1. APPLICATION RESTRICTIONS
The installation and maintenance of this air heater should be performed by an authorized
competent installer and in accordance with this manual.
The appliance shall be CE marked.
Respect the safety clearances with the inflammable materials.
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless they
have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety. Children should be supervised to ensure that they do not play
with the appliance.
In case where the air intake is done inside the room (type B connection), provide a
sufficient ventilation by referring to the rules in force.
1.1 Pre-check
Before unpacking and installation, please check (i.e. on the data badge) if the heater is in accordance with
the order and if it is suitable for the local present provisions (gas type, gas pressure, electrical supply etc.)
The Installation must comply with all applicable local and national standards.
If this heater is drawing its combustion air from within the room in where it is located, the necessary
combustion ventilation requirements must be followed for gas safety regulations.
Make sure that the warm air can be blown out freely. There should absolutely be (no possibility of)
materials within 5m from the front of the heater.
The heaters have been tested in detail on safety and correct operating settings before leaving the factory. It
has been adjusted for the type of gas that is stated on the data badge.
If there is any doubt, please contact SBM.
1.2 Protection degree
The appliances have been designed for a use in a dry and not very dusty environment (protection degree
IP20).
The heater should not be installed in areas containing any corrosive or explosive steam, in high moisture or
dust concentrations, at negative pressures or temperatures higher than 30°C; please consult SBM. The
guarantee is then invalidated.

The AMC 78, 97 and 116 models are compound respectively of 2x AMC 39, 2x AMC 48 and 2x AMC 58
in a same body with one gas connection and one air intake/exhaust gases, one electric connection, one
connection for the thermostat and one connection for condensates.
For a proper operation and in order to avoid interaction between the premix fan and the burner, a check
valve was added.
The connection of the MULTITHERM C or S to the AMC 78, 97 and 116 models as well as the micro-
switch S2 and S3 setting is explained in the paragraph 9.3 and 9.4, pages 22 and 23.

3. INSTALLATION
3.1 Hanging and fixing
 Check that the support is solid enough.
 The warm air heater must apire and exhaust freely
The presence of any obstacle can conduct to an over-
Heating of the appliance.
 Keep sufficient distance between the heater and any
obstruction, in connection with safety and access for
service and maintenance. 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.
 The heater can be installed horizontally or with an angle of maximum 45°.
• The units are provided with pieces of M10 threaded sockets as fixing points.
• AMC 12 and 19 models have 2 pieces of M10 threaded sockets in their centre on the top and
underneath the heater.
• AMC 29 and 39 have 2 pieces of M10 threaded sockets in their centre on the top and underneath
then 4 additional pieces of M10 threaded sockets on the top of the heater.
• AMC 48 and 58 models have 4 threaded sockets on the top and underneath.
• See the schemes above to see the dimensions.
• We recommend using the SBM suspension kits for a safe installation.
• Be sure that there is no mechanical tension on the different connections after installation.
Consult the “APPLICATION RESTRICTION” chapter page 4.

3.2 Gas connection
 The gas installation shall be done by a qualified worker. The rules of gas installation shall be
respected.
 A manual isolation gas valve in the supply line must be placed within reach of the heater, and all
gas lines must be mounted without any mechanical tension. The installation of a gas filter and the
purge of gas pipes before the first start-up are strongly recommended.
 The sealing of the gas network have to be checked before the first start of the installation according
to the rules in force.
 The dynamic gas pressure upstream the solenoid valve shall be at least 17 mbar for G20 and
20 mbar for G25. This dynamic pressure cannot be greater than 30 mbar.
For G31, it shall be less than 37 mbar.
 It is eventually possible to change the gaz type (natural gas/propane).
In this case, please contact your installer.
These appliances were design to operate with natural gas G20 or G25.
When operating with G25, the heat input will be lower than when operating in G20 (see the
technical specifications in page 5).
It is forbidden to turn the setting screws which are sealed by the manufacturer.
3.3 Electrical connection
3.3.1 Electric supply 230 V
 The electrical installation shall satisfy the local/national rules in force. Be sure that the main supply
is 230VAC with earth and a R.S.D (Residual Current Device) with a sensibility of 30 mA
upstream the heater for the protection of people and installation. The polarity phase/neutral shall be
absolutely respected.
See the electrical diagram, pages 24 and 25.
3.3.2 Electrical supply interruption
 Never interrupt the power supply of the device accidentally. It could drive to an overheating of the
heat exchanger and to the safety state of the overheated device.
Be careful to the electric breaks of the network, it is possible that the temperature of the appliance
is going up (overheating)
Never turn off the power while the unit is warming up!
3.3.3 Room Thermostat
 The warm air heaters AM can be driven only with the MULTITHERM S or C thermostat.
They are not operating with simple ON/OFF thermostat.
 MULTITHERM thermostats type :
MULTITHERM S (Ref SBM 5760001) ; modulating numerical thermostat
without clock able to regulate from 1 to 8 appliances AMC 12 to 58 or 1 to 4 appliances
AMC 78 to 116.
MULTITHERM S WITH CONTACT (Ref SBM 5760004); modulating numerical thermostat
without clock, with terminal for external contact, able to regulate from 1 to 8 appliances
AMC 12 to 58 or 1 to 4 appliances AMC 78 to 116.
MULTITHERM C (Ref SBM 5760001) ; modulating numerical thermostat with clock able to
regulate from 1 to 8 appliances AMC 12 to 58 or 1 to 4 appliances AMC 78 to 116.
MULTITHERM C WITH CONTACT (Ref SBM 5760005) ; modulating numerical thermostat with
clock, with terminal for external contact, able to regulate from 1 to 8 appliances AMC 12 to 58
or 1 to 4 appliances AMC 78 to 116.

10
 Recommendations for MULTITHERM installation :
• The connection between the MULTITHERM and the warm air heaters have to be done with
a two-wires shielded and twisted cable 1 x 2 x 0.75 mm, with a maximum length of 200 m.
• Connect the earth shield of the cable only to the earth terminal in the warm air heater.
• The appliances should be disconnected from the electrical network during the connection.
• The installation and start-up of the room thermostat are described into the technical instructions
delivered with the MULTITHERM S or C.
• The thermostat have to be installed in a dry place and moderately dusty.
• Place the thermostat in a place where the air can circulate freely.
• Take care of the risk of sun exposition or the presence of warm sources.
• Avoid installing it near to a cold wall or where there is air flow.
Do never install the thermostat closed to the internal network communication antennas!
These last are emitting a radiation which can conduct to a disturbance of the thermostat.
It is always necessary to keep a distance of some meters.
3.3.4 Fuses
 There are 2 fuses in the appliance, on the main print board: F1 and F2 are placed on the phase
and neutral of the electric supply of the heater. In case of defective fuse, replace it with an
identical fuse size 5x20 - 5A Temporized.
3.4 Air intake / combustion products discharge
Check for compliance with local / national regulations. Only the material mentioned above can be
used. This applies for wall or roof terminals also for exhaust products connections in order to have a
certified and approved installation.
In some cases, and according to the regulation, the terminal must exceed the rooftop by at least 0.5m.
3.4.1 Flue materials
 It is allowed to use only the sealed and corrosion resistant flue pipes CE marked with a
temperature class at least T120.
These flue pipes are not supplied by SBM.
Use only flue pipes with the same diameter.
3.4.2 Terminals
 Only the terminals supplied by SBM can be used.
These terminals are certified with the warm air heaters.
