DIRECT FLUE ARRANGEMENT
When the installation of a mechanically driven exhaust
hood is impractical the oven may be vented by a direct
ue arrangement.
WARNING!!
It is essential that the direct ue be installed
as follows. Incorrect installation will result in
unsatisfactory baking and oven damage.
The ue must be class B or better with a diameter of 6”
(15 cm). The height of the ue should rise 6-8 ft (2-2.5 m)
above the roof of the building or any proximate structure.
Never direct vent the oven into a hood. The ue 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 sufcient 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.
Installing the draft hood
Ovens ordered for direct venting are supplied with a draft
hood. Install the draft hood as follows:
1. Place the draft hood over the ue connector.
2. Secure both ends with the sheet metal screws pro-
vided.
