Models and output
The floor standing gas condensing boi-
ler R600 EVO is available in 7 types
within an output range from 142 until
540 kW.
Application possibilities
The gas condensing boiler R600 EVO
is applicable for alle central heating
systems built according to EN12828. In
cascade applications (max. 8 boilers
with LMS14 master/slave cascade con-
trol) the R600 EVO can cover installati-
ons up to 4300kW.
Preferred applications are central hea-
ting and sanitary hot water production
in multi-family buildings, municipal and
industrial buildings.
Value propositions

proven technology with exceptional
high quality
Highest system flexibility
easy planning and Plug & Play instal-
lation with pre-assembled system kits
Easy maintenance
boiler design optimised for easy ac-
cess on servicing
Unequalled lifetime high efficiency
corrosion resistant stainless steel
heat exchanger
Environmental friendly
lowest emission values
Description
The R600 EVO is a fully modulating
boiler. The control unit of the boiler
adapts the modulation ratio automati-
cally to the heat demand requested by
the system. This is done by controlling
the speed of the fan. As a result, the
Whirlwind mixing system will adapt the
gas ratio to the chosen fan speed, in
order to maintain the best possible
combustion figures and therewith the
best efficiency. The flue gases created
by the combustion are transported
downwards through the boiler and
leave at the back side into the chimney
connection.
The return water from the system en-
ters the boiler in the lower section,
where is the lowest flue gas tempera-
ture in the boiler. In this section con-
densation takes place. The water is
being transported upwards through the
boiler, in order to leave the boiler at the
top (burner) section. The cross flow
working principle (water up, flue gas
down) ensures the most efficient com-
bustion results.

Boiler transport
Boiler installation
Boiler installation
The boiler should be positioned in a
frost-proof boiler room. If the boiler
room is on the roof, the boiler itself may
never be the highest point of the instal-
lation.
When positioning the boiler, please
note the recommended minimum clea-
rance in the picture. When the boiler is
positioned with less free space, mainte-
nance activities will be more difficult.
To optimize the position of the boiler in
the room it is possible to exchange the
position of the electrodes from the right
side of the boiler to the left side of the
boiler.
This also means that the required
space as indicated in the picture will be
mirrored.
Normal: Left 250mm / Right 450mm
Modified: Left 450mm / Right 250mm
Once the boiler is in the correct
position, the adjustable feet (2)
(with vibration absorption dampers)
should be adjusted to the right height
and the boiler should be horizontal.
Ensure that the wheels are not in
contact with the floor!
Water and gas connections should be
done after adjusting the feet, as they
affect the exact height of all connec-
tions.
The (inter)national and local norms for
the installation of heating systems
should be respected at all times.

Maintenance
Regular maintenance is necessary to
secure a safe and economical operati-
on of the installation. For the R600
EVO, one annual maintenance visit is
recommended. During this visit, the
proper functioning of the complete hea-
ting system should be checked as well.
Water quality
The lifetime of the complete heating
system is affected by the water quality.
Additional costs for water treatment of
an installation are always lower than
repairing costs for damage created by
poor water quality.
Fuel
The gas condensing boiler R600 EVO
is applicable for gases G20, G25, G30
and G31. Factory settings are always
done for G20. For other types of natural
gas, a correction can be made on the
gas valve. For LPG, it’s necessary to fit
a restriction plate (included in delivery)
before operating the boiler.
The R600 EVO can work with gas pres-
sures up to 50 mbar. In case of a gas
pressure above 50 mbar, a pressure
regulator should be fitted in the gas line
(available as accessory).
The gas consumption and gas pres-
sures of the different gases can be
found in the chapter „Technical data“.
Combustion air
The gas condensing boiler R600 EVO
can be used in both non-roomsealed
and roomsealed applications. The com-
bustion air to the boiler shouldn’t con-
tain high concentrations of dust and/or
halogen, as they can damage the heat
exchanger surface. Especially in buil-
dings, where chemicals are used, the
combustion air facility should prevent
these chemicals to enter the boiler.
The different room sealed connection
possibilities the R600 EVO is approved
for, can be found in the chapter „Flue
gas system“.
The following water quality levels must
be respected at all times for warranty
claiming. Damage to the boiler due to
poor water quality will not be taken un-
der warranty.
The system should be filled with water
with a PH value between 7,0 and 9,5.
The chloride value of the water should
not exceed 50 mg/l. Entry of oxygene
by diffusion should be prevented at all
times. Damage to the heat exchanger
because of oxygene diffusion will not
be taken under warranty.

In installations with higher water volu-
mes, it’s necessary to respect the maxi-
mum filling and additional volumes with
corresponding hardness values as sta-
ted in the german VDI2035 standard. In
the table you can find the nominal va-
lues for filling and additional water for
the R600 EVO according to the the
VDI2035.
The table at the left gives an indication
of the relation between the water quali-
ty and the maximum water filling volu-
me during the lifetime of the boiler.
Consult the original text of the VDI2035
for more detailed information.
Constant entry of oxygene in the instal-
lation should be avoided. The system
water pressure should be higher than
the atmospheric pressure in all parts of
the installation. Underfloor heating
components without oxygen diffusion
barrier should never be used. When
they’re used anyway, a system separa-
tion (f.e. with plate heat exchanger) is
compulsory.

Noise protection
The gas condensing boiler R600 EVO
is equipped with a patented premix
burner. The noise level of this very
quiet premix burner is extremely low in
comparison to conventional gas
burners. Therefore no further measures
have to be taken for noise protection in
the boiler room.
Antifreeze
The R600 EVO can be used with the
antifreeze type Shell Antifreeze Con-
centrate. The concentration of the anti-
freeze in the system affects the maxi-
mum capacity the boiler can work on.
The relation between antifreeze con-
centration and capacity reduction of the
boiler can be found in the graph.
The maximum percentage of antifreeze
should not exceed 30%.
The R600 EVO is supplied with ad-
justable feet, which also prevent the
transmission of vibration noise from the
boiler into the building.
Noise created by system components
(f.e. pumps) should be taken care of
with external measures, in case of hig-
her noise level requirements.

Requirements and regulations
Regulations for the construction of flue
gas systems are very different for each
country. It should be ensured that all
national regulations with regard to flue
gas systems are respected. The most
important national norms can be found
in the chapter „Norms“.
Pay attention to the following recom-
mendations when dimensioning a flue
gas system:
- Only approved flue gas material may
be used.
- The flue gas system must be properly
calculated to ensure a safe functioning
of the system.
- Flue gas system components should
be removable for maintenance purpo-
ses.
- Horizontal flue gas ways must be
mounted under an angle of 3º mini-
mum.
A separate condensate drain for the
chimney is not necessary, as the con-
densate can enter the drain via the
syphon connection of the boiler.
The R600 EVO is certified for the flue
gas systems B23 and C63.
Materials
Exclusively materials, which are heat
resistant and resistant to flue gases
and aggressive condensate, may be
used.
The R600 EVO has an integrated high
limit thermostat function for the flue
gaes. When the fluegas temperature
exceeds 100ºC, the burner is switched
off. With this function, an additional
(external) safety device is not necessa-
ry.

Flue gas system
Dimensioning
16
Dimensioning
When dimensioning a flue gas system,
it’s necessary to perform a calculation
check of the flue gas system in order to
verify if the choosen system is appli-
cable.
The following table shows two
examples of possible flue gas systems,
including the maximum possible height
of the system. These examples only
give an indication of the possible
heights, but they can not be used for
official flue gas layout calculation. Each
flue gas system must be calculated by
an authorized company.
The maximum negative flue gas pres-
sure, which doesn’t affect the burner
modulation ratio, is 30 Pa. Higher nega-
tive pressure will lead to limitation of
the burner modulation ratio.
The maximum horizontal flue gas way
is 20m. With horizontal ways longer
than 20m, a faultless burner start in
cold condition can not be guaranteed.

General
Condensate, created by the R600 EVO,
should be drained into the public drai-
ning system. The condensate PH is
between 3.0 and 3.5. National and/or
local regulations have to be checked, in
order to find out whether the condensa-
te should be neutralised before entering
the public draining system.

Neutralisation systems
The neutralisation systems can be
placed in the bottom section of the boi-
ler. The delivery of the system contains
the following components:
 Granulate for first filling
 Connection hoses for inlet and outlet
connection
 Boiler connection adapter
For the neutralisation two different sys-
tems are available:
Standard neutralisation system (DN)
The standard neutrlisation system is used, when the public draining connection is
at lower level than the boiler syphon connection.
Neutralisation system with pump (HN)
The neutralisation system with pump is used, when the public draining system is at higher level than the boiler syphon
connection and the condensate needs to be transported to a higher level before draining is possible. The built-in pump of the
neutralisation system takes care of the transport of the condensate.
The maximum amount of condensate
for each boiler type can be found in the
chapter „Technical data“.

Hydraulic connection

Water flow data

Hydraulic resistance
The hydraulic resistance depends on
the flow rate through the boiler and the
boiler type. In the graph the resistance
for a specific flow rate can be found.
The R600 EVO is able to control a
speed controlled pump via PWM or a
0-10VDC signal. It makes the flow rate
modulate in parallel with the burner
load. The minimum flow rate, to which
the pump is allowed to modulate with
the burner load, is 30% of the nominal
flow rate through the boiler.
The flow rate through the boiler can
also be checked by calculation. This
can be done with a ∆T as well as a ∆p
measurement.
∆T-measurement
Check the temperature difference over
the boiler (∆T flow-return) when the
boiler is running on 100% load. The
nominal ∆T is 20K and must be at least
between 10K and 30K for secure boiler
operation. An indication of the actual
flow rate can be found with the follow-
ing calculation (see table below for
nominal data):
∆p-measurement
Check the pressure difference over the
boiler (∆p flow-return) when the boiler
pump is running (burner on is not re-
quired). The nominal ∆p for each boiler
type can be found in the table below,
actual ∆p must be within:
0.45*Δpnom ≤ ∆p ≤ 4*∆pnom. An indication
of the actual flow rate can be found with
the following calculation (see table be-
low for nominal data):
qactual = (∆Tnominal / ∆Tmeasured) * qnominal
qactual = √(∆pmeasured / ∆pnominal) * qnominal

Hydraulic connection into a system
The R600 EVO must be connected in
such a way, that a minimum flow rate of
30% of the nominal flow rate can be
ensured at all times, independent from
the flow rate in the secundary system.
This can be achieved by using one of
the following 3 possibilities:
 Standard, with low loss header or
plate heat exchanger
 Bypass, with integrated minimum flow
rate by Bypass pump*
 Split System, with 2 return connec-
tions for best possible efficiency
(warm and cold return)
* only applicable in single boiler instal-
lations
Standard
This is the most common way to con-
nect the boiler to the system. By using
a low loss header or plate heat exchan-
ger a minimum flow rate can be ensu-
red at all times, independent from the
flow rate in the secundary system. The
boiler pump is available as a speed
controlled version. The speed control-
led pump mudulates the flow rate in the
primary system in parallel with the bur-
ner load. This ensures the lowest possi-
ble return temperature to the boiler for
high efficiency usage.
Details of the available pump kits can
be found in the chapter „Accessories“.
Bypass
In single boiler installations, the R600
EVO can also be used without low loss
header or plate heat exchanger. For
this solution a bypass kit is available as
accessory to the standard boiler. The
bypass is connected between the flow
connection and the second return
connection of the boiler.
The performance of the bypass pump is
very low when the system flow rate is
high. As soon as the system flow rate
decreases, the bypass pump perfor-
mance increases to ensure a minimum
flow rate through the boiler.
The bypass pump does not transport
the water from the boiler into the
system. The system pump should
overcome the boiler resistance at
nominal flow rate to transport the
from the boiler into the system and
vice versa.
Details of the available pump kits can
be found in the chapter „Accessories“.
Details to the 3 possibilities mentioned
above, can be found in the next sec-
tions.
Bypass
Standard

Hydraulic connection
Split System
20
Split System
The split system boiler enables the
connection of two returns with different
water temperatures. By evasing the low
loss header the cold return water enters
the condensor of the boiler directly,
without mixing with the high temepra-
ture return water (f.e. from an air heater
circuit). This hydraulic separation in-
creases the efficiency of the system.
The primary boiler pump, controlled by
the boiler managemant unit, ensures a
minimum water flow through the boiler
except for the bottom heat exchanger
(condensor). The system pump of the
low temperature circuit must be dimen-
sioned in such a way, that it can over-
come the boiler resistance.
The nominal flow rate in the (warm)
boiler circuit must be minimum 50%
of the total nominal flow rate through
the boiler.
More info about the 2nd return connec-
tion can be found in the chapter
"Accessories".
The following data can be used for the dimensioning of the pumps in a split system.
