CLEARANCE AND VENTILATION
DANGER
No structural material on the fryer should be altered or removed to accommodate
placement of the fryer under a hood. Questions? Call the Frymaster/Dean Service
Hotline at 1-800-551-8633.
DANGER
This appliance must be installed with sufficient ventilation to prevent the occurrence of
unacceptable concentrations of substances harmful to the health of personnel in the
room in which it is installed.
T
he fryer(s) must be installed with a 6" (150 mm) clearance at both sides and back when installed
adjacent to combustible construction; no clearance is required when installed adjacent to
noncombustible construction. If a flue deflector is included with the fryer, ensure that the flue deflector
is installed as per the instruction sheet provided. It is recommended that a flue deflector is used for
fryers installed near a wall cavity that contains combustible materials. A minimum of 24" (600 mm)
clearance should be provided at the front of the fryer.
One of the most important considerations of efficient fryer operation is ventilation. Ensure the fryer is
installed so that products of combustion are removed efficiently, and that the kitchen ventilation system
does not produce drafts that interfere with proper burner operation.
The fryer flue opening must not be placed close to the intake of the exhaust fan, and the fryer must
never have its flue extended in a "chimney" fashion. An extended flue will change the combustion
characteristics of the fryer, causing longer recovery time. It also frequently causes delayed ignition. To
provide the airflow necessary for good combustion and burner operation, the areas surrounding the
fryer front, sides, and rear must be kept clear and unobstructed.
Fryers must be installed in an area with an adequate air supply and adequate ventilation. Adequate
distances must be maintained from the flue outlet of the fryer to the lower edge of the ventilation filter
bank. Filters should be installed at an angle of 45 degrees. Place a drip tray beneath the lowest edge of
the filter. For U.S. installation, NFPA standard No. 96 states, "A minimum distance of 18 inches (450 mm)
should be maintained between the flue outlet and the lower edge of the grease filter.” Frymaster
recommends that the minimum distance be 24 inches (600 mm) from the flue outlet to the bottom edge of the
filter when the appliance consumes more than 120,000 BTU per hour.
Information on construction and installation of ventilating hoods can be found in the NFPA standard
cited above. A copy of the standard may be obtained from the National Fire Protection Association,
Battery March Park, Quincy, MA 02269.
NATIONAL CODE REQUIREMENTS
The type of gas for which the fryer is equipped is stamped on the data plate attached to the inside
of the fryer door. Connect a fryer stamped "NAT" only to natural gas, those stamped "PRO" only to
propane gas.
