3.2 Flue requirements
The appliance is of the type C11/C31. The appliance will need to be
supplied with the approved flue pipes and terminal, it is not possible to
supply your own.
The minimum effective height of the flue system must be 0.5 or 1 meter,
depending on the appliance.
Terminal locations, through the wall as well as through the roof. See
figure 3.
Flue routing;
- a horizontal extension with elbows is allowed for a maximum of
6 meters (depending on the type and situation).
- vertical max. 12 meters.
Determine on the base of the table 2 and 3, depending on the type
and terminal position, if the desired situation is possible.
To establish this you will need to calculate:
- The effective height (this is the real difference in height between the
upper side of the appliance and the terminal).
- The total horizontal extension. This is the total horizontal flue length
where:
• each elbow, which is in the horizontal area, counts for 2 meters.
• each 45-degree bend, which is in the horizontal area, counts for
1 meter.
• elbows and bends at the transition of horizontal to vertically are
not to be counted.
• the wall mounted terminal counts for 1 meter.
Flue restrictor
If applicable, in the table is also stated the size of a flue restrictor.
This restrictor needs to be fitted in the combustion chamber when
placing the appliance ( see chapter 4.2). Normally the smallest flue
restrictor is fitted.
