Product overview

The GB402 is a floor standing condensing boiler with an aluminium heat
exchanger.
2.3.1 Product information
The main components of the Logano plus GB402 are:
• Control unit (not included in scope of delivery)
• Boiler block
• Appliance frame and casing
• Gas burner
The control unit monitors and controls all electrical components of the
floor standing boiler.
The boiler block transfers the heat generated by the burner to the
heating water. The thermal insulation reduces the radiation and standby
losses.
The control unit enables the basic operation of the heating system. It
provides the following functions, among others, for that purpose:
• Turning the heating system on/off
• Setting the DHW temperature and maximum boiler temperature in
heating mode
• Status display
The floor standing boiler can be operated with various Logamatic control
units, e.g. Logamatic 5313or 8313).
Operation of the floor standing boiler is only permitted with the control
unit also mounted on the boiler.
Many additional functions that enhance control and operating
convenience as well as providing information on the heating system
settings are described in the relevant technical documentation of the
installed control unit.
