FLUE CONNECTION
Ventilation requirements will vary with each installation and must comply with
Vapor Removal from
Cooking Equipment
, NFPA Standard #96 (latest edition) and with local codes. Considerations to be
kept in mind include:
Flue connections should never be made directly to the oven.
The oven should be located under a hood which has an adequate connection to an exhaust duct
and extends 6"
(15 cm) beyond the oven sides.
Clearance above the oven flue should be adequate for the flue products to escape so that there
is no interference with the heat circulation in the ovens.
