INSTALLATION INSTRUCTIONS
VENTING YOUR OVEN:
3. Most jurisdictions consider our low-temperature ovens
(maximum temperature is 350°F/177°C) as low-heat
appliances not requiring vent hoods.
4. Installation must conform with local codes. The
authority having jurisdiction of enforcement of
the codes will have the responsibility for making
interpretations of the rules.

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

UNIT SPECIFICATIONS: All units use three (3) elements (2670 watts each).
All units are rated 8200 watts. Water units have one (1) immersion element (1850 watts).
