DIRECT FLUE ARRANGEMENT
When the installation of a mechanically driven exhaust hood is impractical the oven may be vented by a direct flue arrange
-
ment.
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 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 make-up air. Total make-up air requirements for each oven section should be approximately 30 CFM (.85 m3) per
section. To increase the supply air entering 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 flue connector.
2. Secure both ends with the sheet metal screws provided.
