Follow the procedure described below:
➠
In the fi rst 2 columns of Table 2, look for the number of bends required and the total horizontal pipe length.
➠
In the 3rd column of Table 2, look for the total vertical and/or sloping pipe length.
If you end up in a box with the letter A, B or C, the concentric system chosen by you is allowed.
➠
Use Table 3 to determine which conditions apply for the baffl e and/or the air inlet guides (for setting, see section 6.8).
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 2 the route to be followed is indicated by arrows. The result is indicated by a box with a red border.
Example 1
1) 2 bends
2) 3 meters horizontal
3) 5 meters vertical/sloping
→ Construction of this concentric system is allowed.
→ Situation A applies for the adjustment of the appliance.
