Installer).
It is recommended that the flue is checked for debris.
Turn off the gas supply before commencing any servicing.
After any servicing ALWAYS check for gas soundness

At yearly intervals, turn off and allow to cool down. Check
all coals, pilot burner/ignition burner unit, for soot/debris
deposits. These can cause imperfect flame appearance
and should be removed by lightly vacuuming. Replace all
misplaced coals and re-light.
NOTE: On failure of either the pilot burner/ignition unit or
main control valve, repairs should be carried out by a
competent person.
For LPG Appliances Only
Because of the nature of L.P. Gases, there could be
excessive soot particles deposited on the refractories,
therefore it is recommended that this should be checked
at six monthly intervals, by turning off and allowing to
cool down. Check all coals, pilot/ignition unit for soot or
debris deposits. These can cause imperfect flame
appearance and should be removed by lightly vacuuming.
