The Matrix in the fire is a Moulded Ceramic Fibre component incorporating Silicone Binders and you may notice that it develops cracks
during operation. This is natural shrinkage caused by exposure to high temperatures and is quite normal for the material and will in no way
affect the operation of the fire.

Now remove the Fuel Bed Components and place in a safe location to prevent any damage, taking note of their placement.
j.
If any parts need replacing, use only genuine parts supplied by Nu -Flame Ltd. Some components may look similar to those used in
other gas fire, but these are not necessarily the same due to performance variations and
must not
be used.
This applies particularly to the Flame Failure Pilot System, Gas Control System and Ceramics.

20 - FAULT FINDING GUIDE, SYMPTOMS AND POSSIBLE CAUSES

In instances where it is indicating that the main control system needs changing, (specifically the 2 Remote Control Systems),
you should investigate returning the whole Burner Control System Assembly to Nu-Flame for Rectification as this could be the least cost
option.

b.
Check the supply pressure at the isolation elbow.
c. Important:
With the 2 Remote Control Systems always change the batteries before carrying out any Fault Finding.
20.1 - RESETTING THE HAND HELD RADIO FREQUENCY CONTROL SYSTEMS
Full Reset -
If a new handset is obtained 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 on page 8) has not worked a Full Reset can be carried out:
a.
Open the Controls Door and locate the electronic Receiver Box.
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.
d.
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.
e.
If you hear one long beep the Code as not been set so repeat the procedure.
f.
If the Handset still does not work check the wiring and or replace the Receiver and Handset .
20.2 - NO SPARK IGNITION
a.
Replace the batteries in the receiver and handset.
b.
Check there is no dust/debris shorting out the electrode or blocking the gas from the pilot.
c.
Check the condition of the Ignition lead and ensure it is connected to both the ignition electrode and receiver. Check that the Ignition
lead is not trapped and or shorting, replace if required. For the Manual System this will involve a new control.
