10. BURNER AND SUPPLY PIPE INSTALLATION10.1 Burner and supply pipe installation.1. Refit the burner unit to the convection box with two screws.2. Connect the supply line to the appliance.3. Turn on the gas supply and pressure check the installation pipework for gassoundness. In the United Kingdom (GB) check in accordance with the current editionof BS 6891. In the Republic of Ireland check in accordance with the current edition ofIS 813 “Domestic Gas Installations”.10.2 Preliminary burner checks.Some burner operations can be checked at this stage. Checking now will mean thatless disassembly will be required if any problems are found. A full check should stillbe made, however, after final installation.1. If closed , open the isolating valve at the inlet ‘T’ connector and replace the endcap.2. Rotate the control pivot bracket clockwise asfar as it will go and hold in this position (Seefigure 27). This should close the ignition circuitand simultaneously open the gas tap allowingthe gas to flow to the pilot. Wait a few secondswhile the air is purged. The electronicallygenerated sparks should light the pilot. Thepilot should then light the main burner at its lowsetting. There may be a delay of up to fourseconds between the pilot lighting and ignition of the gas at the main burner. This isnormal and is due to the time required to fill the main burner compartment withsufficient gas for ignition.3. When the burner is operating properly, gradually turn the control pivot bracket anti-clockwise. The burner flames should gradually increase until the pivot bracket isnearly at its furthest anti-clockwise rotation. Rotating further until the pivot bracketcomes to a stop should then turn the burner and pilot off.4. If the above checks are satisfactory, continue with the installation. If not, check thecontrol and ignition circuitry and components as described in the servicing section ofthis guide.Page 31© Baxi Heating U.K. Limited 2009.INSTALLER GUIDEFigure 27. Control pivot plate
