!Caution
-
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.
6.5.3
Application with roof duct
6.5.3.1
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 of the concentric system, the appliance is set by placing the baffl e and/or removing
the air inlet guide.
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:
The number of bends required (no distinction is made between 45° and 90° bends);
The total number of meters of horizontal pipe length;
The total number of meters of vertical and/or sloping pipe length.
These data will help you determine whether the concentric system is allowed by using Table 1.
In Table 2 you can read which setting is required for the appliance.
Follow the procedure described below:
➠
In the fi rst 2 columns of Table 1, search the number of bends required and the total horizontal pipe length:
➠
In the 3
rd
column of Table 1, search the total vertical and/or sloping pipe length.
➠
If you end up in a box with the letter A, B, C or D, the concentric system chosen by you is allowed.
➠
Use Table 2 to determine which conditions apply for the baffl
e and/or the air inlet guide (for placing/setting see section
6.7).
Examples
To clarify, we will give 2 examples to determine the allowability of a concentric system and the conditions for setting
the appliance.
In Table 1 the route to be followed is indicated by arrows. The result is indicated by a red frame surrounding the
box.
Example 1
1)
2 bends
2)
3 meters horizontal
3)
8 meters vertical/sloping
Construction of this concentric system is allowed.
Situation B applies for setting the appliance
Example 2
1)
3 bends
2)
4 meters horizontal
3)
9 meters vertical/sloping
Construction of this concentric system is not allowed.
