Note
Two types of flue gas installation are available
for ecoTEC boilers:
- standard concentric flue gas installations
(outer diameter 100 mm)
- a concentric system with a larger diameter
(outer diameter 125mm) which can be used to
achieve longer air/flue gas pipes.
Note
The air/flue duct operates at very low tempera-
tures therefore no clearance is necessary be-
tween the air duct and adjacent services.
Note
Ensure while installation work is being carried
out that no debris such as swarf, filings or frag-
ments of mortar are allowed to remain in the
air/flue duct.
2.1.1
Intended
use
Valliant flue pipes for ecoTEC are state-of-the-art
appliances which are designed in accordance with
approved safety regulations. Nevertheless, there is still
a risk of death or serious injury to the user or others or
of damage to the device and other property in the event
of improper use or use for which it is not intended.
The Vaillant flue pipes for ecoTEC may only be used
with the unit types named in this installation manual.
Any other use or extended use is considered to be im-
proper. The manufacturer or supplier is not liable for
any resulting damage. The user alone bears the risk. In-
tended use includes the observance of the relevant
manual.
2.1.2
Preliminary remarks for room sealed appli-
ances
This appliance should only be installed in conjunction
with either a Vaillant flue system or an alternative ap-
proved system (details of flue approval categories can
be found in the technical section of the installation man-
ual).
Install the flue system as detailed in the separate flue
installation instructions supplied with this boiler.
