1.1 Introduction
Dear Customer,
BlueHelix ALPHA C is a high-efficiency, low emissions premix condensing heat generator with
heat exchanger in s/steel and incorporated DHW production, equipped with a microprocessor
control system.
It can use Natural Gas (G20), Liquefied Gas (G30-G31), Propane Air (G230) and, thanks to the
"Hydrogen plug-in" system, it self adjusts to also work with mixtures of natural gas and hydro-
gen (Natural Gas/Hydrogen mixtures 80%/20%), that will soon arrive in Europe to fight global
warming.
The sealed chamber unit is suitable for indoor installation or outdoors in a partially protected
place (according to EN 15502) with temperatures to -5°C.
