CHAPTER 2: INSTALLATION INSTRUCTIONS
2-2
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.
The 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. 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
in. (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 in. (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,
