1. Introduction
1.1. General Warnings / Warranty Issues
Please refer and use the information in the content of this manual textbook. Obey the
instructions, warnings and advices. The warnings and instructions are the matter of your and
your device’s safety. The sections of this manual textbook are mostly in the order of the start of
comissioning with the unpacking of the device towards decomissioning and disassembling.
The neutral keeping position of your device unless it is hanged on a wall or a hanging structure is
horizontal with front side (the side including the control panel, on which the ALDENS LOGO and the
word “ALDENS” is also written) directed upwards. Especially please refer to this information in case
of heat exchanger assembling or disassembling.
As factory setting, ALDENS boilers are set to operate with natural gas fuel. Whether if LPG will be
used as fuel for a single or a cascade system, all the boilers should be adapted to operate with LPG
fuel. For establishing this adaptation please refer to Alarko Carrier authorized services.
