For LGBT'" 13-23, the universal igniti, <br />produces a spark to ignite the pilot on the second base. After the pilot(! <br />flame safeguard control energizes the main flame circuit allowing the magi uurrrera w iyrIILe dL <br />low fire. The main pilot is then de -energized and the main flame sensor proves the main burner <br />operation at low fire. For LGBT" 13-23, the pilot on the second base continues to burn during <br />the boiler "on" cycle. The flame safeguard control then energizes the downstream gas valve <br />allowing the boiler to fire at high fire. <br />If the pilot or main flame are not proven during the start-up sequence, then the flame safeguard <br />control will lock out on safety. A red indicator light and alarm bell will energize. The lockout <br />condition should be corrected and then the red reset button should be pressed to restart the <br />boiler. The control system will permit a normal start up after an automatic 5-minute delay. <br />The control system has been certified by AGA and all components are UL Listed. <br />16-gauge panel finished <br />in Weil -McLain blue <br />Hinged front cover <br />(may be removed <br />if necessary) <br />Key lock on <br />front cover <br />Wiring diagrams and <br />operating sequence <br />included in pocket <br />Reset <br />button <br />r1, ��i(til (I<Vrr � I,�tii.drG <br />i1 yh_ i n,�,� �ii(, �;(Jill.roll nni Iii`i,11,r <br />()v(o4110Ih k vv hn-(r nrrav <br />ennp7 (line(- 1P <br />VrVr1'r� „i''a Jri,(i��t I(r ii n,,, .r(iiiirrV4. <br />in <br />r Ir°, <br />Ample knockouts (top and Fuse protection <br />(spare furnished) <br />Color -coded bottom) to meet any installation <br />105°C wires I d <br />(one a[ top, <br />two at bottom) <br />7 <br />Recessed indicator lights <br />and switches for <br />maximum protection <br />Removable Lexan lenses <br />with easily replaced <br />incandescent bulbs — <br />no dimming <br />Light indicates flame <br />failure <br />" Quick -disconnect <br />type connectors <br />Knockout for field <br />application of additional <br />switches <br />Conveniently numbered Wide terminal block <br />tubular screw connectors spacing for ease <br />of wiring <br />
