Type I hood termination location?

[mtlogcabin]

Question within the office. We have a store with a Type I hood in the deli that would like to terminate out the sidewall located adjacent to a public 20 ft wide alley versus going through 2 stories to the roof. Some believe the 10 foot requirement does not apply to a public ROW others believe it does because there is a property line for the alley (city property)

Opinions please

2009 IMC

506.3.12.3 Termination location.

Exhaust outlets shall be located not less than 10 feet (3048 mm) horizontally from parts of the same or contiguous buildings, adjacent buildings and adjacent property lines and shall be located not less than 10 feet (3048 mm) above the adjoining grade level. Exhaust outlets shall be located not less than 10 feet (3048 mm) horizontally from or not less than 3 feet (914 mm) above air intake openings into any building.

Exception: Exhaust outlets shall terminate not less than 5 feet (1524 mm) from parts of the same or contiguous building, an adjacent building, adjacent property line and air intake openings into a building where air from the exhaust outlet discharges away from such locations.

If the property line is there, then the vent shouldn't be (unless the exception applies).

Is it possible install the duct on the exterior, terminating at or above the roof?

I had to get two of them - discharging into a confined space village ROW - relocated, which was much fun as you might imagine.

I say no because there's a P/L issue.

I am assuming the building is on the P/L and then they would be encroaching into the ROW. While it would solve the problem the ROW issue could be a different story in the future.

If teh product they are going to cook is boiled in oil, there are UL listed fryer/recirculating hoods availble from Auto Fry, Giles and other providers. Make sure the device is listed and meets the UL 197 requirement, including the fire suppression system. Usually the fire suppression is not complete and needs to have a licensed contractor finish the installation and test the equipment. I have seen several Auto Fry and Giles set ups that never have had the suppression system activated.

Not part of the ICC codes, but is part of NFPA 17 and NFPA 96, is service after the installation. Someone has to change the fan belt and clean the exhaust system. Even on an exterior duct, listed access panels need to be installed and the fan is to hinge. If the duct is inside the walls, listed access panels need to be installed in the wall and in the duct.

Well said fg, however, just an fyi, the ICC, in this case the IMC does require installation, service and maintenance of the hood, ductwork, listed/rated access panels, motors, fans, etc. Section 506 of the 2006 IMC covers all of these items you listed as only in the NFPA 17 & 96.
