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.
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.
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.
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).
