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.
