Changing Components – Page 8
Before changing any components please read the
Important Information Section on page 2.
The following components can be removed as described below
after first removing the outer case. Turn off the gas and
withdraw the plug from the electrical supply before removing the
outercase.
ENSURE THAT THE FIRE IS COLD
GAS CONTROL TAP
(Flame Failure Device)
(a)
Greasing the tap plug
(Fig. 13). Pull off the plastic cap
and then the spark electrode lead from the piezo unit and
undo the two set screws and washers securing the niting
plate to the tap body.
Remove the piezo unit complete with the gas tap spindle
and spring. Now remove the plug and apply suitable
grease sparingly, e.g. Kluber N322B. (Excessive grease
may block the gasways). On re-assembling care must be
taken to ensure that both the plug and spring are in place.
(b)
To exchange the component
(Fig. 11). (Disconnect the
gas supply and remove the fire from the fireplace.) Pull off
the plastic cap and disconnect the spark electrode lead
from the piezo unit. Disconnect the four tubes at the gas
tap. Disconnect the thermocouple from the gas tap.
Remove the 3 screws securing the gas tap bracket to the
inner case and remove the complete assembly. Remove
the locknut holding the gas tap to the bracket and remove
the gas tap.
On re-assembly ensure that the spark electrode lead is correctly
fitted and that the plastic cap is pushed on the piezo unit.
Ensure that the pilot filter supplied with the new tap is fitted.
GLASS FRONT PANEL
(Fig. 10)
(a)
Ensure that the glass front panel is cold.
(b)
Slide the glass front panel retaining clamps sideways.
(c)
Lift the glass front panel bottom edge out of the locating
channel and carefully remove the glass front panel.
On re-assembly ensure that:
(a)
The glass front panel sealing rope is replaced if it is in
anyway damaged.
(b)
The glass front panel is replaced if it is in anyway
damaged or cracked.
NOTE: This is a heat resistant glass front and must not be
replaced by ordinary glass.
COAL BED
(Fig. 10)
Remove the glass front panel as described above.
Remove the coal bed by lifting it carefully away from the
locating pins.
CAUTION: The coal bed is extremely fragile and must be
handled accordingly. Gloves should be worn and any
inhalation of the dust should be avoided. Keep the coals
away from children at all times. Please read the
Important Information Section on page 2.
On re-assembly ensure that the coal bed is correctly located
over the locating pins.
BURNER
(Figs. 10,11 and 12)
(a)
Remove the glass front and coal bed as described above.
(b)
If fitted, remove the screw holding the pilot shield to the
burner rail.
(c)
Remove the screw holding the pilot assembly to it’s
bracket.
(d)
Disconnect the compression nuts from the injectors.
(e)
Remove the two screws securing the burner.
(f)
Ease the pilot assembly forwards and slide the burner out
above the glass locating channel.
(g)
Remove the injectors from the burner.
PILOT/THERMOCOUPLE/ELECTRODE
ASSEMBLY
(Fig. 12)
NOTE: The thermocouple cannot be changed as an
individual component. The complete assembly must be
changed in the event of one or other component failure(s).
(a)
Disconnect the gas supply and remove the fire from the
fireplace.
(b)
Pull back the sleeve and disconnect the lead from the
electrode.
(c)
Undo the nut on the pilot feed pipe.
(d)
Remove the screw holding the assembly to the bracket.
(e)
Undo the thermocouple from the gas tap.
(f)
Remove the assembly from the fire.
(g)
On re-assembly, shape the thermocouple in a similar
manner to the original.
ELECTRO MAGNETIC UNIT
(Fig. 11 and 13)
(a)
Remove the gas tap as explained in Gas Control Tap
section (b).
(b)
Remove the electro magnet retaining nut and withdraw the
electro magnet unit.
PIEZO UNIT
(Fig. 13)
(a)
Pull off the plastic cap and disconnect the spark electrode
lead from the piezo unit.
(b)
Undo the tabs on the rear of the piezo unit and remove.
(c)
Replace the piezo unit twisting the tabs to retain it firmly in
position. Re-connect the spark electrode lead and re-fit the
plastic cap.
RESISTOR
(a)
Check that the mains lead is disconnected.
(b)
Remove the screw securing the light bulb cover and lift
upwards.
(c)
Remove the clip securing the resistor to the cover and
disconnect the 2 wires.
(d)
Replace the Resistor and reassemble in reverse order.
LIGHT SWITCH
Pull off the two flag terminals from the switch noting their
relative positions. Press together the retaining arms on the rear
of the switch and remove from the bezel. Replace the switch
and terminals.
