SOLO - INSTRUCTION FOR INSTALLATION
6.6.2.2 Indirect connection to the wall duct
The concentric system has to comply with the following conditions (see Fig. 4b):
- First, a concentric pipe of at least 1 meter should be connected vertically to the appliance;
- The total vertical pipe length can have a maximum of 4 meters;
- After the vertical part a bend of 90° is connected;
- The total horizontal pipe length can have a maximum of 4 meters (wall duct excluded).
Under these conditions, the restriction will not be placed.
!Caution
The top plate of the appliance is placed with the opening on the top.
➠
Build the system up from (the connection stump of) the appliance;
➠
Connect the (lacquered) concentric pipe pieces and the (lacquered) bend;
➠
On each connection, apply a (lacquered) clip binding with silicon sealing ring;
➠
Use a parker to x the clip binding to the pipe on locations that are unreachable after installation;
➠
Apply sucient clamps, so that the weight of the pipes does not only rest on the appliance;
➠
Determine the remaining length of the wall duct;
➠
Make sure the wall duct has the right dimensions.
!Caution
- For G20, the primary aeration burner must be adjusted.
- Make sure that the right insertion length is maintained;
- Place the wall duct with the groove/folded seam at the top;
- Make sure the horizontal concentric pipe pieces are sloping towards the wall duct, in order to prevent rain water
from entering.
➠
Mount the rosette (mounting inner plate); if necessary, on a heat resistant intermediate plate when passing through
combustible material
➠
Attach the wall duct from the outside with four screws in their respective holes.
6.6.3 Application with roof duct
6.6.3.1 Construction of concentric system with roof duct
The concentric system with roof duct has to comply with the following conditions:
- The construction of the chosen system has to be allowed. (See the procedure described below);
- First, a concentric pipe of at least 1 meter should be connected vertically to the appliance.
Depending on the construction, the appliance will be adjusted by means of the baffle.
In the following procedure you can see how the allowability of a concentric system can be determined and which
settings are needed.
➠
Determine the following data:
1) The number of bends required (no distinction is made between 45° and 90° bends);
2)The total number of meters of horizontal pipe length;
3) The total number of meters of vertical and/or sloping pipe length.
With these data and Table 1 you will be able to determine whether the concentric system is allowed. In Table 2 you
can see which setting the appliance needs.
Proceed as follows:
➠
In the rst 2 columns of Table 1 look for the number of bends required and the total horizontal pipe length;
➠
In the 3rd column of Table 1 look for the total vertical and/or sloping pipe length.
If you end up in a box with the letter A, B, C, D or E, the concentric system chosen by you is allowed.
➠
Use Table 2 to determine which conditions apply for the bae (for adjusting, see section 6.8).
