Electrical Connections - Worcester GB162-50 Installation And Servicing Instructions

Installation
Example of a flue design calculation for concentric flue system
100/150 using length method
Boiler: GB162-80
Flue system: concentric 100/150
Maximum length: 18 m.
Here we have:
• 4 meter pipe (2 x 2 m)4.0 m
• 2 x 90° bends (2 x 2.1 m)4.2 m
The total length of this flue system =8.2 m
Sum of length (8.2 m) < maximum length (18 m)  robust flue design!
Pipe=2m
90° bend
Length=21m Pipe=2m
Maximum length
allowed after the
boiler (GB162-80)

Electrical connections

When connecting the electrical components, observe the wiring
diagram, the installation and servicing instructions of the relevant
product.
WARNING: Damage to the installation due to short
circuits.
To prevent electrical components from short-circuiting,
only use:
– original cables and wiring supplied by the
manufacturer.
– single core cable.
▶ Use cable of at least 0.75 mm².
▶ If the mains lead has to be replaced, you may only use
an original manufacturer-supplied mains lead.
DANGER: Danger of fatal accident due to electric
current when the boiler is open.
▶ Before opening the boiler: Isolate the mains supply.
▶ Secure the heating system so that it cannot be
switched on again unexpectedly, pulling the mains
plug from the wall socket.
The 230V converter can only be used for the
GB162-50/65 appliance.
