2.4  CONNECTION OF COMBUSTION AIR / INSTALLA-

TION OF S-THERMATIK, MOTOR / AIR BOX

Installation sequence - combustion air connection:

Step 2.4:

Installation occurs in the reverse sequence. During the installation, proper 
opening and closing of the rotating disc must be checked! See point 2.3 on 
page 7 in this regard.

2.5 CHANGING THE DOOR STOP

If the door stop is to be changed, this is also possible after the overall 
system has been completed. For this, a new door must be ordered with 
specification of the order number, which then can be replaced thanks to 
the universal frame.

To remove the door, the following work steps must be executed:
1.  Removal of the „old“ door 
a.)  First, remove the securing clip on the upper pivot hinge.

Step 1.1:

Unscrew the screws in the combustion chamber floor. If the 
combustion chamber lining is already installed, the front sill 
brick and the front floor brick must be removed beforehand.

The floor plate has two notches on the rear, behind which 
a screwdriver can be placed for levering out.

Step 1.2:

To produce the air connection, the four  hexagon socket screws 



 must now be unscrewed. Then the connecting lever 



must be lifted off the air adjustment lever. With this step, the 
entire air control unit is free and can be lifted or taken out 
of the combustion chamber. The combustion air line can now 
be screwed onto the 125 mm or 150 mm ducts below the 
galvanised air box.

Step 2.1:

In order to install or remove the servomotor of the S-Thermatik,
steps 1 and 2 as previously described must be  executed. Then 
the star adapter or the slotted straight pin and the rotating 
disc must be taken out followed by the slide bearing. See also 
Fig. 2, page 8.

Step 2.2:

After removing the air controller parts, the S-Thermatik motor 
is screwed on under the floor of the device.

Step 2.3

:

Then the combustion air connection box must / can be 
screwed back on. If the combustion air should be connected 
on the connection box, the connection cable of the servomotor 
must be inserted through the cable outlet. To reduce input of 
air that cannot be shut-off, this cover must be twisted onto the 
cable as tightly as possible. We recommend that this „damper“ 
is secured with  temperature-resistant adhesive tape.
