DIRECT FLUE ARRANGEMENT

When the installation of a mechanically driven ex- 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 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 sec- tion. To increase the supply air entering the room, a ventilation expert should be consulted.
