2.1 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

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. Instruc-

tions 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 concern-

ing the operating status of the combination boiler. This

diagnostic system provides important information to

support commissioning and troubleshooting.
