II. VENTILATION GUIDELINES
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.
