CONTENTS

References in this manual to British Standards and
Statutory Regulations and Requirements apply only
to the United Kingdom. For Ireland the rules in
force must be used.
Before installation, check that the local distribution
conditions, nature of the gas, pressure and the
adjustment of the appliance are compatible.
The manual is an important part of the appliance
and must by law be handed to the end user on
completion of the installation.

SAFETY NOTICES

• Do not attempt to burn rubbish or any other
material in this appliance.

• This fire must only be operated with the fire

door shut and secured.

• Do not use the appliance if the glass is cracked or
broken.

• Do not make any unauthorised
modifications to the appliance.

• It is recommended that the fire be guarded
to protect the young and infirm using a
fireguard complying with BS8423:2002.

• Coal set -The coal set contains Refractory

Ceramic Fibres (R.C.F), which are man
made vitreous silicate fibres. Excessive
exposure to these materials may cause
temporary irritation to the eyes, skin and
respiratory tract. Care must be taken when
handling these items to ensure the release of
dust particles is kept to a minimum. To
ensure that the release of fibre from these
items is kept to a minimum, during
installation and servicing it is recommended
that a vacuum cleaner fitted with H.E.P.A.
filters is used to remove any dust, soot or
any other debris accumulated in and around
the appliance. This should be performed
before and after the installation. It is
recommended that any replacement item(s)
are not broken up but sealed within a heavy

duty polythene bag and clearly labelled
"R.C.F. waste". This is not classified as
"hazardous waste" and may be disposed of

at a tipping site licensed for the disposal of

industrial waste. Protective clothing is not

required when handling these items but it is

recommended that gloves are worn and

normal hygiene rules are followed.
Always wash your hands before eating or
drinking.

• In the event of a gas emergency, consult the

telephone directory and ask for your local
gas supplier.

FITTING THE LINING PANELS

Becton 7 only. The lining panels supplied are to be

installed into the fire before the coal matrix is
fitted. Note: The lining panels are reversible (brick
or plain pattern)

Ensure the appliance is cold.
With the fire door open, the glass retaining frame
and the coal set removed, proceed as follows:
Do not force the linnings into position.

1. Position the rear lining face

down at the rear of

the fire. Ensure the cutout faces the rear of the fire.

Fig. 3a Positioning the rear lining

2. Locate side lining in the right hand side of the

fire. First position the tall edge into the radius at the
front of the fire.(See Fig.3b below)

Fig. 3b Fitting the R/H side lining

3. Then rotate the rear edge until the top faces
match up the angle faces at the rear of the fire.
(See Fig. 3c) Repeat exercise for the left hand side.

Fig. 3c Fitting the side linings

4. Rotate the rear lining to bring it vertical (Fig. 3d)

Fig. 3d Rotating the rear lining

5. Centre the assembly. Line up each end of the rear
lining with the edges of the fixed matrix plate. (See

Fig. 3e)

Fig. 3e Liner panels assembled in the fire.

Once the lining panels are fitted, arrange the coals.
See “Arranging the coals” on page 8.

OPERATING INSTRUCTIONS

ARRANGING THE COALS

Safety Notice - Please see SAFETY NOTICES
ref. Coal set page 4.
Warning: The coals and the coal matrices are
fragile ensure they are handled carefully.
Ensure location is correct. Do not force the
matrix into position. If the coals and/or the coal
matrices are damaged they must be replaced
with genuine Aarrow replacement sets.
Warning: An incorrect coal layout may cause
soot to build up inside the fire and therefore
invalidate the guarantee.

Ensure the appliance is cold.
Step 1 Place the base matrix on the matrix plate
centrally between the end tabs of the location bar.
(Fig 4a)

Fig 4a

Step 2 Place the rear matrix cut out section over
the base matrix and centralise the assembly
between the end tabs of the location bar. Ensure the
rear matrix is pushed back against the location bar.
(Fig 4b)

Fig 4b

Step 3 Becton 7 only. Locate 2 off end coals each
side of the base matrix. (See underside of coals for
hand identification) (Fig 4c).

OPERATING INSTRUCTIONS

LIGHTING & CONTROLLING
THE FIRE

Under no circumstance must the fire be operated if
the glass is cracked or broken.

Open the gas control access door situated at the
bottom of the appliance. Always use the control

door HANDLE.

Step 1a. To ignite the pilot push the control knob in,
turn anti-clockwise towards the spark position and
hold in for 15 seconds. (Fig 5a)
The pilot can be viewed through the L/H & centre
front slots in the base matrix.

Fig 5a

Step 1b. Keep the control knob pressed in and turn

anti-clockwise to the pilot position. (Fig 5b)

Fig 5b

Step 1c. Keep the control knob pressed in for a
further 15 seconds and then release. The pilot will
remain alight.

If pilot does not remain alight repeat this procedure.

Please note that when purging the gas supply it is
usual to have to keep the control knob depressed in
the spark position for longer periods of time.

Step 2. To ignite the main burner, rotate the control
knob anti-clockwise to the HIGH position (fig 5c)

Fig 5c

For maximum heat output leave the control knob at
the high position

For minimum heat output, rotate the control knob
clockwise to the LOW position. (Fig 5d)

OPERATING INSTRUCTIONS

Fig 5d

Fig 5e

Step 3. To turn the main burner off while keeping
the pilot alight, rotate the operating knob back to
the PILOT position. (Fig 5e)

Fig 5f

Step 4. To extinguish the pilot, turn the control knob
to the OFF position. (Fig 5f)

Incorporated into the pilot assembly is a flame
failure device designed to shut off the gas supply in
the event of the pilot flame being extinguished
while the fire is unattended.
Should the pilot flame blow out accidentally or
intentionally whilst the fire is running, no attempt

should be made to re-light the gas for at least
three minutes.

To restart the fire turn the control knob to the off
position and repeat the lighting & controlling the
fire instructions.

The flame failure device is a safety feature required
by law and must not be put out of action by the
installer. If this device or any of its parts are to be
replaced, only original manufacturer's parts are to
be used.

Repeated operation of the flame failure device
indicates that there maybe a problem with the flue
draw. In this situation no more attempts at
operating the appliance should take place and your
qualified gas engineer should be contacted to
investigate and rectify the problem.
