Important Safety Advice
When using electrical appliances, basic precautions should
always be followed to reduce the risk of fire, electrical shock,
and injury to persons, including the following:
If the appliance is damaged, check with the supplier before
installation and operation.
Leave the appliance disconnected from the supply voltage until
it is commissioned.
Do not use this heater in the immediate surroundings of a bath,
shower or swimming pool.
Do not locate the heater immediately below a fixed socket outlet
or connection box.
Do not cover or obstruct in any way the heat outlet grille located
at the top of the heater or the heat outlet at the base of the
heater. Overheating will result if the heater is accidentally
covered.
This appliance is not intended for use by children or other
persons without assistance or supervision if their physical,
sensory or mental capabilities prevent them from using it safely.
Children should be supervised to ensure that they do not play
with the appliance.
In the event of a fault unplug the heater.
Unplug the heater when not required for long periods.
Ensure that furniture, curtains or other combustible material
are positioned no closer than 1 metre from the heater.
Although this heater complies with safety standards, we do not
recommend its use on deep pile carpets or on long hair type of
rugs.
The appliance must be positioned so that the plug is accessible.
If the supply cord is damaged it must be replaced by the
manufacturer or service agent or a similarly qualified person in
order to avoid a hazard.
General
This fire incorporates a flame effect that can be used without heating,
so that the comforting effect may be enjoyed at any time of the year.
The flame effect is provided by a low wattage motor and two 60 watt
lamps. Using the flame effect on it’s own, therefore, requires little
electricity.
The fan assisted hot water convector heater (heat exchanger) is located
at the base of the fire. A separate 2kW electric heating unit is concealed
behind the top grill. The electric heating unit can be used separately
from the heat exchanger as an individual heat supply when the central
heating system is not on. It may also be used as a heat boost when
using the heat exchanger (central heating system on).
Heat Exchanger
The Mirage Log Stove may be fitted in place of or in addition to existing
radiators. Using the hot water from the central heating system and a
powerful electric fan it will produce up to 2.0kW of heat into the room.
The heat output from the heat exchanger unit may be adjusted by means
of a variable speed fan.
Electrical
WARNING – THIS APPLIANCE MUST BE EARTHED
This heater must be used on an AC ~ supply only and the voltage marked
on the heater must correspond to the supply voltage.
Before switching on, please read the safety warnings and operating
instructions.
For your convenience, the heater is fitted with a rewireable plug
incorporating a 13 amp fuse. In the event of replacing the fuse in the
plug supplied, a 13 amp fuse approved by ASTA to BS1362 must be
used.
Central Heating System Design
1. When fitting the Mirage Log on to a central heating system check
that the boiler is capable of delivering the extra heat into the
appliance by re-sizing the system. The Mirage Log will add under
ideal conditions 2.0kW (6,800 Btu/hr) onto the boiler sizing.
2. Due to the low water content of the heat exchanger in the Mirage
Log compared to a panel radiator in the system, an adequate flow
of water should be maintained to compensate for rapid cooling of
the water as it passes through the exchanger i.e. maximum
efficiency is gained if the Mirage Log is placed as near to the central
heating pump as possible to give the maximum pressure head
across the appliance.
3. To prevent cold air from being blown into the room a low limit
thermostat is fitted which prevents the fan starting until hot water
reaches the heat exchanger. This principle must be explained to
the user to prevent any confusion arising over the appliance’s
operation.
Installation
Ensure that all packing items are removed (read any warning labels
carefully).
Retain the packaging for possible future use, in the event of moving or
returning the fire to your supplier.
The Mirage Log is designed either;
1. To be installed into an inset cavity. When installing into an inset
cavity, ensure that there is an adequate unobstructed air intake
available to the air inlet slots located at the back of the appliance.
Both the heat exchanger fan and the electric heater fan require an
adequate supply of air for their effecient operation.
2. To be floor mounted, preferably on a hearth. For stability, keyhole
slots are provided in the back panel for wall fixing.
The appliance should not be placed where it could be moved or knocked
by doors etc. If installing the appliance into an inset cavity, or if using a
fire surround in conjunction with the Mirage, the minimum clearance
dimensions shown in Fig. 1 must be observed.
The wall mounting dimensions are shown in Fig. 2.
Note: The switch ‘a’ in Fig. 2 is for factory test purposes only and access
is not required after installation.
Water connections
WARNING : Do not connect to electricity supply when making water
connections.
The appliance terminates in 10mm pipe tails (top pipe for return - see ‘b’
in Fig. 4 and bottom pipe for flow - see ‘c’ in Fig. 4) and reducers will be
required to fit to 15mm pipe etc. The use of ‘Nevacock’ ball valves or
other types of gate valve is recommended at the flow and return
connections to the heat exchanger. This will allow the appliance to be
isolated or removed for servicing or re-siting.
To remove the surround , first remove 8 outer screws from surround
and 6 screws from inside door (see Fig. 3) and place carefully aside.
Gently lift the surround from the chassis.
After connecting the appliance to the heating circuit refill the system (if
required) and bleed the air out of the heat exchanger using the bleed
screw provided (located on top of return pipe - see ‘a’ in Fig. 4). If any
water escapes from the bleed screw ensure that it does not fall onto any
electrical wiring or connections. After bleeding the appliance ensure
that electrical controls are completely dry before connecting to the supply.
Commissioning the Heat Exchanger
Ensure that the central heating is OFF and that the heat exchanger
is COLD.
1. Check the appliance for water leaks at any connection, bleed screw
etc. Ensure the electrical circuit is free from water.
2. Replace the surround and screw (14 screws) fix to chassis.
3. Turn ON electricity supply.
4. Press ‘Switch 1’ to ’ ’. The flame effect should now operate - see
Fig. 7.
5. Press ‘Switch 4’ to the large Fan symbol. The fan should not start
due to the low limit thermostat.
7. Turn ON the central heating system.
8. As hot water reaches the heat exchanger the low limit thermostat
should cut in and the fan will start to operate (set at 38oC).
9. Use ‘Switch 4’ to adjust the fan speed.
10. If the Mirage fails to operate as detailed in the above sequence
contact Customer Services for further assistance.

Insufficient heat output from heat exchanger may be
caused by:
•Airlock in heat exchanger - (ISOLATE FROM ELECTRICAL
SUPPLY). Remove the case and bleed the appliance as outlined
in the ‘Water Connections’.
•Hot water temperature too low - the boiler thermostat may need
increasing.
•Bulk of the water circulating through the radiators - rebalance
by closing back lockshield valves on radiators to increase water
flow through the Mirage Log.
•Dirty heat exchanger.
Operation
With the fire in position the controls are located on the upper right-hand
side of the appliance.
Flame Effect
Press ‘Switch 1’ to ’ ’. The flame effect should now operate - see
Fig. 7.
Electric Heating Unit
You have a choice of low heat (1.0kW) or high heat (2.0kW) output. In
order to operate the fan heater, ‘Switch 1’ must be switched on.
Low heat setting
Press ‘Switch 2‘ to ‘I’ and ‘Switch 1‘ to ‘ ’ position. The flame effect will
remain on and you will have selected the low heat setting.
High heat setting
Press ‘Switch 3‘ to ‘II’ and ‘Switch 2‘ to ‘I’ and ‘Switch 1‘ to ‘ ’ position.
The flame effect and low heat setting will remain on and you will have
selected the high heat setting.
Setting the Thermostat
Plug in and with Switches 1, 2 and 3 on, turn the thermostat knob to
MAX to warm the room rapidly. When the room temperature has reached
the desired level, turn the thermostat knob back slowly until the
thermostat just clicks off. The heater will then maintain the room
temperature at the chosen level.
NOTE – Should your heater fail to come on when the thermostat is at a
low setting, this may be due to the room temperature being higher than
the thermostat setting.
Safety cut-out
For your safety, this appliance has been fitted with a thermal cut-out. In
the event that the product overheats, the cut-out switches the heat off
automatically.
To bring the heat back into operation, remove the cause of the
overheating, then unplug or turn off the electrical supply to the heater
for up to 10 minutes.
When the heater has cooled sufficiently, re-connect and switch on the
heater.
Heat Exchanger Unit
To operate the heat exchanger follow the instructions previously
described in ‘Commissioning the Heat Exchanger’.
To vary the heat output from the heat exchanger, use the fan speed
control knob to increase or decrease the speed of the fan.
Note: Both heat sources (electric heater and heat exchanger) can
be operational at the same time.
Maintenance
WARNING – ALWAYS DISCONNECT FROM THE POWER SUPPLY
BEFORE ATTEMPTING ANY MAINTENANCE.
Lamp Replacement
To gain access to the lamps;
1. Open the door.
2. Remove the two screws on the fuel effect - see ‘x’ in Fig. 5.
3. Slide the fuel effect out and set aside carefully (taking care not
to damage the logs as they are fragile).
4. For access to the bulbs, carefully rotate the flexible rotisserie
out of position ensuring that the rubber grommet is not lost –
see ‘y’ in Fig. 6.
5. Refit the rotisserie making sure that the rubber grommet is
carefully pushed into the slotted hole on the axial bracket - see
Fig. 6.
6. Unscrew the defective lamp as indicated. Replace with a 60W
E14 SES lamp, do not over tighten - see Fig. 6.
7. Refit the fuel effect with the two screws.
Cleaning
Before commencing cleaning, unplug the heater and allow it to cool.
The surfaces of the heater should be given an occasional wipe over
with a soft damp cloth. Do not use detergents, abrasive cleaning powder
or polish on the body of the heater.
The viewing screens should be cleaned carefully with a chamois leather.
DO NOT use proprietory glass cleaners.
To remove any accumulation of dust or fluff the soft brush attachment of
a vacuum cleaner should occasionally be used to clean the outlet grille
of the fan heater.
