DIRECT FLUE ARRANGEMENT
When the installation of a mechanically driven exĆ
haust hood is impractical the oven may be vented
by a direct flue arrangement.
WARNING!!
It is essential that the direct flue be
installed as follows. Incorrect installation
will result in unsatisfactory baking and
oven damage.
The flue must be class B or better. The height of
the flue should rise 6Ć8 ft (2Ć2.5 m) above the roof
of the building or any proximate structure. Never
direct vent the oven into a hood. The flue should
be capped with a UL Listed type vent cap to isolate
the unit from external environmental conditions.
The direct vent cannot replace air consumed and
vented by the oven. Provisions must be made to
supply the room with sufficient makeĆup air. Total
makeĆup air requirements for each oven section
should be approximately 30 CFM (.85 m
3
) per secĆ
tion. To increase the supply air entering the room,
a ventilation expert should be consulted.
