LOW WATER LIGHT:

When water needs to be added to the pan, the Low Water

Light will stay on until the pan is refi lled.

INSTALLATION INSTRUCTIONS

VENTING YOUR OVEN:

The purpose of ventilating hoods is to direct and

capture smoke, grease-laden vapors, heat, odors, or

fumes.

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.

1.

2.

Most jurisdictions consider our low-temperature ovens

(maximum temperature is 350°F/177°C) as low-heat

appliances not requiring vent hoods.

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.

3.

4.

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).
