Principles Of Operation - Dean SM20 Installation & Operation Manual

2.2 General (cont.)
Where conflicts exist between instructions and information in this manual and local code or
national codes, or regulations, installation and operation shall comply with the codes or
regulations in force in the country in which the equipment is installed.
Building codes prohibit a fryer with its open tank of hot oil/shortening from being installed
beside an open flame of any type, including those of broilers and ranges.
Upon arrival, inspect the fryer carefully for visible or concealed damage. (See Receiving and
Unpacking Equipment in Section 2.7.)
Dean appliances equipped with legs are for stationary installations. Appliances fitted with
legs must be lifted during movement to avoid damage to the appliance and bodily injury.
For moveable installations, optional equipment casters must be used. Questions? Call 1-
Dean Super Marathon and Super Runner Series gas fryers are energy efficient, tube-style, gas-fired
units. All units are shipped completely assembled with accessories packed inside the frypot. All
units are adjusted, tested and inspected at the factory before shipment. Sizes and input rates of all
models are listed in this manual.
The on-site supervisor is responsible for ensuring that operators are made aware of
the inherent dangers of operating a hot-oil fryer/filter system, particularly the
aspects of fryer operation, oil filtration, and draining/cleaning procedures.

2.3 Principles of Operation

The incoming gas flows through orifices and is mixed with air in the burners to create the correct
ratio for proper combustion. The mixture is ignited at the front end of each heat tube by the pilot
light. Internal diffusers slow the flame as it goes through the burner tube. This slower and more
turbulent flame gives much better heat transfer to the walls of the tubes, thereby heating the oil more
efficiently.
