INSTALLATION INSTRUCTIONS
VENTING YOUR OVEN:
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.
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.
