position.
OPERATING PROCEDURE
1. To Start Kettle Heating:
a. EVERY DAY make sure that the jacket water level in the middle of the sight
glass. If the level is too low, see “Jacket Filling and Water Treatment” in
this manual.
b. Check the pressure/vacuum gauge. If the gauge does not show 20 to
30 inches of mercury (Hg) vacuum (that is a reading of 20 to 30 below 0
atmospheric pressure), see “Jacket Vacuum” in this manual.
c. DO NOT attempt to light any burner with a flame.
d. Open the main supply gas valve (handle in line with the pipe).
e. Turn the switch to ON.
f. Set heat using instructions above.
2. To Stop Kettle Heating:
a. Turn the switch OFF.
b. Turn the manual gas valve OFF (handle a right angle to gas line).
c. Disconnect the units electrical power.
3. To Relight Kettle:
a. Close main gas supply valve.
b. Set on-off switch to OFF.
c. Wait five minutes, then proceed as directed under To Start Kettle Heating.
4. If electric power fails, do not attempt to operate the unit. When power is
restored, proceed as directed in To Start Kettle Heating.
5. To Transfer Product or Empty Kettle:
a. Crank Tilt Kettles: The kettle body is tilted using the crank tilt handwheel.
Turning the crank counter-clockwise tilts the kettle body; clockwise
returns it to an upright position. The kettle body will remain in any tilted
position.
b. Hand Tilt Kettles: The kettle is designed to be tilted in a controlled manner.
Grasp the insulated plastic ball firmly. Maintain a firm grip on the handle
when tilting, keeping the kettle body in a tilted position or SLOWLY
returning the kettle body to an upright position.
Lift the rear of the lid first.
USE OF COMMON ACCESSORIES
1. Lift-Off Cover:
a. As with stock pot cooking, an optional lift off cover will speed up the
heating of water and food products. A cover helps retain heat in the
cooking vessel and reduces the amount of heat and humidity released
into the kitchen. Use of a cover can reduce some product cook times and
help maintain the temperature, color and texture of products being held or
simmered for extended periods.
b. Make sure the plastic ball handle is secure on the lift off cover before
using. ALWAYS use the plastic handle to place or remove cover from the
kettle. Wear protective oven mitts and a protective apron.
c. When putting the cover on the kettle, position it on top of kettle rim, with
its flat edge facing the pouring lip.
d. When removing cover:
1) Firmly grasp plastic handle
2) Lift rear edge (farthest from operator) 1-2” (3-5 cm) to allow any steam
and water vapor to escape the cooking vessel. Wait 2-3 seconds.
3) Tilt cover to 45-60° angle and allow any hot condensate or product to
roll off cover back into kettle.
4) Remove cover, ensuring that any remaining hot condensate or product
does not drip on operator, floor or work surfaces.
5) Place cover on safe, flat, sanitary, out-of-the-way surface, or return to
kettle rim. Cover may also be placed in the optional holder for cover
as shown in the photograph.
2. Basket Insert:
a. An optional kettle basket insert can assist in cooking water-boiled
