capture smoke, grease-laden vapors, heat, odors,
or fumes.

Low temperature equipment (maximum 2.
temperature 250°F/121°C) does not produce heat,
odors, fumes, grease-laden vapors or smoke and
is not required to be vented.

HOT UNIT SPECIFICATIONS:

All units use three (3) elements (2670 watts each). All units are rated 8200 watts.

Most jurisdictions consider our low-temperature 3.
ovens (maximum temperature is 350°F/177°C) as
low-heat appliances not requiring vent hoods.

Installation must conform with local codes. The 4.
authority having jurisdiction of enforcement of
the codes will have the responsibility for making
interpretations of the rules.
