Installation

CAUTION

UNIT MUST HAVE AIR VENT PLATES

INSTALLED OR WARRANTY WILL BE VOID.

A mechanically driven ventilation system is required for the PS528 Series Middleby Marshall conveyorized gas ovens.

Local codes and conditions vary greatly from one area to another and must be complied with. Following are the suggested requirements for good ventilation. Please remember these are recommendations or guidelines, you may have a special condition or problem that will require the services of a ventilation engineer or specialist. Proper ventilation is the oven owner’s responsibility. Improper ventilation can inhibit oven performance.

Please Note: There are now two “stand off” ‘C’ Chan- nels and “Heat Guards” for “Double and Triple Ovens”

that must be installed in the field.

Please Note: There is now one heat guard on dou- ble units and two heat guards on triple units. See Figure 2-7.

These ‘C’ Channel brackets are installed in the vertical plane using existing screws (Item 6) to support these ‘C’ Channels using the upper and lower Key Hole openings in the ‘C’ Channels. The ‘C’ Channels are identical and once installed will allow ample amounts of air through the cooling fan mounted on the rear side of the oven by keeping the oven away from the rear wall.
