1 INSTRUCTIONS FOR USE
1.1 INTRODUCTION
Congratulations on your purchase of this modern BARBAS gas fi re. This quality
product will provide you with many years of enjoyment due to the fl ame effect
and warmth that it provides. Please read the instructions for use carefully before
using the appliance for the fi rst time. Keep this booklet in a safe place.
1.2 BUILT-IN PROTECTION OF THE APPLIANCE
The appliance is fully protected by means of a thermo-electric pilot light shut off
in the event of a gas escape from the main burner. Additionally, the gas fi re is
fi tted with a thermal one-way protection safety system. This system shuts off the
appliance if the fl ue gas is not exhausted.
1.2.1 Safety
Do not place any embers, vermiculite granules or logs against
the pilot light burner. Make sure that the pilot fl ame can burn at
all times freely over the main burner. Only in this way is proper
ignition of the main burner ensured.
Ignoring these directions could lead to a dangerous situation.
It is essential that the appliance, the chimney and the burner
air intake are cleaned and inspected annually by a
recognised fi tter/gas specialist. The safe operation of the
appliance will thus remain guaranteed.
See for additional instructions Chapter 3: Maintenance.
If the pilot fl ame goes out for any reason, wait for 5 minutes
before attempting to re-light it.
The gas fi re must never be used with the door open or the
door glass removed.
Never place fl ammable material on the ceramic log set.

UNICA 70UNICA 100 UNICA 65
UNICA 52
UNICA 50
The fi lling of the main burner with embers, vermiculite granules
and wood logs may not under any circumstances be changed
or added to.
Do not place easily-fl ammable materials, such as nylon clothing
or fl ammable liquids, in the vicinity of the gas fi re.
Ensure at all times that children and other people who are not
aware of the operation of the gas appliance are only in the
vicinity of the appliance exclusively under supervision.
Use a fi reguard to protect children and other persons
mentioned above against possible burns.
1.3 OPERATION : HAND CONTROL
The gas regulating block, with which the fi re is operated, is located behind the
operating hatch. The fi re has one main burner which can be operated by the
thermostatic knob and/or the sliding knob.
The thermostatic knob is used to choose the correct setting and the modulating
thermostat ensures that the set temperature (13 - 38°C) is maintained.
The slider, is used to select the desired position, the burner will now
continueously burn as an atmospheric burner until the setting is changed.
Both operating knobs can be used in combination.
The Unica 65, Unica 70 and Unica 100 are fi tted with a double convection fan as
standard. For the Unica 50 and Unica 52 is this an option (factory-done). The
fan speed can be regulated with the knob located on the right-hand side of the
gas regulating block. The knob on the Unica 52 and 65 can be found by opening
the operating hatch on the right hand side.
When the appliance reaches a temperature of 40°C, the convection fan will
automatically be activated. After the appliance has been switched off, the fan
will continue until the temperature has fallen below 35°C.

1.8 USING THE APPLIANCE FOR THE FIRST TIME
The gas fi re is coated with a lacquer layer resistant to high temperature.
During the fi rst hours of operation, the burning in of the lacquer may result in
an unpleasant smell. This is harmless, however. Operating the gas fi re at full
capacity for a few hours, while ventilating the room, will eliminate the smell.
Moreover, deposits may form on the inside off the glass; these can be removed
with a dry cloth when the gas fi re has cooled down.
1.9 DAILY MAINTENANCE
l Regulary check that the air supply is still open.
l Ensure that as little dust, and as few particles of cigarette smoke, candles and
oil lamps as possible pollute the air in the room in which the appliance is used.
Heating of these particles by the convection system of the appliance could
lead to discoloration of the walls and ceiling. It is therefore very important to
ensure that the room in which the appliance is located is suffi ciently ventilated.
Regularly remove any dust deposits from behind the control fl ap by means of
a vacuum cleaner.
Important: If the glass is broken or cracked, it must be
immediately replaced before operating the
gas fi re again.
l If anything is spilt on the fi re, switch it off immediately and wait for it to cool
down suffi ciently before cleaning. Never use scouring powder, aggressive
cleaners or fi re polish on the gas fi re. Use only a dry lint free cloth.
l Barbas heat resistant lacquer in aerosols can be obtained from your
distributor. During the yearly maintenance, the lacquer can be used to repair
small areas of damage.
IMPORTANT
The installation must only be carried out by a
CORGI registered installation engineer.

Unica 65 inner shell by, fi rst of all, fi tting loosely the 4 insert nuts, so that
the inner shell is completely level against the front of the outer
casing.
Next, adjust the inner shell by means of adjustment bolts which
are located on the bottom left and right of the combustion
chamber.
The fl ue spigot of the inner shell has to be tightly fi tted against
the top side of the outer casing. Tighten all 4 insert nuts
securely.
CHECK THAT THE SEALING CORD OF THE FLUE SPIGOT IS CORRECTLY
CONNECTED !
3. FITTING THE “CONTROL UNIT”
First of all, make the elctrical connection (when dismantled) on the connector on
the right-hand side. (Only applicable if the appliance is provided with a
convection fan.) While sliding the “control unit” underneath the inner shell,
secure the (light blue) plug connectors of the security system. For this purpose,
the wires need to be led outside, left along the inner shell, after which the plugs
have to be pushed on the thermocouple interrupter near the gas regulating
block. The “control unit” must be pushed into the inner shell as far as it will go.
Fit the thermostat sensor by means of the clip to the bottom plate.
Use 4 bolts to secure the “control unit” together with the glass support plate.
4. GAS AND ELECTRICAL CONNECTION
Use the supplied swivel to make the gas connection. Ensure that the gas
regulating block stays straight during the connection. Ensure that the gas
regulating block and pipework are not put under stress.

The mains electricity can now be restored to the wall socket.
(Only applicable if the appliance is provided with a convection fan.)
Check that all connections are completely gas tight using soapy water or a leak
tester. As a check, allow the fi re to burn briefl y (maximum 1 minute).
Following verifi cation that there are no leaks, fi nish off building in the fi re insert.
(See Chapter 1; Instructions for use.)
5 POSITIONING THE CERAMIC LOG SET
The appliance is delivered with a set of artifi cial wooden logs and vermiculite
(and/or embers: Unica 50 and Unica 100).
Important: • Do not place any vermiculite granules, embers or
logs against the pilot light burner. Make sure that
the pilot fl ame can burn at all times freely over the
main burner. Only in this way is proper ignition of
the main burner ensured.
• The burner bed (with embers and/or vermiculite
granules) and the positioning of the logs must
not be changed.
• Ignoring these directions could lead to a dangerous
situation.

3 MAINTENANCE
3.1 ANNUAL MAINTENANCE
It is essential that the appliance, the chimney and the
burner air intake are cleaned and inspected annually
by a recognised fi tter/gas specialist.
The safe operation of the appliance will thus remain
guaranteed.
Maintenance consists of the following:
l Remove fi rst the embers and/or vermiculite granules and set of logs from the
main burner and carefully clean these with a soft brush.
l Clean and inspect (visually) the main burner(s), pilot light, combustion
chamber, fl ue system and combustion air intake. Dust can be removed using
a vacuum cleaner.
l After cleaning;
Carefully replace the embers and/or vermiculite granules and set of logs on
and around the main burner according to the installation directions in this
instruction booklet.
Do not place any embers, vermiculite granules or logs against the pilot
light burner. Make sure that the pilot fl ame can burn at all times freely
over the main burner. Only in this way is proper ignition of the main
burner ensured.
Ignoring these directions could lead to a dangerous situation.
l Check the gas supply and fl ue pipe/chimney for any leaks.
l Check the correct operation of the gas regulation block, thermocouple circuit
and the ignition of the main burner.
l Check the gas inlet-pressure (both when the appliance is off and when it
burns at maximum) and the burner pressure.
l Check the complete fl ue pipe/chimney, including the outlet on the roof.
l Check the operation of the thermostatically controlled convection fans.
(if present.)
l Check the operation of the thermal one-way protection safety system.
37
UNICA 70 UNICA 100UNICA 65UNICA 50 UNICA 52
4 FAULTS
Possible reasons for the gas fi re going out are:
l Operation of the thermal one-way protection safety system due to fl ue gas
escape.
l Malfunction of the thermal one-way protection safety system.
Check by means of testing.
l Insuffi cient gas pressure.
l Pilot light is dirty.
l Thermocouple voltage too low. This is usually caused by insuffi cient heating
at the tip of the thermocouple by the pilot light.
l Dirty electrical contacts in the thermo-electric system, wiring and
connections of the thermal one-way protection safety system.
