The design and construction of the Buderus wall-
mounted condensing gas boiler 600 - 11R/19R/24R
conforms to the basic specifications listed in the
European directive governing gas-fired appliances
90/396/EEC, and with respect to EN 625, EN 483 and
EN 677.
Timber Framed Buildings
If the boiler is to be fitted in a timber framed building it
should be fitted in accordance with the Institute of Gas
Engineering document IGE/UP/7:1998.
Bathroom Installations
This appliance is rated IPX4D.
The boiler may be installed in any room or internal
space, although particular attention is drawn to the
requirements of the current IEE (BS.7671) Wiring Regu-
lations and, in Scotland, the electrical provisions of the
building regulations applicable in Scotland, with respect
to the installation of the boiler in a room or internal space
containing a bath or shower.
If the appliance is to be installed in a room containing a

It is not necessary to have a purpose-provided air vent
in the room or internal space in which the boiler is
installed. Neither is it necessary to ventilate a cupboard
or compartment in which the boiler is installed, due to
the low surface temperatures of the boiler casing during
operation; therefore the requirements of BS 6798,
Clause 12, and BS 5440:2 may be disregarded.
The permanent clearances required are:
in front: 8 mm
below: 21 mm
right side: 5 mm
left side: 5 mm
above: 21 mm
The position selected for installation MUST allow
adequate space for servicing in front of the boiler.
See table below:
in front: 350 mm
below: 50 mm
right side: 5 mm
left side: 5 mm
above: 200 mm
For the minimum clearances required for safety and
subsequent service, see the wall mounting template.
In addition, sufficient space may be required to allow
lifting access to the wall mounting plate.
Wall-mounted condensing gas boilers must only be
operated with the combustion air/flue gas systems espe-
cially devised and authorised for this type of boiler.
Observe the relevant standards, regulations and legisla-
tion of the country of final use.
The hydraulic resistance of the boilers is shown in the
graph below.

CAUTION!
CAUTION!
Use this device for its intended purpose
only.
WARNING!
DANGER!
notes relating to the heating system
water.
Thoroughly flush the system before it is
filled with water. Use only untreated water
or water treatment product such as
Sentinal X100 to fill and top up the
system.
When using water treatment, only prod-
ucts suitable for use with Buderus heat
exchangers are permitted (e.g. Sentinel
X100). Your warranty is at risk if an incor-
rect water treatment product is used in
conjunction with this appliance.
For more information, contact Buderus
Product Support Department.
It is most important that the correct
concentration of the water treatment
product is maintained in accordance with
the manufacturer's instructions.
If the boiler is used in an existing system
any unsuitable additives MUST be
removed by thorough cleaning.
BS.7593:1992 details the steps neces-
sary to clean a domestic central heating
system.
In hard water areas, treatment to prevent
lime scale may be necessary - however,
the use of artificially softened water is
NOT permitted.
Under no circumstances should the boiler
be fired before the system has been
thoroughly flushed.
Do not use water softened in a salt
bedding exchanger.
Do not use anti-freeze or other additives.
The expansion vessel must be of
sufficient size.
When oxygen-permeable pipes are used
(e. g. for floor heating systems) the
system must be separated by means of
heat exchangers. Unsuitable heating
water promotes sludge formation and
corrosion. This may cause malfunctions
and damage in the heat exchanger.
This appliance is not suitable for gravity
central heating nor are they suitable for
the provision of gravity domestic hot
water.
The boiler must be vented.
Drain cocks must be located in accessible
positions, which permits the draining of
the entire system. They should be at least
½" BSP nominal size and be in accord-
ance with BS 2879.

Safe handling of substances
Care should be taken when handling the boiler's insula-
tion, which can cause irritation to the skin.
No asbestos, mercury or CFCs are included in any part
of the boiler and its manufacture.
Open vent system requirements
The system should be vented directly off the boiler flow
pipe, as close to the boiler as possible. The cold feed
entry should be inverted and MUST be positioned
between the pump and the vent, and not more than
150 mm away from the vent connection.
There should be a minimum height, 450 mm, of open
vent above the tank water level. The vertical distance
between the highest point of the system and the
feed/expansion cistern water level MUST not be less
than 1000 mm. The pump must be fitted on the flow side
of the boiler.
A suitable pump is a domestic circulator capable of
providing a maximum 11 °C temperature differential
across the boiler with the whole of the heating circuit
open. With the minimum flow circuit allowed by the
controls the differential must not exceed 25 °C
(see also the graph on page 5).
The vertical distance between the pump and
feed/expansion cistern MUST comply with the pump
manufacturer’s minimum requirements, to avoid cavita-
tion. Should these conditions not apply either lower the
pump position or raise the tank above the minimum
requirements specified by Buderus. The isolation valves
should be fitted as close to the pump as possible.
The system will work more efficiently when the flow
temperature is as low as possible.
NOTE:
notes relating to domestic hot water.
The boiler must not be used for direct hot
water supply.
The hot water storage cylinder must be of
the indirect type.
Primatic cylinders are not recommended
and must not be used on sealed systems.
The hot water cylinder and ancillary
pipework, not forming part of the useful
heating surface, should be lagged to
prevent heat loss and any possible
freezing - particularly where pipes run
through roof spaces and ventilated under-
floor spaces.
The domestic hot water service must be in
accordance with BS 5546 and BS 6700.

Schematic pipework
The boiler does not normally need a bypass but is
required when using 2 port zone valves. Lock shield
valves are required on the radiators in the area where
the thermostat is situated.
Thermostatic radiator valves
An automatic bypass is always required.
To comply with the building regulations that heating
systems utilising the thermostatic radiator valve control
of temperature in individual rooms shall also be fitted
with a room thermostat, controlling the temperature in a
space served by radiators not fitted with such a valve.
Such an arrangement will provide for potentially more
efficient control of the environment and will also avoid
the continuous running of the circulation pump during
programmed heating ON periods - thus saving electrical
energy.
It is, therefore, strongly recommended that, when ther-
mostatic radiator valves are used, space heating
temperature control over a living/dining area or a
hallway having a heating requirement of at least 10% of
the minimum boiler heat output, is achieved using a
room thermostat whilst other rooms are individually
controlled by thermostatic radiator valves.

The installation must comply with the requirements of
BS. 6798 and BS. 5449.
All components of the system, including the heat
exchanger of the indirect cylinder, must be suitable for a
working pressure of 3 bar and temperature of 110 °C.
Care should be taken in making all connections so that
the risk of leakage is minimised.\
2. Safety valve
A spring loaded safety valve complying with the relevant
requirements of BS. 6759 must be fitted in the flow pipe
as close to the boiler as possible and with no intervening
valve or restriction. The valve should have the following
features:
A non-adjustable preset lift pressure not exceeding
3 bar;
A manual testing device;
Provision for connection of a discharge pipe. The
valve or discharge pipe should be positioned so that
the discharge of water or steam cannot create a
hazard to the occupants of the premises or cause
damage to electrical components and wiring.
3. Pressure gauge
A pressure gauge covering at least the range of 0-4 bar
must be fitted to the system. The gauge should be easily
seen from the filling point and should preferably be
connected at the same point as the expansion vessel.
4. Expansion vessel
A diaphragm type expansion vessel must be connected
to a point close to the inlet side of the pump, the
connecting pipe being not less than 15 mm size and not
incorporating valves of any sort.
The vessel capacity must be adequate to accept the
expansion of the system water when heated to 110 °C.
The charge pressure must not be less than the static
water head above the vessel. The pressure attained in
the system when heated to 110 °C should be at least
0.35 bar less than the lift pressure of the safety valve.
For guidance on vessel sizing refer to table 1.
For further details refer to BS. 5449 and BS. 7074:1 and
the British Gas Corporation publication: "Material and
Installation Specifications for Domestic Central Heating
and Hot Water".
5. Cylinder
The cylinder must be either of the indirect coil type or a
direct cylinder fitted with an immersion calorifier which is
suitable for operating on a gauge of 0.35 bar in excess
of the safety valve setting. Primatic cylinders are not
suitable for sealed systems.
6. Make-up water
provision must be made for replacing water loss from the
system, either:
from a manually filled make-up vessel with a readily
visible water level. The vessel should be mounted at
least 150 mm above the highest point of the system,
and be connected through a non-return valve to the
system, filled at least 300 mm below the make-up
vessel on the return side of the domestic hot water
cylinder or radiators.
or
where access to a make-up vessel would be difficult
by pre-pressurisation of the system. Refer to "Filling",
below.
7. Mains Connection
There must be no direct connection to the mains water
supply or to the water storage tank supplying domestic
water, even through a non-return valve, without the

Installation1
1.6 Pipe connections
Buderus advises to use copper piping for the first
600 mm, then it is allowed to switch to another approved
pipe material.
z Take the CH flow connection pipe and the CH return
connection pipe out of the box and connect to the
condensing gas boiler (fig. 4, item 1 and 2).
z Connect the central heating system to these pipe
connections according to the relevant standards.
1.6.1 Gas Supply
The gas installation must be installed in accordance with
BS.6891.
The complete installation MUST be tested for gas
tightness and purged as described in IGE/UP/1b.
1.6.2 Gas connection
z A gas service valve is supplied with the unit. Take it
out of the box and connect it to the boiler see fig. 4,
item 3 with approved P.T.F.E.-tape. Connect to gas
supply according to the relevant standards.
1.6.3 Water circulation system
The central heating system should be installed in
accordance with BS.6798 and, in addition, for smallbore
and microbore systems, BS.5449 or EN 12823.
1.6.4 Condensate removal
Positioning and termination of the condensate drain
pipe
The condensate pipe should be run and terminate
internally to the house soil and vent stack or waste pipe.
Alternatively, the condensate can be discharged into the
rainwater system if connected to a foul water draining
system, or into a purpose-made soak away (condensate
absorption point).
All connecting drainage pipework should generally have
a fall of at least 2.5° to the horizontal, or approximately
50 mm per metre of pipe run. If this is can not be
achieved, consider the use of a condens pump.

CAUTION!
CAUTION!
Ensure that all pipework is routed so as to
minimise any strain on the boiler fittings.
CAUTION!
CAUTION!
Pipework from the meter to the boiler
MUST be of adequate size.

Installation 1
If an external pipe run is unavoidable then the run should
be insulated with water proof insulation limited to 3 m in
length. Should this be exceeded then the pipework
diameter should be increased to 32mm and the
pipework insulated using weather proof materials.
It should be noted that the connection of a condensate
pipe to a drain may be subject to local building controls.
Material for condensate
The condensate drainage pipe should be run in a
standard drain pipe material, e.g. PVC (polyvinyl
chloride), PVC-U (unplasticized polyvinyl chloride),
BS (acrylonitrile-butadienestyrene), PP (polypropylene
polyprolene) or PVC-C (cross-linked polyvinyl chloride).
The condensate drain can be attached to the syphon
(fig. 5).
Any internal pipework should be of a diameter to match
the requirements of the condensate exit pipe on the
appliance.
Internal termination to internal stack
The condensate drainage pipe should have a minimum
outside diameter of 1" with no length restriction. It should
incorporate a trap with a 75 mm condensate seal and be
connected to the stack at a point at least 450 mm above
the invert of the stack. The trap built into the boiler will
provide this 75 mm (fig. 6) condensate seal.
WARNING!
WARNING!
Any external run must be insulated with
water proof insulation.

Ensure that the condensate trap is filled

Installation1
External termination via internal branch (e.g. sink
waste)
The condensate drainage pipe should have a minimum
outside diameter of 1" with no length restriction. The
connection should preferably be made downstream of
the sink waste trap. If the connection is only possible
upstream, then the air break is needed between the two
traps. This is normally provided by the sink waste pipe
(see fig. 7 and 8).
Condensate absorption point
The condensate drainage pipe should have a minimum
outside diameter of 1" and the external pipe length
should not be more than 3 m. The condensate
absorption point should be sited in a convenient position
as close as possible to the boiler but not in the vicinity of
other services. See fig. 9 for information.

NOTE
When discharging condensate to an

ensure blockage cannot occur during
freezing conditions. If this is likely to
occur, the use of a syphon trap is
recommended.
