Danger!
Vaillant appliances are certified only for use
with ge-nuine Vaillant flue pipes. Only use gen-
uine Vaillant flue pipes. Malfunctions can occur
if you use other accessories. These may result
in damage and injury. You will find a list of gen-
uine flue pipes in the Vaillant installation man-
ual for flue pipes. The CE mark is valid only if
the appliance is operated with Vaillant flue
pipes.
4.2.1 Other flue options
Flue instructions for other flue systems such as vertical
RSF flues, flues run to the side of the boiler and the use
of additional bends etc. are detailed in the flue installa-
tion instructions.
4.3 Fitting the boiler hanging bracket
Reposition the wall template over the flue hole ensuring
the template is vertical and mark the position of the fix-
ing holes for the hanging bracket, see fig 4.3. Mark and
drill the fixing holes and secure the hanging bracket. Fix
the hanging bracket to the wall using the screws sup-
plied. Ensure the uppermost set of screw positions are
used (it may be necessary to use additional or alterna-
tive fixings to ensure adequate support).

leakage only with a maximum pressure of 150
mbar! Higher testing pressures can damage the
gas fitting.

When making final connection to the boiler, if
using soldered fittings, extra care should be
taken to avoid damage to isolation valves
through heat transfer. Before connection check
the supply of local gas.
