B. Recommendations

NOTE THAT THE HOOD DIMENSIONS SHOWN IN FIGURE 2-

2 ARE RECOMMENDATIONS ONLY.  LOCAL, NATIONAL AND

INTERNATIONAL  CODES  MUST  BE  FOLLOWED  WHEN

INSTALLING THE VENTILATION SYSTEM.  ANY APPLICABLE

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

Gas  oven  installations  REQUIRE  a  mechanically  driven

ventilation system with electrical exhaust air sensing control.
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

• RESTRICT  SERVICE  ACCESS

• LEAD  TO  INCREASED  SERVICE  EX-

PENSES FOR THE OWNER
