Caution
Installation of the appliance must be done by a qualified engineer
in accordance with prevailing local and national regulations.
Caution
When connecting heat generators to under-floor heating systems
employing plastic pipes which are not impervious to oxygen in
accordance to DIN 4726, heat exchangers must be used for
separation purposes.
Important
Prevention of damage in hot water heating systems caused by
corrosion on the water side or scaling.
Caution
Keep the inflow area clear.
Never block or close off ventilation apertures. The inflow area for
combustion air must be kept clear.
Warning
Risk of damage!
The condensing boiler may only be installed in rooms with clean
combustion air. Foreign matter such as pollen must never filter
through the inlet apertures to reach the inside of the appliance.
The boiler must not be started up if there is heavy dust
development e.g. during construction work. There could be
damage to the boiler.
For ventilation-based operation of the EC five, an adequately sized
opening for combustion air must be present in the place of installation. The
operator must be informed that this opening must never be closed or
blocked and that the connecting piece for combustion air on the upper side
of the EC five must be kept free at all times.

Introduction

This section explains the conditions for heating water when Potterton
condensing boilers are used.
Important
Please note that the boiler EC five has an aluminium silicon heat
exchanger.
5.4.2

Protecting the heat generator

Faults in the heating circuit caused by corrosion or limescale deposits
reduce the efficiency and functionality of the heat generator.
The quality of the fill water must meet specific requirements. You should
therefore take preventive measures in certain cases.
