must be
confirmed with HETAS or Local Authority
Building Control and all
Current National laws, Building regulations and any Rules in Force).
An over-sized chimney is generally hard to keep warm and results in poor draft. In cases where there
is an oversized masonry chimney, it is highly recommended that the chimney be lined using an
appropriate and approved chimney lining system with the correct internal diameter as stated above.
With respect to the chimney termination, all chimneys
must
terminate in accordance with
Current
National and Local Building Regulations.
Note:
Current National and Local Regulations
also apply with regard to the placement of chimneys
and flues in connection with thatched roofs.
The chimney or flue system
must be
equipped with access doors for inspection and cleaning. The
size of the cleaning door in the chimney must at least equal to that of the cross-sectional area of the
chimney. In the event that a chimney fire occurs resulting from faulty operation or prolonged use of
damp wood fuel, if safely possible close the air vents of the stove completely, evacuate all persons
from the building and contact your local fire department immediately.
3.4.1 Stove Pipe connection
Refer to: Current National laws, Building Regulations, and any Rules in Force including BS 8303 and
BS EN 15287-1:2007 and (Approved Document J England & Wales)
There are two stove flue exits enabling either top or rear venting depending on installation
requirements. See figure 3.
Check that the flue collar adaptor and flue blanking plate rope seals are not damaged and in correct
position.
The flue collar adaptor is fixed using 3 x nuts, bolts, and washers.
The blanking plate to blank the redundant flue position is supplied with a fixing clamp and bolt fixing.
Ensure that the flue collar adaptor and blanking plate are fully sealed to the stove when installed.
Top flue exit position
If using the stove top flue exit position.
Check that the flue collar adaptor rope seal is not damaged and in correct position.
Align the flue collar adaptor to the stove top flue exit position ensuring the 3 flange bolt hole
positions align with the 3 holes to the stove top flue exit position.
Pass each bolt provided through each flue collar adaptor flange into the corresponding holes within
the stove top, place the washer and screw each nut to each bolt that can be accessed through the
top flue collar. Evenly tighten the 3 nuts and washers so the flue collar adaptor is securely fastened
to the top of the stove.
Rear flue exit position
If using the rear flue exit position, remove the rear flue blanking plate by removing the bolt and
clamp located to the rear of the blanking plate.
Check the flue blanking plate rope seal is in correct position and not damaged.
Install the flue blanking plate to the stove top flue position as described above.
Securely bolt the flue collar adaptor to the stove rear exit flue position as described above.
A suitably gauged metal rigid stove flue pipe of the correct size
complying
with
Current National
laws, Building Regulations, and any Rules in Force
(not supplied), is connected to the flue collar. This
part is not supplied.
The joint between the stove collar and rigid stove pipe
must be
fully sealed using suitable stove rope
/ fire cement. When the rigid stove flue pipe is
fully
inserted into the stove flue collar drill two
suitably sized holes in a suitable position 180
apart through the stove flue collar and rigid stove pipe
and use either corrosion proof self-tapping screws or bolts, nut, and washers of a suitable size to
