  • Check if gas supply is on

  • If the fire is hot wait for the fire to cool down.

  • If your fire has a remote handset, put the handset to one side and get access to the gas valve in the fire (see your user instruction on how to do this, if allowed).

  • Unless your fire is powered by a plug-in power supply, it will have batteries inside the valve to enable it to operate and these may need changing.

  • Gain access to the batteries by removing the battery cover. Check batteries are ok and there is no sign of the batteries leaking or any other contamination of the contacts. If in any doubt replace the batteries with newly purchased good quality batteries. (i.e. Energizer brand showed good results in our test).

  • When replacing the batteries ensure the battery contacts are clean and free from any contamination that may have come from the old batteries. Polish the contacts of both the valve and batteries to remove any finger print grease etc., being careful not to bend any contacts.

  • Ensure you replace the batteries in the correct orientation

  • Next replace the battery cover on the valve. (This is very important to do before doing the next stage.)

  • Check that the ceramic parts (matrix, coals or logs) on the fire are in the correct place and are in a good condition (according to the fire instructions).

  • Perform any general cleaning of the fire that is recommended in your user instructions, in particular the pilot assembly.

  • Replace any other part of the fire that needed to be removed to access the valve.
  • If the red light on the valve is on, reset the valve by pressing the on/off button briefly (the red light will go off).

  • Try to start the fire using the control button(s) on the valve.

  • If your fire still does not light normally, wait until the red light on the valve indicates an error or a lockout. Note: the valve may make several automatic attempts to start the fire, which could take several minutes to complete. Do not interrupt the valve while it does this).
  • Double check the above steps, particularly if the batteries are good and are in the correct way and everything is clean. If your fire user instructions cover cleaning the pilot follow these instructions. Reset the valve by pressing the on/off button as described above. Then try a starting again.



    Repeat starting attempts several times. If fire still does not work you may need help from a service engineer to service the problem. The appliance may need a good clean as debris may be stopping the fire from working properly. Check your user instructions on this and seek a service engineer if necessary to do this work for you as advised there.


    If the fire does work correctly when using the valve operation buttons, pick up the handset to check that is working as well. When holding the handset firmly (like a handshake), the green unlock keypad light should be permanently lit(not flashing).



    If it is not lit at all :-

  • Check the batteries in the handset are good, there is no contamination of the battery contacts, the contacts are not bent (preventing the battery contacts from touching them) and are in the correct way around
  • Note: If the battery contacts are contaminated, (i.e. from old batteries leaking), this may damage the handset and a new one may need to be purchased.
  • Clean and replace with new batteries as necessary.

  • IMPORTANT NOTE: The pairing of the handset is already done for you during manufacturing and is not forgotten if the batteries are removed.( If using a handset with display, the time will be lost after some minutes of no power but the pairing will remain. Refer to the instructions on how to set the time to restore the time to the display. Do not press the buttons on the valve to make a new pairing. If you do then you will have to reset the handset to accept an new pairing and make a new pairing, see the sections on restoring handset communication).



    If the green indicator is flashing like a heart beat, it is not in communication with the valve for some reason.



    Communication can be lost by:


  • The slide switch on the valve not in the on (I) position (see front page)
  • The batteries need replacing in the valve (see section above)
  • The handset is too far away from the fire( it needs to be some within a few metres )
  • If the above are correct, and the handset is still flashing, then the pairing on the valve may have been accidentally altered and the handset will need to be reset and a new pairing performed to restore communication
  • If the handset for what ever reason has lost communication with the Fire Control valve, when the handset is held like a firm handshake the green light will be permanently lit but will pulse brighter.

    In addition the communication symbol Restoring communication with a display type handset and other symbols will be missing from the display and it will appear as shown.

    Restoring communication with a display type handset



    To reconnect do the following :-


    Reset the handset to clear the old pairing and enable it to accept a new pairing:-


    Press and hold the set button and keep held for around 3 seconds until you hear a second beep. Release the set button and PROG appears at the top left of the handset. SETUP should also be flashing at the top right corner of the display.


    When SETUP is flashing, press and release the SET button to enter the menu. H24 (or 12) , will be flashing. Press and release the SET button about 9 more times until the display shows CA with a flashing 0. Press and release the + or – button once to change the CA0 to a CA1. Then press and release the SET button once again. The display will now show 7ESC r4 (or some other number next to the r).

    Restoring communication with a display type handset

    Ensure the handset and the gas fire control have good batteries inside etc as described in section

    If the handset is in its factory reset condition, the display will 7ESC and r and a number(as shown in the photo).


    Picking up and holding the handset will unlock the keypad and the green light will illuminate a solid green (and the LCD backlight may come on if the room is dark enough). (NOTE: Ensure the small isolation slide switch on the top left of the gas fire control is slid to the right, (I) position to turn the power on to the valve).

    Pairing the handset (with LCD display)


    Pairing the handset (with LCD display)

    Place the handset near the fire, i.e.within a metre (3 feet).No need to hold the handset at this time.


  • Simultaneously press and hold the - and + buttons on the gas valve control (not the handset) until the red light on top left of fire control begins to flash rapidly,(it will take about 5 seconds to start flashing), then immediately release the - and + buttons and quickly pressing just the power button on the gas fire control valve. Note: Pressing of the power button must be done within 1 second of the red light coming on. If not done quickly enough, then the above must be repeated until done correctly.

  • When done correctly you will hear an audible sound from the handset and the display will show the symbol " ⎤- -⎡ " and the green light on the handset will be flashing. You now have 60 seconds to accept the pairing. To do this pick up and hold the handset and hold it like a handshake to activate the unlocking of the keypad and press and hold the "SET" button for a few seconds.

  • <
  • You will hear a few beeps from the handset and the display will change and enter the setup menu. Whilst maintaining your grip on the handset, you can now set the display functions of the handset. Momentarily pressing and releasing the SET button advances through the settable features and pressing and releasing the MENU button returns to the previous one. Pressing + or – changes the displayed information, for example :-

  • H 24 – This is the 12 hr or 24 hours time format. Pressing and releasing + or – will change H24 into H12. Once happy with that setting, press and release SET to move to the day of the week.

  • Day of the week is Mo, Tu, We,Th,Fr, Sa, Su. Again pressing and releasing +/- will change the day and when happy press and release SET to move to the hour of the day.(Pressing Mode button at this stage will return the menu to the previous one , in this case H 24/12).

  • Do the same for the minute of the day and temperature display C or F.
  • The remaining parameters do not need adjusting so keep pressing and releasing the SET button several times( about 7 times) to advance the display to the end of the menu.

  • You know when the setup menu has ended as will see the communication symbol (3 arcs of a circle) in the upper right hand side of the display. This symbol indicates that the handset is in operation mode (not setup ) and in good communication with the fire valve control

  • IMPORTANT NOTE : Even in case you do not complete all of the setup, the pairing is still stored once accepted by pressing set the first time. The handset will re enter setup mode at next unlock (pick up) or by entering set up mode manually. Do not send pairing request again from the valve ! If this is done the another factory reset of the handset will be required and reset and new pairing done again.

    If the valve operates by the manual buttons on the valve okay but when holding the handset the green light on the handset pulses around once per second when held for a few seconds(or not at all on older handsets), then either :-


  • The gas fire control is out of range of the handset
  • the batteries in the gas fire control are flat or have bad connections etc.
  • the slide switch on the gas fire is in the off position
  • the handset pairing has been broken and needs resetting and pairing again.

  • Note: Taking batteries out or replacing dead batteries does not affect the pairing . The handset remains paired even without batteries inside. To re-establish communication of the handset if lost for any reason, the handset will have to be reset to clear the old pairing information to enable it to accept a new pairing from the gas control. The most common reason for lost pairing is mistakenly pressing the +/- buttons of the valve together and so changing the communication channel.


    Resetting a handset to accept new pairing:-

  • With good batteries inside, hold the handset to unlock the key pad, and press and hold the set button for around 10-15 seconds and keep held until the red and green lights are flashing. They will flash for up to 10 seconds.
  • Quickly while the red and green are flashing, open up the battery compartment on the handset and remove one of the batteries for about 30 seconds.
  • Replace the battery and the battery cover.
  • Now when you hold the handset the green light should be flashing faster(several times a second), the handset is now able to be paired with the valve, see the next section. (Note: If the red and green lights do not flash together, then the handset is probably already reset and ready to pair again.)
  • Restoring communication with a standard handset (without LCD display).



    Once reset go to next section on pairing the handset.

    Ensure the handset and the gas fire control have good batteries


    If the handset is in its factory reset condition( as performed in previous section) when held the green light on the handset will be flashing quickly.


    (NOTE: Ensure the small isolation slide switch on the top left of the gas fire control is slid to the right, (I) position to turn the power on to the valve).

  • Place the handset near the fire, i.e. within a metre (3 feet). No need to hold the handset at this time.

  • Simultaneously press and hold the - and + buttons on the gas valve control (not the handset) until the red light on top left of fire control begins to flash rapidly,(it will take about 5 seconds to start flashing), then immediately release the - and + buttons and quickly pressing just the power button on the gas fire control valve. Note: Pressing of the power button must be done within 1 second of the red light coming on. If not done quickly enough, then the above must be repeated until done correctly.

  • When done correctly you will hear an audible sound from the handset and the green light on the handset will be flashing more slowly than before. You now have 60 seconds to accept the pairing(if not accepted within 60 seconds the green light stops flashing. Simply repeat the above to send a new pairing. * To accept the pairing sent from the valve hold the handset it like a handshake to activate the unlocking of the keypad and press and hold the "SET" button for a few seconds.

  • You will hear a few beeps from the handset and the green light will now be permanently lit when held. When ever the green light is on and not flashing this means the handset is is good communication with the valve. If flashing see earlier sections for the possible reason(s).

  • Note: There is a certain way to press the power button to enable the fire to start that may not be obvious. This is done for safety reasons. Read the next section on operating the handset to show how to press the start button correctly.

    Error codes are to assist in diagnosis of why the fire cannot start. They appear if the control detects abnormal conditions with the fire ,either in environment, in installation or components or internal the electronics.( If you do not have a handset with a display that shows the error codes, then checking for the faults below are still valid. The illumination of the red indicator light show the valve is in error).


    Note : To reset any error code, press and the power button Error codes on the valve. False error can be reported if the batteries are faulty or lack enough power to operate the valve.

    This is the only code where the red indicator stays permanently lit without flashing(on newer models the indictor will dim after a few minutes to save battery power). E00 occurs after attempting (but failing) to light after all automatic start cycle(s). If this happens it is a sign that the electromagnet within the valve has not received enough power from the thermocouple at the end of the start cycle(s). The main burner may light for 15 to 30 seconds on each start cycle but then go off.


    Possible reasons:

    Thermocouple - Not being heated or heated quickly enough;


  • No gas at all to pilot /main burner;
  • Check gas supply is on and supply pipes for contamination that may be blocking gas flow to the valve inlet.
  • Pilot pipe from valve to pilot blocked
  • Pilot injector blocked.
  • Pilot head damaged or contaminated(See fig xx)stopping good flame heating thermocouple.
  • Debris from fire ceramics out of position or causing carbon deposits to contaminate pilot.
  • Small pilot hole blocked by lint
  • No Spark at electrode, tracking out somewhere (i.e. damaged isolation, spark gap too wide, damaged electrode – crack in ceramics, dirt or soot on electrode(causing tracking out) or ceramic body of electrode.)
  • Flame is not touching the spark electrode.(The electrode needs to be in the flame as the valve is sensing the flame through the electrode and cable in addition to the thermocouple).
  • Flame signal shorted out. This can occur if any liquids (i,e, leak detection spray) has been used and contaminated the area of the pilot terminals connection or inner workings of the valve.
  • Spark cable is open circuit (spark may be present as it can jump gaps but if there is a break in the cable or if inner metal terminal under ignition cable plastic terminal cover on valve is not in good contact with the high voltage outlet connection terminal on the valve, then valve will not continue after ignition cycle as no sensing current is reaching the valve. Another sign of this fault is the control may light the pilot but not the main burner and will not stop sparking, as it has not detected a flame.
  • Thermocouple is aged or damaged and is not producing enough output
  • The insulation on the thermocouple wire is damaged ( i.e on a sharp edge) and the electrical current is shorted to chassis metal).

  • Note: If stop is pressed during a start cycle, E00 may also be generated. This is normal and not a failure condition. The valve can attempt self fix issues. When an E00 code has been displayed this will initiate a recalibration of the internal valve mechanics to compensate possible deviations due to contamination, ageing and so on. If the fire does not light on the first cycle, allow the valve to complete

    This error is intended to indicate that possibly the content of CO is too high in ambient atmosphere. This error will usually be generated when there ha been a good electronic flame signal, but the temperature of the couple was once hot enough but then become cooler.


    Possible reasons;

  • Problems with chimney or room air inlets (insufficient air circulation)
  • Unstable pilot flame (i.e. wind, insufficient thermocouple couple position)
  • Contaminated pilot, giving poor flame that heat thermocouple)
  • Poor position of Ceramic parts (i.e. coals logs or matrix)
  • Intermittent failure in Thermocouple (only when hot) Inner wire in head maybe making contact when cold but not when hot.
  • Ambient around Gas valve in the fire too hot (exceeded 72°C). Note: This error protects the fireplace and the valve from excessive temperatures.


    Possible reasons:

  • Faulty installation of fire ( not sealed in correctly in fire opening).
  • Problems with chimney (insufficient air circulation)
  • Poor position of Ceramic parts (i.e. coals logs or matrix)
  • Note: Batteries do not tolerate well high ambient temperatures, eventually this could cause them to leak and damaging the valve and new valve will be required and is not covered by any warranty. Typically the maximum temperature for alkaline batteries is 50 C.

    Thermocouple connection to valve issue. Incorrect reading from thermocouple.


    Possible reasons:

  • No Thermocouple connected
  • Thermocouple connection reversed / connected incorrectly (see fig xx for correct connection)
  • Insulated thermocouple wire shorting to chassis earth
  • Flame detected on pilot after valve has shutdown.


    Possible Reasons:

  • Carbon or soapy / conductive contamination on spark electrode.
  • Combustible material burning on pilot near electrode (Carbon deposits etc),
  • If Easy test box used :- simulate flame switch not operated correctly
  • Flame detected on pilot before valve has started .

    Possible Reasons:

  • Carbon or soapy / conductive contamination on spark electrode.
  • Combustible material burning on pilot near electrode (Carbon deposits etc),
  • If Easy test box used :- simulate flame switch not operated correctly
  • Occurs when supply voltage is too low to operate the valve.
    Possible reasons:

  • Batteries are completely flat( may display random error codes in this case not just E06 and 7).
  • Damaged battery contacts (dirty, corroded, bent so not making strong contact with batteries)
  • Short circuit in external wiring or connected accessories (i.e. wired control panel, cable shorting to chassis earth.)
  • Defective power plug power supply (if used) or damaged wiring to it.
  • Contact problem of slide switch (moving on/off..on/off several time may clean contacts)
  • Batteries not in correct way around
  • Rises when a device connected to the TESC extension socked do not work correctly.


    Possible reasons:

  • If nothing connected: are links are missing, in wrong position or bad contact
  • Failure in extension module connected to extension connector
  • Not applicable - only should occur during valve manufacturing and reserved for future use.

    Occurs when buttons on valve (or wired control panel) do not work or are not wired correctly


    Possible reason:

  • Buttons are sticking or blocked
  • Buttons are damaged
  • Cable damaged or short circuit to ground (wired control panel)

  • Note: disconnect wired panel (if applicable) and test again to determine the root cause

    Occurs when internal CPU diagnostics runs self tests and returns invalid results


    Possible reason:

  • EMC problems (in this case, twist ignition cable around thermocouple wire several times to quench radiated EMC emissions)
  • Spark track out somewhere but not at electrode creating unusual interference
  • Reserved for later use.

    Occurs when thermocouple does not reach its final temperature within 1 minute


    Possible reasons:

  • Aged thermocouple
  • Thermocouple wire insulation damage and shorting to metal chassis.
  • Problems with chimney or room air inlets (insufficient air circulation)
  • Unstable pilot flame (i.e. wind, insufficient thermocouple couple position)
  • Contaminated pilot, giving poor flame that heat thermocouple(see section on pilot)
  • Poor position of Ceramic parts (i.e. coals logs or matrix
  • Occurs when a power supply with wrong pinning is connected to the USB-socket

    Occurs when a self test procedure of the valve electronic fails.


    Possible reasons:

  • Completely flat batteries
  • Liquids inside electronic (i.a. after leakage test with soapy water)
  • Occurs when internal piston is having trouble moving.


    Possible reasons:

  • Contamination of valve in- outlets with debris from supply pipe or other.
  • Mechanical damage of the valve

  • ote: After cleaning etc, before resetting these error codes allow the fire to cool down. Upon starting the valve will reinitialise and perform a self recalibration and needs to be cold when doing this recalibration. Note: If the valve needs replacing, check the pipework for contamination to avoid repeated problems.

    Occurs when the control detects a short circuit of the couple


    Possible reasons:

  • Thermocouple connection reversed / connected incorrectly
  • Insulated thermocouple wire shorting to chassis earth (damaged insulation).
  • Damaged or defective , worn out thermocouple
  • Weak connection of thermocouple to valve
  • Occurs when the control senses a false flame signal on electrode


    Possible Reasons:

  • Contamination of the electrode with carbon deposits, conductive liquids(leak detection spray) or similar.
  • Contamination of the rear of the valve where the thermocouple and ignition cable connect to the valve with conductive liquids(leak detection spray) or similar.

  • Note: It is critical to avoid leak detection fluid to contact any part of the valve other than the threads where the pipe connects. Leak detection fluids are highly corrosive and will damage any electronics they come into contact with. Other forms of leak detection should be used.
