These instructions provide the operator of the heating system with an
overview of the use and operation of the boiler.
The Logano G334X floor-standing gas boiler is generally referred to
below as a boiler.
2.1

Designated use

indirect provision of domestic hot water (e.g. in a hot water storage
tank) in residential buildings or apartment buildings. Any other purpose
is considered improper use.
2.2

Product Description

The boiler is a gas floor standing boiler employing gas combustion.
The boiler is fully functional with the factory-installed
aquastat. A Logamatic 2107 controller can be installed
in addition to the factory-installed aquastat.
The boiler consists of the following main components ( Fig. 1):
• Automatic ignition unit and aquastat
• Logamatic 2107 control (optional control)
• Boiler casing and front cover
• Boiler block with insulation
• Burners
The burner controller, the aquastat and, if installed, the Logamatic 2107
controller monitor and control all electrical and operational components
of the boiler.
The boiler casing prevents energy loss and acts as soundproofing.
The boiler block transfers the heat generated by the burner to the boiler
water. The insulation reduces energy loss.
