The recommended exhaust volumes are based on the specifications from the
2009 International Mechanical Code Section 507.13.1 (Extra Heavy Duty
Cooking Appliances, Single Canopy, 700 CFM per linear foot of hood). Wall-
mounted hoods will require less volume (550 CFM per linear foot). These
drawings specify a 12 inch hood overhang at the front oven doors and the side
containing the fire box door with a 6 inch overhang on the non-active sides (no
oven or firebox doors).
For proper design of a hood over our ovens, please refer to
Figure 5A
(
Figures 5 and 5A depict a single canopy hood design).
It is very
important that the filter bank be located toward the rear of the
unit (near the chimney connector). This simulates the natural-draft of a
chimney above the chimney connector for which these units were engineered
to control both temperature and smoke.
