In the event that the kettle fails to operate correctly, the

difculty should rst be isolated to either the kettle itself

or the steam supply which heats the kettle. While me­chanical problems are obvious faults of the kettle, any de-

ciencies in volume and pressure of the steam should be

traced to the steam generator and the cause determined.
Steam input requirements are listed below. This list rec­ommends delivered boiler horsepower for kettle size and

steam ow.

CABINET EXTERIOR REMOVAL:

Side and rear panels of all cabinets in which kettles are
mounted are easily removed without the use of tools.
Each panel is grasped at the bottom edge and pulled out
sharply to release it from the panel mounting brackets.
Replacement is completed by pushing panel up under
the cabinet top and pressing in at the bottom until panel
mounting brackets are engaged.

Doors may be removed to improve access to cabinet inte­rior for repairs. The two at head screws, nuts, and hold­ing cabinet hinge are removed to lift the door out. When

doors are remounted, the nal tightened position of hinge

determines the alignment of the door and must be set
with care.
