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 .

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.

Extend the supplied thermocouple with just the original extension. (available from your supplier)

Unauthorized extension of the thermocouple has the effect of stress reduction, thereby the magnetic coil can not be activated.

Prevent leakage of the ignition spark to other parts of the installation than the Ignition by the pilot

Keep the ignition free of hull or other metal parts. If cable extension is used, see to it that connections are additionally insulated with silicone grommet.

For automatic start via the transmitter, the receiver and the control the gas control valve to be switched

The oval disk on the gas control block should be turned to the ON position. The I/0 switch should to be set to "I". The ignition must be connected to the receiver box at the terminal SPARK.

The transmitter's contains the thermostat sensor system

The transmitter operates best at 2 to 3 m from the unit. Although the communication via short wave radio signals takes place, it is recommended that the transmitter in the 'visibility' of to lay the gas apparatus in a place where the user wants to experience a pleasant temperature. Place the hand transmitter in direct sunlight or other hot places. The thermostat measures the temperature and regulates the flame size of the gas in accordance.

Remove batteries only with the red ribbon which is under the battery, not with metal tool

Removing batteries with a metal object, the electronic control can permanently damage.

5. INSTRUCTIONS FOR MERTIK MAXITROL GV60 GASCONTROL

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.

WARNING

IN THE EVENT OF REPLACEMENT

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.

NOTICE

WARNING

It is forbidden to start up the unit if window (s) are not present or broken!

The concentric flue system is composed of an inner- and an outer tube. These tubes are concentrically arranged; through the inner tube, the combustion gases are evacuated and the fresh combustion air is supplied between the inner and outer tube.

9.1 Components of the concentric flue system.

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 lay outs for this system,

however, there are a few important requirements/conditions:

* The maximum recommended 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. * Ducts may not be insulated.

8.2 Construction of concentric flue system

Indirect wall connection.

* The outlet may be installed 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 locking bands. * An adjustable length can be used between the bends or when connecting to the unit.

If necessary, use wall brackets to support the flue.

Rooftermination.

* 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 roof flashing for a flat roof or a lead flashing for sloping tiled roofs can be used for a watertight connection. Use various elbows for making the proper connection, 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 flue must be installed dripless. Connect the elements by using locking bands. Ensure the gas tightness of all connections is correct. * An adjustable length can be used between the elbows or when making the connection to the unit and/or the roof terminal. Use 2 wall brackets to support the flue on each floor.

8. CONCENTRIC FLUE SYSTEM

NOTICE

Ensure the restriction plate in the fire 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.

SYMPTOM ACTION TO BE TAKEN

The pilot flame will not light after repeated ignition.

1. There is air in the pipes if you switch the unit on for the first time or after a service. It will take a little while until all the air has flowed out of the pipes and gas flows through that can be ignited. Take it away and try to switch the pilot flame on several times in order to allow the air to escape.

2. See whether the gas pipe to the unit is open and if there is sufficient gas pressure to the unit.

3. Check whether there are sparks between the spark electrode and the pilot. If there are no sparks:

a) Check whether the connection between the electrode and the ignition is broken or

faulty. b) Check whether the spark short circuits at another point or jumps. c) Check whether the electrode is broken.

The pilot flame will not remain alight after ignition.

1. Check whether the pilot flame is large enough to burn around the thermocouple. If the flame is too small, you need to check the gas feed pressure. If the size of the pilot flame cannot be adjusted, there may be an obstruction in the pilot.

2. Check whether the thermocouple interrupter is connected to the gas valve properly.

3. Check that the gas valve is not faulty.

4. Check whether the restriction plate has been placed according to instructions

The main burner goes out when the unit is warm.

1. This can be a normal effect of the thermostat. Check whether the pilot flame is able to heat the thermocouple adequately. If the pilot flame is too small then the gas pipe or the pilot flame adjustment need to be checked.

2. Check whether the restriction plate has been placed according to instructions (see page

25).

Soot deposits on the glass. 1. Check whether the lava split is lying on the burner in the correct manner.

2. Check if the pilot burner is free from burner filling.

3. Check whether there is any blockage in the burner openings.

4. Check if the flue tube is functioning correctly and if the flue tube is not hindered or

blocked.

5. Check the pipe pressure.

Sharp blue flames that are released by the burner or a pilot that burns too wildly.

1. Check whether the restriction plate has been used.

Weak (stifling) pilot flame. 1. Check the pilot burner pressure or duct pathway.

Main burner will not burn after the pilot burner is functioning.

1. Check if the motor button turns and whether the batteries are empty.

2. Possible defect in the gas block.

3. Check whether the pilot flame ignites the burner well.

4. Check that the burner opening is not blocked.

10. PROBLEMS AND POSSIBLE SOLUTIONS

WARNING

Solving problems with your unit, whether gas related or electrical, must always be performed by a qualified technician.

NOTICE

Please first check if all guidelines were followed before attempting to solve any problems with the unit.

APPENDIX 2 INSTALLATION EXAMPLES

The stove must be located at least 280mm from any combustible materials. A combustible shelf may be fitted over the appliance, if in the case of a 150mm or less deep shelf, there is at least 280mm clearance above the top of the stove. The shelf depth may increase at the same rate as the increase in clearance; i.e. a shelf depth of 200mm would require a clearance of 330mm.
