All models are designed for AC Service. Model numbers may have the letters: P, L, M, Z, T or S.
VENTING YOUR OVEN: The purpose of ventilating hoods is to direct and 1. capture smoke, grease-laden vapors, heat, odors, or fumes.Low temperature equipment (maximum temperature 2. 250°F/121°C) does not produce heat, odors, fumes, grease-laden vapors or smoke and is not required to be vented.
Most jurisdictions consider our low-temperature ovens 3. (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.
