All models : Firstly, remove the decorative
frame/glass facia assembly as described in section
8.3. Remove the inner glass panel, and disconnect the
gas connection inside appliance.The gas connections
to the gas valve can now be released. Detach the
burner front cover plate by removal of the four
retaining screws (as shown in figure 9, section 8.2).
Remove the control knob and spindle by pulling out-
wards.
Classic and Linear models : To remove the outer
casing (sides and top), remove the four retaining
screws designated ‘a’ in figure 13. Pull the casing for-
ward slightly and then lift the entire casing assembly
upwards and remove.
Fab models : To remove the right hand casing side
panel, remove the two screws shown in figure 15,
then pull the right hand side forward and then side-
ways. Note - to remove the burner it is only neces-
sary to remove the right hand side panel.The same
method is used should it be necessary to remove
the left hand panel.
All models : To remove the burner, undo the two
screws retaining the burner support bracket (desig-
nated ‘b’ in figure 13) to the base and rear of the fire-
box, and undo the four retaining screws on the right
hand side panel, near the control valve as shown in
figure 14.The burner may now be removed.
Remove the pilot and main burner pipes and blow
through to dislodge any debris. Now remove the
restrictor elbow and blow through to make sure it is
entirely clear. Unclip the pilot lint gauze and clean
with a soft brush. Clean the exterior of the pilot
assembly with a soft brush and blow through the
flame ports on the pilot head. Check the aeration
holes are free from lint or dirt. The pilot assembly
can be removed if required by disconnecting the
electrode HT lead, gas pipe and unscrewing the mounting screws and lifting away.
The pilot assembly is a non-serviceable item and should not be taken apart. Aeration holes
must be absolutely clear internally for proper operation. NEVER MODIFY OR BEND
THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT. Modifications are
dangerous and can have serious unseen effects on safety. If the pilot will not stay lit there is a problem with dirt, the gas supply
to it, or the thermocouple needs replacement.
The gas valve is a non-serviceable item. If this needs replacement, remove M4 securing screw holding the valve in place, remove
all pipe unions, electrode lead, thermocouple lead and then the complete valve. Replacement must be original manufacturers parts.
Re-assembly is the reverse of removal. Ensure setting pressures are as stated in Section 2; Appliance Data.
Clean the pilot assembly with a soft brush and blow through. Check the aeration holes are free of any dirt or lint. Clean thor-
oughly internally, the connection can be removed from the base of the pilot unit using two spanners to make cleaning easier. Do
not damage or try to dismantle the pilot injector.
The unit is factory set and the only check necessary is to ensure the spark gap is correct. See specifications for gas setting.
NEVER MODIFY OR BEND THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT. If the pilot will not stay lit there
is a problem with dirt, the gas supply, or the thermocouple needs replacement. Modifications are dangerous and can have a seri-
ous unseen effect on safety and therefore MUST not be done. Replacements must be original manufacturers parts. Re-assemble
in the reverse of removal. Ensure setting pressures are as stated in Section 2;Appliance Data.
