3.1.2 False chimney brest RELAXED L with frame
•
Make a framework of metal studs around building guides A and B (fig. 3-1); keep in
mind the thickness of the Promatec you use!
•
Place metal studs at every corner of the false chimney brest; keep in mind the
thickness of the Promatec you use!
•
Build with Promatec around the appliance against the building guides A and B (fig.3-1);
keep in mind that the appliance has to stick out of the walll and therefore nothing
must be build before the building guides!
•
Build the rest of the false chimney brest

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
•
a horizontal extension with elbows is allowed for a maximum of 5 meters
(depending on the situation)
•
Minimal 1 meter vertical and maximal 12 meters vertical (depending on situation)
Determine on the base of the example calculations in Appendix A and on the base of the
table in Appendix B 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:
1. each 90-degree bend, which is in the horizontal area, counts for 2 meter
2. each 45-degree bend, which is in the horizontal area, counts for 1 meter
3. elbows and bends at the transition of horizontal to vertically are not to be
counted
4. the wall mounted terminal or roof terminal counts for 1 meter
3.2.1 Terminal position
Verify if the required terminal position meets the local installation regulations regarding
disturbance, good functioning and ventilation (see also appendix G).
Note:
•
The terminal must be located so that the outlet is not obstructed. If the flue
terminal is located within 2 meters of a footway path or where people could come
into contact with it, then a suitable terminal guard must be fitted
