GENERAL POINTS
Before lighting the fire check with
the installer that the work and checks
described in the installation
instructions have been carried out
correctly and that the chimney has
been swept, is sound, and free from
any obstructions.
WARNING There must not be an
extractor fan fitted in the same room
as this appliance as this can cause the
appliance to emit smoke and fumes
into the room.
If the appliance is fitted in place of
an open fire then the chimney should
be swept one month after installation
to clear any soot falls which may
have occurred due to the difference in
combustion between the appliance
and the open fire.
When using the fire in situations
where children or infirm people are
present please use a fire guard to
prevent accidents. The fire guard
should be manufactured in
accordance with BS 6539.
This appliance has been designed to
conform with BS.3378. It has
obtained the approval of HETAS Ltd.
(formerly DSFAAS Ltd.) for burning
the fuels listed under the heading
“Smokeless Fuels”.
FUELS
The following fuels may be burnt on
this appliance. Please pay careful
attention to the special points made
with each type of fuel as they will
help you to get the best from your
fire. It must be remembered that only
smokeless fuels may be burnt in
smoke control areas on this fire. If
you are not sure whether you are in a
smoke control area, then please check
with your Local Authority.
Smokeless Fuels
HETAS Ltd. approval only covers the
use of the following smokeless fuels
on this appliance:
Ancit,
Anthracite Large Nuts,
Centurion,
Extracite,
Homefire,
Maxibrite,
Phurnacite,
Sunbrite Doubles,
Welsh Dry Steam Coal (Large Nuts).
Approval does not cover the use of
other fuels either alone or mixed with
the above fuels, nor does it cover
instructions for the use of other fuels.
The above smokeless fuels are all
suitable for use in smoke control
areas.
Coal
Housecoal doubles, trebles or cobbles
may all be burnt. Do not use singles,
small nuts, or coal dust
It is important that large size coal is
used (ie. larger than 2’’ or 50 mm in
size). The coal should be dry.
When burning bituminous coal a
little extra care is needed. Please take
note of the section ‘‘Special Points
When Burning Coal’’, on page 5.
Wood
Only dry well seasoned wood should
be burnt on this appliance as burning
wet unseasoned wood will give rise to
heavy tar deposits. For the same
reason hard wood is better than soft
wood. Burning wet unseasoned wood
will also result in considerably
reduced outputs. The wood should be
cut and split and then left to season
in a well ventilated dry place for at
least one year but preferably two
years before use.
Peat
Ensure that the peat is well dried
before use. Burning wet peat will
give rise to heavy tar deposits and
reduced outputs.
PETROLEUM COKE IS NOT
SUITABLE FOR USE ON THIS
APPLIANCE, ITS USE WILL
INVALIDATE THE GUARANTEE
At first you may find it helpful to try
several fuels to find the most suitable.
If you are unable to obtain the fuel
you want ask your supplier, or an
approved fuel to suggest an
alternative.
DOOR OPERATION
Use the spanner type tool to open and
close the doors. Turn the knob on the
right hand door anti-clockwise to
open and clockwise to close. When
closing the doors do not push on the
enamel with the tool as this can chip
the enamel, instead push the doors on
the door knobs.
MULTIFUEL GRATE
Your Charnwood is fitted with a
multifuel grate which enables solid
fuel, wood and peat to be burned
equally effectively.
The grate has two positions. One for
solid fuel, the other for wood and
peat. When in the solid fuel position
ash can fall through the grate and
into the ashpan. When in the wood
position ash is able to build up on the
grate as is necessary for effective
wood or peat burning.
Movement of the grate from one
position to the other is effected using
