6.0 VENTING INSTRUCTIONS
Check vacuum/pressure gauge when kettle is cold. Gauge should be in the vacuum zone
between 25 - 30 In. Hg (84 - 100 kPa). If not, air is present which must be vented (removed) for
proper heating. Use the following procedures to vent air:
1. Place power switch in ON position; kettle empty.
2. Set temperature control thermostat to ‘10'. Heat kettle until heat indicator light goes off.
3. Using a 7/16" wrench, open bleed vent one full turn for 10 seconds and close.
4. Cool kettle. Check for proper vacuum of 25 - 30 In. Hg (84 - 100 kPa). If reading is not low
enough, repeat entire procedure, steps 1 to 3.
7.0 TILTING INSTRUCTIONS
Your kettle has the standard “Clean Lock” feature and may not be tilted without disengaging the
tilt knob located on the console at the top right. This feature locks the kettle in the upright
position and also allows the operator to lock the kettle at 105 degrees for ease of cleaning. To tilt
the kettle the full distance, the tilt lock knob must be disengaged from the cleaning position by
pulling out the tilt lock knob and tilting the kettle forward the full distance. Follow these steps to
tilt kettle:
1. Pull out the tilt knob at top right located on console.
2. Using kettle tilt handle pull kettle forward to desired angle of pour or until kettle locks at 105
degrees. The tilt knob can be released after the kettle has been tilted approximately 10
°.
3. Kettle will lock in position at 105 degrees and may be tilted further by pulling the tilt lock knob
a second time allowing the kettle to tilt the full distance.
4. To return the kettle to the upright position, pull out the tilt lock knob and tilt the kettle upward
until it locks in the upright position. The kettle should not move in either direction once in the
upright position.
