DOWN DRAUGHTS
However well designed constructed and positioned,
the satisfactory performance of the flue can be
adversely affected by down draught caused by near-
by hills, adjacent tall buildings or trees. These can
deflect wind to blow directly down the flue or create
a zone of low pressure over the terminal.
A suitable terminal or cowl will usually effectively
combat direct down blow but no cowl is likely to pre-
vent down draught due to a low pressure zone.

VENTILATION & COMBUSTION AIR REQUIRE-
MENTS
It is imperative that there is sufficient air supply to
the stove in order to support correct combustion.
The air supply to this appliance must comply with
current Building Regulations Part J, Heat Providing
Appliances. If another appliance is fitted in an adja-
cent room it will be necessary to calculate an addi-
tional air supply.
The minimum effective air requirement for this appli-
ance is 33cm². When calculating combustion air
requirements for this appliance use the following
equation:
550mm² per each kw of rated output above 5kw
should be provided, where a flue draught stabiliser is
used the total free area shall be increased by
300mm² for each kw of rated output.
