INSTALLATION AND OPERATION MANUAL, DIRECT STEAM TILTING KETTLES, MODELS: DWT-20, 30, 40, 60, 80, 100 7.0 TROUBLESHOOTING DRAW-OFF VALVE LEAKS If a leak occurs through the valve steam, replace the “O” ring. If the leak can be attributed to faulty sealing occurring between the stem disc and valve seat, then quite often this problem can be corrected by cleaning off the dried on food residue with an extremely fine emery cloth or the rubber vulcanized stem piece has been damaged and must be replaced.
Page 14 INSTALLATION AND OPERATION MANUAL, DIRECT STEAM TILTING KETTLES, MODELS: DWT-20, 30, 40, 60, 80, 100 7.0 TROUBLESHOOTING AIR VENTING It is recommended that the “optional” steam trap assembly be installed. This should be plumbed to the exit end of the kettle. The thermostatic trap is a mechanical device that closes on high temperature and opens when the temperature drops, allowing the water which formed from condensate to exhaust but retain the steam under pressure.
