USE & MAINTAINENCE INSTRUCTIONS
(
continued)
USING THE RADIO FREQUENCY CONTROL SYSTEM
Control can only be achieved if the handset is pointed at the fire. The red light will flash each time
you press a
button on the handset.
a. Ignition
Simultaneously press and hold the red button and the right upper button (linked by line) until a short acoustic
signal confirms that the sequence has begun, then release the buttons. Continuous audible signals confirm
that ignition is in progress. When pilot ignition is confirmed the motor will open the valve to maximum flame
height – this takes about 30 seconds.
b. Flame Height Adjustment
Press the small flame button until the flame height is at the desired position. If you try to go beyond the
preset low flame minimum height the main burner will turn off leaving the pilot burner alight (this is the
standby position). You will learn from experience the preset low flame minimum height.
To relight the fire from the standby position, or to increase the flame height from low flame, press and hold
the large flame button until the desired flame height is achieved. Please note that you can have the flame
height anywhere between maximum and preset low. For fine adjustment simply tap the up or down arrows.
c. To Switch Off
Press the red/off button on the handset.
d. Manual Off Switch
If your handset is mislaid, or for some reason the batteries fail while the fire is running you can turn the fire
off with the on/off switch located at the front right hand corner of the fire. This switch interrupts the thermocouple current to the
control system and shuts down the fire immediately. This switch must be put back into the on position to relight the fire.
e. General
Battery replacement is recommended at the beginning of each heating season, or when an acoustic error message sounds during
ignition.
Error Message - Long signals (0.8 second tone - 0.2 second break) during ignition - probable cause - batteries in receiver are nearly
discharged.
Error Message - 5 second continuous tone - probable cause - cable disconnected or on/off switch on valve is in off position.
Batteries
Receiver Box - 4 x AA good quality alkaline
Handset - 1 x PP3 good quality alkaline
RESETTING THE MERTIK MAXITROL LOGIC CIRCUITS (RADIO FREQUENCY CONTROL)
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 (do not use metal tools
to do this), 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 (see below).
Note: If an extended battery box has been supplied, and the lead has been unclipped from the battery box, do not let the lead terminals
touch any metal parts, because voltage is still stored in the capacitors, which can cause a short circuit.
FULL RESET – TO BE USED IF A REPLACEMENT HANDSET IS OBTAINED
NOTE. On some burners such as the Fireboxx and “sunken” burners it is not possible for the user to access the Receiver Box
to carry out a Full Reset. If the user cannot access the reset button on the Receiver Box a Qualified Installation Engineer will
need to remove the burner to do so and this will involve disconnecting the burner from the gas supply.
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 (described above) has not worked a Full Reset can be carried out:
a.
Replace the batteries in the Receiver and Handset.
b.
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.
c.
Now on the Handset, within the next 20 seconds press the Small Flame Button until you hear two additional short beeps
confirming the code is set in the Receiver.
d.
If you hear one long beep the Code as not been set so repeat the procedure.
e.
If the fire still does not work, the problem lies elsewhere.
Note: If an extended battery box has been supplied, and the lead has been unclipped from the battery box, do not let the lead terminals
touch any metal parts, because voltage is still stored in the capacitors, which can cause a short circuit.
CLEANING THE FIRE
a.
Do not use a vacuum cleaner to clean the appliance.
b.
Gently remove the simulated pebbles, logs or driftwood one by one & remove soot deposits with a soft brush.
c.
The firebed granules should be as shown on the drawing on page 5. If they are not top up as required. Ensure that the granules are
not obstructing the pilot cover assembly. If any further granules are required use only those supplied by Nu-Flame.
d. Pebble, log & driftwood effect fires:
Re-lay as shown on the relevant drawing.
Do not add more simulated pebbles, logs or
driftwood or change the firebed layout in any way.
