19 - SERVICING
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.
19.1 - GENERAL
Note: Servicing must be carried out by a registered installer.
a.
The fire does not have to be removed for Servicing.
b.
Check the operation and ignition of the fire before servicing.
c.
Ensure the fire is cold before proceeding.
d.
Lay a dust sheet on the floor before proceeding.
e.
Carry out a gas soundness test before servicing.
f.
Remove case by opening the Controls Door and then firstly remove the 2 screws at the left and right sides. Secondly lift the case up at
the back and remove. Place in a convenient place with the 2 screws.
g.
Turn off the gas supply to the fire at the isolation/pressure test elbow.
h.
Remove the 5 special countersunk screws holding the glass door panel, slide it downward to remove, check for any damage.
i.
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.
k.
Disconnect the gas pipe to the control.
IMPORTANT: Always Lay The Case Down To Prevent It Being Damaged.
19.2 – ANNUAL SERVICING

2 at the back and front.
Carefully lift the Burner Assembly upward then roll out from the back to remove, taking care not to Mark the Liners.
This will now allow access to all gas carrying parts for maintenance checks, fault finding and or replacement.
l.
Brush clean the burner and pilot area of dust or debris; check that the aeration hole in the pilot is clear of dust.
m.
Refit in reverse order; brushing the Coals/Woods clean of any soot, checking gas soundness and ignition as detailed in the relevant
Sections.

exchange the Batteries in both the Handset and Receiver.
q.
With the 2 Remote Control Systems ensure they are operational with the Handset.
ALWAYS CONDUCT A GAS SOUNDNESS CHECK AFTER SERVICING.
ALWAYS RESEAL THE PRESSURE TEST POINT AND CHECK THAT IT IS GAS TIGHT.
(This accounts for a lot of recalls.)
ALWAYS CHECK THAT THE GLASS IS CLEAN AND FREE FROM FINGERPRINTS.
(This accounts for a lot of recalls.)
IF THERE IS ANY DAMAGE FOUND ON THE GLASS PANEL IT MUST BE REPLACED BEFORE THE FIRE IS USED.
Note: Marks on the Glass Panel are Not Covered by the Manufactures Warranty.
20 - FAULT FINDING GUIDE, SYMPTOMS AND POSSIBLE CAUSES
Important:
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.
a.
Prior to any Servicing ensure that you have carried out the procedures in Section 19.1 General (Servicing).
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.
c.
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.
d.
Check the condition of the Electrode, if it sparks intermittently it may be cracked, replace.
