The ENIGMA II LIDE incorporates a single gas control, which selects ignition pilot, and main
burner low and high settings.
The ENIGMA II LIDE incorporates a safety device in the form of an Oxygen Depletion ystem,
which constantly monitors the oxygen in the room and will cause the fire to switch off if the
oxygen level reduces, for instance due to insufficient ventilation or a blocked flue.
If this repeatedly occurs do not attempt to relight the appliance until a qualified engineer has
checked it, the problem may not be due to lack of air or a defective flue.
Warning:-This appliance has a naked flame, has with all such fires it is essential that a
fireguard should be used for the protection of children, the elderly and infirm. Fireguards should
conform to B 6539 (1984) (Fireguards for use with solid fuel appliances).
During the normal operation of the fire some black staining may appear on some parts of the
fuel bed. This is quite normal and adds to the appearance of the appliance. However, if
excessive black staining does occur it may be due to the fuel bed being incorrectly laid. This
should be checked prior to contacting a service engineer.
SECT ON TWO Operation
The full lighting procedure is as follows: -
a. Push slide control lever down, as far as possible a clicking noise will be heard and the
pilot will light, HOLD DOWN FIRMLY FOR ABOUT 20 ECOND .
b. Allow the lever to spring up the pilot light should remain alight and the main burner
should light on its low setting.
c. hould the pilot fail to light, pull the lever fully up to turn off the appliance, wait 3 minutes
and repeat the procedure (a &b). If the pilot does not light and no clicking noise is heard
replace the battery and try again.
d. After lighting the pilot flame and the main burner on its low setting the control lever may
be lifted until slight resistance is felt, this will put the burner on its high setting.
e. To completely extinguish the fire, pull the lever up past the resistance to its fullest extent.
f. The fire may be operated on either its low or high setting.
g. It is recommended that the appliance is operated on its high setting for a short period
before adjusting to the low setting.
h. If the ignition does not operate fit a new 9V battery (PP3/MN1602) to the ignition unit,
located behind the fret adjacent to the gas inlet pipe, and repeat ignition procedure prior
to reporting a fault.
Note: - If the ignition fails the pilot can be lit with a taper or a match held at the pilot head.
