INSTALLATION INSTRUCTIONS
VENTING YOUR OVEN:
1. The purpose of ventilating hoods is to direct and
capture smoke, grease-laden vapors, heat, odors,
or fumes.
3. Most jurisdictions consider our low-temperature
ovens (maximum temperature is 350°F/177°C) as
low-heat appliances not requiring vent hoods.
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.
