OPERATING INSTRUCTIONS FOR THE

CHARNWOOD LA30iB

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 following smokeless fuels.

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
Multifuel Instruction Supplementíí.

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, an
approved fuel distributor, or the Solid
Fuel Association (tel. [phone])
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.

LIGHTING

CONTROLLING THE

FIRE

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.

Control
Knob

FUELS

HETAS Ltd. approval only covers the
use of the following smokeless fuels
on this appliance:

Ancit,
Anthracite Large Nuts,
Centurion,
Cosycoke,
Extracite,
Maxibrite,
Phurnacite,
Sunbrite Doubles,
Welsh Dry Steam Coal (Large Nuts).

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.

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.

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.

Before relighting the fire, riddle,
remove any clinker from the firebed
and empty the ashpan.

Air Inlet

Damper

Fig.1.ThermostatControl

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
position when burning any of the
recommended fuels except for

anthracite, or homefire which should
be burnt with the secondary air inlet
open.

RUNNING THE FIRE

WITH THE DOORS

OPEN

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.

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.

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.

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.

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.

Care should be taken to ensure that
ash is cool before emptying it into
plastic liners or bins.

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.

After riddling, the grate should be put
back into the solid fuel position (the
tool should be horizontal).

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.

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

Fig.2.SecondaryAirControl

HEATING SYSTEM

The heating system controls may
consist of time switches, room
thermostats, outdoor temperature
thermostats and thermostatic radiator
valves in virtually any combination.
These will work in conjunction with
the thermostat control on the fire. The
thermostat on the fire will simply
control the temperature of the boiler
and hence the temperature of the

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.

Caution: when riddling the grate
using solid fuel do not go beyond the
45° position as this can cause the
grate to jam.

If jamming does occur then the fire
should be allowed to burn for
approximately half an hour before
riddling the grate again as described
above.

Too much riddling can result in
emptying unburnt fuel into the ashpan
and should therefore be avoided.
Clinker should regularly be removed
from the firebed.

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.

Some experimentation may be
necessary to find the setting most
suitable for the particular fuel used
and the draw on the chimney.

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.

THROAT PLATE AND

FLUEWAY CLEANING

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.

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.

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.

Cleaning the Glass

The glass in the doors is a special
ceramic glass which is able to
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.

When not in use

If the fire is going to be out of use
for a long period, (for instance in the
summer,) then to prevent condensa­tion, 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.

After long periods where the fire has
been out of use, the chimney and
appliance flueways should be cleaned
before lighting.

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.

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.

CHIMNEY SWEEPING

The chimney should be swept at least
twice a year. In most installations it
will be possible to sweep the chimney
through the appliance.

First remove the front firebars and the
throat plate. Then sweep the chimney
ensuring that soot is removed from all
horizontal surfaces after sweeping.

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.

After clearing any soot from within
the fire, replace the throat plate and
the front firebars.

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.

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.

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.

As the brick is not cemented into
position, fitting and removing it
should only take a few minutes.

LA30iB3.99

TROUBLE SHOOTING

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.

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.

Over-Firing

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,
b) the thermostat on the fire is
working correctly,
c) a suitable fuel is being used,
d) the fire is not fitted onto a heating
system which is too large.

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
immediate actions should be taken:

A) Open doors and windows to
ventilate the room.
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.

The most common cause of fume
emission is flueway or chimney
blockage. For your own safety these
must be kept clean.

Freezing

Do not light the fire if there is any
possibility that any parts of the
system may be frozen.

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
should cause the chimney fire to go
out in which case the control should
be kept at the minimum setting until
the fire in the appliance has gone out.
The chimney and flueways should

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.

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

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.
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.
e) Ensure that the boiler reduction
brick has not been fitted when it is
not required.

INSTALLATION INSTRUCTIONS FOR THE

CHARNWOOD LA30iB

HEALTH AND SAFETY

PRECAUTIONS

Please take care when installing the
appliance that the requirements of the
Health and Safety at Work Act 1974
are met.

Some types of fire cement are caustic
and should not be allowed to come
into contact with the skin. In case of
contact wash with plenty of water.

If there is a possibility of disturbing
any asbestos in the course of
installation then please use
appropriate protective equipment.

There must not be an extractor fan
fitted in the same room as the fire as
this can cause the appliance to emit
fumes into the room.

There must be an adequate air supply
into the room in which the appliance
is installed totalling at least 100
square cm. (16 square inches) to
provide combustion air. This is
particularly necessary if the room is
double glazed.

In addition to these instructions the
requirements of BS:8303 and
BS:6461 Pt 1&2; 1984 must be
fulfilled. Local Authority Byelaws
and Building Regulations regarding
the installation of Solid Fuel burning
appliances, flues and chimneys must
also be observed.

PERFORMANCE

The rated output for the LA30iB is

6.1 kW (20,800 btu/h) to water and

2.7 kW (9,200 btu/h) to the room.
These are the outputs obtained during
testing in accordance with BS 3378
burning Sunbrite Doubles with the
doors closed over a 4 hourly
re-fuelling interval.

If the optional boiler reduction brick
is fitted and the deepening bar
removed then the output is reduced to

3.0 kW (10,200 btu/h) to water and

2.1 kW (7,100 btu/h) to the room.
The heat output to the room is

directly proportional to the heat

output to water as shown in Fig. 4.
This means that if the water heating
load is less than the rated output then
the room heating will be reduced by
the same proportion. This must be
borne in mind when calculating the
heating requirements.

CHIMNEY

In order for the appliance to perform
satisfactorily the chimney height must
not be less than 4 metres measured
vertically from the outlet of the
appliance to the top of the chimney.
The chimney should preferably be

THAN 150mm (6 INCHES)
INTERNAL DIAMETER OR 150 x
150mm INTERNAL SQUARE.

If an existing chimney is to be used it
must be swept and checked, it must
be in good condition, free from
cracks and blockages, and should not
have an excessive cross sectional area
(eg. greater than 250mm x 250mm).
If you find that the chimney is in
poor condition then expert advice
should be sought regarding the
necessity of having the chimney
lined. If it is found necessary to line

the chimney then a lining suitable for
Solid Fuel must be used.

If there is no existing chimney then a
prefabricated block chimney or a twin
walled insulated stainless steel flue to
BS:4543 can be used either internally
or externally. These chimneys must
be fitted in accordance with the
manufacturers instructions and
Building Regulations.

Single wall flue pipe is suitable for
connecting the fire to the chimney but
is not suitable for using for the
complete chimney.

If it is found that there is excessive
draw in the chimney then a draught
stabilizer should be fitted.

HEARTH

The appliance must be installed on a
fireproof hearth and must be situated
at least 300 mm (12 inches) from any
combustible material. The positioning
of the appliance and the size of the
hearth are governed by building
regulations for Class 1 appliances.
These building regulations state that
the hearth must extend in front of the
appliance by at least 300 mm (12
inches) and to the sides of the
appliance by at least 150 mm (6
inches). If in doubt as to the
positioning of the appliance expert
advice should be sought either from
the supplier or the local building
inspector.

PREPARATION OF

FIREPLACE

Before fitting the appliance into an
existing fireplace remove the fireback
and any loose in-fill material.

The hearth, surround and opening for
the appliance must conform with
Figs. 5 and 6. The flat area around
the opening must be a minimum of
750 mm wide and 660 mm high.
Ensure that the hearth and the base in
the opening are flat, level, and at
right angles to the surround.

Make two holes in the chimney

Page 7

LA30iB 3.99

breast, one in the front to give access
for infilling and fixing the flue pipe,
and one in the side to give access for
the pipework.

CENTRAL HEATING

SYSTEM

The central heating system must
comply with BS:5449 part 1.

If the system is to be a combined
heating and domestic hot water
system then a double feed indirect hot
water storage cylinder to BS:1566
part 1 should be used. In order to
prevent the build up of scale and
corrosion a suitable inhibitor should
be used. The system must be
correctly vented as shown in Figs. 7
and 8. The height differential between
the header tank and the appliance
must not exceed 15.2 metres (50
feet).

If all four boiler tappings are used
then, if possible, diagonal pairs
should be connected for domestic hot
water and central heating. Where a
common return is used an injector tee
must be incorporated into the system
as shown in Fig. 9. This will ensure
that a good domestic hot water supply
is maintained when the central
heating pump is operating.

The system must incorporate a
gravity circuit which will normally
heat the domestic hot water and an
unvalved radiator with an output of at
least 0.75 kW. When the appliance is
not connected to a domestic hot water
system the unvalved radiator(s) on the
gravity circuit must have an output of
at least 1.0 kW. This is to prevent
boiling in case of pump failure.

If the boiler reduction brick is fitted
then the appliance may be used for
room heating and supplying domestic
hot water without the need for a
gravity radiator.

All pipework in the primary circuit
must be 28 mm diameter and the
gravity flow pipe must rise
continuously from the boiler to the
open vent. Two typical systems are
shown in Figures 7. and 8.

If the fire is used to heat a small
central heating system then the heat
output to the room from the fire will

be reduced. Fig. 4. shows the ratio of
space heating to water heating which
can be expected.

SYSTEM CONTROLS

The circulating pump may be
controlled by means of time switches,
room thermostats or outdoor
thermostats. Radiators may be either
manually or thermostatically
controlled. These controls will all

work in conjunction with the
thermostat on the appliance and the
minimum return thermostat.

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
a minimum return thermostat also
ensures that priority is given to the
domestic hot water. These
thermostats are available from
ourselves if you are unable to obtain
them locally.

FITTING THE FIRE

In some cases it may be necessary to
place the connecting flue pipe in the
chimney before fitting the fire into
the fireplace.

Apply fire cement to the rear face of
the sealing flange on the appliance.
Fit the appliance into the opening
ensuring that it is central and that a
good seal is made between the
sealing flange and the face of the
surround.

Remove any excess fire cement from
around the sealing flange.

The fire should be screwed to the
hearth through the holes at the base
of the sealing flange.

Connect the heating system to the
boiler ensuring that the primary flow
pipe rises from the fire. Fill the
system with water and check for
leaks.

FLUE CONNECTION

AND INFILLING

Make the flue connection with the
special 150° elbow part no.
010/AV12. Please note that this item
is ordered separately from the
appliance. The legs of the elbow may
be cut on site to suit the chimney.
Also note that the legs of the elbow
are different lengths to enable some
situations to be catered for by turning
the elbow around.

The end of the flue pipe must line up

with the centre-line of the chimney,
and must also extend to the point
where the chimney narrows to its
final size. Any large voids must be
filled and flaunched to the flue pipe
to ensure that all soot deposits can be
cleared when the appliance is swept.

Ensure that the flue pipe is not
obstructed or restricted in any way
and that all joints are well sealed.

Before infilling cover the front of the
fire to protect it. Ensure that the flue
pipe is central and then fill the space
between the body of the fire and the
structural brickwork with vermiculite
(eg. micafil or similar) concrete.
Ensure that there are no air pockets.
The recommended mix is six volumes
of vermiculite granules to one volume
of portland cement thoroughly mixed
together. Enough water should be
added so that no more than one or
two drops of water are released when
a handful of the mixture is squeezed.

After filling with vermiculite flaunch
the top of the flue connector pipe to
the chimney with lime mortar.

Make good the holes in the front and
side of the chimney breast making
sure that they are completely airtight.
A typical installation is shown in
Fig. 10.

In most installations it will be
possible to sweep the chimney
through the appliance. If this is not
possible then some alternative means
(such as a soot door), must be
provided.

The free-inset method of installation
may be used instead of in-filling.
Details are available on request.

COMMISSIONING

On completion of the installation and

time for the fire cement and mortar to
dry out, the fire should be lit and
checked to ensure that smoke and
fumes are taken from the appliance
up the chimney and emitted safely.
Also check all joints and seals.

The central heating pump should be
adjusted to give the correct water
flow against the circuit resistance and
the system should be correctly
balanced.

On completion of the installation and
commissioning please leave the
operating instructions with the
customer and advise on the use of the
fire and any controls on the system.
