MAINTENANCE18.9.1 Spark electrode• Disconnect the electrode inlet (3) and the grounding cable (2).• Remove the 2 spark electrode retaining screws (4).• Carefully remove the electrode from the combustionchamber.• Check that the extremes of the electrode (6) are notdamaged.• Clean away any accumulation of dirt and check that thedistance between the two electrodes is between 3.5 and 4.5mm.• Check that the gasket (5) is not damaged. Replace ifnecessary.18.9.2 Dismantling the burnerbWarning:The gasket (12) must be replaced eachtime the burner is dismantled.• Disconnect the spark electrode connector (6) from the igniterunit.18.9.5 Re-assembling the burner group• Place the burner group on the heat exchanger (11).• Progressively tighten the 4 nuts (7) in an alternate order.• Reassemble the silencer.• Connect the gas tube (17) with a new gasket to the burnergroup.• Connect the spark electrode connector (6) to the igniter unit.• Connect the connector to the gas valve (1) and the fan (15).• Open the appliance gas input.• Check the watertightness of the gas connection.18.10 Service completion• Re-check the combustion, see chapter "Combustion check".On completion of the service, the "Benchmark" Service Recordsould be completed.• Remove the gas pipe (17).• Remove the connectors from the gas valve (1) and the fan(15).• Remove the retaining screw of the silencer.• Loosen the 4 nuts (7).• Remove the burner group from the heat exchanger (11).• The studs (8) fixed to the heat exchanger must notbe damaged. Should it be damaged, replace the heatexchanger.• The burner gate insulation should not be damaged Replaceif damaged.18.9.3 Cleaning the heat exchanger• Clean the coil (19) in the heat exchanger (11) with water.18.9.4 Burner control• The burner (13) does not require maintenance and shouldnot be cleaned.• Check that its surface is not damage. Replace the burner ifnecessary.• Following the verification or replacement of the burner,assemble the burner group as described in the followingchapter.0020085231_02 - 05/10 - Glow-worm- 45 -
