Model
TDH and TDHC models are stainless steel, steam-jacketed, table top mounted kettles
with a self-contained, gas heated steam source. The TDHC has a crank tilt hand wheel,
and the TDH has a handle that allows the operator to manually tilt the kettle. The kettle
body is welded into one solid piece and furnished with a reinforced rim and weldedin “butterfly” shaped pouring lip. The interior of the kettle is polished to a 180 emery
grit finish, and the exterior is given a bright high buff finish. The unit is A.S.M.E. shop
inspected and registered with the National Board for a design pressure of 50 PSIG.
The self-contained steam source is heated by propane or natural gas and is
equipped with electronic ignition. Charged at the factory with chemically pure water
containing rust inhibitors, the steam source provides kettle temperatures of 150ºF to
approximately 295ºF.
Controls for the TDHC unit include a crank tilt handwheel, thermostat, pressure gauge,
pressure relief valve, low water cut-off, On/Off switch, indicator lamp, gas regulator
valve, and water level sight glass. Controls for the TDH are the same as the above,
with the exception of the crank tilt hand wheel.
The gas supply shuts off automatically when the kettle is tilted.
The unit must be specified for use with natural gas or propane. For other gas types,
consult factory. Service connections are required for gas and 115V electricity.

5. To Transfer Product or Empty Kettle:
a. “Classic” or “Advanced” Crank Tilt Kettles: The kettle body is
tilted using the crank tilt handwheel. Turning the crank counterclockwise 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.
6. Use of Common Accessories
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 be-
fore 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.

Basket Insert:
a. An optional kettle basket insert can assist in cooking water-boiled
products including eggs, potatoes, vegetables, shell fish, pasta and
rice. The nylon mesh liner must be used when cooking product
smaller than the mesh size of the basket, which is approximately
1/4” (6 mm). This includes rice and small pasta shapes.
b. Tips For Use:
1) Allow for the water displacement of the basket and product
to be cooked. This may mean only filling the kettle half full
of water. Test the basket and product displacement with the
kettle OFF, and with cold water in the kettle.
