603.8.1 Slope. Ducts shall have a minimum slope of 1 / 8 inch per foot (10.4 mm/m) to allow drainage to a point provided with access.

Ducts shall be installed with not less than 2 percent slope on horizontal runs up to 75 feet (22 860 mm) and not less than 8 percent slope on horizontal runs more than 75 feet (22 860 mm). Factory-built grease ducts shall be permitted to

2021年10月19日 · Unlike pipes though you can’t model ducts with a pre-determined slope, you can only join from connector to connector using the “Change Slope” and “Inherit Elevation” tools, per your other post.

Duct systems serving a Type I hood shall be constructed and installed so that grease cannot collect in any portion thereof, and the system shall slope not less than one-fourth unit vertical in 12 units horizontal (2-percent slope) toward the hood or toward a grease reservoir designed and installed in accordance with Section 506.3.7.1. Where ...

The value for the slope control at the center of the duct indicates the rise/run, angle, percentage or ratio for the slope, depending on the Slope parameter for the HVAC discipline in the Project Units dialog. Click the angle at the midpoint of the duct. The angle flips to point to the opposite end of the duct. Setting an absolute slope

2016年7月7日 · In the real Project you have many situation then you need ducts with slope like Kitchen and many other Exhaust system and etc. As you see in the below picture when you run Duct command in Revit you can’t find any option for create duct system with slop

Ducts shall have a minimum slope of 1 / 8 inch per foot (10.4 mm/m) to allow drainage to a point provided with access. Ducts shall be sealed, secured and tested prior to concrete encasement or direct burial. Ducts shall be leak tested as required by Section C403 of the International Energy Conservation Code.

Anyone familiar with the requirements for grease ducts in NFPA96 and the various mechanical codes is aware of the fact that horizontal grease ducts are required to include 1⁄4” per foot slope in order to reduce the likelihood of grease pooling in horizontal runs …

In long horizontal ducts, a slope is required of 6.4 mm (0.25 in.) over 305 mm (12 in.). Additionally, it must drain into an approved grease reservoir. In some areas a pitch of 1 inch may be required with accompanying approved sumps. Check local by-laws for these requirements.
