Electric Connection; Exhaust System - Bertos GAS 700 Series Manual

and in conformity with regulations. After completing
the connection, check for leaks by using a special leak-
detector spray.

ELECTRIC CONNECTION

Before connecting the appliance to the network, check the
following:
- Network voltage corresponds to the data written the
plate
- Grounding is efficient
- The connection cable is suitable to the power absorbed
by the appliance.
The omnipolar switch must be close to the appliance, be
approved and have a section suitable to the appliance.
(See TECHNICAL DATA table).
The cable must have features similar to the H07 RN-f type.
To reach the power supply terminal board, carry out the
following:
- Cut off the power by turning off the switch
appliance.
- Remove the front panel by unscrewing the fixing
screws.
- Insert the cable thought the cable stopper.
Connect the two wires to the two corresponding
terminals of the terminal board.
The ground wire must be longer than the
other wires so that it will be the last to be disconnected in
the event that the cable is pulled strongly or that the cable
stopper breaks. Tighten the cable stopper.
The YELLOW-GREEN cable must never be broken.
Equipotential
The appliance must be connected to an equipotential
system. The terminal is positioned close to the cable input.
It is marked by a label:
CONNECTION TO THE WATER SUPPLY NETWORK
Connect the water input pipe to the supply network by
MOD. N°:
means of a mechanical filter and a cutoff cock.
V kW: Hz: 50/60 IPX4
Before connecting the filter, let a certain amount of water
flowing out to clean the pipe from iron scale, if any.
ATTENTION: the maximum resistance pressure of the
cock is 700 kpascal

EXHAUST SYSTEM

The appliances must be positioned in suitable areas for
the discharge of the combustible products in respect to
how much is prescribed by the installation's norms. Our
the
appliances are classified as type "A" gas units (see the
"TECHNICAL DATA" table).
They are not designed to be connected to an evacuation
duct for the discharge of combustible products.
These appliances must discharge the combustible
products into appropriate hoods, or similar devices,
connected to a flue of proven efficiency, or they may be
connected directly to an outdoor vent.
If such an arrangement is not possible, the unit may be
connected to an air exhaust system that leads directly
outdoors, having a capacity no lower than required;
see the "TECHNICAL DATA" table, plus the air exchange
necessary, in order to make operators comfortable.
