Checking Gas Pressure; Connecting To A Different Type Of Gas - Bartscher GG740 Manual De Instrucciones

The appliance must be supplied with one of
the types of gas whose properties and pres-
sure are set out in the table below:
Connect the appliance to a special gas pipe
with an internal diameter of at least 16 mm for
G1/2" connections and a diameter of at least
20 mm for G3/4" connections. Make sure that
the fl exible metal pipe that is fi tted to the gas
coupling does not touch overheated parts of the grid and is not twisted. Place a rapid stopcock between the mains
gas supply and each single appliance in a position that enables it to be easily opened and closed (the internal
diameter must not be less than that of the connecting pipe). After connecting the pipe, make sure that the joints
and couplings have no leaks. Use soapy water or a purpose-designed foam product to detect leaks.
NEVER USE NAKED LIGHTS!

Gas supply pressure must be measured at the pressure point
(Ref. B) after removing the sealing screw (Ref. A). Use a fl exible
pipe, connect a gauge e.g. a liquid gauge that is accurate to 0.1
mbar) to the pressure point (and measure the intake pressure
whilst the appliance is operating. If the pressure reading does
not fall within the upper and lower limits indicated on the table,
the appliance cannot be installed.
Switch off the appliance, disconnect the gauge and close the seal
screw without forgetting to insert the washer (Ref. C) and contact
the gas company to test main gas supply pressure.

- Open door or doors.
- Remove the grease drip trays.
- Loosen the screws that hold the front control panel in place
and disconnect the electric cables of the piezoelectric igni-
tion.
- Loosen the main injectors (Ref. B) and replace them with those
corresponding to the gas used. The diameter is stamped in
hundredths of a millimetre on them and can also be checked
on the Specifi cations Table.
