the following wall-mounted condensing gas boilers:
The Wallcon 42/50/67 is suitable for use as a single boiler or as
part of a cascade system.
CE LABEL
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.

Wallcon 50
The boiler may only be used to heat up water for heating
systems as standard and/or domestic hot water (DHW)
systems with the connection of DHW tank.
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 maximum of 16 boilers with
can be connected together.
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.
Also, 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.
CAUTION:
Damage to the installation due to frost.
Install the heating system in a room
which is free from frost.
WARNING:
Fire hazard due to flammable materials or
liquids.
Do not store any flammable materials or
liquids in the direct vicinity of the boiler.
CAUTION:
Boiler damage due to contaminated
combustion air or contaminated air in the
boiler room.
Never use the boiler in an environment which
contains lots of dust or aggressive chemicals.
Such as spray shops,hairdresser's shops,
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.

The WALLCON is a wall-hung condensing boiler, for
CH and DHW(with DHW tank) purposes, with pre-mix
burner, made up of stainless steel heat exchanger.
The
WALLCON boilers can be combined in a cascade
configuration with other heat generators to create
modular heating plants made up of boilers connected to
the same water circuit and with electr onic controllers
communicating via bus. The heat output of each boiler
o
unit reaches 42kW (100%, 50
o
C / 30 C) for Wallcon 42
,
o o
51kW (100%, 50 C / 30 C) for Wallcon 50 and 67 kW
2.2 DESCRIPTION OF THE APPLIANCE
The individual heating units in cascading configuration
can be activated, as well as by simple rotation, in such a
way that when a certain percentage of output is reached
by the first unit, the other units start automatically, all with
the same load factor.
The main features of the
WALLCON Boilers are:
- cold burner door with premix burner
- output from 8.5 to 42 kW (models 42 M and 42 S)
- output from 8.5 to 51 kW (models 50 M and 50 S)
-
- microprocessor control with self-diagnosis, shown on
LED and the display
- frost protection function activated according to the out-
side temperature and/or the temperature of the boiler
- fitted for room thermostat in the high and low tempera-
ture zones(optional)
- outside probe to enable the climate control function
- post-circulation function for the central heating and
DHW circuits
- priority settable on the DHW, high or low temperatur e
circuit
-
- low investment costs for cascade operations ( slave
- chimney sweep function
-
-
solar system & swimming pool control functions
models can be controlled by Master models, without
using any display modules in slave units)
