INSTALLATION INSTRUCTIONS (Cont.)
CAUTION
Fan must rotate clockwise when viewed through the oven
door. On three phase motor units, fan rotation can be
reversed by interchanging any two power supply leads.
On single phase units with incorrect fan rotation, contact
factory.
DETAIL B
FLUE CONNECTIONS
Good ventilation, which includes flue connections and
room drafts, is just as important for correct oven operation
as adequate gas supply.
Generally speaking, ovens should never be directly flue
connected, if a direct flue system can be avoided.
The ideal method of ventilating a Convection oven is the
use of a properly designed hood. Hood should extend
about 6" beyond all sides of the appliance. The hood
should be connected to an adequate exhaust duct or
system.
When ovens are installed in locations having low ceilings,
care must be taken to insure proper clearance for the flue
products. Lack of this clearance above outlet of rear flue
piping will interfere with heat circulation in the oven and
could create a fire hazard condition.
Do not permit fans to blow directly at the oven and
wherever possible, avoid open windows adjacent to oven
sides or back and wall type fans which create air cross
currents within the room.
It is also necessary that sufficient room air inlet be
allowed to compensate for the amount of air removed by
any ventilating system. Otherwise, a subnormal
atmosphere pressure will occur, affecting oven operation
adversely and causing undesirable working conditions.
A properly designed and installed hood will act as the
heart of the ventilating system for the room or area in
which the oven is installed, and will leave the oven
independent of changing draft conditions.
