When the motor is started, the exhaust fan pulls air in through louvers at the rear of the dryer and over the heat source (burner flame for gas and heating element for electric). The heated air moves through the heater duct and into the cylinder, where it circulates through the wet load. The air then passes through the lint filter, air duct, and exhaust fan, where it is vented to the outdoors. 505872 © Copyright, Alliance Laundry Systems LLC – DO NOT COPY or TRANSMIT 7 Section 3 Troubleshooting WARNING To reduce the risk of electric shock, fire, explosion, serious injury or death: • Disconnect electric power to the dryer(s) before servicing. • Close gas shut-off valve to gas dryer(s) before servicing. • Never start the dryer(s) with any guards/panels removed. • Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the dryer is properly grounded.

Turn the gas line shut-off valve handle to the open position and connect electrical service. Refer to Figure 48. l. Check gas valve pressure as follows: (1) Remove pressure tap pipe plug. Refer to Figure 48. (2) Connect a “U” tube manometer (or similar pressure gauge) to the pressure tap. Refer to Figure 49. (3) Start dryer, pressure should be 3.5 ± .2 inches (8.9 ± .5 cm). Refer to Figure 49. (4) Stop dryer and remove “U” tube and reinstall the pressure tap pipe plug. Refer to Figure 48. m. Check the gas line connection for gas leaks with a soapy solution. n. Make sure the dryer conversion has been completed. Recheck the following: (1) Installed correct orifice spud (#40), see step “e”. (2) Installed vent screw, see step “g”. (3) Gas valve pressure must be 3.5 ± .2 inches (8.9 ± .5 cm), see step “l”. (4) Installed four stickers, see steps “h”, “i”, and “j”. o. Start the dryer and observe the burner flame. Adjust air shutter to obtain a soft, uniform flame. (A lazy, orange tipped flame indicates lack of air. A harsh, roaring, very blue flame indicates too much air.) Adjust the air shutter to obtain a soft uniform blue flame as follows: (1) Loosen the air shutter lockscrew. Refer to Figure 49. 505872 MANOMETER AIR SHUTTER LOCKSCREW 3.5 ± .2 INCHES DR058-SV-1 AIR SHUTTER GAS VALVE PRESSURE TAP Figure 49 (2) Turn the air shutter to the right or left as necessary to obtain proper flame intensity. (3) After air shutter is adjusted for proper flame, tighten air shutter lockscrew firmly. p. Be sure and observe at least two complete ignition and burn cycles before reinstalling the access door. q. Reinstall the access door.
