3.2 Flue requirements
•
The appliance is of the type C11/C31. The appliance will need to be supplied with
the approved Faber flue pipes and terminal, it is not possible to supply your own. The
minimum effective height of the flue system must be 1 meter.
•
Flue routing:
•
a horizontal extension with elbows is allowed for a maximum of 6 meters.
•
vertical max. 12 meters (without horizontal extensions only)
Determine with the help of appendix A, B and C if the desired routing is possible.
To establish this you will need to calculate:
ƒ
The effective height (this is the real difference in height between the upper side of
the appliance and the terminal)
ƒ
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 from horizontal to vertically are not to be
counted
4. the wall mounted terminal counts for 1 meter
3.3 Flue restrictor
If applicable, in the table of appendix B is also stated the size of a flue restrictor. This
restrictor needs to be fitted in the combustion chamber when placing the appliance.
Normally the smallest flue restrictor is fitted at production.
3.4 Terminal position
Verify if the required terminal position meets the local installation regulations regarding
disturbance, good functioning and ventilation:
•
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
•
Terminals located close to shared walkways, footpaths etc. could be subject to legal
constraints and this should be pointed out to the customer before installation. If in
any doubt about flue location advice should be sought from local building control, or
if appliance-related, from the manufacturer including wherever possible a
dimensioned sketch
•
Avoid locating the terminal in close proximity to plastic materials such as gutters or
other combustibles. If this is unavoidable then a suitable deflector should be made.
