INTRODUCTION
The ENIGMA II SLIMLINE incorporates a sin le as control, which selects i nition pilot, low or
hi h settin s. It is operated via a control knob located behind the ash pan cover.
The appliance incorporates a safety device in the form of an Oxy en Depletion System, which
constantly monitors the oxy en in the room and will cause the fire to switch off if the oxy en
level reduces, for instance due to insufficient ventilation or a blocked flue.
If this re ularly occurs do not attempt to reli ht the appliance until a qualified en ineer has
checked it, the problem may not be due to lack of air or a defective flue.
The pilot can be left on or the pilot can be extin uished and relit each time the fire is used.
A fire front (fret) must be used with this appliance.
SECTION TWO Operating the Appliance
The appliance Control Knob is positioned behind the ash tray cover.
The full li htin procedure for the appliance is as follows: -
a. Remove ash pan cover.
b. Push knob in as far as possible on as control.
c. Turn knob anti-clockwise until a click is heard. The knob will stop at the position marked
' '
and a flash should be seen at the left-hand side of the burner. At the same time the pilot
flame should li ht. KEEP THE KNOB PRESSED IN FOR 20 SECONDS. Should the pilot
fail to li ht, turn the control knob clockwise to the
' '
position, and repeat the procedure.
d. After li htin the pilot flame the control knob should be allowed to sprin out sli htly. This
will allow you to turn the knob further anti-clockwise to the position marked
' '
. The pilot
flame should then i nite the main burner.
e. It is possible to adjust the hei ht of the flames by turnin the control knob between the
positions marked
' '
and
' '
. Note that the knob 'latches' in position at either end of this
movement and must be pushed in sli htly before it can be turned.
f. To turn the burner off, depress the knob sli htly and turn it to the
' '
position.
. To completely extin uish the fire, depress the knob sli htly and turn to
' '
the position.
h. Replace ash pan cover.
N te: - If the i nition fails the pilot can be lit with a taper or a match held at the pilot head.
Remove fret for access and replace after li htin .

to provide trouble-free operation.
It is important that: -
• The chimney or flue is checked annually to ensure clearance of combustion products.
• The fire does not normally require purpose-built ventilation but if for any special reason
purpose-built ventilation is provided it should be checked periodically to ensure freedom from
obstruction.
• Any debris from the chimney or flue should be removed. The fire should be allowed to cool
for three to four hours before it is removed.
• Rubbish must not be thrown onto the coal bed under any circumstances.
• The cast fire front must be positioned in front of the fire whilst it is burnin

Spacers are available in the followin sizes 42mm, 30mm and 20mm these may be used to
reduce the minimum depth required.
The fire can be installed in the followin flues and locations: -
CLASS ONE
A conventional brick or stone chimney, with
the builder's openin constructed of non-
combustible material as used for a solid fuel
appliance, with a minimum effective cross-
sectional dimension of 225 x 225 mm (9 x 9
ins) or a lined flue (e. . clay, metal etc.) with a
minimum diameter of 125 mm (5 ins), with a
minimum effective overall hei ht of 3 metres
(10 ft). A builder's openin a minimum of 550
mm hi h (or 500mm with Low lintel version)
and 350 mm wide with a minimum depth of
170mm (or 140mm if flue has never been
used for solid fuel) to allow sufficient volume
for debris collection.
Any permanent flue restriction or variable dampers shall be removed or locked fully open. The
chimney should be swept prior to installation if not new or previously used with a as appliance.
IMPORTANT: - The restrict r plate is pre-fitted f r installing the appliance int 150mm
(6”) diameter flue r larger. Bend d wn the restrict r plate if the appliance is installed
int a 125mm (5”) diameter flue r pre-cast flues.
CLASS TWO
Pre-cast
A pre-cast flue correctly constructed conformin to the requirements of BS 1289: 1975, 1986 or
1989 with a minimum effective overall hei ht of 3 metres (10 ft) which is correctly terminated
(see BS 5440). It will normally require an
additional thickness of 25mm in the form of a
fireplace back panel or if it is intended to be
fitted back to the plaster line then a spacer
may be required to meet with the minimum
depth requirement.
IMPORTANT: - D n t fit the restrict r
plate if the appliance is installed int this
type f flue.
Note: An inspection should be made to
ensure that the internal walls of the flue are
clear of mortar fan s. It is recommended that
the plasterwork should not be directly bonded to the surface of the flue blocks, ensurin that
there is a small air ap between the flue blocks and the wall surface. The fire can be installed
with the plasterwork bein directly bonded to the flue blocks but there is a risk of surface
crackin occurrin to the plaster above the appliance.
