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 obtained approval by
HETAS Ltd. in the safe and fit for
purpose category.

FUELS

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

Ancit (Phurnacite Plus),
Anthracite Large Nuts,
Cosycoke,
Centurion,
Extracite,
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 fuels are all suitable for
use in smoke control areas. In
non-smoke control areas your

Housing Authority will be able to
advise you if other fuels may be
burnt. For instructions on burning
other fuels please ask your your
supplier or Housing Authority for the
“Charnwood Instruction
Supplement.”

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

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 fire 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.

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 firebox 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.

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 smokeless fuels except
for anthracite and homefire which
