5.11 Positioning the diaphragm in the fireplace
A diaphragm may have to be installed in the fireplace on flue gas outlet to ensure that the flue pipe configuration
functions properly (see Section 5.3).
To be able to install the diaphragm, the door or the glass insert and the baffle must first be removed.
Now the appropriate diaphragm can be installed.
There is a plate at the top of the combustion chamber in the centre that has two matching slots for installing the
diaphragm. You can install the diaphragm by sliding it in the two slots.

Lip to be folded
The diaphragm must be slid completely into the slots so that the outlet opening is positioned in the centre of the
flue. Next, the lip on the right side of the diaphragm must be unfolded using a screwdriver so that the diaphragm is
secured. The size of the opening of the diaphragm is engraved in the plate.
After securing the diaphragm, the baffle must be reinstalled, and the glass can be put back or the door can be
closed again.
