1.3 General
notes
The ecoTEC plus 937 is designed for use in a closed
central heating system and is comprehensively tested in
the factory. The ecoTEC plus 937 is supplied fitted with a
circulation pump, an expansion vessel, a diverter valve
and a shift load 15 l power store. The shift load storage
tank and combination boiler can be easily mounted on
an internal wall and installed with a vertical or horizontal
RSF (room sealed fan assisted flue).
The combination boilers operate with a standard flue
gas system (outside diameter 100 or 125 mm). To
increase the flexibility of the system, extensions and
additional right-angle and leg extensions are available. If
required, an inhibitor can be used in the system.
Instructions for the use of these inhibitors can be found
in their instructions.
All combination boilers are equipped with an internal
diagnostic system which provides information
concerning the operating status of the combination
boiler. This diagnostic system provides important
information to support commissioning and
troubleshooting.
1.4 Intended
use
The ecoTEC plus 937 is a state-of-the-art appliance
which has been constructed in accordance with
recognised safety regulations. Nevertheless, there is still
a risk of injury or death to the user or others or of
damage to the equipment and other property in the
event of improper use or use for which they are not
intended.
The appliance is designed to generate heat for closed
hot water central heating systems and for instantaneous
hot water supply. Any other use or extended use is
considered to be improper.
The manufacturer or supplier is not liable for any
resulting damage. The user alone bears the risk.
Intended use includes the observance of the operating
and installation manual and the adherence to the
inspection and maintenance conditions.
