3.3.3. System pump
The boiler does not have a built-in pump. A system pump can be
installed on the connector of the standard control PCB. This can be
an on/off pump or a modulating pump (with 0 - 10 V control).
3. Technical description Gas 310 ECO PRO - Gas 610 ECO PRO
14 160514 - 125467-05
¼For more information on controlling a modulating pump, See
paragraph: "Electrical connections", page 36.
Parameters p43 and p44 are used to modify the pump settings.
¼See the Installation and service manual HMI GAS 310/610 ECO
PRO for comprehensive operating instructions. This includes
information about changing and reading parameters, the meaning of
fault codes and deleting the failure memory.
3.3.4. Regulation of the water temperature
The boiler is equipped with electronic temperature control based on
flow, return, and boiler block temperature sensors. The flow
temperature can be set between 20°C and 90°C. The boiler reduces
its power when the set outlet-temperature is attained. The cutout
temperature is the set heating outlet-temperature + 5 °C.
3.3.5. Protection against a shortage of water
The boiler is fitted with a safety device to prevent the shortage of water
based on temperature measurements (Temperature difference
between flow and return). If ΔT = 25 K is reached (factory setting),
the boiler reduces its output by modulating to remain in operation as
long as possible. If ΔT ≥ 25 K the boiler goes into part load. If ΔT >
25 + 5 K the boiler goes into a normal control stop (blocking).
3.3.6. Maximum temperature protection
The maximum protection switches the boiler off if the water
temperature is too high (110°C) and locks it on the control box (Fixed
value, cannot be modified). Once the fault has been rectified, the
boiler can be reset by pressing the J button for 2 seconds.
3.3.7. Air differential pressure switch
Before a start and when the boiler is in operation, the air pressure
differential switch PS measures the difference in pressure between
the measuring points at the rear of the heat exchanger p+ and the air
box p-. If the pressure difference is greater than 6 mbar, then the boiler
will lock out. Once the fault has been rectified, the boiler can be reset
by pressing the J button for 2 seconds.

4.6.4. Additional Directives
4Please refer to the manufacturer’s instructions for the material in
question when installing the flue gas discharge and air supply
materials. If the flue gas discharge and air supply materials are not
installed according to the instructions (e.g. they are not leakproof,
not clamped in place etc.), this may cause hazardous situations
and/or result in bodily injury. After assembly, check at least all flue
gas and air–carrying parts for tightness.
4Connection of the combustion gas exhaust directly to the buildings
brick chimneys or flues is forbidden for condensation reasons.
4Always clean the ducts thoroughly in cases where lining pipes are
used and/or a connection of the air-supply.
4It must be possible to inspect the flue or chimney.
4In cases where condensate coming from the stainless steel or
plastic sections of the flue gas pipe can be driven back towards
the aluminium section, this condensate must be removed using a
collecting device before the aluminium section is reached.
4For long, aluminium, combustion-gas exhaust pipes it is initially
necessary to consider the relatively high quantity of corrosive
products which are brought together with the condensate from the
exhaust pipe. The siphon on the equipment requires regular
cleaning or, preferably, an additional condensate collector can be
installed above the equipment.
4The combusted gas discharge pipe must be sufficiently inclined
towards the boiler (at least 50 mm per metre) and an adequate
condensate collection tank and discharge system constructed (at
least 1 m before the boiler opening). The elbows fitted must be at
more than 90° to guarantee the provision of an adequate gradient
and tightness on the lip rings.
Please contact us for further information.
4.6.5. Connection of the combustion gas exhaust
pipe
The boiler is equipped with a mechanical flue gas non-return valve as
standard. This prevents flue gas travelling back up into the boiler
when it is not in operation. (E.g. for cascade systems).
Mounting
1. Fit the combustion product discharge conduit.
Gas 310 ECO PRO - Gas 610 ECO PRO 4. Installation
160514 - 125467-05 35
2. Fit together the combustion gas exhaust pipes, without welding.
4The pipes must allow no leakage of flue gases and be
resistant to corrosion.
4Connect the pipes together without stress between
the sections.
4Maximum bracket distance from vertical pipes is 2 m.
4Maximum tilt of vertical pipes is 20 mm/m.
4The pipes must not rest on the boiler or flue gas
adapter.
4The horizontal sections need to be constructed with a
gradient of 50 mm per metre: Back to the boiler.
4Use a bracket at each connection from horizontal
pipes.
4.6.6. Connection of the air intake pipe
Mounting
1. Fit the air-intake conduit.
2. Fit the air-intake conduits together without welding.
4The pipes must be airtight and corrosion-resistant.

If the central heating system is not used for a long period, we
recommend switching the boiler off.
4Switch the On/Off switch to Off.
4Switch off the boiler electrical power supply.
4Shut off the gas supply.
4Ensure that the boiler and system are protected against frost
damage.
CAUTION
In the event of low temperatures, we recommend that the
installation continues to operate at a lower temperature.
This prevents freezing.
6.2 Antifreeze protection
CAUTION
Drain the boiler and central heating system if you are not
going to use your home or the building for a long time and
there is a chance of frost.
1. Set the temperature control low, for example at 10°C.
If there is no demand for heat, the boiler will only switch on in order
to prevent frost damage.
When the heating water temperature in the boiler falls by too much,
the integrated protection system in the boiler starts up. This protection
functions as follows:
(The circulation pump must be electrically connected to boiler)
4The circulation pump switches on if the water temperature is lower
than 7°C.
4If the water temperature is lower than 4°C, the boiler starts up.
4If the water temperature is higher than 10°C, the boiler shuts down
and the circulation pump continues to run for a short time

7 Checking and maintenance
7.1 General
The cast aluminium/silicon heat exchanger forms the heart of the
boiler. When combined with the special geometric shape, the flue gas
pollution remains limited. At the top of the heat exchanger, the space
between the pins of the heated surface on the flue gas side is slightly
larger than further down. This ensures quick distribution of the hot flue
gases over the heat exchanger which avoids an excessive load at the
top. Due to the boiler’s modulating operation, condensation occurs in
different locations in the heat exchanger. This ensures that most of
the oxidation residues produced are dissolved and rinsed away. The
self-cleaning operation therefore functions optimally.
Nevertheless, we recommend cleaning the flue gas side of the heat
exchanger thoroughly during the annual inspection and service.
Adjust the frequency of inspection and service to the
conditions of use. This applies especially to boilers in
constant use (for specific processes).
7.2 Standard checks
For work on the boiler Gas 610 ECO PRO: The features
and instructions described are for each boiler module.
CAUTION
During inspection and maintenance operations, always
replace all gaskets on the parts removed.
When it is observed subsequent to inspection or
maintenance work that a component in the boiler needs to
be replaced, use only original spare parts or recommended
spare parts and equipment. A service set containing all
necessary components is available for standard
maintenance.
We recommend carrying out the standard checks in the following
order:
1. Checking the hydraulic pressure.
2. Checking the ionization current.
3. Check the water quality.
4. Checking the air supply connections and flue gas discharge
connections.
5. Checking the gas filter for pollution.
6. Checking combustion.
7. Check the air supply hose.
8. Check the dirt trap.
9. Check the air box.

8 Troubleshooting
8.1 Shutdowns and lock-outs
For operation of the boiler Gas 610 ECO PRO: The
features and instructions described are for each boiler
module.
8.1.1. General
The boiler is fitted with an electronic regulation and control unit. The
heart of the control system is a microprocessor, the Comfort
Master©, which controls the boiler and also protects the boiler. When
a failure is signalled, the boiler stops or becomes locked.
¼See the Installation and service manual HMI GAS 310/610 ECO
PRO for comprehensive operating instructions. This includes
information about changing and reading parameters, the meaning of
fault codes and deleting the failure memory.
8.1.2. Blocking
A (temporary) blocking mode is a boiler operating function caused by
an unusual situation. In this case, the display gives a code of blocking
(code 5t[9). The boiler control will try to re-start several times.
The shutdown codes can be read out as follows
1. Press the two f keys simultaneously.
2. Confirm by pressing key S. 5t is displayed, alternating with
the shutdown code 9.
3. Press the [+] key. 5v appears on the display.
The boiler starts up again automatically when the reason
for the blocking has been removed.
8.1.3. Lock out
When a failure is signalled, the boiler stops or becomes locked. The
display shows :
In a red flashing display:
4The symbol c
4The symbol J
4The fault code (for example e[01)
T001632-B
8. Troubleshooting Gas 310 ECO PRO - Gas 610 ECO PRO
74 160514 - 125467-05
The boiler can only start operating again once the causes
of the lock-out have been rectified and after pressing the
J key
8.1.4. Error memory
The boiler control is equipped with an error memory. The last 10 errors
encountered are recorded in this memory. Each new input deletes the
oldest entry from the memory. In addition to the error codes, the
following data are also saved:
4Number of times that the error occured: (MK[xx).
4Boiler operating mode selected (5t[xx).
4The flow temperature (t1[xx) and the return temperature
(t2[xx) when the error occured.
