Installation and Operating Instructions for Newbourne 40i Inset Inset Ecodesign Multi Fuel Stove
Ref: Pevex1030/AH/ver1: 1 April 2019
Once the lower vermiculite baffle has been removed then it is possible to remove the upper steel baffle and gain
access to the flue. Removal is achieved by un-doing the 2 allen key locking bolts by 1-2 turns and drawing it
forward to allow the bolt heads to pass through the slots. Reassemble is the reverse by hooking the front of the
baffle over the bolt heads and sliding it backwards and retighten the bolts.
CHIMNEY IMPORTANT WARNING
This stove must not be installed into a chimney that serves any other heating appliance. The chimney must be
a minimum height of 4.5 metres overall height and be in accordance with Building Regulations Approved
Document J and reference should be made to British Standard BS EN 15287-1:2007 design, installation and
commissioning of chimneys. Any chimney, either masonry or a prefabricated stainless steel system must be
constructed and installed according to building regulations. It is recommended that the minimum diameter of
the flue liner be 150mm although for a smoke approved appliance then a 125mm can be used. For new masonry
chimneys we recommend pumice cement liners.
A chimney draught of at least .06” (12Pa or 1.5mm) is
recommended. If it is found that there is excessive draught in the chimney then a draught stabiliser should be
fitted.
Provision must be made for easy sweeping of the chimney. A soot door can be built into a masonry chimney
and flue pipe is available with cleaning doors.
Any bend in the chimney or connecting fluepipe should not exceed 45º and 90º bends should not be
used.
THE CHIMNEY CONNECTION.
The flue pipe for connecting the appliance to the chimney must be installed according to Building Regulations
Approved Document J and its diameter must be not less than the diameter of the outlet of the appliance. The
fluepipe must be adequately sealed to both the stove and the chimney to avoid any leakage.
We recommend also that no more than 1metre of plain un-insulated flue pipe be used to connect to the chimney.
ALL CHIMNEYS SHOULD BE SWEPT AND INSPECTED BEFORE INSTALLATION OF ANY APPLIANCE
For relining existing chimneys 316 or 904 grade stainless steel liners or pumice cement liners in accordance with
Building Regulations Approved Document J should be used. Liners should be suitably insulated. We
recommended that any chimney relining is carried out by an experienced and competent installer who is HETAS
registered (see www.hetas.co.uk). The HETAS Guide to Approved Products and Services lists Chimneys and
lining systems suitable for use with solid fuel.
SWEEPING THROUGH NEWBOURNE 40I INSET.
It is possible to sweep through the Newbourne 40i Inset Ecodesign Stove. Remove the baffles as described
above, and access can be gained to the flue pipe.

2
per kW output will be required
(4kW x 550mm = 2200mm
