ecoTEC plus boilers

The ecoTEC plus boilers are designed to provide central
heating from a fully pumped open-vented or sealed
water system. The central heating water temperature
can be adjusted on the boiler. The domestic hot water
can only be adjusted on the boiler if it is installed with a
Vaillant uniSTOR unvented cylinder and relevant con-
trols. Once the controls are set the boiler operates auto-
matically.
A frost protection programme is also included.
Please read these instructions and follow them carefully
for the correct and economical use of your boiler. These
instructions are applicable to the following ecoTEC plus
boilers, available in Natural Gas. All ecoTEC plus boilers
can be converted to LPG.

Intended use

The boiler has been designed for use with a open-vented
central heating system, and comes fully tested and
assembled. The boiler is easily mounted on any internal
wall and can be installed with either a horizontal or ver-
tical RSF (room sealed fan assisted) flue. The boiler uses
a standard flue system (100 mm or 125 mm outside di-
ameter). Flue extensions and additional bends and el-
bows are available for the flue system to increase the
flexibility. If desired, an inhibitor may be used in the sys-
tem. Guidance on the use of inhibitors is contained in
these instructions. The boiler has a built in diagnostic
system which indicates the operational status of the
boiler. This feature provides key information to aid com-
missioning and fault finding. The data badge is fitted to
