Valor Fires 761 Installation And Owner's Manual

11. BURNER AND SUPPLY PIPE INSTALLATION11.1 Burner and supply pipe installation.1. Remove the ‘Aeration checking’ reminder label from the top of the burner.2. Refit the burner unit to the convection box with the two screws removed previously.3. Connect the supply line to the appliance.4. If closed , open the isolating valve at the inlet ‘T’ connector.5. 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”.11.2 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.2. Rotate the control pivot bracket clockwise as far as it will go and hold in thisposition (See figure 24). This should close the ignition circuit and simultaneously openthe gas tap allowing the gas to flow to thepilot. Wait a few seconds while the air ispurged. The electronically generated sparksshould light the pilot. The pilot should thenlight the main burner at its low setting. Theremay be a delay of up to four secondsbetween the pilot lighting and ignition of thegas at the main burner. This is normal and isdue to the time required to fill the mainburner compartment with sufficient gas forignition.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.5. Align the hole near the bottom of the control linking bar with that in the control pivotbracket. Join them with the knurled shouldered screw removed previously.© Baxi Heating U.K. Limited 2008.
