1.3 First firing
Your fireplace is coated with heat-resistant enamel that can withstand extremely high temperatures. Burn the
fire at high during the first hours of use and ventilate the room well. The curing of the enamel may produce a
smell/smoke, but this is harmless, however. Any marks on the glass can be removed immediately with glass
cleaner.
1.4 Guarantee ( see page 13 and 14)
Always complete your guarantee card in full and return it to your supplier immediately after purchase. Type
and serial number are shown on the plate that you will find on the bottom of the burner unit.
2. OPERATING INSTRUCTIONS VERSA
The Versa has a combined glow-effect and main burner (see page 10 figure 4). This burner can be operated
with either the thermostat knob (A) or the manual slide (B). You select the required setting with the thermo-
stat knob (A) and the modulating thermostat provides the right temperature. The hand-operated slide (B) al-
lows you to select the flame height you wish and the burner will continue to burn at that setting until you
change the selected setting.
2.1 Igniting.
* Open the gas stopcock fitted in the gas pipe to the appliance.
* Ensure that the thermostat knob (A) is at position nin the initial setting.
* Turn the thermostat knob (A) to the ignition position.ô
* Push the thermostat knob (A) and keep it pushed in.
* Push the ignition knob (C) all the way in until you hear a “click”; this is the spark ignition.
* Youcan see through the glass window whether the pilot light is burning. “Click” a few more
times if necessary, until the pilot light ignites.
* Keep the thermostat knob (A) pushed in for about another 30 seconds when the pilot light starts
burning and thenrelease the knob.
* If the pilot light does not continue to burn, wait 5 minutes and then repeat the procedure.
* The burner is ignited by turning the thermostat knob (A) to the required setting (between set
tings 1 and 7, depending on the required temperature).
* To ignite the appliance with the glow-effect burner, move the slide (B) from position ndepend-
ing on the required flame height (see figure). The glow-effect burner only functions when the
thermostat knob is between positions 1 and 7 (position 1 = low, position 7 = high).
Remark
Position (1) on the thermostat knob (A) is the pilot light setting if the room temperature is 10°C or more. If
the room temperature is below 10°C, the burner will also start to burn in position (1) until the temperature
has risen to 10°C.

Page.4
Warning
If the pilot light goes out, you must wait at least 5 minutes before lighting the appliance again.
2.2 Operation of thermostat
The modulating thermostat ensures that the temperature selected with the thermostat knob (A) is precisely
maintained. If you set the thermostat knob (A), the burner will start burning at full power first of all, but will
then start to burn lower and find a stable setting. If the room temperature falls, the burner will start burning
higher until the correct temperature has been regained. This is regulated automatically by the thermostat.
2.3 Operation of glow-effect burner
The glow-effect burner will only start to burn if you open the slide (B) and only works if the thermostat knob
is set between positions 1 and 7. The required flame height has a continuously variable adjustment.
2.4 Operation of fan (only applies to HV model)
This fire is fitted with a fan system for fast heat emission. The fan comes into operation automatically if a
temperature of 60°C is reached in the fireplace. The fire is also fitted with a two-way switch (see page 10 fig-
ure 4-D) with which to regulate the rotational speed of the fan. Setting 1 = low speed and setting 2 = high
speed. If you switch the fire off, the fan will turn itself off in due course. Never use the fire if it is not possi-
ble for the fan to operate (the plug must always be in the socket therefore!).
2.5 Switching off the fire
* To turn the stove off completely, turn the thermostat knob to position ?. The pilot light will then go
out. We recommend, however, that you allow the appliance to continue burning on the pilot light dur-
ing periods when the appliance is being used.
* If the stove is out of use for a longer period, then it is also wise to shut off the gas stopcock in the sup
ply pipe.
2.6 Maintenance
* The stove can be cleaned with a soft damp cloth. The appliance should be turned off immediately if
some thing is spilled on it and the marks can be removed with soft soap suds once the stove has cooled
down. Never use an abrasive!!!
* Any deposit on the glass can be removed with glass cleaner.
* It is advisable to have the stove and the chimney checked and cleaned by an installer before every heat-
ing season. If the special glass is broken or cracked, have it replaced at once, before you turn the stove
on again.
Warning
Gas stoves become hot when they are in use. Care must be taken therefore and children and invalids, for ex-
ample, should be kept away from burning stoves. Stoves must also never be installed on or against combusti-
ble materials (curtains etc.).
3. OUTLET SAFETY (T.T.B) (See page 9 figs. 2-4)
Purpose:
The appliance is fitted with a thermaloutlet safety or T.T.B. (thermal draught protection), which switches off
the pilot light and the burner as well, therefore, if there is a leak of combustion gases out of the draught lim-
iter. The outlet safety must never be rendered inoperative.
Operation:
The detection device is a thermostat that opens an electrical contact when a certain temperature is exceeded,
thereby interrupting the thermocouple current. This causes the control block to switch off the gas supply to
the main burner and pilot light burner. The appliance can be ignited again after waiting 5 minutes for the de-
tection device to cool down.

Page.5
If the appliance again switches off due to the intervention of the outlet safety, you should have the outlet sys-
tem (chimney) inspected by a registered installer. This safety device must not be rendered inoperative or al-
tered, because the system will not function properly otherwise. Only original ThermoCet components must
be used for replacement. This also applies to the fastening materials and wiring.
Possible causes of the intervention of the outlet safety are:
* A poor connection between the fire and the chimney.
* The chimney is completely or partially blocked by fallen debris etc.
* The draught is inadequate.
* Negative pressure in the room as a result of an extractor hood or central extraction system which is too
strong.
Consult your installer if this situation arises!
4. ELECTRICAL INSTALLATION INSTRUCTIONS ( only for Versa HV )
The appliance is fitted with a fan and must be connected to an earthed 230VAC/50Hz wall socket. Installa-
tion must be in accordance with NEN 1010 and local regulations. Always ensure that the wall socket is still
easily accessible after the appliance has been installed.
Technical specifications fan: 230V, 50Hz Power 25 w
Only original ThermoCet components must be used for replacement.
5. GAS INSTALLATION INSTRUCTIONS
5.1 General instructions
* The appliance should only be installed and connected by a registered installer in accordance with the
local Gas Appliance Regulations.
* The Versa HV is fitted with a fan and must be connected to a 230VAC/50 Hz alternating current
earthed wall socket, in compliance with NEN 1010 and local regulations. If necessary, place the wall
socket on the right-hand side of the fire, where a special opening has been made for a gas pipe and a
connecting lead and plug. Never shorten the connection lead, since this would complicate the removal
of the burner unit. Never position the fireplace against or in a combustible wall.
* If the fireplace is being connected to a chimney which has previously been fired with wood, coal or
oil, the chimney must be thoroughly inspected and cleaned. A draught of approximately 0.5 mm water
column is sufficient, measured when the fire is at full power.
If the draught is in excess of 2 mm water column, it is advisable to reduce the draught. If the room is fitted
with a window fan, or if the fireplace is being installed in a chink-free dwelling, pressure equalization open-
ings must be made into the outside air. This must be done to prevent the chimney from not working as a re-
sult of any negative pressure.
When gas fires are being installed, we recommend that these are connected to a fully aluminium or stainless
steel outlet duct measuring 100 mm, in order to avoid problems with the thermal outlet safety and other fea-
tures. If the appliance is being connected to an existing duct which had previously been fired with wood, coal
or oil, we also recommend that the above-mentioned aluminium or stainless steel flue be fitted.
5.2 Preparations for installing the fireplace
In order to build-in the fireplace, it must first be dismantled as described below.
1. Remove the front from the fireplace once it has been taken out of the box. To do this, loosen the
fastening screws: 2 inside the front at the top and 2 inside the front at the bottom, behind the service
door.

Page.6
2. Loosen 2 screws on the left-hand side to open the glass window. Open the glass window all the way to
the right and then lift the window upwards out of the hinges (see page 9 figure 1).
3. Remove decorative log set and burner.
4. Dismantle burner unit. First detach the two cable connectors of the outlet safety (T.T.B.) on the left-
hand side of the burner unit and draw the wire out. Disconnect the gas pipe.
5. Dismantling combustion chamber. Remove the 2 screws at the top left and right of the combustion
chamber (see page 9 fig. 2). The combustion chamber can now be pulled (forward) out of the built-in
casing.
5.3 Installing the fireplace.
1. Installing the built-in casing
Mount the pipe mouth of the fire to the outlet duct. In order to achieve maximum heat emission, we recom-
mend insulating the built-in casing with non-combustible insulating material. Now slide the built-in casing
under the outlet duct and mount the pipe mouth to the casing, using the four self-tapping screws supplied. Do
this by tightening the screws upwards from the inside of the built-in casing. The built-in casing has an up-
right finishing edge which is placed against the opening of the mantelpiece during installation, thus deter-
mining the correct recessed depth. If you screw the front onto the built-in casing, you will be able to establish
whether the casing is flush with the wall. The height of the built-in casing can be adjusted by means of 4 ad-
justment bolts in the bottom of the casing. When the correct height has been set, you must fix the built-in
casing to the floor. Do this by means of screws and plugs in the holes made in the base plate. (Screws and
plugs are not supplied)
Warning
The fireplace should not be completely built-in. The front must remain free, in connection with expansion. If
a new mantelpiece is being built, the built-in casing must not bear the weight of the mantelpiece. A mantle
iron should always be used, therefore, which must not rest on the built-in casing and bears the complete
weight of the mantelpiece.
2. Assembly combustion chamber
Slide the combustion chamber into the built-in casing and secure it again by means of the 2 screws.
3. Connection burnerunit
When mounting the burner unit, bring the lead of the fan out through the opening in the right-hand side of
the body. Slide the burner unit inside, well to the back of the combustion chamber.
4. Connection gas pipe
The gas pipe can be connected on either the right or the left-hand side. Fittings (3/8” G male thread) have al-
ready been mounted so that the burner unit can easily be dismantled later, for cleaning etc. The connection of
the gas pipe must be stress-free.
Important
Do not forget to reconnect the outlet safety (T.T.B.). Draw the lead for the safety device into the burner tray
and attach it to the two connectors of the thermocouple. If the connectors are not properly mounted, the fire
will not burn. In order to ensure that the fire functions well, the thermostat sensor should be placed outside
the fireplace, so that it reacts to the room temperature and not to the temperature of the fire. It must definitely
not be left inside the appliance.
Check
Use soapy water or a leak detector to check the gas tightness of the gas connection made. Put the plug for the
fan into the socket. Ignite the fire according to the operating instructions.

5. Positioning of ornamental log set (see page 11)
Position the ornamental log set exactly as shown in the illustration. Place the holes in the back logs of the set
over the pins in the bearing edge (back of combustion chamber) and subsequently lay the 2 rectangular logs
on the burner. Now position the remaining logs as shown in the illustration.
6. Fitting of glass window
Hang the glass window in the hinges. Close it and attach again with the two screws.
7. Fitting of the front to the combustion chamber/built-in casing
Place the front in front of the fireplace and attach it with the 4 screws: 2 at the top and 2 at the bottom behind
the service door.
6. DISMANTLING OF BURNER UNIT HV/LV AND FAN (HV only)
The burner unit and fan of a built-in appliance can be dismantled (the fan in the HV model only) without
having to take out the whole appliance.
This is done as follows:
1. Pull the fan plug out of the socket! (only in HV model)
2. Remove the screws with which the front is mounted (2 at the top and 2 at the bottom behind the service
door).
3. Loosen the screws with which the glass window is fixed and open the window.
4. Take the ornamental log set and the burner out of the fireplace.
5. Disconnect the two cable connectors for the outlet safety (on the left in the burner unit) and draw the
wire outside.
6. Close the main stopcock in the supply pipe and disconnect the burner unit from the pipe.
7. Pull the burner unit forward (be careful with the thermostat sensor).
8. Repair of the T.T.B. can be carried out in this phase, if required.
Dismantling fan system (HV model only).
In order to take out the fan, you must remove 3 screws at the back of the burner unit. The fan thermostat is
fixed with 2 screws to the partition at the right back of the burner.
Assembly is done in reverse order.
7. DISMANTLING OF T.T.B. BRACKET (see page 9 fig. 3)
Remove the two nuts and then take the T.T.B. bracket (3) out of the appliance with a turning motion, as
shown in figure 3.

Important tips for heating with gas-fired or wood-fired stoves and fireplaces.
Prevent discolouration of walls and ceilings!
There are always dust particles in the air in every living space, even if it is regularly vacuumed! These particles are clearly visi-
ble in rays of sunlight and they will not bother you as long as the concentration of particles in the air remains low. The indoor cli-
mate can only be described as bad if these particles are floating through the room in larger quantities for any reason whatsoever
and, above all, if the air is additionally polluted by soot and tar particles caused by the burning of candles or oil lamps for example,
and by smoking cigarettes or cigars! In a heated living space, cooled air slowly streams across the floor to the combustion appli-
ance. This air is heated in the convection system of the stove or fire, causing a fast-rising column of warm air to develop, which
then spreads throughout the room again. As a consequence, this air always contains dust and other pollutant particles that will
leave deposits on cold and often damp surfaces. This is potentially a particular problem in new buildings that are not yet dry
(construction moisture). An unwelcome result of this phenomenon could be discolouration of walls and/or ceilings!
How can you prevent these problems?
If the gas-fired or wood-fired appliance is fitted with insulated covering, one of the following materials should only be used:
§ Loose white insulation wool (heat resistant to 1000°C)
§ Rocktherm 180.012 insulation wool (700°C) from Rockwool, or the equivalent
§ Other mineral insulation wool without binding agents (synthetic resins) or water-repellent substances (mineral oils).
Wait at least 6 weeks before firing a newly-bricked chimney or after renovations, since the construction moisture must have disap-
peared completely from walls, floor and ceiling. The room where the appliance is located must be well-ventilated and the required
ventilation must be in compliance with the stipulations of the local Buildings Decree. Use candles and oil lamps as little as possi-
ble and keep the wicks as short as possible. These two “atmospherics” provide considerable quantities of pollutant and unhealthy
soot particles in your home. Smoke from cigarettes and cigars contains tarry substances which will also leave deposits on colder
and damp walls when heated. If the interior climate is bad, this phenomenon may also occur above radiators and lighting fixtures
and at ventilation grilles, although to a lesser degree.
