cabinet,
backing oven and microwave oven etc, a gas rubber hose
must not be used for the gas connection.
Using a gas rubber hose for the gas connection
-The multi-directional air inlet used for connecting the hose is
provided in the packing case of gas hob.
-The two ends of the gas hose are connected to the gas hob
and the indoor gas valve (the inside diameter of the gas hose
is 9.4mm).
-When connecting the gas hose, you must insert the gas
hose until it reaches the red line on the multi-directional air
inlet, and secure it firmly in position with a hose clip.
-After the connection is completed, please make sure that
the gas hose is not flattened, twisted or bent by any other
objects. Then smear soap suds all over the hose connection
part; and check each part of the connection hose carefully to
see if there is any leakage.
-We recommend that you perform an airtight test for the gas
hob periodically while it is in use, or else replace the gas
hose annually.
-Do not leave the gas hose in a high temperature area or put
it contact with any high temperature section of the gas hob.
