3.5 Sample flue configuration calculation
Step 1
Consider which flue configuration is required
Step 2
Calculate the length of the desired concentric part (
C
) of your
configuration.
Note:
Do not forget to include the bends and negative flue in
your calculation.
Step 3 - option a
Then calculate the desired lengths from supply to the adapter
(
A
) and discharge from the adapter (
B
1
) and (
B
2
). For your
convenience, always choose the longest of both. So you only
have to calculate the length once.
Enter the formula "
L
= 20 - 2/3 *
K
" to see how long your supply
and removal can be.
•
K
is the length of your concentric part.
•
L
is the maximum length of the supply and discharge
Step 3 - option b
Check whether the discharge lengths for the supply to - and
the discharge from the adapter are permitted with the desired
concentric length, by reading in table 3.2 the maximum length
of the remaining air supply / flue gas discharge (
L
) corresponding
to the desired concentric length (
K
).
If
L
is less than or equal to the desired length, you can install
your flue configuration without any problems.
Step 4
Add
K
and
L
to determine the full length of your flue.
For
K
and
L
together, this distance may never be longer than 30
meters and the Powerfan should be always minimum of two
meters away from the fireplace (distance
B
1
).
