4.9 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 1 meter!
4.9.1 Flue routing
-
The terminal locations, through the wall as well as through the roof
-
A horizontal extension with elbows is allowed for a maximum of 5 meters (depending
on the type and situation)
-
Vertical max. 12 meters. (depending on the type and situation)
Determine on the base of Appendix A and B 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:
o
Each elbow, which is in the horizontal area, counts for 2 meters;
o
Each 45-degree bend, which is in the horizontal area, counts for 1 meter;
o
Elbows and bends at the transition of horizontal to vertically are not to be
counted;
o
The wall mounted terminal counts for 1 meter.
4.9.2 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.
