4Installation
4.1 Positioning
•Check that the support is solid enough.
•The heater is designed as free hanging. The heater
should be able to blow the warm air free from any ducting
or obstacles. Also the air intake should be free.
•Keep sufficient distance between the heater and any
obstruction , in connection with safety and access for
service and maintenance. See the drawings in this
chapter. Pay particular attention to any flammable
materials. Please take into account the possibility to
open the door of the heater for the necessary service
and maintenance work . Make sure the air flow to
and from the heater is unhindered. Any obstacles
should be a minimum of 5 metres away from the
front of the heater.
•When the heater is installed other than horizontal,
Always re-adjust the CO2 setting from the gas valve.
•The heaters are provided with M10 threaded
sockets as fixing points (see the dimension
diagram).
•Use preferably the Winterwarm suspension kits.
•Make sure that after fitting, there is no mechanical tension on any connecting gas or electric
supplies.
•If the heater is installed with the air stream vertical downwards the maximum suspension
height is 8 meters. Otherwise the warm air will not reach the floor.
Attention:
See the application-restrictions in this manual (Chapter 2) for further installation restrictions.

4.3 Gas connection
The gas supply line has to meet the national valid requirements and possibly the local
requirements of the building inspector, police or fire brigade. (In GB it must comply with Gas
Engineers publication UP-1 and UP-2 together with BS 6891.
A manual isolation valve in the supply line must be placed within reach of the heater, and all gas
lines must be mounted without any mechanical tension.
When testing the supply lines with pressures above 60 mbar, this manual valve at the heater
must be closed.
The working and standing supply pressure must be a minimum of 17 mbar, and a maximum of
30 mbar ,measured at the inlet pressure nipple of the gas control in the heater
In case the heater needs to be converted to another gas type contact your supplier. It can only
be converted by the manufacturer or its representative.
4.4 Electrical connection
4.4.1 230Vac supply
The installation must comply with local and
national requirements, ( as well as IEE
regulations)
Never use a room thermostat to interrupt the
electrical supply to the heater!
Make provisions to completely isolate the heater for maintenance purposes. This can be an
isolation switch (min.3mm contact opening gap) , a power plug or a non-switched fuse spur.
The wiring diagram for the heater can be found towards the end this manual.
The supply is 230Vac. with earth. The control circuit is a two wire low voltage bus
communication.
4.4.2 Room thermostat

ON/OFF thermostat
The heater cannot be controlled with a simple on/off thermostat.
In all cases the communication between heater and thermostat is based on a two wire, low-
voltage connection. In the appliance the wire for the thermostat has to be connected to
connection 4 and 5 (see also electrical wiring diagram) Attention: This also needs a change in
the settings on the print board.
4.4.3 Thermostat installation
When mounting the thermostat, take attention to the following items:
•Mount the thermostat in a place where the air can circulate free pass the thermostat. Take
notice that the sun does not shine directly upon the thermostat (in the winter). Do not
place the thermostat on a cold wall. Place the thermostat on an inner wall free from
draught.
•Never place the thermostat within the throw of the heater.
•Never mount the thermostat near aerials of internal communication networks. These emit
radiation that could lead to disturbance of the thermostat. Always keep some meters
distance.
•In all cases the communication between the heater and the thermostat is based on a two
wire, low-voltage connection. In the appliance the wire for the thermostat has to be
connected to connection 4 and 5 (see also electrical wiring diagram).
Cable specification: signal cable, 1x2x0,8 (shielded and twisted)
Maximum length 250m.
If the cable is chosen too thin, the signal will become too poor. If the cable is not shielded and
twisted the signal might become disturbed in an EMC unfriendly environment.
Keep the thermostat cable separated from mains cables. Connect the earth shield of the cable
only to the earth terminal in the heater.
If these guidelines are not followed it may result in malfunction of the installation or worse, it
could damage the thermostat or the electronics in the heater.
4.4.4 Fuse
On the heater control board there is 1 fuse. See electrical wiring diagram.
F1 and in the power supply of the heater. Replace the fuse only by a fuse of the same type, 5AT
4.5 Air intake / combustion products discharge
Check for compliance with local / national regulations.
Only the described flue material may be used. This goes for the roof or wall terminal and also
for the piping between the heater and the terminal. Only so the installation is approved.
Do not use terminals for condensing appliances. This can lead to water inside the flue system.
In some cases the roof terminal has to be at least 0,5m above roof level (depending on local
regulations).
Pay attention on fresh air ventilation openings on the building. There are local distance
restrictions on placing a flue terminal near the ventilation openings.
4.5.1 Flue material
It is only allowed to use CE marked flue material from the manufacturer Muelink & Grol (M&G)
and Burgerhout, type Alu-fix temperature class minimum T200. These Flue systems can be
bought at your supplier.
Only use one flue pipes from the same diameter as the flue spigots on the heater.
Different manufacturers have different connections systems from the flue pipes. It is not allowed
to combine systems from different manufacturers.

4.5.2 Maximum flue length
Vertical: 9 meters is the maximum length between the heater and its flue outlet.
Horizontal: 6 meters is the maximum length between the heater and the flue outlet.
When bends are used, the pressure drop will increase and therefore a 90°bend will count as 2
meters and a 45°bend as 1 meter. For further information regarding the flue system, please
contact your supplier.
4.5.3 Flue terminals
The following flue terminals are allowed:
Vertical discharge Horizontal discharge
TR10-28: DDV 80/125 art.nr. IA8202 CT 80/125 art.nr. IA8113
For h>0,5m above roof IA8218

4.5.4 Condensation in the discharge system
During heating up, it is possible that condensation is formed in the discharge system. This
however, will evaporate if the heater is operating for a longer period of time.
If the straight length of the discharge flue is longer than 4 meters this condensation will not
evaporate again and accumulate in the heater! Isolation of the discharge pipes or a
condensation trap just at the heater is then absolutely necessary.

7
T-piece (6) condensate trap (7) condensate drain
Ø80 art.: IA8223 IA8225 IA8286
Ø100 art.: IA8176 IA8188 IA8288
This condensate will most likely not be formed on heaters more than 20kW.

Instructions condensing Air heaters type XR version XR-GB-4001-a Page 13/27
On the smaller heaters like the TR10 and TR15 the forming of condensate is a risk.
When a heater often burns, and is placed in a normal heated room (temperature above 15
degrees) the condensate risk is low.
When a heater is placed in a room that only needs to be just above 5 degrees, it will only burn
for a very short time. In this short time the condensate that is formed will not evaporate. And the
condensate accumulates and will eventually result in pressure switch errors.
In general, when the flue pipe is long and is running through a cold space condensate can be
formed.

The distance between the brackets should be spread out equally.
•Inside a shaft:
Check the components on possible damages or blockage..
Check that the pipe is under the right inclination.
Mark the flue pipes and fresh air pipes to avoid a mistake.
Check that the pipes extend minimum 50mm when going through a wall or other obstacle.
Fix the last element before entering the shaft. If this is an elbow, also the 2nd element
may be fixed.
•ATENTION, every system needs to have at least 1 bracket. The first bracket needs to be within
the first 0,5m from the appliance..
5Functioning of the unit
5.1 General
The unit can heat as well as ventilate. By using the temperature-sensor on the unit and the one
in the room-thermostat, the temperature-difference between the two in the room is monitored.
Should the difference become higher than a set value, due to the fact that warm air has
accumulated underneath the roof, the system-fan will start and push the warm air down, acting
as a de-stratification fan.

Minimum burn time 4 minutes!
The heater will always burn minimum 4 minutes, even if the heat demand stops. This to avoid
an unnecessary large amount of start and stops.
The heater will try 2 times to ignite before it stops and gives an error.
5.3 Delta-T-regulation (temperature controlled de-stratification fan)
In case there is no heat demand, the delta-T-regulation will be active.
When the temperature-difference between the sensor on the unit (the NTC) and the sensor in
the thermostat is bigger than the set value (factory setting standard 8°C), the system fan will
start, at a regulated speed, depending on the differential temperature difference. This operation

Instructions condensing Air heaters type XR version XR-GB-4001-a Page 16/27
ensures an even temperature distribution throughout the building, thus acting as a fully
automatic variable de-stratification fan.
Switch of delta-T-regulation
Should this delta-T-regulation not be required, in the Menu Program Settings on the room
thermostat this regulation can be switched off. See user manual of the special Winterwarm
Room thermostat.
5.4 Summer ventilation
It is possible to let the ventilator run on a certain speed in the summer. Please follow the
instructions in the manual from the thermostat.
5.5 High limit protection
5.5.1 T max. Heat exchanger
The unit contains 2 temperature protections. The NTC thermostat monitors the air temperature
electronically. Should the temperature, as a first step, become too high, the burner will modulate
to the minimum input and the system fan will modulate to the maximum speed.
When the temperature still increases, the burner will switch off. The display will show E05 / E36.
When the heat exchanger has been cooled to normal levels the burner will start automatically.
Should the temperature increase to an unacceptable level, the heater stops. The display will
show L31. Only after a manual reset the heater can start again. Manual reset can be done on
the electronic circuit board or with the special Winterwarm Room thermostat
5.6 Flue Transport Supervision
The unit is provided with a pressure switch to control the transport of combustion air through the
heat exchanger. It checks in the pre purge phase if there is sufficient movement of combustion
air through the heat exchanger. If the pressure difference is too low in the pre purge phase, the
fault L14 will occur..
6 Putting into operation and adjustment
6.1 General
Prior to packaging, each unit is checked in detail on safety and functioning. It is adjusted to the
right efficiency of combustion. In general, the heater does not need to be adjusted after
installation, only a check of functioning is necessary. Also obtain a flue gas analysis and record
it for later reference.
Use only calibrated instruments !
The burner pressures only need adjusted if the pressure differs more than 0,5 mbar from its
setting. Do not ever turn injudiciously the adjusting screws!
Adjustment of the gas control without a supporting flue gas analysis will invalidate the warranty.
Once the unit is installed according this manual, the unit can be put into operation. Make sure
the gas pipe is clean, gastight and free from air.
Switch on the electric supply with the maintenance-switch, and open the door in order to be able
to observe the first start-up and so become familiar with the functioning of the heater.
Should the gas line not be purged correctly the heater will attempt to start twice before going
into a lock-out condition. Manual reset is necessary in that case.
Do not forget to instruct the end user about a safe use of the heater (presence of gas, place of
the manual gas valve !), the operation of the heater (lock-out indication and reset) and about the
necessary maintenance. This manual must be left with the end user.
6.2 Start by using the thermostat
Put the thermostat in the highest position. The start sequence is always the same
NOTE:The heater will always burn for minimum 4 minutes before it switches off.

Instructions condensing Air heaters type XR version XR-GB-4001-a Page 17/27
6.3 Start through the display in the heater
The manual test mode trough the display in the heater will only work for maximum 10 minutes.
1.Pres and hold the Return and – button for a few seconds. The display will show Lo / St
intermediate.
2.The heater will start up in Low fire.
3.Toggle between Low and High fire by pressing the + and – button,
4.Exit the service menu by pressing the – button until 0 is displayed.
5.The heater will always cool down the heat exchanger for a few minutes.
6.After 10 minutes the test mode will automatically end.
.
7Adjusting the gas-control
In principle, it is not necessary to adjust the gas control after putting the unit into operation.
In case it needs to be adjusted, (e.g. after fitting a new one), this must be done only by a
qualified person. Only use calibrated instruments! A poor adjustment can lead to
overheating and / or production of toxic carbon monoxide!
The burner pressures can be adjusted as follows:
- Remove the cover from the gascontrol with the help of a (small) screwdriver.
-Start the unit and first set the high burner pressure by turning screw (external 10mm).
The High / low coil must be energised !
-De-energise coil (disconnect wire) and set low burner pressure by turning screw (slot for
screwdriver) Do not set lower than 3 mbar in order to avoid problems with inter-lightning of
burnerstrips.
TR10 up to 50 TR60 up to 125
Attention: Always check each burner pressure after any adjustment, as they influence each
other.

Always check the CO production of the
heater!!! Too much CO usually means the
mixture is too rich. Adjust this if necessary
with the two adjusters (see above)
The TR125 and TR150 are provided with two
gas control valves. The adjustment of the
high and low burner pressure setting is in
principle equal like the above described
adjustment of the burner pressures. The
burner pressures for high and low should be
measured and set at each gas control valve
itself. After the adjustment of the burner
pressure the burner pressure should be
checked on each gas control valve.
The TR150 heater is provided with two
Honeywell Gas control valves. TR150
Never forget to check the CO (carbon monoxide ) production of the heater!!! Too much CO
means mostly that the mixture is too rich. CO value should always be below 100 ppm.
8 Problem solving
8.1 General
When it turns out that the problem is not caused by the external circumstances (i.e. no electric
supply power or no gas), please take the following instructions into account. Please remember
the built in waiting times of the heater (do not react too soon!) and the signals of the LEDs and
the code on the display on the electronic circuit board.

Case 1: Within 5 sec flame, then flame failure.
•The flame is not detected. Check the ignition cable and electrode. (cable resistance 1k
Ohm).
•The electrical earth of the heater is poor,
•The print board is defective.
Case 2:
•There is not enough gas pressure.
•The mixture of gas/air is poor, adjust the gas valve
•The gas valve does not open, check during ignition for 230V on the valve.
•Check whether the ignition electrode sparks, replace cable, electrode
Case 3: Heat exchanger too hot
•Check whether the system fan blows enough air.
•Check the setting of the gas valve, the heater may me overloaded.
Case 4: Temperature sensor on heat exchanger error.
•The sensor has internally 2 sensors. These differ too much. Measure the resistance
from each sensor, the resistance should be 20K at 25°en 25K at 20°. If the measured
values differ too much, replace sensor.
•L-25 is heat exchanger sensor, L-26 is flue sensor
Case 5: Too many flame failures while burning
•The setting of the gas valve is not ok, adjust the gas valve
•The flue outlet is blocked

Instructions condensing Air heaters type XR version XR-GB-4001-a Page 20/27
Case 6: The premix does not run
•Premix fan is Blocked or the wiring is bad
•Premix fan is defective
Case 7: The pre-mix fan runs, but not the correct speed.
•Check if the fan runs smoothly.
•Check the wiring.
Case 9: Reset button error
•Too many switches on reset button in a short period of time. These error will disappear
after some time, or if the main power is disconnected for a while.
Case 10: Safety relay error
•Plug J2 is not connected well, the bridge on connector J2 between 1 and 4 is not
connected well.
•Otherwise change print board.
Case 11: Insufficient air transport over the heat exchanger
•Check the pressure switch and the connections
•Check the heat exchanger for flue leakage
Case 12: E-fault is 24 hours present.
•An E fault should disappear after a while. When this error is present longer than 24 hr,
something is wrong. Check the error code after a new power up.
Case 13: Internal error.
•Power up the heater again, else replace the print board.
Case 14: Pressure switch closed during stand by.
•When the heater is in standby, the pressure switch should be in the rest position. When
it is in the closed position the contact could be stick, or water could be in the small
hose.
•Replace the switch or dry the hose.
Case 15: Flame detected after closing of the gas valve.
•The gas valve closes too slow, replace the gas valve
•The ionisation electrode is wet. Dry or clean the electrode. Or change the electrode.
Case 16: Flame detected before opening the gas valve.
•Check it there is really a flame before ignition, if that is the case, replace the gas valve
•The ionisation electrode is wet. Dry or clean the electrode. Or change the electrode.
Heater does start, but shows other problems:
Heater ignites explosively, has often flame failures:
•Check the right setting of the gas control, the right CO
2
setting is important for the
correct ignition.
•Check the ignition cable (1kOhm )
•Check the setting of the ignition electrode, the spark has to be formed between the
electrodes and not between the electrode and the burner.
Insufficient output
•The heat output of the heater will be insufficient if there is too much resistance in the
inlet- or outlet flue system. In this case the premix-burner-fan will be on full speed, but
because of the high resistance too little air is moved and therefore also too little gas.
The pressure in the outlet flue for example, will normally never be above 30 Pascal.
Non modulating system fan
•System fan (M1) does not start or does not vary in speed; Check first the functioning of
this fan by connecting it to 230 Volts. Check with a multi-meter if the different lower
tensions are secondary present on the transformer as well. The fuse could have failed.
If the motor and transformer are OK, the cause of the problem must be in the heater
control, as the heater control dictates the different voltages from the transformer to the
fan-motor. In that case, replace the heater control.
