Operating conditions for Buderus G and GE cast iron boilers
Thermostream technology is a unique feature of Buderus cast iron boilers. Return water is preheated and mixed within
the boiler before it comes in contact with the heated surface of the combustion chamber. The Thermostream technology
ensures there is an even temperature distribution in the boiler and avoids condensate forming within the combustion
chamber. This reduces thermal stress, the main cause of failure of normal cast iron boilers. The benefit of this
technology is that if the minimum boiler operating temperature of the boiler is maintained (see table below), there is no
need for a conventional shunt pump to be installed, saving the cost of a pump, the electricity it consumes and the
breakdown it can cause. The minimum boiler operating temperature as shown in the table below must be reached within
10 minutes and then be maintained while the burner is running.

1) This temperature has to be reached within ten minutes of the burner starting and has to be maintained whilst the burner is firing.
This operating condition can be easily achieved by the controls monitoring the boiler temperature and reducing the flow
rate through the boiler until the required temperature is reached. This is then maintained by continuing to control flow
based on the boiler temperature. The controls can reduce the flow rate by closing the valves on the mixed heating
circuits or by modulating the boiler primary pumps or by closing the motorised butterfly valves or by having a motorised
valve in the boiler return on a single boiler installation. The Buderus 4000 series controls can manage this process or
it can be done by the BMS.
Failure to ensure that the operating condition is maintained may lead to thermal stress in the boiler and eventual failure
of the sections which would be outside the scope of the warranty

Recommended wall clearances
B Observe the recommended wall
clearances for swinging out the burner
door, for boiler installation and for
cleaning and maintenance (Æ Fig. 6
and table below).
The burner door can be right or left hung/opening (the
boiler is always supplied with the door attached on the
right).
When installing your boiler maintain the recommended
minimum dimensions (shown in brackets). Select the
recommended clearances between wall and boiler to
enable easy access for installation, maintenance and
service work.
The wall clearance on the hinge side must be at least the
same as the amount by which the burner projects (AB).
A distance of AB + 100 mm from the wall is
recommended.

Positioning the boiler
Installing the boiler on a plinth or
foundation
A silencing boiler plinth is available as an
accessory from Buderus.
1
If this boiler plinth is not used, a concrete foundation can
be constructed on-site. When building the foundation, a
100 × 50 × 8 mm steel angle or 100 × 5 mm steel flat
should be incorporated to ensure that the boiler sections
can slide when the boiler is installed (Æ Fig. 7 and table
below).
B When building the foundations,
consider to which side the burner
swings out (left or right-hand burner
door stop, Fig. 6, page 15).
It is advisable to place the boiler on a 50 – 80 mm high
base (Fig. 7, [1]). The installation area must be
completely flat and level. The front edge of the boiler
should be flush with the edge of the foundation.

Boiler block assembly
Depending on the type of delivery, we distinguish
between delivery in loose sections and as ready
assembled block. When delivered as a block, the boiler
sections are already fully assembled and checked for
leaks prior to despatch. If, because of physical
limitations, a boiler block cannot be assembled as a
complete unit, delivery as loose sections would enable
the assembly on site.

B For wet-cleaning (chemical cleaning),
observe the operating instructions of
the relevant cleaning equipment and
cleaning agent.
It may be necessary to vary the wetcleaning process from that described
here.
B Select a cleaning agent that is appropriate for the
type of contamination (soot or encrustation).
B Cover the control unit with foil to prevent ingress of
the cleaning agent.
B Spray cleaning agent evenly from the top into the hot
gas flues
B Heat up the boiler to a boiler water temperature of at
least 70 °C.

14.5 Checking the system water pressure
A distinction is generally made between open vented
and sealed unvented systems. In practice, open vented
systems are seldom installed nowadays. We will
therefore be using a sealed system to demonstrate how
you can check the water pressure.

Open vented systems

In open systems, the hydrometer needle (Fig. 77, [1])
must lie within the red field (Fig. 77, [3]).
Sealed pressurised systems
In sealed systems, the pressure gauge needle
(Fig. 78, [2]) must be within the green field (Fig. 78, [3]).
Set the red needle (Fig. 78, [1]) on the pressure gauge
to the required system pressure.
B Bring the system up to the required
operating pressure.

NOTICE: Risk of system damage due to
frequent topping-up!
The system may be damaged, depending
on water quality, by corrosion or scaling, if
you frequently need to re-fill your system
with make-up water.

B Make sure that all air has been
removed from the heating system.
B Check the heating system for leaks and
the function of the expansion vessel.

System inspection and maintenance
The water pressure in the system is too low if the
pressure gauge needle (Fig. 78, [2]) falls below the
green mark (Fig. 78, [3]). Then re-fill the heating system
with top-up water (Æ Chapter 12.1 "Filling the system",
page 48).
NOTICE: Risk of system damage due to
temperature stresses!
B When the heating system is in
operation, never fill it via the boiler
drain & fill valve. Instead, only use the
filling valve in the heating system
(return).
B Top up with water via an WRAS approved filling
method.
B Vent the heating system.
B Check the water pressure once more.

15 Correcting burner faults
Heating system faults are output on the control unit
display. You will find detailed information regarding fault
displays in the service instructions for the relevant
control unit. The burner fault is also indicated by a fault
lamp on the burner.
NOTICE: System damage through frost!
The heating system can freeze up if it has
been switched off through a fault
shutdown.
B Rectify the fault immediately and
restart the heating system.
B Where that is not possible, drain the
heating and DHW pipework at the
lowest point.
NOTICE: System damage due to the reset
button being pressed too frequently.
The burner ignition transformer may be
damaged if you press the reset button
more than three times in succession when
the burner refuses to start.
B Do not attempt to remedy the fault by
pressing the reset button more than
three times in succession.
B Press the burner reset button (Æ burner operating
instructions).
If the burner does not restart after three attempts, refer
to the technical documentation provided with the burner
to find out how to reset it.
