Terminal Fire Damper
1 Installation Manual
The terminal fire dampers are installed into the duct, either in the place where the fire-proof wall is, or at the end
•
of the duct in front of an air valve or a similar outlet. (The terminal fir dampers are installed into the duct, either
in the place where the fire-proof wall is into a transversal duct, or at the end of the duct in front of an air valve or
a similar outlet.)
The pitch between the ducts and the fire dampers must be at least 200 mm, according to the EN 1366-2 regulation.
•
According to the EN 1366-2 regulation, there must be at least a 75 mm gap between the wall and the ductwork with
•
the fire damper.
The fire damper is embedded into the fire partition construction pipe in such a way that when the damper blades
•
are in the CLOSE position, they will be entirely situated inside the wall.
The damper can be embedded into a wall or a ceiling with a minimum thickness according to the EN 1366-2
•
regulation for the respective fire resistance class.
All the dampers can be installed with a horizontal or a vertical blade axis.

1.1 Embedding the CF1 - CF2 into a Wall /
Ceiling Using Gypsum, Mortar or Concrete – Wet Installation (see Fig.1)
1. For installation purposes, make a round opening with a minimum diameter of ød + 60 mm into the wall.
2. Insert the duct inside the middle of the opening.
3. Fill in the space between the wall and the pipe with the gypsum, mortar or concrete, while paying special attention
to not contaminate the inside of the pipe.
4. Insert the fire damper into the pipe and ensure that the whole blade of the closed damper is situated within the wall.
5. Check the damper's functionality (see the Operation manual).
1.2 Installation Into the End of a Duct with a Valve (see Fig.2)
CF1 - CF2 can be installed into a wall/ceiling at the end of a duct with a disc valve (the valve needs to be separately
ordered from the ADP catalogue – an advisable type would be the plastic valve "Balance-E" from Systemair AB,
Sweden). The installation is the same as described in section 1.1, remembering that the end of the duct must stay in
allignment with the side of the wall/ceiling where the valve is going to come. When attaching the CF1 - CF2, the area
where its leaves will be inclining after the closure needs to be placed at a distance of 50±10mm from the duct end.
The CF1 - CF2 damper leaves must open in the direction into the duct.
1.3 Embedding the CF1 - CF2 into a Wall Using Mineral Wool –
Dry Installation (see Fig.3 and 4)
1. For installation purposes, make a round opening with a minimum diameter of ød + 60 mm into the wall.
2. Insert the pipe inside the middle of the opening.
3. Attach the cover plates to the wall around one side of the pipe.
4. Fill in the space between the wall and the pipe with mineral wool, while paying special attention to not contaminate
the inside of the pipe.
5. Attach the cover plates to the wall around the other side of the pipe.
6. Insert the fire damper into the pipe and ensure that the whole blade of the closed damper is situated within the wall.
7. Check the damper's functionality (see the Operation manual).
COVER PLATES ARE MANDATORY WHEN PERFORMING A DRY INSTALLATION!
1.4 Adjusting the Damper into Operating Position (see Fig.5)
1. Press both detent springs.
2. Open the blades into a parallel position.
3. Put on the thermal fuse link.
