Carry out the operations in 23.1 General before proceeding
! IMPORTANT NOTE !
TAKE GREAT CARE WHEN WORKING INSIDE THE FIRE NOT TO MARK THE CERAMIC
LINING PANEL IF THEY HAVE NOT BEEN REMOVED.
a. Checking in the opening of the Burner Box if a build-up of Debris is found that cannot be easily removed through the opening then
the Battery Cassette and Burner Box will need to be removed, see below.
i. Working at the left side lift up the Battery Cassette Assembly by pulling upward on the tabs inside and set aside.
Ii. Now to the right lift upward and remove the large Burner Box Assembly (complete with Burner Tray Assembly).
b. Now remove any Debris and replace in reverse order ensuring that when the Battery Cassette Assembly is refitted the foam strip
seals up against the side of the Burner Box.
Note : If the Debris volume indicates a flue problem then this should be corrected before continuing.
c. Brush clean the burner and pilot area of dust or debris; check that the aeration hole in the pilot is clear of dust, fluff, lint.
Note : It is quite normal to see shrinkage cracks on the Burner Pad on the edges of the Flame Slots.
d. Refit in reverse order brushing the fuel effect pieces clean of any soot, checking gas soundness, ignition and spillage as detailed
in the relevant sections.
ALWAYS CONDUCT A GAS SOUNDNESS AND SPILLAGE 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 CONTROL SYSTEM IS WORKING CORRECTLY. (This accounts for a lot of recalls.)
24. - FAULT FINDING GUIDE, SYMPTOMS AND POSSIBLE CAUSES
FAULT FINDING ADVISE
Important : In instances where it is indicating that the main control system needs changing you should investigate returning the
whole Burner Control Assembly to Nu-Flame for rectification as this could be the least cost option.
IGNITION SEQUENCE
Important : Prior to conducting any Fault Finding it is important to know the Ignition Sequence, see at which stage the
sequence is failing and note the options that can be carried out. The sequence is as follows:
a.
After operating the Handset as detailed in Section 2 an audible ‘ clunk ‘ is heard indicating the Pilot Gas Solenoid as opened.
b. The Pilot Igniter will then start to spark, followed by a pilot flame and the sparking will continue until the thermocouple as
generated the electrical output required. This as a limited time so if the output is not sufficient the pilot solenoid will ’ clunk ’ shut.
With new Installations or a Serviced fire there may be air in the gas pipeline affecting the Pilot Flame size. Repeat the operation.
c. The Control Motor will then be heard turning the Control mechanism and when it reaches its maximum position you will hear
another ’ click ’ indicating the main gas solenoid as opened and the main burner will light.
24.1 - GENERAL
a. Prior to carrying out any of the following steps ensure that you have carried out the procedures in Section 23.1 General
(Servicing) to the appropriate level as required.
b. Check the supply pressure at the isolation elbow.
c. Important : With the Thermatronic RF System always change the batteries before carrying out any Fault Finding.
It is important to know the ignition sequence prior to conducting any Fault Finding.
24.2 - RESETTING THE HANDSET (Every Handset as a unique code that the Receiver needs to learn)
a. Replace the Batteries in both the Battery Box 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 20seconds press and hold down 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.
d. If the Handset still does not work then check the wiring and or replace the Receiver and Handset (if not a New Handset).
In instances where it is indicating that the some or all of main gas control system need changing you should discuss the situation
with Nu-Flame’s Service Department to determine the least cost option.
24.3 - NO SPARK IGNITION
a. Replace the batteries in the Battery Box and Handset.
b. Check that the Emergency Switch at the right is set at ‘ I ‘ . Then operate the switch a number of times before resetting.
c. Check the position of the Radio Frequency Antenna, it should be pointing vertically upward.
d. Check there is no dust/debris shorting out the electrode or blocking gas from the pilot.
e. Check the condition of all leads specifically the Ignition lead and ensure it is connected securely to both the ignition electrode
and the pilot Electrode.
f. Check that the Ignition lead is not trapped and or shorting, replace if required.
g. Check that gas is flowing from the pilot during the ignition sequence. Clean or Replace as required.
h. Main Gas Control - listen to the control to hear if the pilot gas solenoid is opening. Change the Receiver, and the Handset at the
same time and/or gas control. Refer to Diagram for Cable connections in Section 24.
24.4 - PILOT GOES OUT AFTER FIRST LIGHTING
a. Check the steps a) to b) in the last Section 23:1.
b. Check there is no debris blocking the flame to the thermocouple and that the flame is playing on the thermocouple. Change pilot
as required.
c. Check the thermocouple connections are tight.
d. Change the pilot assembly as a new thermocouple may be required.
e. Also see Section 23.4
f. Change the Receiver, wiring and the Handset at the same time and/or the gas control.
Refer to Diagram for Cable connections on in Section 24.
In instances where it is indicating that the some or all of main gas control system need changing you should discuss the situation
with Nu-Flame’s Service Department to determine the least cost option.
