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.
All materials used in the manufacture of air vents
should be such that the vent is dimensionally stable,
corrosion resistant, and no provision for closure.
The effective free area of any vent should be ascer-
tained before installation. The effect of any grills
should be allowed for when determining the effective
free area of any vent.
Air vents should be positioned so that they are not
liable to blockage.
Air vents direct to the outside of the building should
be located so that any air current produced will not
pass through normally occupied areas of the room.
An air vent outside the building should not be locat-
ed less than the dimensions specified within the
Building Regulations and B.S. 8303: Part 1 from any
part of any flue terminal. These air vents must also
be satisfactorily fire proofed as per Building
Regulations and B.S. 8303: Part 1.
Air vents in internal walls should not communicate
with bedrooms, bedsits, toilets, bathrooms or rooms
containing a shower.
Air vents traversing cavity walls should include a
continuous duct across the cavity. The duct should
be installed in such a manner as not to impair the
weather resistance of the cavity.
Joints between air vents and outside walls should be
sealed to prevent the ingress of moisture. Existing
air vents should be of the correct size and unob-
structed for the appliance in use.
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 appli-
ance/flue while the fan is in operation. Refer to B.S.
8303 Part 1.
Note:
There must not be an extractor fan fitted in the
same room as the stove as this can cause the
stove to emit smoke and fumes into the room.
Especially Airtight Properties:-
If the stove is being fitted in a property where the
design air permeability is less than 5m
mally newer properties built from 2006), then a per-
manent ventilation must be fitted to provide 550mm
of ventilation for each kW of rated output.
If a draught stabiliser is also fitted then the require-
2
ment is 850mm
per kW of rated output.
EXTERNAL DUCTED AIR
As the Oisin Eco takes secondary air from the room
through the air inlets over the door the product is not
recommended for use with external ducted air.
COMMISSIONING & HANDOVER
On completion of the installation allow a suitable
period of time for any fire cement and mortar to dry
out, when a small fire may be lit and checked to
ensure the smoke and fumes are taken from the
stove up the chimney and emitted safely to the
atmosphere. Do not run at full output for at least
24 hours.
On completion of the installation and commissioning
ensure that the operating instructions for the stove
are left with the customer. Ensure to advise the cus-
tomer on the correct use of the appliance with the
fuels likely to be used on the stove and warn them to
use only the recommended fuels for the stove.
Advise the user what to do should smoke or fumes
be emitted from the stove. The customer should be
warned to use a fire guard to BS 8423:2002 in the
presence of children, aged and/or infirm persons.
LOCATION
There are several conditions to be considered in
selecting a location for your Stanley Oisin Stove.
a. Position in the area to be heated, central
locations are usually best.
b. Allowances for proper clearances to
combustibles.
c. Allowances for proper clearances for
maintenance work.
