Gas Connection (If Fitted) - Astoria 1GR Use And Maintenance Manual

The electrical system must be equipped with a
protection device (8) that ensures an omnipolar
disconnection from the mains with a contact
opening distance in overvoltage category III conditions
and which guarantees a suitable residual-current device,
equal to 30 mA, in compliance with current laws and
safety regulations.
Always connect the motor pump cable before
the machine power supply cable, by following
the diagram provided. Failure to comply with
the instructions given above may cause serious damage
to the machine and/or motor pump and will invalidate
any guarantee.
We recommend that you promptly report any problems
encountered during the appliance's installation to the
Manufacturer.

doors, always provide air vents so that any gas leaks can
escape.
Do not under any circumstances attempt to light the gas
without first installing the proper injector.
Do not start up the gas burners when the heating unit is
empty.
