7.5 AIR VENTING INSTRUCTIONS
Check vacuum/pressure gauge when the kettle is cold. Gauge should be in the green
vacuum zone, indicating a vacuum between 25-30 In. Hg (630 - 730 mm Hg). If not, air
must be vented (removed) for proper heating. Use the following procedures to vent air.
1. Place power switch ON with kettle empty.
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.
(Located on back of kettle, before pressure relief valve.)
WARNING: SCALD HAZARD. Live steam will escape the bleed nut
when opened. Stay clear of live steam when performing this
operation.
4. Cool kettle. Check for proper vacuum in green area of gauge. If vacuum was not
established, repeat steps 1 - 4.
