Positioning
The radiant tube can be mounted with
chains [links min. 4 mm]
adjustable steel wire suspension system
[Schwank accessories]
If you chose chains please use bolts with lock nuts
for fixing the chain to the suspension bracket.
The radiant tube has to be fixed by
vertical chains etc. to the roof or to
supporting devices.
Chains and steel cables have to be fixed
in vertical direction or slightly diagonally
outwards above the fixing points of the
suspension brackets to the roof or to
supporting devices. Fixing of the
suspension cables or chains diagonally
inwards to the centre of the heater is not
permitted [see Fig 5].
Please note that the radiant tube being
in operation expands several
centimetres because of thermal
expansion. Avoid therefore inflexible
suspension.
Do not use fixing elements like open
hooks etc.
Hang the heater in balance. We recommend the
use of turnbuckles or adjustable steel cable grips
for ease of adjustment and balance.
Fixing points for chains or steel cables on the heater
are shown in Fig. 15 and 16 on pages 20 and 21.
Attention!
If you do not align the burner kit
correctly material damage and
destruction of the heater may occur.
Fig. 5: Chains and steel wire mounting
Fig. 6: Slope of radiant tube heater
SCHWANK GmbH will not accept liability
for damages caused by incorrect
mounting of the burner unit. Correct
mounting is the responsibility of the
installer.
Attention!
Make sure that the heater has in
longitudinal direction a slight slope
[3 mm per meter] to the turnaround box
[Fig. 6].

Air supply / Exhaust Requirements
The calculation of air supply / exhaust
requirements of a building heated by radiant tube
heaters is subject of European Directive EN 13410.
Please follow local by-laws as well.
Please see the max. lengths of combustion air
supply- and exhaust flue pipe on page 9 [Tab 3,
point 3].
Place of Installation
The room to be heated must have an air volume of
minimum 10 m³ for each kW of the nominal
thermal load of the installed heater.
Air supply [combustion air from inside the
room, types A3 and B23]
Heating installations with combustion air from
inside the room are only allowed in rooms without
string air pollution. Otherwise use system with
combustion air from outside [type C].
In halls and buildings with a normal air change by
means of joints and gaps it is not necessary to
install additional equipment to ensure combustion
air supply.
Air supply / exhaust systems
For the radiant tube infraSchwank D / calor
SchwankD the following air supply / exhaust
systems are possible:
1. Indirect flue into the room
[Type A3 without exhaust system,
combustion air from inside the room]
2. Flued with individual exhaust system,
combustion air from inside the room
[Type B23]
3. Flued with individual exhaust system,
combustion air from outside the room
[Type C]
4. Flued with flue collecting system and
central flue fan – combustion air either from
inside or from outside [according to EN 777,
Type F]
1. Indirect flue into the room
[Type A3 without exhaust system combustion
air from inside the room]
The exhaust air of the tube heater has to be
conducted from the inside of the room to the
outside.
Conduction of the exhaust air may be carried out
with one of the following 3 methods:
a) Thermal ventilation: Combustion air and
exhaust air are to be conducted through
fixed outlets positioned on the roof or on
the walls of the building.
b) Mechanical ventilation: Combustion air and
exhaust air are to be conducted through
one or more fans positioned on the roof or
on the walls of the building.
c) Natural ventilation: Combustion air and
exhaust air are to be conducted through
outlets as a result of differences in pressure
and in temperature between the internal
and external side of a building.
For exact dimensioning and positioning
of supply air and exhaust air outlet of the
building according to EN 13410 or
G 638-2 please contact Schwank GmbH,
phone +49 [0] 221 / 7176 0.


infraSchwank D / calorSchwank D shape U
10
Version 021 infra D Form_U 16/19 _INT Technical specification subject to change
2. Exhaust flue with individual exhaust system -
combustion air from inside the room
[Type B23]
Only use this system in rooms with no air pollution
and without relevant pressure differences to
outside. Otherwise use type C.
3. Exhaust flue with individual exhaust system -
combustion air from outside the room
[Type C]
Combustion air and exhaust air are to be
conducted by a temperature stable, concentric
pipe from a wall or roof entrance.
Max. length of the concentric pipe can be 6 m
plus two 90° elbows.
The concentric pipe ends at a bifurcated pipe.
Please ensure that theconnection for exhaust air
between heater and bifurcated pipe is a flexible
pipe. Do not use back-pressure valves or dampers
in the exhaust flue.
Tab. 3: air/exhaust routing
Fig. 7: Air/exhaust-system,
version aluminium or stainless steel
4. Exhaust flue with flue collecting system and
central flue fan
[according to EN 777, Type F]
The heating installation must not exceed 10 radiant
tubes. The exhaust air of each tube is collected
via a central collecting tube system by a central
flue fan and led to the chimney. Planning,
construction and layout of such installations must
be carried out by Schwank employees, as well as
commissioning. The strict observance of the
Schwank layout-drawings and calculation figures
are the precondition of the manufacturer’s
warranty.
With system F the radiant heaters will be installed
with their individual flue fans. Please note that it
necessary to install in the collecting pipe behind
each radiant heater and in the following collection
pipes damper or a pressure-balancing device. This
ensures a precise regulation and an even exhaust
flue of each radiant tube.
For detailed information regarding
setting up and commissioning of a flue
collection system please see

6 Operation
The installation must be carried out by
a qualified engineer following the
manufacturer’s instructions.
SCHWANK will not accept liability damages
caused by improper assembly and/ or operating
of the heater. Proper assembly and operation is
the responsibility of the user.
Switching on the heater
First switch on the central control unit
SchwankControl Touch and activate a
heating command.
After a pre-purge period of about 25 sec.
the ignition starts.
Switching off the heater
Disable the heating command on central
control unit SchwankControl Touch.
If the radiant tube is controlled by a thermostat
the heater will be switched on and off
automatically.
Fault
If no flame is reported during the pre-purge
period and the safety time [approx. 30 sec.] the
heater repeats the ignition process. If there is no
flame after the second ignition process the
heater switches off automatically and is locked.
Investigation and repair must be carried
out by authorized personnel. After
clearance of the fault the heater can be
reset.
The cause of the fault / error code is
displayed on the central control unit
SchwankControl Touch or can read out via
corresponding service software IC 4000.
See chapter 12 for error codes.
Lock release [Reset]
Activate the reset command via the
central control unit or interrupt the electric
power supply for 3 seconds.
Maintenance
Servicing of the heater is essential for continued
efficient operation. Servicing should be carried
out not less than once a year by a qualified
service engineer. After any servicing, the heater
must be recommissioned as detailed in
Chapter 12.
