NOTE: 

 DO  NOT  install  top  panel  onto  double  or  triple 

 

ovens  until  AFTER  stacking  the  oven  cavities.  See 

Part B, Stacking.

B. Stacking

For  single  ovens,  skip  ahead  to  Part  C,  Restraint  Cable 

 

Installation.

IMPORTANT

Middleby Marshall STRONGLY RECOMMENDS that PS740 

Gas oven cavities be stacked BY AUTHORIZED PERSONEL.

Contact your Middleby Marshall Authorized Service Agent for 

complete stacking instructions.
1.  Stack an oven cavity on top of the lower oven. Check  

the following:

•  All four sides of the lower lip (on the bottom edge of 

the oven cavity) overlap the top of the lower oven

•  The oven is level

•  The oven is firmly seated

 

See Figure 2-9.

2.   For  triple  ovens,  repeat  Step  1  to  install  the  top 

 

oven cavity.

3.  Install the top panel using the screws included in the base 

pad kit, as shown in Figure 2-10.

C.  Restraint Cable Installation

Because the oven is equipped with casters, a restraint cable 

assembly must be installed to limit the movement of the appli

-

ance without depending on the connector and the quick discon-

nect device or its associated piping. One end of the cable is 

anchored to the eyebolt on the rear surface of the oven’s base 

pad, while the other is anchored to the wall.  See Figure 2-11.
After connecting the restraint cable, move the oven to its final 

location. Adjust the bottom (hex) sections of the feet so that 

 

the  casters  are  off  the  floor.  For  quad  ovens,  lock  the  two 

 

front casters.
