Installation of a Single Hood (Wall or Island)
The following is a step-by-step procedure for installation of the ventilation hood.
1. Uncrate the hood, being very careful not to dent or scratch the outer surface. NOTE: Report any
damage to the delivering freight carrier and file a claim if appropriate. Refer to the
installation drawing for typical details of the ventilation system prior to hanging the hood. Check
the nameplate on the equipment to make certain it meets the specifications provided by the
architect and/or engineer. If discrepancies exist, notify the manufacturer immediately.
The nameplate will also give information regarding the following:
•
Clearance from cooking surface to front lower edge of the hood
•
Minimum exhaust air flow
•
Maximum supply air flow (if applicable)
•
Minimum front overhang from cooking surface
•
Minimum side overhang from cooking surface
•
Maximum cooking surface temperature
•
Replacing fusible links for exhaust and supply damper (if applicable)
•
Replacing filters
2. Determine the height at which the hood will be hung:
Canopy hoods are typically hung so that the front lower edge of the hood is within 6'6" - 7'0"
AFF. However, the hood should be hung so that the proper clearance from the cooking surface
to the front lower edge of the hood is maintained. See nameplate for clearance from cooking
surface to front lower edge of hood. Exact hood hanging height should be verified with local
authorities having jurisdiction.
Note: If there are wrappers (enclosure panels) with the order, measure down from the ceiling the
height of the wrappers. That will be the top hanging height of the hood as long as the following
criteria are met:
•
The front lower edge of the hood is within 6’6” to 7’0” AFF,
•
The front lower edge of the hood is within the clearance requirement from the
cooking surfaces, and
•
If the hanging height based on wrappers does not fall in this range, contact your local
office.
Backshelf hoods are typically hung at the maximum height allowed from the cooking surfaces.
See nameplate for clearance from cooking surface to front lower edge of hood. Exact hood
hanging should be verified with local authorities having jurisdiction.
Note: If there are wrappers with the order, measure down from the ceiling the height of the
wrappers. That will be the top hanging height of the hood as long as the front lower edge of the
hood is within the clearance requirement from the cooking surfaces. If the hanging height based
on wrappers does not fall in this range, contact your local office.
3. If the hood has a back return, install it now. See the Installation of Hood Accessories section.
4. If the hood has a bolt-together standoff, install it now. See the Installation of Hood Accessories
section.
5. If the hood has duct thermostats, install them now per the thermostat installation drawing.
6. Position hood on the floor in its approximate final position with the supply and exhaust risers on
the hood located directly beneath the corresponding openings in the roof, if possible. It is
advisable to finalize the location using a plumb-bob or laser. Protect the hood when it is on the
jacks to avoid dents, scratches, and other damage to the hood.
7. Proceed to weld exhaust duct to hood while on the floor, if possible.
