Installation & Operation Manual
5.9.4. HOOD INTERCONNECTION
The following is a recommended method of providing an interlock system, (if required); between the
ventilation fan in the hood and the XLT gas ovens.
The circuit shown will stop the ovens from operating if the ventilation fan fails and also prevent the ovens
from starting if the ventilation fan is not first operating.
It is recommended that the fan interlock switch be located on the ventilation fan itself rather than the
motor to prevent a false run signal in the case of a broken fan drive belt.
It is the customer’s responsibility to have the interlock system installed by a licensed electrician and that
it meets all required local codes.
See oven rough-in requirements for receptacle requirement.

5.9.5. FIRE SUPPRESSION
On the XLT series of convection ovens, the heat source is located in an isolated heat exchanger
area. Due to this isolation, convection style conveyor ovens do not fall under the same fire
suppression requirements as commercial cooking devices that do expose products to direct flame
.
CAUTION:
Always use the proper oven shut down procedure for turning ovens off. Do
not turn off ventilation fan until cool down sequence on oven is completed.
The use of the ventilation fan control to shut off ovens manually, may void
warranty on ovens
