1.4.3. Peripheral Distances of Flue Output Connections
In order to position the flue set output pipe
1.4.4. Installation with Horizontal Flue Sets
Connecting Horizontal Concentric Flue Set to the Combi, (original
diameter DN 60/100 mm)
Since your combi is hermetic model, it takes the used air from exterior and
discharges exhaust gases created as the result of burning through the same
flue group. In order to prevent emission of excessively harmful exhaust gases,
flue usage and installation is very important, therefore warnings should be
taken into consideration when flue connections are being performed.
• Make required flue selection for the flue connection to be made externall
and installation place of the combi. If the standard flue set is not
adequate, please select most suitable elements from our list of connection
accessories considering warnings given in our user's guide.
• Fix the flange under the Bend piece (1) by using the Flange Bolt (10) via
Flange Connection Screws (11) to holes on the combi.
• 2 impermeability bolts within the hermetic flue set (2) are placed into
internal pipe slots at both ends of the 90° Bend.
• Place the exterior wall (EPDM) bolt into the flue terminal as seen in Figure
19 for grouping the flue output terminal. After placing the flue output
terminal through exterior of wall and the previously opened hole, fix the
Interior Wall Connection Bolt (7) into the flue terminal.
