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.

UNIT SPECIFICATIONS: All units use six (6) elements (2000 watts each).
All units are rated 12000 watts.

(maximum temperature is 350°F/177°C) as low-heat
appliances not requiring vent hoods.

the codes will have the responsibility for making
