Appliance characteristics

The Vaillant ecoTEC plus boilers are compact, wall hung 
condensing open vented boilers, designed to provide 
central heating from a fully pumped open vented or 
sealed water system and hot water where a separate in-
direct hot water cylinder is incorporated to the system. 
The central heating water temperature can be adjusted 
on the boiler. The domestic hot water temperature can 
also be adjusted on the boiler if the applicable optional 
accessories are fitted. Once the controls are set the 
boiler operates automatically. A frost protection 
programme is also included.

for the correct and economical use of your boiler. These 
instructions are applicable to the following ecoTEC plus 
boilers, available in Natural Gas.
