Introduction
The instructions for the installation, operation and control refer
to the products of Systemair - the re air grille intended for
ventilation openings in walls without ductwork.
This manual contains basic information and recommendations
regarding the installation, use and inspections that need to be
followed to ensure the proper and smooth operation of the FGS.
The Systemair FGS is passive in terms of the amount of noise
generated. There is increased noise only when closing or opening
the FGS in cases of inspection or re accidents (only lasting for a
maximum of 60 seconds).
Warnings
Some FGS parts can have sharp edges – therefore it is necessary
to use gloves during FGS installation and manipulation.
In order to prevent an electrical injury, re or any other damage
which could result from incorrect FGS manipulation, installation,
usage and operation, it is important to:
1. Install the FGS in accordance with this installation manual and
by a properly trained employee.
2. Execute FGS inspection in accordance with this installation,
operation and maintenance manual.
3. Before you can install the FGS, it‘s functionality must be
checked according to Chapter 3 (“Functionality check“).
This procedure prevents the installation of an FGS that has been
damaged during transport or handling.
DO NOT INSTALL A NON-FUNCTIONING FGS!
Operating conditions
• Maximum air ow velocity 12 m/s (ventilation openings
in the wall without ductwork)
• Temperature within the range -20 °C up to +50 °C
• The active re-proof sealing must not be exposed to direct
contact with water.
• Purging air is only allowed without mechanical or chemical
contamination, with a uniform ow and without condensation,
ice coating or ice.
• FGS grilles are designed to be used in vertical supporting
constructions.
The device closes when the ambient temperature reaches
74 °C (manual FGS) or 72 °C (motorised FGS). In the event of
having to adjust for higher temperatures in the workplace, it
is necessary to consult such demands with the producer and
indicate them in the purchase order accordingly.
1 Installation
The installation must be done as follows:
• The FGS must not bear any part of the supporting construction.
This could lead to damage and the subsequent failure of the FGS.
• The distance between the FGS and building structures,
distribution technology and ventilation equipment must be
large enough for the reliable performance of the installation,
functional testing, inspection and repair.
• The distance between the FGSs must be at least 200 mm
in a solid wall according to EN 1634-1.
• The distance between the FGS and the wall must be at least
250 mm according to EN 1634-1.
• The FGS must be installed along the horizontal blade axis.
• Before the installation of the FGS, its functionality must be
tested according to Chapter 3 (“Functionality check“).
DO NOT INSTALL A NON-FUNCTIONING FGS!
• Changes to the functionality of the FGS, caused by transport
or installation, aren´t reclaimable after the installation
(deformations, damages, mechanical damage of the sealing
material, foreign objects which can constrain the blades,
improper handling of the activating mechanism, etc.)
• During installation it is necessary to protect the FGS mechanism
and its interior against dirt. The blades must be in the closed
position. This is necessary to avoid the deformation of the FGS.
• The FGS must be installed according to Fig. 2 or 3.
• After installing the FGS, it is necessary to connect the electrical
installation which must be only done by authorised persons the connection must be done according to Fig. 4 - 8.
• The actuators have two microswitches indicating the open and
closed positions of the blade - see Fig. 5 - 8.
• The setup, install, repair, overhaul and inspections of the FGS
must only be done by trained personnel.
1.1 WET installation of the FGS into a solid wall using a plaster
mixture, mortar or concrete (Fig. 2, Tab. 2)
1. Prepare a rectangular opening with dimensions
L
1
= L + 260 mm and H1 = H + 135 mm (according to Fig. 1),
the opening surfaces must be even and cleaned.
2. Put together the frame from two parts (1a a 1b) according to
the wall width, and screw it into place with screws DIN 7982
C-H 4.2 × 13 included in the pack.
3. Fix the frame to the rectangular opening with screws
(recommended screws 5 × 100, fabory 29385.050.100,
screws not included in pack) Fig. 2. Part 1a of frame has to
be abreast with the wall. Lead the cable for the connect
- see Fig. 10 and 11.
4. Fill the space between the frame and the rectangular opening
with the plaster mixture, mortar or concrete (Fig. 2).
5. Connect the connector with the plug.
6. Insert the closed FGS into the installation frame, join the
connectors and x both the upper and lower sides of the FGS
with screws DIN 7504M-SR 4.2 × 25 (Pos. 6; screws are in
the pack - the amount depends on nominal dimensions of
the FGS)
7. If needed, uncover and clean the FGS after installation.
8. Check the functionality of the FGS.
Before putting the FGS into service after installation (and
in subsequent periodic inspections) a visual inspection and
functionality test must be conducted. After the visual inspection
and functionality test the results must be recorded in the
Operating log (page 13).

1.2 Installation of the FGS into a SOFT CROSSING (Fig. 3, Tab. 2)
1. Prepare a rectangular opening with dimensions L1 = L + 260
mm and H
1
= H + 135 mm (according to Fig. 1), the opening
surfaces must be even and cleaned.
2. Put together the frame from two parts (1a a 1b) according to
the wall width, and screw it into place with screws DIN 7982
C-H 4.2 × 13 included in the pack.
3. Prepare the mineral wool installation segments (with density
150 kg/m
3
, thickness 50 mm). First apply the suitable
reproof layer/glue (e.g. Isover BSF) onto the FGS installation
frame at the place of its future placement, assemble and glue
the lling of the future installation with the same glue.
4. Fix the frame to the rectangular opening with screws
(recommended screws 5 × 100, fabory 29385.050.100;
screws not included in pack; Fig. 3). Part 1a of frame has to
be abreast with the wall. Lead the cable for the connect - see
Fig. 10 and 11. After the glue has dried, the installation frame
along with the lling are ready for installation.
5. Apply the same glue onto the internal surface of the wall
opening. Also apply the same glue on the external surface
of the lling glued on the damper surface. Immediately after
application, place the installation frame into the wall opening
in such way that will not deform the installation frame.
6. After inserting the installation frame into the opening and
after xing it, apply the same re-resistive mastic, at least
2 mm thick layer and 100 mm wide, on the opening lling
and wall edges evenly from both sides.

12. Check the functionality of the FGS.
2 Operation and maintenance
2.1 FGS operation
After installation, the functionality of the FGS must be checked
and set into the open operating position.
2.1.1 Manual FGS
On the bottom of the front right side, one hole is placed (Fig.
12). Insert a screwdriver through this hole or a thin object with
a diameter of 6 mm max, lever up the upper blade and push
the latch (spring) - this releases the mechanism. Twist the
blades into the horizontal position (in the direction indicated
by the arrow - Fig. 13), force against the spring and x the rst
blade from the top side with the thermal fusible link (Fig. 14).
2.1.2 Motorised FGS
By connecting a power source according to the relevant
scheme displayed in Fig. 5-8, activate the actuator and the
blades will open. For an actuator with the BKN230-24 unit by connecting a power source to the unit BKN230-24, activate
the actuator and the blades will open.
2.2 Maintenance
Systemair FGSs are maintenance free. Only periodic dry cleaning
is necessary - no different than entire ventilation systems.
3 Functionality check
3.1 Manual FGS
In the open position, all blades must be fully open and detented,
and the appropriate signaling circuit must be switched on.
• To close the FGS: lever up the upper blade with your ngers
and release the thermal fusible link by pushing with a
screwdriver in the direction indicated by the arrow (Fig. 15).
Remove the screwdriver and release your ngers from the
blade. The blades must come up to the fully closed position
and remain there detented.
• After reaching the end position of the blades, the appropriate
signaling circuit must switch on.
After checking, set the FGS into the open position (that is the
operating position; see Chap. 2.1.1).
3.2 Motorised FGS
After connecting the supply connectors (see Fig. 10 and Chapter
2.1.2), the FGS opens.
• The blades must come to the fully open position and must
remain there detented.
• After reaching the end position of the blade, the appropriate
signaling circuit must be switched on.
After disconnecting the supply connector (see Fig. 10) - e.g. by
means of pulling the FGS out of the frame - the FGS closes.
DO NOT COME IN CONTACT WITH THE BLADES DURING THEIR
MOVEMENT TO AVOID RISK OF INJURY!
• The blades must come up to the fully closed position and
remain there detented.
• After reaching the end position of the blades, the appropriate
signaling circuit must be switched on.
After checking, set the FGS into the open position (that is the
operating position; see Chap. 2.1.2).

4 Inspection of the FGS
Each FGS should be inspected immediately after installation, as
well as every 12 months, based on the following steps:
1. Identication of the FGS
2. Date of inspection
3. Check the electrical connection of the activation mechanism
4. Check the electrical connection of the end switches
5. Check the FGS for cleanliness, and eventual treatment (when
necessary)
6. Remove the protective grating.
7. Check the tightness of the blades, and record their eventual
correction (when applicable)
8. Check the Intumex and rubber sealings, and record their
eventual correction (when applicable)
9. Check the safety FGS closure - for details see Chap. 3
10. Check the FGS functionality (for details see Chap. 3) with
regard to opening and closing the control system, tracking
the physical behaviour of the FGS and the signalisation of
the end positions, and record their eventual correction (when
applicable)
11. Set into the operating position - see Chap. 2.1
12. Assemble the protective grating.
13. Record into Operating log (page 13) with the name and
signature of the technician.
The FGS is usually part of a system. In this case the system must
be checked as specied in its operational and maintenance
requirements – this is a task for the installer of the entire system.
