NATURAL GAS ONLY Check the gas pressure inlet supply to the dryer, 11 inches WC Pressure maximum. Check the manifold pressure, 3.5 inches WC Pressure inside the dryer. CAUTION Low gas pressure and intermittent gas will cause gas ignition problems and inadequate drying of the clothes load. Page 21 Steam Piping Installation INSTALLATION INSTRUCTIONS PIPING RECOMMENDATIONS 1. Set and anchor dryer in position. Machine should be level to assure proper steam circulation. 2. To prevent condensate draining from headers to dryer, pipingshould have a minimum 12” above respective header. Do not make steam connection to header with a horizontal or downwardly facing tee or elbow. 3. Whenever possible, horizontal runs of steam lines must drain, by gravity, to respective steam header. Water pockets, or animproperly drained steam header will provide wet steam, causing improper operation of dryer. If pockets or improperdrainage cannot be eliminated, install a bypass trap to draincondensate from the low point in the steam supply header tothe return. 4. In both steam supply and steam return line, it is recommendedthat each have a 3/4” union and 3/4” globe valve. This willenable you to disconnect the steam connections and servicethe dryer while your plant is in operation. 5. Before connecting trap and check valve to dryer, open globevalve in steam supply line and allow steam to flow throughdryer to flush out any dirt and scale from dryer. This willassure proper operation of trap when connected. 6. After flushing system, install bucket trap (with built-instrainer) and check valve. For successful operation of dryer, install trap 18" below coil and as near to the dryer aspossible. Inspect trap carefully for inlet and outlet markingsand install according to trap manufacturer’s instructions. Ifsteam is gravity returned to boiler, omit trap but install checkvalve in return line near dryer. 7. Install union and globe valve in return line and make finalpipe connections to return header. 1. Trap each dryer individually. Always keep the trap clean andin good working condition. 2. When dryer is on the end of a line of equipment, extendheader at least 4 feet beyond dryer. Install globe valve, union, check valve and bypass trap at end of line. If gravity returnedto boiler, omit trap. 3. Insulate steam supply and return line for safety ofoperator and safety while servicing dryer. 4. Keep dryer in good working condition. Repair or replace anyworn or defective parts.
