DIRECT FLUE ARRANGEMENT
When the installation of a mechanically driven exhaust
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 6-8 ft (2-2.5 m) above the roof of the build-
ing 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 environ-
mental conditions.
The direct vent cannot replace air consumed and vented
by the oven. Provisions must be made to supply the room
with sufficient make-up air. Total make-up air require-
ments for each oven section should be approximately 30
CFM (.85m3) per section. To increase the supply air en-
tering the room, a ventilation expert should be consulted.
