Stanley Ardmore Installation And Operating Instructions Manual page 10

If there is an extraction fan fitted in adjacent rooms
where this appliance is fitted, additional air vents may
be required to alleviate the possibility of spillage of
products of combustion from the appliance/flue while
the fan is in operation. Refer to B.S. 8303 Part 1.
Where such an installation exists, a test for spillage
should be made with the fan or fans and other appli-
ances using air in operation at full rate, (i.e.extraction
fans, tumble dryers) with all external doors and win-
dows closed.
If spillage occurs following the above operation, an
additional air vent of sufficient size to prevent this oc-
currence should be installed.
Especially Airtight Properties:-
If the stove is being fitted in a property where the de-
sign air permeability is less than 5m
mally newer properties built from 2006), then a
permanent ventilation must be fitted to provide
2
550mm of ventilation for each kW of rated output. If
a draught stabiliser is also fitted then the requirement
2
is 850mm per kW of rated output.

EXTERNAL DUCTED AIR
An outside air kit complete with primary air supply
can be ducted from outside and is available to order
for connection to the stove.
It is recommended to bring the air supply for the stove
into the house using a 4" plastic pipe. Where the pipe
meets the outside wall make sure a vent cover is fit-
ted properly to ensure no rodents can enter via the
vent pipe.
The vent pipe should be located to prevent the
ingress of moisture and in a location where it will not
get blocked with leaves or any other debris. As wind
effects can create suction and pressure zones on
opposite sides of the dwelling it is recommended to
run the air vent from opposite poles (North, South,
East & West) of the dwelling and tee off for the air
