II. VENTILATION GUIDELINES
A mechanically driven ventilation system is recommended for
the PS528 Series Middleby Marshall conveyorized electric
ovens.
Local codes and conditions vary greatly from one area to
another and must be complied with. Following are the sug-
gested 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’ Channels
that must be installed in the field (See
Section 6: PARTS
LIST
, page 44-45 for reference, Item 5).
