The Flame System 2 has a single aerated burner, the design of which produces a ribbon of flame which runs across the front
of the fire bed. A single gas control combined with piezo ig niter selects ignition (pilot only) and can be turned anticlockwise
to select a high rate and then a reduced input at the maximum rotation. For extra safety the control is designed so that gas
cannot be allowed to reach the burner until pilot ignition has been proven.
A Flame Supervision Device (FSD) is fitted. This ensures that if the pilot goes out for any reason (including being turned
off), the gas flow to the burner is cut off until the full lighting procedure is repeated. The oxy-pilot or O.D.S. will cause the
appliance to ‘shut off’ in the event of continued spillage occurring under hazardous or blocked flue conditions. The burner
assembly is fixed to the base of the radiant box which also includes a fire back made of ceramic fibre, this forms an
insulating surface to reflect heat into the fire bed, raising its temperature and increasing the amount of heat radiated into the
room. A decorative trim completes the front face of the appliance.
There are various types of front and fret available for this appliance; these have perforated frets to allow air to be entrained
into the fire bed to ensure clean combustion. The optional fire fronts and frets are listed with your supplier. If other Fronts
and Frets are to be used they must have a minimum open area in the fret of 20 square centimetres and 60 square centimetres
in the Front, as shown in figure 11.

The Flame System 2 is a decorative fuel effect appliance designed and manufactured to the requirements of the British
Standards Institution BS 5258 Part 12: 1990 and EN509. It is for use on Natural Gas only
.
All gas appliance installations must be installed by a competent person in accordance with the current Gas Safety
(Installation and Use) Regulations or the rules in force and in accordance with the attached Installation Instructions;
failure to do so could lead to prosecution.
The appliance is fitted with an ODS, a spillage monitoring system which operates if the evacuation of products is
interrupted (i.e. blocked or incorrect flueing). If the gas fire repeatedly ‘goes out’ it may indicate a problem and the
installer or specialist should be informed before further use.
Areas of this appliance will become hot after prolonged running and it is recommended that for the protection of the very
young, elderly and infirm a fireg uard conforming to BS 6539 or BS 6778 be used.
Care should be taken to prevent any damage being caused to surrounding soft furnishings or decor e.g. many embossed vinyl
wall coverings may become discoloured if located too close to the appliance. Clearances required for combustible shelves
are shown on page 3.
This product uses fuel effect pieces, gaskets and insulation material containing Refractory Ceramic Fibre (RCF), which
are man-made vitreous silicate fibres. Excessive exposure to these materials may cause temporary irritation to eyes, skin
and respiratory tract, consequently, it makes sense to take care when handling these articles to ensure that the release of
dust is kept to a minimum.
It is recommended that the chimney or flue should be swept annually by a com petent person and the appliance check ed for
spillage (smoke test) and that there are no excessive deposits of soot.
The curing effect of heating the coals will cause an initial odour which, although not harmful, may require additional
ventilation until the odour has disappeared. This appliance will run on Full for approximately 4.4 hours on one therm of
gas.

Depress the gas control slightly and turn anti-clockwise until the indictor mark is aligned with the letters LOW. The
burner will now be at minimum rate.
6. To turn the appliance ‘off’, return the control to the ‘OFF’ position.
7. If for any reason the fire cuts out, return the control knob to the `OFF’ position and wait 3 minutes before relighting.
8. In the event of failure of the igniter the fire may be lit by placing a lighted taper or match at the pilot position at the
same time depressing the gas control in the IGN position.

Debris from any source or any soot formed shall require removal. Allow the appliance to cool for two to three hours
before removing all of the coals and ceramic blocks for cleaning purposes. Once all the ceramics are removed from the
fire bed check that no debris is located in the burner slots. If any debris is present it may easily be removed by using a
small piece of thin cardboard to ease out any foreign matter. Be sure to remove the cardboard after use. Cleaning should
be carried out in a well-ventilated area or in the open air, by gently brushing with the pieces held away from your face so
that you avoid inhaling the dust. We do not recommend the use of a normal domestic vacuum cleaner, which may blow
dust back into the air.

The gas connection to this appliance is made with 8mm O/D rigid or semi rigid tube to a combined pressure
test/restrictor elbow situated on the right-hand side of the burner as shown in Fig 1. Any pipe used under the tray
must be rigid tube such as bundy, a length is supplied for the convenience of the installer. Provision is made in the
rear of the box to make a concealed connection; (additional holes may be drilled as required). The installer is
reminded of the requirements of BS 6891 1988 dealing with enclosed pipes. The standard requires that when a gas
pipe is fed through a wall, the pipe should be enclosed in a tight sleeve to protect against failure caused by
movement and shall be constructed to prevent a passage of gas either between the pipe and sleeve or sleeve and the
wall. If a gas supply is required to be fed from either the left or right across the front of the appliance it should be
routed as shown in Fig 2. It is only the MACH II Front & Fret that has provision for this requirement alternative
Fronts & Frets will need modifying to allow access for the supply tube, see Fig 4.

A Pressure Test Point at the inlet elbow enables verification of the inlet pressure of the appliance under operating
conditions and can also be used to check the gas soundness of the connections to the appliance gas control. To
check the joints of the burner assembly for gas soundness it will be necessary to carry out the examination prior to
installing into the case. If a manometer is used care must be taken to ensure that it is not disconnected with the gas
turned on and the fuel bed hot.
