REGULATIONS AND DIRECTIVES

3 REGULATIONS AND DIRECTIVES
3.1

DESIGNATED USE

The boiler may only be used to heat up water for heating
systems and/or domestic hot water (DHW) systems.
The boiler can be installed either as a single system or as
part of a multiple system (cascade system). A cascade
system enables several boilers of this type to be
connected together, where a maximum of 8 boilers with
a total capacity of 800 kW can be connected together on
a floor surface of approx. 2 m².
Special cascade units (accessories) have been
developed to enable this boiler to be installed in a
cascade system. Every cascade unit includes an
installation frame, horizontal headers, connection pipes
for the boiler, main gas pipe and vertical low loss header.
Cascade units are available for installing the boilers
inline or back-to-back. These cascade units make
installing a cascade system easier and less labour
intensive. Please contact your dealer or the
manufacturer for further information about cascade
systems.
The construction and operating behaviour of the boiler
are in accordance with the requirements listed:
The appliance complies with the basic
requirements of the relevant European
directives.
Conformity has been substantiated by
the proper documents which - together
with the declaration of conformity - are
filed with the manufacturer.
3.2

BOILER ROOM

CAUTION:
Damage to the installation due to frost.
B Install the heating system in a room
which is free from frost.
WARNING:
Fire hazard due to flammable materials or
liquids.
B Do not store any flammable materials or
liquids in the direct vicinity of the boiler.
B Observe all statutory building regulations applying to
the place of installation.
12
CAUTION:
Boiler damage due to contaminated
combustion air or contaminated air in the
boiler room.
B Never use the boiler in an environment
which contains lots of dust or aggressive
chemicals. Such as spray shops,
hairdresser's shops, agricultural
enterprises (manure) or locations where
tricholorethylene or hydrogen halides
(e.g. contained in aerosols, certain
adhesives, solvents or detergents,
paints) and other aggressive chemicals
are used or stored.
B In such situations you must opt for a
room sealed installation.
The boiler can only be mounted to the wall or installed
in a cascade system. When installed in a room with thin
walls or a thin floor, resonating noise may occur. Install
noise reducing parts if required.
3.3 COMBUSTION AIR FLUE GAS
CONNECTION
If the boiler is operated dependent on room air, the
installation room must have the required air vents.
DO NOT obstruct these vents. The air vents must always
be free.
3.4 QUALITY OF THE HEATING SYSTEM
WATER
Thoroughly clean and flush the system before filling it.
Use only unsoftened mains tap water when filling or
topping up the system. The use of dirty water will lead to
build-ups of sludge and corrosion, which can in turn
result in malfunctioning of the boiler and damage to the
heat exchanger.
Inhibit the system with the correct dossage of an
approved product.
DO NOT treat the water with antifreeze or water
softeners.
The pH of the heating system water MUST be between 7
and 8.5. If this is not the case, please contact Worcester
Customer Service before proceeding.
