Resumen del manual
11-While supporting ignitor and sensor lines at the grommet, grasp burners and simultaneously pull burners and grommet out of the burner box. 12 -Remove ignitor and sensor bracket assemblies from burners using a 1/4 inch nut driver to remove two screws from each bracket. 13 -Clean burner by running a vacuum with a soft brush attachment over face of burners. Use burner brush to clean inside of burners. Visually inspect inside of burners and crossovers for any blockage caused by foreign matter. Remove any blockage. 14 -Reinstall ignitor and sensor bracket assemblies on burners. NOTE -Ignitor must be installed on the opposite side of the burner from the metal button protrusions. Screws which attached the ignitor bracket must be installed from the same side as the ignitor and through the bracket to engage in the smaller holes located in the burner. The correct burner orientation is with metal button protrusions always pointing up. 15 -Replace burner ignitor assembly back into burner box so that grommet groove fits back into sheet metal notch and makes a good seal. The bumers sit on top of the burner box flanges. Make certain that the screws from underneath the box pass through the larger holes in the flange and engage in the smaller holes in the burner. Reinstall the two screws. 16 -Reinstall the gas manifold/gas valve assembly by first inserting the right hand side of the gas manifold into the burner box. Swing left side of manifold into box while engaging support bracket to vestibule panel screws. Check that foam gaskets are providing a seal around each end of the gas manifold.All gas oririces should be engaged. If at this point the burners were mounted in the wrong holes, this needs to be corrected. The saddle brackets on the gas manifold should be flush with the front surfaces on the burner box sides. 17 -inspect the dual layered metal piecesat the front lip of the cover. These pieces must sandwich around the metal. Reinstall burner box cover. 18 -Reinstallthe screws to secure the burner box cover. Make sure screws are tight to ensure a leak tight burner box. Tighten the two screws underneath the box. Again, inspect the grommet to ensure a tight seal. 19 --tighten the two screws holding the manifold bracket to the vestibule panel. 20 -Reinstallthe electricalconnections to the gas valve. Brown wire to "HI" yellow wire to "C" and orange wire to "M." 21 -Reinstall the 2-pin ignitor plug at the burner box. Reinstall sensor line to ignition control spade connector. 22 -Reconnect gas line to gas valve. 23 -Replace lower access panel. 24 -Following lighting instructions and gas line connection test procedures from installation manual. 25 -Replace upper access panel.
