1.3 General notes
The ecoTEC plus 937 is designed for use in a closed cen-
tral 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 15 l layered storage tank. The shift load storage
tank and combination boiler can be easily mounted on
an internal wall and installed with a vertical or horizon-
tal RSF (room sealed fan assisted flue).
The combination boilers operate with a standard flue
gas system (outside diameter 100 or 125 mm). To in-
crease the flexibility of the system, extensions and addi-
tional right-angle and leg extensions are available. If re-
quired, an inhibitor can be used in the system. Instruc-
tions for the use of these inhibitors can be found in
their instructions.
All combination boilers are equipped with an internal di-
agnostic system which provides information concerning
the operating status of the combination boiler. This di-
agnostic system provides important information to sup-
port 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 recog-
nised safety regulations. Nevertheless, there is still a
risk of injury or death to the user or others or of dam-
age 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 instantane-
ous hot water supply. Any other use or extended use is
considered to be improper.
The manufacturer or supplier is not liable for any result-
ing damage. The user alone bears the risk.
The unit is not intended for use by persons (including
children) with reduced physical, sensory or mental capa-
bilities, or lack of experience and/or knowledge, unless
they have been given supervision or instruction con-
cerning use of the unit by a person responsible for their
safety. Children must be watched to ensure that they do
not play with the unit.
