d Danger!
Vaillant appliances are certified only for use with ge-
nuine Vaillant flue pipes. Only use genuine Vaillant
flue pipes. Malfunctions can occur if you use other
accessories. These may result in damage and injury.
You will find a list of genuine flue pipes in the Vaillant
installation manual 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.

Fitting the boiler hanging bracket

Reposition the wall template over the flue hole ensuring the
template is vertical and mark the position of the fixing 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 supplied. Ensure the uppermost
set of screw positions are used (it may be necessary to use
additional or alternative fixings to ensure adequate support).

If the boiler is to be fitted in a timber framed
building ensure that the bracket is secured to
a substantial part of the timber frame capable
of taking the weight of the boiler.

d Danger!
The gas connection may only be made by a
competent person. The legal directives and the
local regulations for gas supply companies
must be observed.
Caution!
a
Ensure a stress-relief assembly of the gas
pipes to avoid leakages!
a Caution!
The gas regulating block may be tested for leakage
only with a maximum pressure of 150 mbar! High-
er testing pressures can damage the gas fitting.
Caution!
a
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.
h Note!
Ensure the gas supply pipe work is adequately
sized so that a 20 mbar gas pressure is available
at the boiler inlet at full flow rate.
• Tighten all connections.
• Check the gas connection with leak indicator
spray for leakage.
The gas supply can be connected from below, or through the
wall at the rear of the boiler. See fig 4.5. and refer to section 3.4.
The whole of the gas installation, including the meter,
should be inspected, tested for soundness and purged
in accordance with the current issue of BS6891 and in IE
the current edition of I.S.813 "Domestic Gas Installations".
