REMKO GPM
Unit description
Unit definitions
According to EU directives, the
units are defined as:
“Gas hot air heaters without
draught diverters with a fan
upstream of the heat exchanger”.
The units are fully automatic,
direct-fired hot air heaters for wall
and ceiling mounting.
They can be fired with natural gas
or LPG.
The units are used for constant or
temporary heating of closed and
open rooms, e.g. in:
Halls, workshops, greenhouses,
storage rooms, etc.
Unit classification
The units are classified by the
European standards EN 437 and
EN 1020 according to:
Gas category:
Classification of the types of
gases with which the units can be
operated.
For Germany DE II2ELL3B/P
Type of gas:
The burner can be operated with
gases of the second family (natural
gas groups H and L) and with
gases of the third family (butane
and propane).
Type of gas appliance:
Classification according to options
for discharge of combustion
products and supply of combustion
air. (Room sealed/non-roomsealed)
For further information, see
chapter “Installation of chimney
duct and combustion air supply
pipe”.
Unit design
The outside housing of the units
is made of coated sheet steel for a
long useful life.
The outlet air grille(s) is/are
located at the front.
To ensure optimal hot air
distribution in the installation
room, the horizontal fins of the
air outlet grille can be adjusted
manually.
The circulation air fan(s) with
outlet grille, exhaust fume
discharge and combustion
air supply connections, gas
connections, electric cable leadthroughs and plug connector for
mains connection are located at
the rear of the unit. Located on the
right side behind the inspection
door are the components
necessary for control and safety
such as
- the electrical circuit with wiring
- the control electronics
- the gas valve
- the modulating gas burner
The combustion chamber with
heat exchanger is located inside
the unit, directly in the circulation
air flow.
The combustion chamber is made
completely of Inox stainless steel
AISI 430.
Inox stainless steel AISI 441 is used
for the heat exchanger for higher
resistance to corrosion due to
moist vapours.
The special shape and large surface
of the combustion chamber and
heat exchanger ensure high
efficiency and a long service life.
The gas burner is also made
completely of specially machined
stainless steel.
Function of the units
GPM series modulating gas
wall heaters were developed for
heating rooms in industrial and
commercial premises.
The electronic control of the units
continuously regulates the heat
output between minimum and
maximum depending on the actual
heat demand.
Efficiencies of up to 94% can be
achieved with the premixing and
modulating technology.
The nominal heat output of the
REMKO GPM series is between
11.8 and 71.5 kW.
They essentially consist of the
combustion chamber with heat
exchanger and circulation air
fan(s).
The ambient air is sucked in by
the fan(s) and flows efficiently
via the burner chamber with heat
exchanger.
The combustion chamber is heated
by the gas burner and heats the
passing flow of air.
The air heated in this way is blown
out the front of the unit via an
adjustable air outlet grille.
Correct operation of the unit is
only possible with a connected
temperature control, e.g. ATR-6
(accessory).
NOTE
The units are not suitable for
domestic heating or similar.
6
Fans
The circulation air fans are
switched on by the control board
time-controlled, whereby time
control starts when the main
burner is switched on.
The delayed switch on prevents
cold air from being blown into the
room.
Switching off the unit
If there is no more heat demand
(room temperature above the set
value), the control board switches
off the burner.
The burner fan continues to run
for a preset time in order to cool
the combustion chamber.
The circulation air fan (possibly
also more than one) also continues
to run time-controlled until the
heat exchanger has cooled down.
If there is a renewed heat demand
during the after-running phase,
the control board will wait for the
fans to switch off and only then
perform a reset and begin with a
new cycle.
IMPORTANT INFORMATION!
Interrupting the power supply
during burner operation or the
residual heat removal phase must
be avoided as a lack of cooling of
the heat exchanger can lead to
considerable damage.
■
Overheating of the unit with
invalidation of the warranty
■
Damage to the burner fan and
its components
■
Operation of the safety
thermostat and associated
interlock of the safety
thermostat (STB).
The unit cannot be restarted
without manual reset
■
Damage to electric cables
Safety thermostat(s)
Each fan in the units has a safety
thermostat (STB) for manual reset.
Operation of the safety thermostat
triggers a safety shutdown.
The thermostat is arranged in
the area of the heat exchanger in
order to monitor the temperature
at its outlet.
Blocking of the unit caused by
operation of the safety thermostat
is indicated as fault F2 at the
temperature control.
ATTENTION
Before resetting a safety
device, the cause of its
operation must be located and
eliminated.
NOTE
Safety devices must not be
overridden or blocked during
operation of the unit.
Air/gas premixture
The units are provided with a
burner with complete air/gas
premixture.
Mixture takes place in the burner
motor fan.
The air sucked in by the fan flows
through the Venturi tube, where a
vacuum is produced, which draws
the gas.
This produces a constant air/gas
mixture. The ratio of air and gas
pressure is 1:1.
This value can be changed with
the offset regulating screw located
on the gas valve.
The gas volume is already adjusted
on delivery of the units and the
screw is sealed.
Fine adjustment can be made
with the adjusting screw on the
Venturi tube. This screw regulates
the maximum gas flow rate and
accordingly determines the carbon
dioxide (CO2) content of the
exhaust gases.
The screw is not sealed so as to
allow the hot air heater to be
changed to a different type of gas
if necessary.
NOTE:
For offset and CO2 adjustment.
The control board of the units
controls the burner motor speed
with DC current depending on the
room heat demand.
The air and accordingly the gas
flow rate changes with changing
speed.
The minimum and maximum fan
speeds are two values that cannot
be changed.

REMKO GPM
Burner operation
The heat demand for starting the
burner takes place via the set value
of the room temperature sensor in
the temperature control ATR-6.
For units both with and without
temperature control, the burner is
only started when the contact 7+9
on the terminal strip M1 is closed.
On receiving a heat demand,
the control board first starts the
burner fan so that the combustion
chamber is pre-aerated for a
certain time.
After pre-aeration, the control
board activates the flame
monitoring device ACF for igniting
the burner by energising the gas
solenoid valve EV1 and EVP, which
supplies the ignition gas burner.
In this way, the gas burner is
started.
The ignition monitoring electrode
monitors correct ignition of the
ignition gas burner.
When this operating condition is
detected, the control device of
the main gas valve EV2 opens to
supply the actual main gas burner.
After a certain time, while both
burners (ignition and main gas
burners) are operating at the
same time, the control board deenergises the solenoid valve EVP,
whereupon the ignition burner
extinguishes.
Flame monitoring for supervision
of the main gas burner is
continued by the monitoring
electrode.
The start program switches on the
main gas burner with an average
heat throughput of about 70%.
After about 30 seconds, the
burner starts to modulate the gas
flow rate and finally reaches the
adjusted gas flow rate.
During operation, the control
board regulates the gas flow rate
of the burner proportional to the
circulation air temperature, which
is measured by the NTC1 sensor at
the rear of the unit.

EfficiencyOperating cycle
The units offer the benefit of a
modulating mode of operation,
i.e. the produced heat output and
accordingly the gas flow rate (fuel
consumption) vary depending on
the heat demand.
With a reduced room heat
demand, the hot air heater
consumes less fuel, whereby its
efficiency is increased up to 94%.
Intrinsic safety
An increase in efficiency at
minimum output is achieved by
the use of a modern air/gas mixing
technology and simultaneous
regulation of the combustion air
and gas flow rate.
This technology increases the
safety of the unit as the gas valve
supplies the fuel depending on
the air flow rate according to its
factory setting.
In contrast to an atmospheric
burner, the CO2 content remains
the same over the entire control
range of the units and allows
an increase in efficiency with a
reduced heat output.
If there is no combustion air, the
valve does not release any gas.
With a reduction of combustion
air, the gas valve automatically
reduces the gas volume and keeps
the combustion parameters at an
optimal level.
Minimal pollutant emissions
The premixing burner allows in
conjunction with the air/gas valve
“clean” combustion with very low
pollutant emissions.
8
Modulation
The gas wall heaters are units
with gas burner modulation which
makes operation with diverse
outputs between minimum and
maximum possible. The maximum
output serves to quickly raise the
room temperature when the units
are switched on.
With the modulation feature
by contrast, the required room
temperature can be maintained
at a constant level with constant
variation of the heat output
appropriate to actual demand.
With this automatic adjustment
of the heat output to the
room conditions, the physical
phenomena of layer formation (the
tendency of heat to rise) can be
restricted due to the reduction of
the air supply temperature.
The temperature differences per
metre are below 0.5°C.
When the units operate with a low
heat output, efficiency above 94%
is achieved.
These results can only be achieved
by precise monitoring of the
climatic room conditions and
optimal control of the units.
For dimensioning heating centres
with hot air heaters, it is important
to observe the number of hourly
air exchanges.
In this respect, the following
should be noted:
Wall gas heaters should generally
be dimensioned so that the air
flow rate ensures a minimum of
two air exchanges per hour, even
if this is unnecessary for the heat
output.
The units have a room temperature
sensor NTC1 located at the rear
of the unit as standard so that
the temperature of the air sucked
in by the circulation air fans is
monitored.
Modulation takes place depending
on the value measured by this
sensor in a ratio to the value preset
on the microprocessor on the
control board.
Optimisation of the modulation
temperature value must take place
during operation of the system and
depends on the distance of the hot
air heater from the ground and
required temperature conditions.
The wall gas heater is normally
installed at a distance of 2.5 to 4 m
from the ground.
This ensures that the required
comfort temperature is reached
and maintained, whereby it is
important that the units are
operated at the lowest possible
modulation temperature which
is necessary to maintain these
conditions.
The modulation temperature (REG
SAN value) is factory set at 21°C.
This value allows an average
installation range between 3 and
5 metres at room temperatures
between 17 and 19°C
(see graph below).

REMKO GPM
Room correction
For this function, use of the
temperature control ATR.6 is
necessary.
A type of function is described
in the following that enables
maximum energy efficiency to
be achieved by the hot air heater
assisted by the control electronics
and temperature control.
In order to activate the ambient
correction function, the parameter
[C1] param k 11 must be set to 1.
The purpose of the room
correction function is to ensure
rapid heating at the beginning and
subsequently maintain the room
temperature at a constant level.
In this way, not only can layer
formation in the room air be
reduced, but also the fuel demand
reduced in particular.
The two correction reference
values are the temperature
measured by the sensor NTC2
(in the temperature control) and
the circulation air temperature
measured by the sensor NTC1 (at
the unit).
To activate the function, set the
parameter param k 17 to 1.
When the room temperature
approaches the setpoint value,
the modulation temperature is
changed linearly based on the two
parameters A16 and A24.
This makes it possible to operate
the unit on heat demand
at maximum output and to
quickly reach the preset room
temperature.
The heat output is subsequently
reduced which increases the
efficiency of the unit and the room
is heated with less hot air.
This enables the layer formation in
the room air and simultaneously
the heat loss to be reduced.
The units are supplied with the
following factory settings:
Modulation temperature:
„REG SAN“ 22°C
Neutral correction range:
A24 2°C
Correction coefficient:
A16 2
The parameter A24 determines
the range within which the
room temperature is corrected.
The parameter A16 offers the
possibility to increase the efficiency
of the temperature reduction
to the setpoint “REG SAN” as
shown on the graph. At the
standard setting, the modulation
temperature on reaching the room
temperature corresponds to:
„REG SAN“ =
24°C-(2°C x 2.5) = 19°C
The correction is independent of
the set room temperature.
The graph shows the room
temperatures [ST2] in relation
to the installation height of the
units „REG SAN“ during the initial
heating phase.
To deactivate the correction, set
the parameter [C1] param k 11 to
0.
When deactivating the correction,
the value “REG SAN” must be
correctly regulated in order to
avoid the following conditions:
- „REG SAN“ adjusted too high:
Strong layer formation with
high heat loss in roof area and
increased energy demand as a
consequence.
-
„REG SAN“ adjusted too low:
Time to reach the required room
temperature too long.
With correction deactivated, adjust
“REG SAN” so that the value is
higher than ST2 by the difference
in metres between the room and
modulation sensor multiplied by
0.4/0.5°C.
To change the modulation value
“REG SAN” on the temperature
control and to change all specified
values, see further back in the
manual.

General information Types of faults
The safety information on the
previous pages must be strictly
observed.
In exceptional circumstances, the
units can also be operated briefly
without temperature control.
For this purpose, the jumper on
terminals 7+9 on the terminal
strip M1 in the switchbox must be
The faults indicated and stored by
the control board (interlocks) have
the following causes:

The CR switch on the control
board must be set to OFF (see Fig.
on page 14) and the connector CN
with resistor (see Fig. on page 26)
plugged in.
- Operation of the safety
thermostat.
If the temperature detected
by the thermostat is too high,
the same operates and blocks
operation of the unit.
The faults F1 and F2 are caused by
safety devices and are therefore
permanent.
The fault still remains after
switching the mains off and
on again and can only be reset
manually.
The faults F3, F6 and F8 must be
reset manually or by switching the
mains off and on again.
In contrast, fault F4 is selfresetting:
After clearing the fault, reset takes
place automatically.
NOTE
For this mode, it is necessary to connect at least one
switching device, e.g. room
thermostat in order to be able
to switch the burner on and
off.
All information relating to the unit
and faults are now indicated via
LED indicators on the front of the
unit.
The green LED lights up to indicate
that the unit is connected to the
mains.
The red LED lights up to indicate a
fault on the unit.
The cause of the fault can
immediately be identified by the
different flashing/illuminating
states of the red LED:
F1
- LED shows a steady light
F2
- LED flashes twice rapidly
F3
- LED flashes three times
rapidly
F4
- LED flashes four times rapidly
F8
- LED flashes constantly
F6
- Red and green LED flash

F3
- Burner fan faulty; the
combustion air fan is faulty or
the signal to the control board
is outside the tolerance range
with respect to the requested
speed.
F4
- NTC1 sensor faulty or not
connected – the sensor value
is outside the measuring
range.
F6
- Control board fault due
to constant and repeated
unsuccessful ignition attempts
of the unit for a predefined
period.
With this fault, the fault
signalling LED located on the
control board also lights up.
F8
- The control board sent the
starting signal to the flame
monitoring device, but did
not receive the started signal;
it is possible that the flame
monitoring device is faulty.

Installation
The following instructions for
installation adjustment of the
units are intended exclusively for
authorised specialists.
The following safety information
must be observed.
General information
The units can normally be installed
directly in the room to be heated.
Installation of the units must
always take place in compliance
with the building regulations
(LBO) and the Ordinance on
Firing Installations (FeuVO) of the
respective federal state.
The First Ordinance on the
implementation of the Federal
Immission Control Act (1st
BImSchG) and the subsequently
issued statutory requirements of
the Ordinance on Small Firing
Installations (1st BImSchV) must
also be taken into account.
The installation of hot air heaters
operating with gas burners is
forbidden in the following rooms:
■
in public functional rooms or
in rooms with a person density
from 0.4 per square metre
■
in rooms in which gas or dust
can form due to the processes
occurring in these rooms or
through materials stored in
these rooms
To avoid dangerously high
voltages be reached, the distance
between the outer surface of
the unit and chimney pipe and
any possibly stored flammable
material at a distance to the floor
of 2.5 m or above must under no
circumstances be below 1.5 m.
Units with gas burner for gas
with a density above 0.8 (LPG,
propane, butane) may only be
installed in rooms in which the
floor is not below ground level.
Ventilation openings
Rooms in which gas-operated units
are used must have one or several
permanent openings (windows or
doors).
These openings must be provided
at the following points:
- directly below the ceiling for
gases with a density below 0.8;
- directly above the floor for
gases with a density above or
equal to 0.8.
Openings in outside walls must be
provided externally. The installed
heat output is decisive for the
cross-sectional sizes.
Installation instructions
The minimum height and distances
of the hot air heater from walls
and floors are shown in the diagram below.
The minimum distances are the distances necessary for maintenance.
All dimensions are in mm. The
height [2500 mm] corresponds
to the minimum height for “suspended units” as specified in the
applicable directives.

Standard wall bracket
Align the wall bracket against a
suitable point on the wall (spirit
level) and fasten securely.
Mark the holes to be drilled with a
pencil.
- Securely fasten the wall brackets
using suitable dowels and bolts
size M10 or larger.
NOTE
Ensure that the type of dowels
and size of the bolts are
suitable for the type of wall
and can support the weight of
the unit.
- Fit both pairs of brackets as
shown in the diagram using the
supplied material.
- Position the unit on the brackets
so that the holes in the unit
coincide with those in the
brackets, whereby the tips of the
brackets must be flush with the
front of the unit (except for GPM
75).
- Fasten the units with the M8
bolts provided, whereby a lock
ring must be inserted between
the bolt and bracket.
Hinged wall bracket
Instructions for fitting the hinged
brackets are supplied in the
packaging.
The use of hinged brackets is
recommended in the following
cases:
a) Installation of the unit in a
corner
b) Installation of the unit at a right
angle to the wall to which it is
fastened
c) Installation of the unit on a pillar
- When fitting the brackets, lock
the nuts by using a lock ring
between the brackets and nuts.

Chimney connection
Ceiling suspension
A ceiling installation set with horizontal air outlet is available as an
accessory for suspending the units using eyebolts. EDP No: 228765
The units operate in a closed
combustion system.
The fan is located upstream of the
heat exchanger.
The chimney duct and combustion
air supply must be planned and
executed in compliance with the
respective local regulations.
For outside wall installations, the
local master chimney sweep must
previously be consulted.
The various types of installation
are classified according to the
European standard EN 1020 and
DVGW-TRGI Directive 2008 and in
the factory supplied variant is part
of the EC approval.
The units are classified for the
following individual variants:
B2 3 /C1 3/C 33/C 43/ C53 / C63
Vertical air flow
Suspension of the units using
eyebolts with the air flow directed
downwards (installation with
vertical air flow).
A ceiling installation set with
vertical air outlet is available as an
accessory for this purpose.
It consists of eyebolts with special
fastener and additional fan
thermostats.
EDP No: 228766 to GPM 35

The chimney and air supply pipes
can be installed in different ways.
For example: Gas appliance type
B:
The combustion system is not tight
with respect to the environment in
which it is installed.
The combustion air is extracted
directly from the installation room.
This variant may only be installed
in rooms having at least one
door leading to the outside or
one window that can be opened
and having a cubic capacity of
minimum 4 m3 per kW total
nominal heat output of the unit or
a combustion air opening leading
to the outside of minimum 150
cm2 or two openings each having
a minimum free cross-section of 75
cm2.
22
We reserve the right to make changes to dimensions and design in the interest of technological advances.
For example: Gas appliance type C:
The combustion system is tight
with respect to the environment in
which it is installed.
The combustion air is supplied
from the outside.
The units must only be operated
with suitable chimney pipes.
The components available as
accessories from the factory
comply with all requirements as
standard.
ATTENTION
The use of plastic chimney
pipes must be avoided.
Condensation
If necessary, the chimney pipes
must be insulated to prevent the
formation of condensation in the
same.
The exhaust gas temperature at
minimum heat output corresponds
approximately to the condensation
temperature.
For pipe lengths above 5 m
indoors and 3 m outdoors,
condensation must be prevented
as follows:
■
By cladding the chimney pipes
■
By using condensate drains
from where the collected
condensation can be removed
from the chimney pipe.
Guide for selection
If the chimney end piece is not
connected directly to the unit,
but longer distances have to
be covered, it must be ensured
appropriate to the total length and
geometry of the chimney duct that
the end pieces and extensions as
well as the bends have the correct
diameter.
After determining the chimney
duct, the pressure loss for
the respective unit must be
determined.
The pressure loss varies for each
unit as the exhaust flow rate is
output-dependent.
Add up the determined pressure
losses of the individual chimney
components and ensure that the
total is not above the pressure
available for the type of unit to be
used.
If a combustion air supply pipe
exists, the pressure losses must
be added to those of the chimney
pipe.
If the total pressure losses are
above the available unit pressure,
chimney and fresh air pipes with a
larger diameter must be used.
In this case, calculation must be
repeated.
NOTE
The maximum possible pipe
lengths between the unit and end
piece are shown in the tables.
When using chimney bends,
it is necessary to take the
corresponding pressure losses into
account.
Pressure loss examples:
A 90° bend with Ø 80
corresponds to a 1.7 m straight
pipe length
A 45° bend with Ø 80
corresponds to a 0.8 m straight
pipe length
A 90° bend with Ø 100
corresponds to a 1.9 m straight
pipe length
A 45° bend with Ø 100
corresponds to a 0.9 m straight
pipe length
Examples of chimney pipe and
combustion air pipe arrangements
are shown on the following pages.
The units are classified for the
following individual installation
B2 3 /C1 3/C 33/C 43/ C53 / C63
variants:
Note:
Suitable condensate drains are
available as accessories.
These can be used for both
horizontal and vertical pipes.

straight through the outside wall
or
b) if the roof is simultaneously the
ceiling, with a vertical pipe via
the roof.
With this installation option,
adequate ventilation of the
installation room must be ensured
in order to provide a correct
combustion air supply.
This takes place by means of
openings in the room walls.
The dimensions and characteristics
defined in applicable standards
must be observed.
In particular, DVGW-TRGI 2008
Section 5.2.2. and TRF Section
7.2.2. must be observed.

out only by an authorised
installation company or factory
customer service engineers.
The following steps must be
carried out prior to commissioning:
ATTENTION
Only authorised specialists
may make adjustments and
carry out maintenance work on
the unit and gas burner.
1. Check all connections and
unions of the unit and gas
connection for tightness.
2. Check all accessible electrical
screw-type and plug connectors.
3. Check the electrical connection
for polarity and the mains
supply (230V/50Hz).
4. Check that the unit is
professionally connected to an
effective earthing system in
accordance with the applicable
safety standards.
Only when this is provided,
is electrical safety and reliable
function of the unit ensured.
ATTENTION
Gas pipes must never be
used for earthing electrical
equipment!
5. Check that the electronic
temperature control ATR-6 is
correctly connected.
The units are delivered preset
at the factory depending on the
required type of gas.
It must be ensured that a gas
supply pressure conforming to
standards is constantly available
depending on the type of gas
available locally.
The supplied gas must correspond
to the gas category set on the unit.
The procedure for commissioning
the burner is as follows:
1. Loosen the screwed cap in the
pressure measuring connection
of the burner.
Do not unscrew fully!
2. Connect a suitable pressure
gauge, e.g. U-tube manometer,
minimum resolution 0.1 mbar.
3. Open the gas shut-off devices.
4. Switch on the main/emergency
switch.
5. Adjust the room temperature
setting on the temperature
control ATR-6 to a higher
value than the existing room
temperature.
6. Set the mode selector switch
on the front of the unit to the
position “Heat”.
7. Set the temperature control to
“MANUAL MODE”.
8. Check that the heating symbol
lights up on the temperature
control display.
9. Adjust the heat demand
temperature higher than the
temperature measured by the
room thermostat or temperature
control.
A small flame lighting up on the
display shows that the burner is
switched on.
It is possible that the ignition
burner does not ignite first time
due to the presence of air in the
gas pipe, so that the unit generates
a fault.
The unit must be reset and the
starting procedure repeated.
ATTENTION
The complete unit must be
checked for correct functioning
and tightness of all gas
connections.
Combustion analysis
Start the burner and after
switching on the fan bring the
burner to “maximum output” by
pressing and holding the reset
button on the front of the unit for
2 to 3 seconds.
Operation at maximum output is
indicated by the green LED on the
front of the unit flashing once.
Ensure that the gas pressure
upstream of the gas valve
corresponds to the prescribed
value, otherwise regulate.
After about two minutes, connect
a gas analyser to the chimney pipe
and read off the CO2 value.
Compare this value with the values
in the “Gas settings“ table for the
type of gas used.

If the value is outside the specified
range, readjust with the CO2
regulating screw on the Venturi
tube.
- When the screw is tightened,
the gas flow rate decreases as
does the CO2 value.
- The CO2 value increases when
the screw is unscrewed.
Subsequently set the burner to
“minimum output” by pressing
and holding the rest button again
for 2 to 3 seconds.
Operation at “minimum output” is
indicated by the green LED rapidly
flashing twice.
Wait until the minimum output
at the burner has stabilised and
check that the CO2 value is equal
to or slightly below the CO2 value
at the maximum flow rate ( up to
-0.3%).
A deviating value can be corrected
with the offset screw.
To make changes to values,
remove the metal plug and turn
the regulating screw:
- the CO2 value decreases when
the screw is unscrewed,
- the CO2 value increases when
the screw is tightened.
After making any adjustments with
the offset regulating screw, the
CO2 value at maximum output
must be rechecked by carrying out
the above described steps.
After carrying out these steps,
set the burner to “normal” mode
by pressing and holding the reset
button again for 2 to 3 seconds.
This mode is indicated by the
green LED showing a steady light.
After carrying out all steps for
commissioning, the user must be

Maintenance
In order to ensure maximum
performance and a long service
life of the units, several checks
must be made once a year and in
any event before the start of the
heating season.
1) Check the condition of the
ignition and monitoring
electrodes as well as that of the
ignition gas burner.
2) Check the condition of the
supply air and chimney pipes as
well as the end pieces.
3) Check the Venturi tube for
clogging.
4) Check the heat exchanger for
fouling.
5) Check the gas pressure
upstream of the gas valve.
6) Check the function of the flame
monitoring device.
7) Check the safety thermostat(s).
8) Check the ionisation flow (> 2
microamperes)
NOTE
For steps 1, 2, 3 and 4, the
mains and gas supply to
the unit must always be
interrupted.
Steps 5, 6, 7 and 8 are carried
out with the unit in heating
mode.
1) Checking the electrodes
Dismantle the ignition burner
completely and clean the gas
system and gas nozzle with
compressed air.
Check the ceramic coating on the
electrodes for intactness.
Carefully remove any oxide
deposits on the metal part of the
electrodes with a very fine emery
cloth.
Check the electrodes for correct
seating (see diagram).
2-3 mm
It is important that the monitoring
electrode [IO] is located tangential
to the ignition burner head and is
not located within the same.

2) Checking the chimney and
supply air pipes
Visually inspect all pipes and
connecting pieces.
Any dirt deposits that have
accumulated on the end piece
of the supply air pipe must be
removed.
3) Checking and cleaning the
Venturi tube
Remove dirt deposits at the
entrance of the Venturi tube with a
brush or other suitable implement.
Ensure that no dirt falls in to the
Venturi tube.
4) Checking the gas supply
pressure
Ensure that the pressure upstream
of the gas valve corresponds to the
value prescribed for the respective
type of gas.
This check must be carried out
with the unit switched on at
maximum output.
5) Checking the flame monitoring
device
With the unit in heating mode,
close the gas valve and ensure that
fault F1 is indicated. Open the gas
valve again, reset and wait for the
unit to restart.
6) Checking the safety
thermostat(s)
This check must be carried out
with the unit operating in heating
mode.

7) Checking the ionisation flow
Carry out this check using a
tester that is able to measure
microamperes using DC current.
- Disconnect the unit from the
mains supply.
- Disconnect the cable from the
flame monitoring device and
connect it to the negative pole of
the tester.
- Establish a cable connection
between the positive pole of the
tester and the flame monitoring
device.
- Switch on the unit again and
measure the ionisation flow.
The ionisation flow value must be
above 2 microamperes (µA).
8) Checking and cleaning the heat exchanger
Due to the perfect combustion of
the units, only negligible deposits
normally accumulate here.
Nonetheless, deposits can
accumulate in the heat exchanger
tubes in the course of time. The
usual maintenance intervals must
therefore be observed in any
event.
A symptom of deposits in the heat
exchanger can be a noticeable
