Troubleshooting
Draw-Off Valve Leaks
If leak occurs through the valve stem, replace the "O" ring. If the leak can be attributed to faulty sealing occurring between
the stem disc and valve seat, then this may be due to dried on food residue. Clean the dried on food residue with an
extremely fine emery cloth. If the rubber vulcanized stem piece has been damaged it must be replaced.
Draw-off valve has a vulcanized rubber coated stem for better sealing. Do not over tighten. This may cause the
rubber to pull away from stem and permanently damage it. This is not covered under warranty.
VENTING INSTRUCTIONS
Check vacuum/pressure gauge when the kettle is cold. Gauge should be in the green vacuum zone. If not, air must
be vented (removed) for proper heating. Use the following procedures to vent air.
1. With the kettle empty, place power switch in ON position.
2. Set temperature control thermostat to '10'. Heat kettle until indicator light goes off.
3. Using a 7/16" wrench, open bleed vent one full turn for 10 seconds and then close.
4. Cool kettle. Check for proper vacuum in green vacuum zone. If reading is not low enough, repeat entire
procedure, steps 1 - 4.
Draw-off valve has a vulcanized rubber coated stem for better sealing. Do not over tighten. This may cause the
rubber to pull away from stem and permanently damage it. This is not covered under warranty.
