Flue gas routing
Before fitting the gas boiler and the flue system, check with the local
planning authority and flue gas inspector whether there are any
restrictions.
The surface temperature at the combustion air pipe is below 85 °C for
concentric pipes. No minimum clearances to flammable building
materials are therefore required. Local regulations may differ from this
information and may stipulate minimum clearances to flammable
building materials.
4.1
Approved flue accessories
The flue accessories form part of the CE approval for the appliance. For
this reason, only the provided original flue accessories must be installed.
• Flue accessories, concentric pipe Ø 60/100 mm

Installation instructions
Fan stage :1 (Reference to service function 2.b.d ( page 21).
CAUTION: Low efficiency and functional problems if an
incorrect fan stage is used!
▶ Before fitting the flue kits:
Apply a thin coating of solvent-free grease (e.g. Vaseline) to the joint
seals.
▶ When fitting the balanced flue, always push the pipe fully home into
the sockets.

Installation
DANGER: Risk of explosion!
▶ Turn off gas valve before working on gas-carrying
components.
▶ Check for leaks before working on gas-carrying
components.
Installation, power connection, connection on the gas
and flue gas side and commissioning must only be
carried out by a contractor approved for such work by
the local gas or power supply authority.
Gaz 6000 W
Not suitable for pool or spa pool application.

Important notes
▶ Before installing the appliance, consult your gas supply utility and
your local flue gas inspector [where appropriate].
Fill and top-up water for the heating system
Unsuitable fill and top-up water in the heating system can result in the
heat exchanger scaling up and failing prematurely.
Hardness range
soft ( 8.4 °dH)
medium (8.4 - 14 °dH)
hard (14 °dH)
Table 5
For straightforward water treatment:
▶ Use the system approved by us.
Open vented heating systems
▶ Open vented heating systems must be converted to sealed systems.
Gravity fed heating systems
▶ Connect the appliance to the existing pipework via a low loss header
with a dirt separator.
Galvanised radiators and pipes
To prevent gas formation:
▶ Do not use galvanised radiators or pipes.
If a room thermostat is used
▶ Do not fit a thermostatic radiator valve to the radiator in the primary
room.
Anti-freeze
The following anti-freeze fluids are permitted:
Designation
Varidos FSK
Alphi - 11
Glythermin NF
Antifrogen N
Table 6
Corrosion inhibitor
The following corrosion inhibitors are permissible:
Designation
Fernox
Sentinel
Table 7
Sealants
In our experience, adding sealants to the heating water may result in
problems (deposits in the heating block). We therefore advise against
using them.
Water circulation noises
To prevent water circulation noises:
▶ Fit an overflow valve or, with 2-pipe heating systems, a 3-way valve to
the radiator furthest from the boiler.
