OPERATING INSTRUCTIONS FOR THE
CHARNWOOD LA30iB
The above fuels are all suitable for
use in smoke control areas. In
non-smoke control areas other fuels
may also be burnt. For instructions on
burning other fuels please ask your
supplier for the ëëCharnwood
GENERAL POINTS
CONTROLLING THE
FIRE
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.
The rate of burning and hence the
output is controlled by the control
knob on the left hand side of the
appliance, shown in Fig. 1. This is
linked to a thermostat which controls
the boiler temperature. The number at
the top of the knob is the number at
which it is set. Some experimentation
may be necessary to obtain the
desired heat output.

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.
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, an
approved fuel distributor, or the Solid
Fuel Association (tel. 0800 600 000)
to suggest an alternative.
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
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.
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 following smokeless fuels.
Control
Knob
LIGHTING
Place some paper and dry kindling
wood or fire lighters on the grate and
cover with a small amount of fuel.
Turn the thermostat control knob to
the maximum setting and light the
paper or fire lighters. Close the doors
and allow the fire to burn until the
fuel is well ignited then load with
more fuel and adjust the thermostat to
the required level.
FUELS
HETAS Ltd. approval only covers the
use of the following smokeless fuels
on this appliance:
Air Inlet
Damper
Ancit,
Anthracite Large Nuts,
Centurion,
Fig. 1. Thermostat Control
Cosycoke,
Extracite,
Maxibrite,
Phurnacite,
Sunbrite Doubles,
Welsh Dry Steam Coal (Large Nuts).
On initial lighting, the appliance may
smoke and give off an odour as the
silicon paint with which the firebox is
painted reacts to the heat. This is
normal and will cease after a short
time. In the meantime the room
should be kept well ventilated.
There is also a manual secondary air
control which is located above the
door opening as shown in Fig. 2. To
adjust the setting, open the doors and
use the door opening tool to move the
flap to the desired position. This
control should be in the closed
HETAS Ltd. 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.

radiators and domestic hot water. The
automatic controls (other than
thermostatic radiator valves) will
switch the pump (and hence the
radiators) on and off. Your installer
will be able to explain the controls
fitted to your system and how to
operate them.
After riddling, the grate should be put
back into the solid fuel position (the
tool should be horizontal).
RUNNING THE FIRE
WITH THE DOORS
OPEN
REFUELLING
Keep the firebox well filled (the fuel
may be sloped up from the front
firebars), but do not allow fuel to
spill over the top of the front fire
bars. Take care that fuel does not
project over the front fire bars or
damage to the glass may be caused
when the doors are closed. If any
pieces of fuel have been inadvertently
loaded onto the top of the throat
plate, then remove them using the
scraper tool.
The fire may be run with the doors
open. This will result in a reduction
in efficiency and hence heat output,
particularly to the boiler. The more
reactive fuels, like homefire, will
burn better when the doors are open
than fuels like phurnacite, sunbrite
and ancit.
ASH CLEARANCE
The ashpan should be emptied
regularly before it becomes too full.
The most convenient time to remove
the ash is just before riddling the fire
since the ash will then be at itís
coolest. Use the tool provided to
remove the ashpan.
For safety reasons if the fire is to be
left unattended with the doors open
then use a spark guard which
complies with BS 3248.
Never allow the ash to accumulate in
the ashpan so that it comes in contact
with the underside of the grate as this
will seriously damage the grate bars.
Ensure that the air inlet damper is not
prevented from closing by spilled fuel
or ash.
OVERNIGHT
BURNING
Empty the ashpan, if necessary, and
then riddle the fire. If the fire is very
low then it may be necessary to add a
little fuel and turn the thermostat
control up to maximum for a brief
period until the fire is burning
Open
Care should be taken to ensure that
ash is cool before emptying it into
plastic liners or bins.
Secondary Air
Flap (shown
closed)
To make ash removal easier there is a
special Charnwood ash carrier
available. This may be purchased
from your supplier or, in case of
difficulty, from ourselves.
RIDDLING
Riddling twice a day is usually
sufficient.
The fire should be riddled with all
doors shut. Place the tool on the knob
and rotate between the horizontal and
the 45° position several times as
shown in Fig. 3.
Do Not Go Beyond

brightly before filling with fuel. If the
central heating pump is off overnight
then the thermostat may be left at the
same setting for both day and night
operation. If the central heating pump
is on overnight then set the thermostat
control to give the required level of
heating.
Cleaning the Glass
The glass in the doors is a special
ceramic glass which is able to

The chimney should be swept at least
twice a year. In most installations it
will be possible to sweep the chimney
through the appliance.
withstand high temperatures. Before
cleaning the glass open the doors and
allow them to cool. Clean the glass
using a damp cloth and then wiping
over with a dry cloth. Any stubborn
deposits on the glass may be removed
with a proprietary stove glass cleaner
or ceramic hob cleaner. Some
deposits on the glass may be burnt off
simply by running the fire at a fast
rate for a few minutes. Do not use
abrasive cleaners or pads as these can
scratch the surface which will weaken
the glass and cause premature failure.
Aerosol spray cleaners should not be
used near the appliance whilst it is
under fire.
First remove the front firebars and the
throat plate. Then sweep the chimney
ensuring that soot is removed from all
horizontal surfaces after sweeping.
Some experimentation may be
necessary to find the setting most
suitable for the particular fuel used
and the draw on the chimney.
In situations where it is not possible
to sweep through the appliance the
installer will have provided
alternative means, such as a soot
door. After sweeping the chimney,
the appliance flue outlet and the flue
pipe connecting the fire to the
chimney must be cleaned with a flue
brush.
For overnight burning the fire doors
must be closed.
To revive the fire, empty the ashpan
if necessary, riddle, and turn the
thermostat control knob to maximum.
When the fire is burning well load on
more fuel as necessary and turn the
control knob to the desired setting.
When not in use
After clearing any soot from within
the fire, replace the throat plate and
the front firebars.
If the fire is going to be out of use
for a long period, (for instance in the
summer,) then to prevent condensa-
tion, and hence corrosion, the
thermostat should be left at the
maximum setting and the main doors
left ajar. It is also advisable to sweep
the chimney and clean out the fire.
Spraying the inside of the doors and
firebox with a light oil, such as
WD40, will also help to keep all
internal parts working well.
THROAT PLATE AND
FLUEWAY CLEANING
Different types of sweepís brushes
are available to suit different
flueways. For standard brick
chimneys a wire centre sweepís brush
fitted with a guide wheel is
recommended. For prefabricated
insulated chimneys the manufacturers
instructions with regard to sweeping
should be consulted.
It is important that the throat plate
and all the appliance flueways are
kept clean. They should be cleaned at
least monthly, and more frequently if
it if found necessary.
The throat plate and flueways may be
cleaned with a low fire still burning.
Use the scraper tool to scrape any
sooty deposits to the front of the plate
until they fall off into the fire. Ensure
that soot deposits are not allowed to
build up on the side boiler faces
because if the throat plate becomes
tight between the faces this can cause
it to fail prematurely.
After long periods where the fire has
been out of use, the chimney and
appliance flueways should be cleaned
before lighting.
BOILER REDUCTION
BRICK
The optional boiler reduction brick
may be used when reduced outputs
are required, e.g. during the summer
or when the fire is fitted on to a small
heating system.
Door Seals
For the fire to operate correctly it is
important that the door seals are in
good condition. Check that they do
not become worn or frayed and
replace them when necessary.
More soot will be deposited on the
throat plate and in the flueways if the
appliance is run at low levels for long
periods. If this is the case then more
frequent cleaning will be necessary.
To fit the brick, let the fire out, clear
the grate of any ash and fuel, and
scrape the boiler faces clean. Lift out
the deepening bar and front firebar.
Fit the brick into the fire with the
thick part of the brick at the bottom
and the sloping face at the front as
shown on the parts list. Push the
brick hard up against the rear face of
the boiler. The brick should rest on
the side fireplates and should be clear
of the grate bars. Replace the front
firebar and deepening bar.
Servicing
It is recommended that the fire is
serviced once a year to keep it in first
class working order. After cleaning
out the firebox thoroughly, check that
all internal parts are in good working
order, replacing any parts that are
beginning to show signs of wear.
Check that the doors seals are in
good condition and that the doors
seal correctly. Check the operation of
the thermostat, both when cold and
hot. A servicing guide, TIS 48. is
available on request.
MAINTENANCE
Cleaning
The appliance is finished in vitreous
enamel. To clean the surfaces simply
wipe over with a dry cloth. Abrasive
pads and scouring cleaners must not
be used as these will damage the
finish. Care should be taken not to
knock the enamel with hard objects
as it will chip.
As the brick is not cemented into
position, fitting and removing it
should only take a few minutes.
Page 5
LA30iB 3.99
then be cleaned. If the chimney fire
does not go out when the above
action is taken then the fire brigade
should be called immediately.
TROUBLE SHOOTING
Fume Emission.
Warning Note: Properly installed
and operated this appliance will
not emit fumes. Occasional fume
from de-ashing and re-fuelling may
occur. Persistant fume emision is
potentially dangerous and must not
be tolerated. If fume emission does
persist then the following
Fire Will Not Burn.
Check that:
a) the air inlet is not obstructed in
any way,
b) chimneys and flueways are clear,
c) a suitable fuel is being used,
d) there is an adequate air supply into
the room,
e) an extractor fan is not fitted in the
same room as the fire.
After a chimney fire the chimney
should be carefully examined for any
damage. Expert advice should be
sought if necessary.
Lack of Heat To
Radiators / Hot Water
immediate actions should be taken:
A) Open doors and windows to
ventilate the room.
Check that:
a) the fire is burning properly - if not
then carry out the checks under "Fire
Will Not Burn".
b) the throat plate is fitted correctly
(see Fig. 4.) and that it is not
distorted.
B) Let the fire out and safely
dispose of fuel from the appliance.
C) Check for flue or chimney
blockage, and clean if required.
D) Do not attempt to relight fire
until cause of fume has been
identified, if necessary seek
professional advice.
Fire Blazing Out Of Control.
Check that:
a) the doors are tightly closed,
b) the thermostat knob is turned down
to the minimum setting,
c) the air inlet damper is closed (at
the bottom left of the appliance), and
that it is not prevented from closing
completely by a piece of ash,
d) a suitable fuel is being used,
e) the door seals are in good
condition.
c) the door seals are in good
condition.
d) If the hot water goes cold when
the pump is turned on, or if some
radiators are hotter than others, then
the system may need balancing, the
pump may be pumping the water too
quickly around the system, or the
radiators may need bleeding. Please
ask your installer to check these
points.
The most common cause of fume
emission is flueway or chimney
blockage. For your own safety these
must be kept clean.
Freezing
Over-Firing
Do not light the fire if there is any
possibility that any parts of the
system may be frozen.
If the fire is over-fired it will cause
premature failure of the internal fire
parts. Overfiring is occurring when
any internal parts of the fire begin to
glow red. To prevent over-firing
ensure that:
a) the door seals are kept in good
condition, and that the doors are
sealing correctly,
e) Ensure that the boiler reduction
brick has not been fitted when it is
not required.
Chimney Fires.
If the chimney is thoroughly and
regularly swept, chimney fires should
not occur. However, if a chimney fire
does occur turn the control knob to
the minimum setting, and tightly close
the doors of the appliance. This

We recommend fitting a pipe
thermostat onto the gravity return and
wiring it into the mains supply to the
pump so that if the gravity return
temperature drops below 45°C then
the pump will cut out. This will help
to prevent condensation forming on
the boiler faces and will thereby
increase the life of the boiler. Use of
