B. Recommendations

NOTE THAT THE HOOD DIMENSIONS SHOWN IN FIGURE 2-

2 ARE RECOMMENDATIONS ONLY. LOCAL AND NATIONAL

CODES MUST BE FOLLOWED WHEN INSTALLING THE

VENTILATION SYSTEM. ANY APPLICABLE LOCAL AND

NATIONAL CODES SUPERSEDE THE RECOMMENDATIONS

SHOWN IN THIS MANUAL.

The rate of air flow exhausted through the ventilation system may

vary depending on the oven configuration and hood design.

Consult the hood manufacturer or ventilation engineer for these

specifications.

To avoid a negative pressure condition in the kitchen area, return

air must be brought back to replenish the air that was exhausted.

A negative pressure in the kitchen can cause heat- related

problems to the oven components as if there were no ventilation

at all. The best method of supplying return air is through the

heating, ventilation and air conditioning (HVAC) system. Through

the HVAC system, the air can be temperature-controlled for

summer and winter. Return air can also be brought in directly

from outside the building, but detrimental effects can result from

extreme seasonal hot and cold temperatures from the outdoors.

NOTE: Return air from the mechanically driven system must not

blow at the opening of the baking chamber. Poor oven baking

performance will result.

C. Other ventilation concerns

 Special locations, conditions, or problems may require the

services of a ventilation engineer or specialist.

 Inadequate ventilation can inhibit oven performance.

 It is recommended that the ventilation system and duct work

be checked at prevailing intervals as specified by the hood

manufacturer and/or HVAC engineer or specialist.

A. Requirements

CAUTION

 A mechanically driven ventilation system is REQUIRED for

gas oven installations.

 A mechanically driven ventilation system is STRONGLY

RECOMMENDED for electric oven installations.

PROPER VENTILATION OF THE OVEN IS THE

RESPONSIBILITY OF THE OWNER.

II. VENTILATION SYSTEM

IMPORTANT

Where national or local codes require the

installation of fire suppression equip-

ment or other supplementary equipment,

DO NOT mount the equipment directly to

the oven.

MOUNTING SUCH EQUIPMENT ON

THE OVEN MAY:

 VOID AGENCY CERTIFICATIONS
