SECTION 2 - INSTALLATION
WARNING
Keep the appliance area free and clear of combustibles.
WARNING
Do not obstruct the flow of combustion and ventilation air to and from your oven. There must be no
obstructions around or underneath the oven.
ENGLISH
CAUTION
For additional installation information, refer to the following documents:
PS360 Pre-Installation Procedures Manual (Middleby Marshall P/N 88210-0024)
PS360 Installation Manual (Middleby Marshall P/N 88210-0025)
Or, contact your local Authorized Service Agent.
NOTE
There must be adequate clearance between the oven and combustible construction. Clearance
must also be provided for servicing and for proper operation.
NOTE
An electrical wiring diagram for the oven is located inside the machinery compartment.
NOTE
All aspects of the oven installation, including placement, utility connections, and ventilation requirements, must
conform with any applicable local and national codes. These codes supercede the requirements and guide-
lines provided in this manual.
NOTE
In U.S.A., the oven installation must conform with local codes, or in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1. The oven, when installed, must be electrically grounded in accordance
with local codes, or in the absence of local codes, with the National Electrical Code (NEC), or ANSI/NFPA70.
NOTE
In Canada, the oven installation must conform with local codes, or in the absence of local codes, with the
Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Gas Installation Code, CAN/CGA-B149.2, as
applicable. The oven, when installed, must be electrically grounded in accordance with local codes, or in the
absence of local codes, with the Canadian Electrical Code CSA, C22.2, as applicable.
NOTE

II. VENTILATION SYSTEM
IMPORTANT
Where national or local codes require the installation of fire
suppression equipment 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 EXPENSES FOR THE
OWNER
A. Requirements
CAUTION
A mechanically driven ventilation system is RE-
QUIRED 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.
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 heatrelated problems to the oven components as if there were no
