SECTION 2
INSTALLATION
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.
CAUTION
For additional installation information, refer to the PS360 Pre-Installation Procedures Manual (Middleby
Marshall P/N 88210-0024) 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 operation.
NOTE
Wiring diagrams are contained in this manual (Section 5, Electrical Schematics) and are also
located inside the Machinery Compartment Access Panel.
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 guidelines
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
For Australian installation, the oven installation must conform with AGA Code, AG601, and with any requirements of
the appropriate statutory authority.

III. VENTILATION SYSTEM
IMPORTANT
Where national or local codes require
the installation of fire suppression
equipment or other supplementary
equipment, DO NOT mount the equip-
ment 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
A mechanically driven ventilation system is required for the
oven.
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 WILL VARY, AND MUST BE
FOLLOWED WHEN INSTALLING THE VENTILATION
SYSTEM. ANY APPLICABLE LOCAL AND NATIONAL
CODES SUPERSEDE THE RECOMMENDATIONS
SHOWN IN THIS MANUAL.
SECTION 2
INSTALLATION
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 re-
quire the services of a ventilation engineer or special-
ist.
Inadequate ventilation can inhibit oven performance.
It is recommended that the ventilation system and
duct work be checked at prevailing intervals as speci-
fied by the hood manufacturer and/or HVAC engineer
or specialist.

THERMOCOUPLE
INSTALLATION
1. Install the thermocouple sensing bulb into the correct
hole in the rear of the oven, as shown in Figure 2-3.
2. Thread the thermocouple lead through the grommet
and into the machinery compartment.

3. Remove the right-side access panel of the machinery
compartment.
4. Thread the thermocouple lead through the side of the
machinery compartment as shown in Figure 2-4, and
into the electrical box (at the right-front of the machinery compartment).
5. Connect the thermocouple leads to the temperature
controller as shown in Figure 2-5.
6. Repeat Steps 1-5 for each of the other oven sections in
the installation.

V. ASSEMBLY
A. OVEN STAND
If the installation includes upper ovens
mounted atop lower ovens, the ovens
must be stacked before joining the
tandem ovens together.
If the installation includes ovens that
are to be mounted on stands, assemble
the ovens to the stands before joining
the ovens together. An exploded view
of the stand is shown in Figure 2-6.

Oven Stand
For TANDEM and DOUBLE TANDEM installations, perform
Steps 1-8 in this section to join the ovens.
For TRI TANDEM installations, perform Steps 1-8 to join
two of the ovens together, and ensure that they are level;
then, repeat Steps 1-8 to join the third oven to the two that
have already been assembled.
For QUAD TANDEM installations, perform Steps 1-8 for
1. Determine the proper position of the ovens by referring
to Figure 2-7. Then, move the ovens to their approximate
final locations.
2. Check that the top and bottom air finger retaining
screws are present on all mating ends of the oven
sections. See Figure 2-7. The screws prevent the air
fingers from sliding in between the oven sections.
EACH PAIR of ovens, producing two sets of two joined
ovens. Do not assemble the center bridge section at this
time.
