VENTING YOUR OVEN:

Most jurisdictions consider our low-temperature ovens

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.

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).
