We hope you really enjoy the warmth of your new gas fire. Read these instructions carefully before in-
stalling and using the gas fire. Keep these instructions in a safe place. Always provide the following infor-
mation if the gas fire breaks down: model and serial number, which can be found on the unit. Your pur-
chase invoice is your proof of warranty.
1. General
The entire unit is delivered to you with your choice of mantle and/or accessories. See the installation instructions
for the relevant mantle and/or accessories that are packaged separately from the unit. Check the unit immediately
after delivery to confirm that it has not been damaged during transport. If it is damaged in any way, please in-
form your supplier immediately and provide as many details as possible.
Attention
The unit must be installed, connected and checked by a qualified fitter based on national, regional, and local
standards and regulations. The fitter must inspect the unit for tightness in relation to gas and combustion prod-
ucts and correct operation of the different components and functions.
The flue tube system and the outlets in the outer wall or roof face must also meet the requirements of the applica-
ble regulations.
The unit falls in the closed unit category, in a set-up location without a fan and with a chimney loss that is
greater than 17% (non-condensing).

2. SAFETY DEVICE
The unit is fully safeguarded by means of thermo-electric pilot light protection to prevent unforeseen discharge
of gas from the main burner.
2.1 Safety
Do not place ceramic burner decoration material or logs against the pilot burner. Ensure the pilot light is able to
burn freely over the main burner. Good ignition of the main burner is only guaranteed if this is the case. Not ad-
hering to these instructions can lead to dangerous situations.
The unit, complete concentric flue system and flue terminal need to be cleaned and checked annually by a
recognised gas technician/fitter, so the unit continues to operate safely. For additional instructions, see
Chapter 10: Maintenance.
If, for whatever reason, the pilot light extinguishes, you must wait 5 minutes before igniting the pilot light
again.
The unit may not be operated without the glass panel being in place.
It is not permitted to place flammable materials on the ceramic wood inset.
The layout of the main burner with ceramic burner decoration material and wood inset may under no cir-
cumstances be changed or added to.
Light flammable materials, such as nylon clothing or flammable liquids, may not be placed near the unit.
Ensure children and other persons unaware of the operation of a gas unit, are supervised at all times when
near the unit.
Use a fireguard to protect against burns and protection of the children and persons named above.

5. INITIAL START-UP
The unit has a layer of heat-resistant varnish that resists very high temperatures. An unpleasant smell may de-
velop in the first hours after starting the unit due to burning in of the varnish; however, this is not dangerous. To
accelerate this process, allow the unit to burn at the highest setting for several hours and ventilate the area well.
After the first time the unit is turned on, a light deposit may form on the inside of the window. This is due to the
varnish hardening. After the fireplace has cooled down, this deposit can be removed using a fireplace glass
cleaner or ceramic hotplate cleaner.
5.1 Daily maintenance
* Avoid having a lot of dust and cigarette smoke, candle and oil lamp particles in the air of your home.
Heat ing of these particles through the convection system of the unit, can lead to discolouring of walls and
ceilings. It is therefore advisable to ensure the area containing the unit is always sufficiently ventilated.
Regularly remove any dust that has settled behind the operating lid with a vacuum cleaner.
If the glass is broken or cracked, it should be replaced immediately by a recognised fitter before the
unit is used again.
* The unit must be switched off immediately if something is spilt on it. It should only be cleaned once the
unit has cooled down. Never use abrasive, aggressive cleaning products or fireplace cleaner; only use a dry
cloth that does not give off fluff.
* Your local specialised dealer will be able to provide you with spray cans containing heat-resistant varnish,
so that small stains or damages may be touched-up during annual maintenance.
5.2 Important tips for gas heating or wood fuelled units and fireplaces.
Prevent discolouration of walls and ceilings!
There are always particles in the air in each living area even if the area is vacuum cleaned regularly!
These particles are easily visible when the sun streams in. This issue will not arise if the amount of particles in
the air is limited. If these particles are present in greater quantities and particularly if the air is contaminated by
soot and tar particles, for example, through the burning of candles or oil lamps and cigarette or cigar smoke, then
we can speak of a poor inner climate! Cooled air slowly flows over the floor to the heater in a heated living area.
This air is heated in the convection system of the fireplace or heater, resulting in a quickly rising column of air
that subsequently spreads through the room again. This means there is always dust and other polluting particles
depositing on cold and often damp surfaces. This issue occurs especially in a new building (building damp) that
is not yet dry. An undesirable consequence of this phenomenon could be discolouration of walls and or ceiling!
How can this problem be avoided?
* With a newly built fireplace or following renovation, wait at least 6 weeks before firing up.
* The building damp must have disappeared completely from the walls, floor and ceiling.
* The room where the unit is located must be well ventilated.
* The required air ventilation must be in line with local building regulations.
* Limit the use of candles and oil lamps and keep the taper as short as possible.
* These two creators of atmosphere ensure considerable quantities of polluting and unhealthy soot particles
in your house.
* Among other things, cigarettes and cigars contain tar that will precipitate on cold and damp walls during
heating.
* This may occur above radiators and light fittings and with ventilation grilles (if there is a poor internal
climate), although to a lesser degree.

6. INSTALLATION INSTRUCTIONS
Important
The installation may only be performed by an authorised person
6.1 General instructions
* The gas fireplace must be installed, connected and inspected as a closed unit by a qualified fitter, according
to national, regional, and local standards and regulations.
* The flue tube system and the outlets in the outer wall or roof face must also meet the requirements outlined
in the applicable standards and regulations.
* The temperature of the walls and shelves near the side and back of the unit may not be more than 80°C
higher than the temperature of the environment.
* The unit has been approved in combination with the Metaloterm US system number: 0063-CPD-6308 con-
centric flue system Ø100 mm - Ø150 mm and Ø130 mm - Ø200 mm , in accordance with European CE
standards for gas units, and may therefore only be applied with this system.
* The unit needs to be inspected by the fitter for local gas distribution (gas type and gas pressure) as indicated
on the identification plate.
* The instructions are only applicable if the relevant country code is stated on the unit. If this is not the case,
the gas technical information for the relevant country needs to be consulted and modifications discussed
with the manufacturer.
* There will be air in the gas pipes when the unit is first used. The gas pipes therefore need to be vented first.
* Ignite the heater according to operating instructions and check whether the burner flame is uniform. After
the unit has been used for the first time, you should remove any deposits resulting from convection-curing
of the unit, from the glass window using a glass cleaner for heaters.
Warning:
Never install the unit against or within a flammable wall!
Distance to flammable materials:
* With respect to the front, side and top of the unit, a distance of 1000 mm needs to be kept between the unit
and: curtains, floor covering, upholstery and fabrics, and/or other flammable material unless stated other
wise in these instructions.
Distance to non-flammable materials:
* The unit needs to be placed a minimum distance of 50 mm from the wall unless stated otherwise in these
instructions.
Important
* Construction material for fireplaces and mantles etc., or for an assembly must be made of non flammable
material. This also applies to floors and ceilings. Never use flammable materials near the unit in compli-
ance with the abovementioned instructions.
Note: Please contact your supplier if you are unsure.

7. CONCENTRIC FLUE SYSTEM CC
The concentric flue system consists of a 100mm or 130mm Ø inner flue concentric with a 150 mm or 200 mm Ø
outer flue. These flues have been set up concentrically; the combustion gases are exhausted through the internal
flue while the fresh combustion air is supplied between the internal and external flues.
7.1 Components of the concentric flue system. (See page 29,30 and 31)
Different connections are possible using the concentric flue system. These are:
Through the roof face and through the exterior wall.
There are various options for mounting the pathway for this system,
however, there are a few important requirements/conditions:
* The maximum allowable vertical flue length is 12 metres (the sum of the flue length and the calculation
lengths for the bends).
* 90° bends have a 2-metre horizontal calculation length.
* 45° bends have a 1-metre horizontal calculation length.
* The outlet can be installed at any point on the roof face or exterior wall (supply and discharge in an identical
pressure area), but must meet applicable regulations.
* Duct pathways may not be insulated
Important
* Ensure the restriction plate is mounted in the correct manner, as indicated in these instructions.
* The correct restriction plate will provide the unit with the most optimal efficiency, flame image and
combustion.
* Mounting an incorrectly placed restriction plate may cause malfunction of the unit.
7.2 Construction of concentric flue system CC
Indirect wall connection.
* The outlet may also be installed above the exhaust in the wall, taking any hindrance to the surrounding area
into consideration, according to national, regional, local standards and regulations. Ensure wind pressure on
the flue terminal is not too extreme, such as a balcony, flat roof, corners and in small alleys etc., as this may
negatively influence the unit efficiency.
* Provide a recess in the exterior wall of around 155 mm for concentric 100-150, and 205 mm for concentric
130-200. (in a flammable wall ensure there is 50 mm of extra space around the outer pipe and use
fireproof casing) and fix the exterior wall duct with the wall plate to the outer side of the wall. The wall
plate of the exterior wall duct must be sealed sufficiently against the wall on the outside, to avoid moisture
and/or flue gas leaks into the living space.
* The flue should be cased if necessary. Sufficient fireproof measures must also be taken when the flue is
being mounted along flammable materials.
* Determine the position of the unit and outlet and begin construction of the flue with the connection on the
unit, paying attention to the direction of installation and connecting the elements by means of clamp strips.
* The fitted pipe can be used between the bends or when connecting to the unit.
If necessary, use wall brackets to support the flue
Mounting using the roof pass-through option
* The flue terminal can be located at any random place on the roof face (supply and exhaust in identical
pressure areas) and must meet the applicable rules and regulations.
* A roofing sheet for a flat roof or a roofing sheet lead for sloping tiled roofs can be used for a watertight duct.
Use various bends for the slope, if required. The recess in the roof decking should be 5 cm larger all
around, to ensure sufficient fire resistance.
* One needs to take into account the regulation regarding fire resistance between rooms (See national,
regional, local standards and regulations). A casing made of fireproof material (e.g. 12 mm Promatect fire
resistant plate) must be used at 25mm from the outside duct.
* Determine the position of the unit and outlet and begin construction of the flue with the connection on the
unit (always 1 metre vertical first), paying attention to the direction of installation! The inner flue must be
installed for draining purposes. Connect the elements by using clamping strips. Ensure the gas tightness of
all connections is correct.
* A fitted pipe can be used between the bends or when making the connection to the unit and/or the roof pass-

8. Instructions for the Mertik Maxitrol GV60 and the Remote Control:
Ensure that the fuel supplied to the unit is clean and free from particles and moisture.
Before a gas supply pipe (new or existing) is connected to the main gas pipe at the gas meter and to the gas
control block of the unit, clean and dry compressed air should been blown through it.
Cut copper pipes as well as aluminium pilot pipes must be deburred and blown clean before they are
connected. The dust filter at the connection to the gas control block will only filter out the coarsest dirt
from the system. Fine particles are still able to reach the inside and may damage and/or adversely affect
regulation in the gas control block .
Heat, moisture and dust are a threat to all electronic components
Protect the electronic gas control until all construction, plastering and paintwork has been completed. If
such work cannot be avoided, then protect the control against dirt and moisture penetration by using, for
example, plastic film .
Warning
Electronic components will become permanently faulty when exposed to temperatures higher than 60°C.
Standard AA batteries will crack open at temperatures >54°C and the battery contents will damage the
electronic switches located underneath. Batteries last longest at <25°C. At >50°C the life span is around 23
weeks, this makes the use of the gas fire unnecessarily expensive.
Only install the gas control block and receiver as pre-installed at the factory
Remember that components may have to be replaced or that repairs may have to be performed at a later
date.
This may be more difficult if the control is installed using a method that is different from the instructions
provided here.
Please note!
Only place the batteries after wiring to the receiver, gas control block and pilot set is connected.
Premature connection to the energy source may damage the control’s CPU (central processor).
Ensure that the ignition cable is not near the antenna wire and that they do not cross each other.
The high voltage released at ignition may damage the sensitive receiver circuit.
This may mean that the unit becomes less responsive or not responsive at all to handset commands. (See
photograph 1 on page 16)
If the manual transmitter range is too limited, loosen the antenna wire from the terminals on the
receiver box. Direct the antenna wire away from the ignition cable and in the direction of the control
box door.
Ensure there is no contact with metal components. Ensure there is no damage to the connection to
electronic components or to the wire itself. (See photograph 1 on page 16)
Connect the wires correctly to the contact breaker behind the gas control block.
The shortest wire runs immediately back to the 1/0 switch and can be found nearest to the back of the gas
control block. The longest wire runs to one of the two connections on the receiver box and only fits on one
of the screws .
Do not tighten the contact breaker and the thermocouple connection too tightly on the gas control
block or to each other.
It is sufficient to tighten by hand and add a half a turn with an open-end spanner. Tightening too much
will break the connection to the magnetic coil below and/or the insulation around the aluminium contact
pin in the contact breaker. This may lead to the magnetic coil not opening the gas supply to the pilot and
the unit not working.

Page.16
Do not extend the thermocouple supplied to the pilot set
Extending the thermocouple beyond its limit will lead to a reduction in voltage. This may, in turn, lead to the
magnetic coil not being activated.
Prevent leakage of the ignition spark to parts of the installation other than the ignition rod at the pilot.
Ensure the ignition cable is not in contact with the shell or other metal parts. If a cable extension is used, ensure
that connections are additionally insulated using silicone.
The receiver and the control units on the gas control block should be switched on to ensure automatic start
-up through the manual transmitter.
The oval disk on the gas control block should be turned to the ON position. The I/0 switch should be set to 1. See
photograph 2. The ignition cable should be connected to the SPARK connection point on the receiver box. See
photograph 1.
The manual transmitter has to communicate with the receiver. This has to be ‘learnt’.
Press the RESET button using a blunt object. (See photograph 3.) Continue to press this button until you hear a
short beeping sound, followed immediately by a long beeping signal. Release the button. Direct the manual trans-
mitter towards the receiver and press the arrow down until you hear a long beeping sound. The gas control button
will now move for a short period.
The manual transmitter has now learned the setting with regard to the receiver and the unit can now be ignited
using the remote control.
The system’s thermostat sensor is in the manual transmitter.
The manual transmitter operates best at a distance of 2 or 3 metres from the unit. Although communication oc-
curs via short wave radio signals, it is recommended to place the hand transmitter in view of the gas apparatus in
a place where the user wishes to experience a pleasant temperature. Do not place the manual transmitter in direct
sunlight or other warm location. The thermostat measures the temperature and regulates the flame size of the gas
unit accordingly.
Only remove batteries using non-metallic tools.
Removing batteries with a metal object may damage the electronic control permanently.
