The following servicing procedure is recommended in order to cover all aspects of the
appliance to ensure safe and correct operation of the appliance:
Protect the floor area around the appliance to avoid damage when laying out the component parts.
Open the decorative trim frame & unscrew the fixing screws holding the trim backer to fire, lift backer
off and place to one side.
The trim may be cleaned with a damp cloth.
Remove the outlet grille by removing the 3 retaining screws. Clear away any dust or debris from the
openings using a soft brush and vacuum. Place to one side.
Remove the 3 screws in the catalyst vent panel (Fig. 3) and remove the glass panel by lifting the vent
panel slightly and withdrawing the glass from the lower location point. The glass panel can be cleaned
using hot water and a mild non - abrasive detergent. Check the glass for damage and
replace in if
necessary.
Carefully withdraw the catalyst vent panel and examine the condition of the two catalysts both from
the top and from inside the unit. If any damage or cracking of the catalysts is evident, replace.
DO NOT ALLOW THIS APPLIANCE TO BE OPERATED WITH DEFECTIVE CATALYSTS.
Carefully remove the ceramic fuel bed components. These components are extremely fragile. Examine
the condition and check for signs of damage or cracking.
Replace if necessary.
Using suitable
respiratory equipment, clean the components with a soft brush or vacuum with a brush attachment to
prevent dust spread.
Examine the condition, and check for cracking of the back panel and side cheeks of the combustion
chamber surround.
Replace if necessary.
NOTE - Unless replacing component parts, it is not necessary to remove the burner control system
from the appliance, as all components are serviceable without the need for further dismantling.
Undo the gas supply pipe at 8 mm compression fitting at the gas inlet pressure test point elbow.
Remove the two screws from the rear log retaining platform and slide out the complete burner and
control assembly (Fig. 4)
Remove the four retaining screws of the front log / glass locating platform and withdraw. This allows
total access to the burner and control components (Fig. 12)
Examine the tubular burner for any signs of damage.
Replace if necessary.
Ensure all ports
(particularly the ladder ports in front of the pilot assembly) are clear of dust and debris. Clean using
only a soft brush and vacuum with brush attachment. Ensure the large aeration ports in the injector
end of the burner are dust free and clear.
The main burner injector of this appliance should not normally require attention unless there is
evidence of particular flame reduction or excessive dust and debris within the aeration ports of the
burner. If examination is necessary, return to point No. 9 and refer to parts replacement section 14.
Check the pilot assembly and clear it of any dust or debris using a soft brush. Ensure the aeration hole
is clear. Check the condition of the thermocouple and the ceramic spark electrode and wire for any
damage or deterioration. If there are any signs of damage the full pilot assembly will need replacing.
Replace if necessary.
