It is the LAW that all gas appliances and fittings are installed by a competent person (such as a CORGI registered fitter) and in

accordance with the Gas Safety (Installation and Use) Regulations 1998.

INSTALLATION INSTRUCTIONS

IMPORTANT NOTES

This appliance is a high efficiency, flueless catalytic flame effect gas fire. It provides radiant and convected warmth

both efficiently and safely utilising the latest type catalytic converter and burner technology. The appliance does not

require a flue system of any type as the catalytic converter cleans the flue products to provide a complete combus-

tion system, which is intrinsically safe. It is designed to operate on Natural Gas and is factory set for operation on

the gas type, and at the pressure stated on the appliance data plate.

The appliance incorporates a combustion monitoring system (Oxygen Depletion System). It must not be adjusted

or put out of operation. If replaced then manufacturers original parts must be used.

It is the LAW that all gas appliances and fittings are installed by a competent person and in accordance with the Gas

Safety (Installation and Use) Regulations 1998, the relevant British Standards for Installation, Codes of Practice and

the Manufacturers' Instructions. At the time of writing, CORGI registered operatives are the only class of person

considered as 'competent' by the HSE under the above regulations.The installation shall also be carried out in accor-

dance with the following:

• Manufacturers' Instructions.

•The Building Regulations issued by the Department for Communities and Local Government, the Building

Standards (Scotland) (Consolidation) Regulations issued by the Scottish Development Department.

•Relevant British standards insofar as the relevant areas are not covered by these instructions.

•For Republic of Ireland, reference should be made to the current edition of IS813 (the relevant standards

governing installation).

Failure to comply with the above could lead to prosecution and deem the manufacturer’s warranty invalid.

This appliance must be installed in accordance with the rules in force and used only in a sufficiently ventilated space.

The appliance is designed to fit various types of situations as described in sections 3.0 and 4.0.The appliance must

be installed in a correctly sized room (see section 3.1), and the correct purpose provided ventilation must be pro-

vided (see section 4.1).

It should be noted that heaters create warm air currents. These currents move heat to wall surfaces next to the

heater. Installing the heater next to vinyl or cloth wall coverings or operating the heater where impurities in the air

(such as tobacco smoke, candle smoke etc.) exist, may cause the walls to become discoloured.

This appliance is intended as a secondary source of heat only and should not be used in a room without some form

of background heating present. If the appliance is used in a room as the sole source of heat, then condensation may

occur on colder surfaces within the room.

On first light up of a new appliance, initial curing of high temperature paint and burning off of lubricants may occur

for the first few hours of operation. During this period some smoke may be emitted from outlet grille, this should

be no cause for concern. Accordingly, the room should be well ventilated with all windows and doors open during

this period. During this period the appliance may cause smoke alarms to sound. If this happens, reset the alarms, but

do not remove the batteries.

Consult ALL instructions before installation and use of this appliance. This appliance is free from any asbestos mate-

rial.

INSTALLATION REQUIREMENTS

If the appliance is to be sited near a disused or unserviceable fireplace served by a natural draught flue then the old

flue must be sealed off. It will be necessary to ventilate the old flue to prevent condensation and dampness forming,

however any air vent used to ventilate the old flue must not be sited within 500mm of this appliance. If the flue can

be ventilated to the outside of the building then this is usually the best solution. If in doubt then advice should be

sought from a local building control officer. The appliance is designed to be wall mounted. If the appliance is to be

mounted on a newly fabricated area of wall that also serves the purpose of sealing off the old flue then it is very

important that there are no holes, gaps or otherwise in this wall that will allow draughts from the old flue to enter

the room, especially directly behind the appliance. Such draughts could affect the performance of the ODS system

and result in nuisance cutting out, for example. If the gas supply pipe is to enter the appliance from the rear, i.e.

emerge from the wall behind the appliance then any hole in the wall from which the pipe emerges must be tightly

sealed.

Any existing under grate draught device should be sealed off to prevent loss of heat or creation of draughts. It is

possible to install the appliance onto certain types of combustible materials - see section entitled 'Clearances to

combustible materials'.

ROOM SIZING

The room size should be a minimum of 23m3(e.g. 10’1” x 10’1” x 8’) to allow adequate circulation of air and

ensure the correct operation of the fire.This volume may include adjacent spaces but these spaces must not be

separated by a door.To calculate a room size in cubic metres (m3) divide the room volume in cubic feet (ft3) by

35.3.

SITE REQUIREMENTS

This appliance is designed to be wall-hung. Do not recess any part of the appliance into the wall.

This Appliance may be installed in any room in a home, however there are exceptions, and the appliance may not be

used in bedrooms or bathrooms.

Installation in living rooms is common, however other rooms such as kitchens, dining rooms and hallways are per-

mitted, providing a suitable natural gas supply is available, and rooms sizing and ventilation requirements are strict-

ly adhered to (see sections 3.1 and 4.1).

The appliance is designed to be versatile, and as such will operate correctly when exposed to normal gentle draughts

experienced within the home. It is not recommended, however that the appliance be installed in areas where it is

likely to be exposed to persistent strong draughts, that may be generated by outside doors or windows, air vents

etc. It is recommended that the appliance should not be installed within 1 metre of any air vent.

SITE REQUIREMENTS (continued)

Clearances to non-combustibles

Non combustible surfaces are defined as brick, metal, marble, concrete etc. and also a number of man-made mate-

rials impervious to flame. If in doubt refer to the material manufacturer for further information before proceeding

with installation.

Clearances to the sides of the appliance are 100mm (4”). Clearance to the front of the appliance is 500mm (20”).

The back of the appliance may be installed directly onto a non-combustible wall, providing the area behind the appli-

ance is flat and does not interfere with the various vent holes in the back panel of the appliance.

A non combustible shelf of any depth may be positioned above the appliance provided it is no closer than 400mm

from the top of the appliance glass panel and the wall above the appliance is non combustible.

The appliance must not be positioned vertically within 60mm ( 2.4”) of a solid floor (i.e. wood or stone) or hearth.

This dimension is measured vertically to the bottom of the appliance firebox.

Clearances to combustible materials

Combustible materials are defined as wood, fabrics, or other materials likely to combust if exposed to flame.

Generally, any material, which is likely to discolour, melt or misshape when exposed to moderate heat, should be

considered as a combustible material or surface.

Clearance to the sides of the appliance are 100mm (4”) but curtains, drapes and other fabrics are not permitted

within a distance of 500mm(20in) of the appliance sides. No such materials are permitted directly above the appli-

ance regardless of distance.

The minimum clearance to the ceiling above the appliance is 800mm (31.5”) measured from the top of the appliance

glass panel.

Combustible materials should not be positioned directly in front of the appliance within a distance of one metre.

Under no circumstances should any electrical equipment e.g. plasma screen TV sets etc. be positioned on the wall

above the appliance. The appliance is designed to be wall mounted alone and not in conjunction with any type of

combustible fire surround. No combustible shelves should be positioned on the wall above the appliance. It should

be established that any mirrors or picture frames etc. to be positioned on the wall above the appliance are able to

withstand prolonged exposure to moderate heat and moisture before proceeding with their installation.

The back of the appliance may be installed directly onto a combustible wall, providing it is relatively flat and does not

interfere with the various vent holes in the back panel of the appliance.The wall must be structurally sound and con-

structed from a material capable of withstanding moderate heat. Brick, concrete, finished plaster, most types of con-

ventional wall paper and dry-lined plasterboard are examples of suitable materials. Materials such as flock, blown

vinyl and embossed paper which are sensitive to even small amounts of heat should be avoided as scorching and or

discolouration may occur over time.

If the appliance is to be mounted on a dry lined wall or a timber framed construction wall then the integrity and

ability of the wall to carry the weight of the appliance must be confirmed. It is important in these circumstances that

any vapour control barrier is not damaged, and that any structural members of the house frame are not damaged -

refer to section 7.0.

The appliance must not be positioned vertically within 100 mm (4”) of a carpeted floor, rugs or fabric materials of

any kind. This dimension is measured vertically to the bottom of the appliance firebox.

VENTILATION

A minimum of 100 cm2purpose provided ventilation is required for this appliance.This may be achieved either with

one vent 100 cm2at a high or low position in the room, or split ventilation i.e. 50cm2 be installed at high level and

50cm2 be installed at low level within the room. An openable window or equivalent is also required.The require-

ments of other flued appliance operating in the same room or space must be taken into consideration when assess-

ing ventilation.

4.0

4.1

VENTILATION (continued)

Any ventilation fitted must comply with BS 5871 part 4 and BS 5440 part 2. Ventilation fitted under, or within imme-

diate vicinity of the appliance must not be used as it may adversely effect performance of the ODS system.The appli-

ance MUST NOT be installed in a bedroom, bathroom or any sleeping area. For Republic of Ireland, see relevant

rules in force. The appliance should not be installed within 1 metre of any air vent.

UNPACKING THE APPLIANCE

Remove the outer packaging, remove any instructions or fixing kits.

Read ALL these instructions before continuing to unpack or install this appliance.

If the decorative frame is supplied attached to the firebox, remove the frame by removal of the lower two securing

thumbscrews on either side of the firebox, and then unhook the frame from the top two thumbscrews.

Lift off the remaining packaging components and remove the contents of the box.

GAS SUPPLY ROUTES

There are four possible entry points for the gas supply

pipework to enter the appliance firebox. These entry

points are ‘knock out’ type holes.

Non-concealed gas connections may be made using

the entry points at either end of the firebox or the

one in the bottom of the firebox.A concealed gas con-

nection may be made using the knock out hole in the

centre back of the firebox. Select the most appropriate

entry point and knock out the relevant hole

No more than 1.5m of 8mm diameter pipe must be

used to avoid unnecessary pressure drops.

If a concealed gas connection is to be made, the supply pipe should always be sleeved through walls and floors using

the shortest possible route.

For concealed supply pipe routing, pipes must (where possible) be vertical and providing there is sufficient wall thick-

ness available, they should be placed in pipe chases. Horizontal pipe runs should be avoided. Prior to chasing a solid

wall, an inspection should be made to note the proximity of any cables/sockets outlets which may already be buried.

Pipes must be secured using suitable clips and protected against corrosion. Ideally factory finished protected

pipework and fittings should be used. Joints should be kept to a minimum and compression fittings must not be used.

The pipework installation must be tested for tightness before any protection is applied and/or the pipework and fit-

tings are buried.

FIXING THE APPLIANCE

After having selected the final mounting position of the

appliance, taking into account the site requirements as

specified in section 4 of these instructions, the integrity

of the wall, and the feasibility of the proposed supply

pipe routing, the firebox of appliance may be secured to

the wall.A fitting template is supplied to assist with this.

Mark the positions shown as “Gas model P23G” on the

wall. If the appliance is to be mounted on the inner leaf

of a conventional cavity wall, or a solid wall, drill four

holes using a 6.5mm masonry bit. Insert the fibre

wallplugs provided.

If the appliance is to be mounted on a dry lined wall or

a timber framed construction wall then special cavity

screw fixings will be required which are not supplied

with this product. These should be constructed from

metal and not plastic.

If a concealed gas connection is to be made ensure the gas supply

pipe is in it’s final position and can enter the appliance in the correct

position when the appliance is hung on the wall.

Insert the wall fixing screws into the top wall plugs, taking care to

leave the screws protruding approximately 5mm from the wall. Now

hang the appliance onto these screws through the two keyhole

shaped holes in the back panel of the appliance.

Insert the lower fixing screws into the lower wall plugs through the

corresponding holes in the lower part of the back panel. Do not

tighten fully.

Before tightening the wall mounting screws fully, at this stage it is

recommended to check the horizontal alignment of the appliance

with a spirit level, as small adjustments can still be made if necessary.

When this has been checked, tighten all four fixing screws fully.

To access the upper fixing screws insert a screwdriver either

through the round holes in the front of the outlet grille, or alterna-

tively for easier access the outlet grille may be removed and the fix-

ing screws accessed more directly through the holes in the deflector baffle as shown above.

CHECKING THE BURNER

There are no imitation fuel bed components to install.The appliance features a ribbon burner which is designed to

produce a continuous band of flame over it’s length.

The burner should be visually inspected to ensure it is free from any foreign matter.

If it is necessary to clean or dust off the burner then the glass door should be removed by removal of the four

retaining screws. Re-fit the glass door after cleaning or inspection, ensuring the correct orientation and a good

seal.

TESTING AND COMMISSIONING

Turn on and test the gas supply up to the fire for any leaks, in accordance with the current edition of BS6891.

OPERATING THE APPLIANCE

The pilot is visible behind the left hand side of the burner.

The control knob is located on the lower right hand side of the outer

case. It is of a spherical design and is marked as shown in the diagram

to the right;

Push in and turn the control knob to the SPARK position, and hold

there for a few seconds. Continue turning anti-clockwise through the

spark click to the PILOT light position, ensuring the pilot has lit. If not,

return the knob clockwise, and repeat.

When the pilot lights after the spark, keep the knob depressed for

approximately ten seconds. Now release the knob and the pilot should

stay alight. If the pilot is extinguished during use, wait three minutes

before repeating the ignition procedure.

To achieve the HIGH setting, push the control knob in slightly and con-

tinue turning anti-clockwise to the high position.The main burner should light after a few seconds. To decrease the

setting to LOW, turn the control knob clockwise to the low setting.

To turn to the PILOT position from the HIGH or LOW positions, press the control knob in, and return to the pilot

position and release.To turn the fire OFF, keep the knob pressed in, return to the off position and release.

SPARK FAILURE

The gap between the spark electrode and the pilot should be 3 - 5mm to produce a good spark. There should be

no need to adjust this. If under any circumstances the piezo electric spark fails, the pilot cannot be lit manually.

SETTING PRESSURE

The pressure test point is located on the left hand side of the appliance, on the main burner pipe, next to the brass

restrictor/connector.

Release the setting pressure test point screw, and attach a U gauge. Light the fire on the HIGH setting.

To commission the appliance, the burner pressure must be in accordance with the figures stated in the data section

of these instructions.

The fire is factory set to achieve these pressures and any

significant variation could indicate a supply problem. If the

pressure is too high, the gas supply meter may be set incor-

rectly. This should be checked with the fire running and if

necessary reset by the gas supplier.

If the burner pressure is too low, then check the inlet pres-

sure with the appliance running. If this is less than approx-

imately 20mbar it will need to be reset by the gas supplier.

If the setting pressure is too low, but the meter pressure is

acceptable, then a problem in the supply pipework is to be

suspected.

This will be dirt and debris, kinked or inadequate size pipes,

restriction in a fitting, shut off elbow not fully open or solder flashing across a joint. Identify the cause of the restric-

tion and rectify. Switch the fire off, disconnect the U gauge and refit the test nipple screw. Light the fire and check

for gas soundness.

In the event that the burner pressure is not in accordance with the figures stated in the data section of these instruc-

tions, the appliance must not be commissioned, and the manufacturer should be contacted for guidance.

FITTING THE DECORATIVE FRAME ASSEMBLY

Remove the decorative frame assembly from

any protective packaging, and remove any pro-

tective film that may be present on the frame.

The frame is hung onto the firebox via the two

upper hanging brackets and then secured to

the firebox via the two lower knurled fixing

bolts, which are inserted through the holes in

the lower frame mounting brackets after the

frame is in position. See diagrams to the right

and below.

BRIEFING THE

CUSTOMER

All instructions must be handed to the user for

safekeeping. Show the customer how to light and control the fire.After commissioning the appliance, the customer

should be instructed on the safe use of the appliance and the need for regular servicing. Frequency of service

depends on usage, but MUST be carried out at least once annually. Advise that cleaning of the fire maybe achieved

when the fire is cold using a damp cloth and mild detergent on most surfaces.Advise that the fire will emit a "new-

ness" smell for a time after initial commissioning and that extra ventilation may be needed during this time.

Recommend that a guard be used for the protection of the young, pets, the elderly and the infirm

SERVICING THE BURNER UNIT AND GAS ASSEMBLY

Firstly, remove the decorative frame assembly per the reverse of section 8.4, the glass panel, and disconnect the gas

connection inside appliance.The gas connections to the gas valve can now be released. Detach the burner front cover

plate by removal of the four retaining screws. Undo the four screws retaining the burner support brackets to the

base and rear of the firebox, and remove the control knob and spindle assembly by removal of the spindle retaining

clip.The burner may now be removed.

Remove the pilot and main burner pipes and blow through to dislodge any debris. Now remove the restrictor elbow

and blow through to make sure it is entirely clear.

Unclip the pilot lint gauze and clean with a soft brush. Clean the exterior of the pilot assembly with a soft brush and

blow through the flame ports on the pilot head. Check the aeration holes are free from lint or dirt.The pilot assem-

bly can be removed if required by disconnecting the electrode HT lead, gas pipe and unscrewing the mounting screws

and lifting away.

The pilot assembly is a non-serviceable item and should not be taken apart. Aeration holes must be absolutely clear

internally for proper operation. NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE THE PILOT

STAY ALIGHT. Modifications are dangerous and can have serious unseen effects on safety. If the pilot will not stay

lit there is a problem with dirt, the gas supply to it, or the thermocouple needs replacement.

The gas valve is a non-serviceable item. If this needs replacement, remove M4 securing screw holding the valve in

place, remove all pipe unions, electrode lead, thermocouple lead and then the complete valve. Replacement must be

original manufacturers parts. Re-assemble is the reverse of removal. Ensure setting pressures are as stated in Section

2; Appliance Data.

PILOT ASSEMBLY

Clean the pilot assembly with a soft brush and blow through. Check the aeration holes are free of any dirt or lint.

Clean thoroughly internally, the connection can be removed from the base of the pilot unit using two spanners to

make cleaning easier. Do not damage or try to dismantle the pilot injector.

The unit is factory set and the only check necessary is to ensure the spark gap is correct. See specifications for gas

setting.

NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT. If the pilot will not

stay lit there is a problem with dirt, the gas supply, or the thermocouple needs replacement. Modifications are dan-

gerous and can have a serious unseen effect on safety and therefore MUST not be done. Replacements must be orig-

inal manufacturers parts. Re-assemble is the reverse of removal. Ensure setting pressures are as stated in Section 2;

Appliance Data.

CATA LYS T

It is recommended that the catalyst is inspected for signs of damage and dirt during routine servicing procedures.

The expected life of the catalyst is in excess of 11,000 hours (10 years of normal use).After this time the catalyst

should be replaced.

If there are any deposits of dirt or soot on the catalyst they should be cleaned with a soft brush and a vacuum clean-

er. If removed for cleaning ensure the seal is in good condition before replacing the catalyst.A new seal will usually

be required.

The performance of the catalyst may be checked using a combustion gas analyser as follows.Any analyser used should

conform to BS7927 : 1998 + A1 : 1999.

Ignite the fire as per the operating instructions, and run at maximum setting for 15 minutes. Position gas sample

probe directly over the catalyst via the outlet grille, on top of the appliance. Record the carbon dioxide (CO2) con-

centration and then the carbon monoxide (CO) concentration as displayed by the analyser - also noting the units in

which the values are expressed.

Most analysers display carbon dioxide (CO2) concentrations in percentage (%) terms and carbon monoxide con-

centration in parts per million (ppm) terms. In order to calculate the combustion ratio for the appliance (CO/CO2)

it is first necessary to express both gas concentrations in terms of percentage. To convert from parts per million

(ppm) to a percentage (%) divide the ppm figure by 10,000. Examples : 35ppm = 0.0035%, 15ppm = 0.0015%, 5ppm

= 0.0005%.

10.2

10.3

10.1

CATALYST (continued)

Now divide the concentration of carbon monoxide (CO) expressed in percent by the concentration of carbon diox-

ide (CO2) to obtain the appliance combustion ratio.

The combustion ratio of the gasses emitted by the catalytic convertor should not exceed 0.0015.

If replacing, firstly, remove the decorative fireframe as described in section 8.4.The catalyst is located on the top of

the internal firebox and can be removed be unscrewing the retaining nuts securing the clamping plate. Remove the

catalyst and its seal and discard. Refit a new catalyst and seals in reverse order, ensure the catalyst and door have a

good seals.

TESTING FOR FIREBOX LEAKAGE

Appliances that are several years old or have been extensively dismantled should be checked for soundness. It is

important that all the products of combustion pass through the catalytic converter at the top of the firebox

before leaving the appliance.The firebox is heated by lighting for a few minutes to provide a flow through the fire-

box.The burner is then shut off and a smoke pellet or match introduced at the base of the fire underneath the

burner tray. Large quantities of smoke will emerge from the top of the appliance, but none should emerge from

the joints or gasket faces, especially around the door. It is important to note that the appliance can never be

expected to be 100% smoke tight and small quantities of smoke may be seen in corners of joints and gasket faces

etc without affecting safety when the fire is in operation.

IMPORTANT NOTES

The installation and Servicing of this fire MUST only be carried out by a competent person (such as a CORGI reg-

istered fitter) in accordance with the Gas Safety (Installation and Use) Regulations 1998, the relevant British

Standards, Codes of Practice, the Building Regulations and the manufacturer's instructions.

Failure to comply with the above recommendations could lead to prosecution and invalidate the appliance warranty.

Always keep a note of the installer's name and address, CORGI registration number, the original purchase receipt

and the date of installation for future reference. Failure to produce these documents may invalidate the warranty.

The appliance should be serviced regularly to ensure continued safe operation. See the servicing section for further

reference. Parts of this appliance become naturally hot during use. It is recommended that a suitable fireguard con-

forming to BS 8423 : 2002 is used, especially where young children, pets, the elderly or infirm are concerned.

The manufacturer of this appliance considers all surfaces as working surfaces with the exception of the control knob

and indicator bracket.

Combustible items, such as flooring and furniture and soft wall coverings (such as blown vinyl or embossed paper),

low temperature surrounds etc may discolour if fitted too close to the fire. See relevant section for further details

on clearances to combustibles. No combustible materials or flooring should protrude onto the hearth (if fitted).

This appliance incorporates a combustion monitoring system (ODS).

DO NOT burn any foreign material on this fire. Under no circumstances shall the appliance be used if the glass front

door or panel has been removed, damaged or is open. DO NOT place any objects on top of the appliance, or cover

the outlet grille in any way. DO NOT operate the appliance with any parts removed or missing.

The integral catalysts should be checked by the installer upon servicing to ensure there are no defects or obstruc-

tions that may prevent the satisfactory flow of combustion products.The expected life of the catalyst is in excess of

11,000 hours (10 years of normal use).After this time the catalyst should be replaced.

This appliance is only suitable for the gas type for which it is supplied.

It should be noted that heaters create warm air currents.These currents move heat to wall surfaces next to the

heater. Installing the heater next to vinyl or cloth wall coverings or operating the heater where impurities in the air

(such as tobacco smoke, candle smoke etc.) exist, may discolour walls.

WARNING: Due to the nature of this product the area around the top of the appliance (i.e. the grille) gets very hot.

Care should be taken when operating the appliance.

On first light up of a new appliance, initial curing of high temperature paint and burning off of lubricants may occur

for the first few hours of operation. During this period some smoke may be emitted from outlet grille, this should

be no cause for concern. Accordingly, the room should be well ventilated with all windows and doors open during

this period. During this period the appliance may cause smoke alarms to sound. If this happens, reset the alarms, but

do not remove the batteries.

CLEARANCES TO COMBUSTIBLES

Clearances to non-combustibles

Non combustible surfaces are defined as brick, metal, marble, concrete etc. and also a number of man-made mate-

rials impervious to flame. If in doubt refer to the material manufacturer for further information before proceeding

with installation.

Clearances to the sides of the appliance are 100mm (4”). Clearance to the front of the appliance is 500mm (20”).

The back of the appliance may be installed directly onto a non-combustible wall, providing the area behind the appli-

ance is flat and does not interfere with the various vent holes in the back panel of the appliance.

A non combustible shelf of any depth may be positioned above the appliance provided it is no closer than 400mm

from the top of the appliance glass panel and the wall above the appliance is non combustible.

The appliance must not be positioned vertically within 60mm ( 2.4”) of a solid floor (i.e. wood or stone) or hearth.

This dimension is measured vertically to the bottom of the appliance firebox.

Clearances to combustible materials

Combustible materials are defined as wood, fabrics, or other materials likely to combust if exposed to flame.

Generally, any material, which is likely to discolour, melt or misshape when exposed to moderate heat, should be

considered as a combustible material or surface.

Clearance to the sides of the appliance are 100mm (4”) but curtains, drapes and other fabrics are not permitted

within a distance of 500mm(20in) of the appliance sides. No such materials are permitted directly above the appli-

ance regardless of distance.

The minimum clearance to the ceiling above the appliance is 800mm (31.5”) measured from the top of the appliance

glass panel. Combustible materials should not be positioned directly in front of the appliance within a distance of

one metre.
