b.
For Both Control systems, Battery replacement is recommended at the beginning of each heating season, or when an acoustic
error message sounds during ignition.
c.
Error Message – Long signals (0.8 second tone – 0.2 second break) during ignition – probable cause - batteries in electronic
receiver box are nearly discharged.
d.
Error Message – 5 second continuous tone – probable cause – cable disconnected or on/off switch on valve is in off position.
e.
Batteries - Electronic Receiver Box - 4 x AA good quality alkaline - Handset - 1 x PP3 good quality alkaline.

battery compartment. You can detach the Receiver by pulling it off its Velcro Pad to make access easier but remember to put it
back in the same position.
Note: Only Change The Batteries When The Fire Is Cold
! WARNING! THE THERMOSTATIC THERMOTRONIC CONTROL SYSTEM PROVIDES THE
MEANS FOR UNATTENDED OPERATION OF THE FIRE IF THE PROGRAMS OR THERMOSTATE
SETTINGS ARE USED - THIS COULD POSE A DANGER IF COMBUSTIBLE MATERIALS ARE TOO
CLOSE TO THE FIRE OR IF YOUNG CHILDREN, THE ELDERLY OR INFIRM OR PETS ARE LEFT IN
ATTENDANCE.
3.5 - RESETTING THE MERTIK MAXITROL LOGIC CIRCUITS - IF THE HANDSET DOES NOT WORK
APPLIES TO BOTH CONTROL SYSTEMS
Must only be done when the fire is Cool
Basic Reset -
It sometimes happens that (such as when the handset buttons are pressed out of sequence) the fire stops
working because the logic circuits get confused and need to be reset.
To do this, simply remove the 4 x AA batteries from the Receiver Box (see section 2.4f above), wait for 1 minute and then refit the
batteries. Wait for another minute and then point the handset at the fire and press the red/off button. Wait for another minute and
then start the fire as normal. If the fire does not start repeat the resetting procedure. If the fire still does not work a Full Reset can be
tried.
Full Reset
- If you obtain a new handset the control system will need to learn the handset’s unique code via a Full Reset. Also, if the
fire is not working and the Basic Reset has not worked a Full Reset can be carried out:
Open the outer door by pulling at the left side to release it from the magnetic catches and open the outer door, locate the electronic
Receiver Box.
Locate the Reset Hole on the side of the Receiver and using a pen press and hold in the Reset button until you hear two beeps.
The first beep is short and the second beep is long. After the second beep release the Reset Button.
Now on the Handset, within the next 20 seconds press and hold the Small Flame Button until you hear two additional short beeps
confirming the code is set in the Receiver.
If you hear one long beep the Code as not been set so repeat the procedure.
If after carrying out the above procedure the situation is not corrected it will be necessary to contact your Installer.
Note: For the Installation/Service Engineer
- Resetting of the Handset & Control System is also covered in Section 21.1 page 29.
