Installation and Operating Instructions for Newbourne 35/40/50/60FS Multi Fuel Stoves
Ref: Pevex1022/AH/ver1:May2015
Well seasoned woodfuel is essential for correct use. Make sure your fuel is kept dry. If the fuel is wet, a large
proportion of the heat will be used to vaporize the water, and this energy will disappear up the chimney. It is
clearly not only uneconomical to fire with wet fuel but also, as mentioned above, increases the risk of producing
soot, smoke and other environmentally damaging by-products. When wood is used as a fuel, it is important
that it is dry, i.e. wood with moisture content less than 20%. Ideally firewood needs seasoning for at least 2
summers, logs should be stacked in a well ventilated situation, and logs over 100mm diameter should be split.
The stack should be protected from rain but remain well ventilated.
Generally dry wood (<20% moisture content) produces 4.5kW/h per kg; semi dry about 3kW/h per kg and wet
wood 1kW/h per kg demonstrating that fewer drier logs are required to produce the same amount of heat
output.

FUELS USED IN SMOKE CONTROL AREAS
In a building in a smoke control area you are legally only allowed to use this appliance to burn dry/seasoned
wood logs of the maximum length given above or authorised fuels. If you are unsure if your property is located
in a smoke control area or need further guidance on fuels you should contact your Local Authority.
MIXED FUEL USE
Use of brown coal and smokeless fuel
Uni-logs (brown coal brickettes) may be burned on the stove. Good performance will be obtained using these
brickettes. Approved smokeless solid fuels such as ancit may also be used. Avoid over firing. A mixture of
seasoned wood and smokeless fuel will provide extended burn times with a good flame picture.
USE OF BROWN COAL OR OTHER NON-AUTHORISED FUELS SHOULD NOT BE USED ON THE
APPLIANCE IF LOCATED IN A SMOKE CONTROL AREA UNLESS IT IS PART OF A MANUFACTURED
AUTHORISED FUEL.
It is essential when burning smokeless solid fuels that the ashpan is emptied on a daily basis. Ash must not be
allowed to build up below the grate. Note brown coal and smokeless fuel should also be stored dry and
ventilated.
Use of Petroleum coke, liquid fuels, house coal
and unauthorised fuels
will invalidate the guarantee and
must not be used
as this will cause the stove to “over fire” as well as damaging the internal components.
Operating at temperatures in excess of 500ºC will cause irreparable damage which is not covered by the
guarantee. B
urning any “contaminated” or treated wood which may have been painted, varnished,
oiled/stained or materials such as MDF or plywood which contain resins/glues should never be used as this will
cause an over-fire situation resulting in damage to the glass and bricks not to mention the toxic gases emitted
into the atmosphere. Also, never burn bituminous house coal which is designed for open fires and not for use
in stoves as this fuel is very volatile and gaseous containing lots of sulphur which will
permanently etch
marks in the glass
as well as potential damage to the bricks, baffles and grate.
