Regulations
Where no specific instruction is given, reference should be made to the
following standards:
• AS/NZS 5601 Gas Installations,
• AS 1596 LPG storage and handling,
• AS 4552 Gas fired water heaters for hot water supply and/or central
heating,
• AS/NZS 3000 Electrical Installations,
• AS1697 Installation and maintenance of steel pipe systems for gas,
• AS 4032 Water supply - valves for the control of hot water supply
temperatures,

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)

Flue gas routing
For straightforward water treatment:
▶ Use the system approved by us.
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
4.2
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.
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:

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.

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.

The characteristic curves shown are based on the following key data:
• 1% water volume in expansion vessel or 20% of nominal volume of
expansion vessel
• Differential operating pressure of the safety valve of 0.5 bar,
according to DIN 3320
• Pre-charge pressure of expansion vessels matches static head of the
system above the heat exchanger
• Maximum operating pressure of 3 bar

▶ Pluming will occur at the terminal so terminal positions where this
could cause a nuisance should be avoided.
▶ The air supply and the flue gas exhaust must meet the applicable
general regulations. Please consult the instructions provided with the
flue terminal kits prior to installation.
▶ The boiler must be installed so that the terminal is exposed to the
external air.
▶ It is important that the position of the terminal allows the free passage
of air at all times.
▶ Minimum acceptable spacing from the openings are specified above,
for domestic situations in accordance with AS 5601.

Pump anti-seizing function
This function prevents the heating pump and the 3-way

The anti-seizing function remains active during standby
mode.
Every time the pump is switched off, a timer is started. If after 24 hours
the pump has not run again, it is switched on briefly.
Frost protection for the heating system is only ensured if the heating
circuit pump is operational and is pumping heating water through the
entire system.
▶ Leave the heating switched on.
▶ Set the maximum flow temperature to at least 40 °C (chapter 7.4).
-or- If you want to leave the appliance switched off:
▶ Add anti-freeze to the heating water ( page 9) and drain the DHW
circuit.
For further information, see the heating controller
operating instructions.
Appliance frost protection:
The appliance frost protection function switches the burner and heating
circuit pump on when the temperature in the installation room (at
temperature sensor for heating flow) falls below 5 °C. This prevents the
boiler freezing up.
▶ Activate summer mode ( chapter 7.7) or set the appliance to
standby mode ( chapter 7.3).

Important notes
12
Environment / disposal
Environmental protection is a fundamental corporate strategy of the
Bosch Group.
The quality of our products, their efficiency and environmental safety
are all of equal importance to us and all environmental protection
legislation and regulations are strictly observed.
We use the best possible technology and materials for protecting the
environment taking into account of economic considerations.
Packaging
We participate in the recycling programmes of the countries in which our
products are sold to ensure optimum recycling.
All of our packaging materials are environmentally friendly and can be
recycled.
Used appliances
Used appliances contain valuable materials that should be recycled.
The various assemblies can be easily dismantled and synthetic materials
are marked accordingly. Assemblies can therefore be sorted by
composition and passed on for recycling or disposal.
For an overview of faults, see page 29.
• The following test equipment is required:
– Electronic flue gas emission meter for CO2 , CO and exhaust
temperature
– Pressure gauge for 0 - 30 mbar (resolution at least 0.1 mbar)
• Special tools are not required
• Permissible lucricants:
– For components in contact with water: Unisilkon L 641
(8 709 918 413).
– Unions: HFt 1 v 5 (8 709 918 010).
▶ Use 8 719 918 658 as heat conducting paste.
▶ Only use genuine spare parts!
▶ Refer to the spare parts catalogue when ordering spare parts.
▶ Always renew seals and O-rings removed during servicing or repair
work.
After inspection/maintenance

Inspection/Maintenance
To ensure that gas consumption and environmental impact remain as
low as possible over an extended period of time, we recommend that you
take out an inspection/maintenance contract with an authorised
contractor covering an annual inspection, and maintenance at other
times as required.
DANGER: Risk of explosion!
▶ Turn off gas valve before working on gas-carrying
components.
▶ Check for leaks before working on gas-carrying
components.
▶ Retighten all loosened threaded fittings.
▶ Recommission the appliance ( page 15).
▶ Check all connections for leaks.
