BACKSHELF or PROXIMITY HOOD
is a low-proximity hood, or a wall-mounted sidewall hood that:
(a) is positioned lower in height and depth than a canopy hood;
(b) is set back from the front of the appliance;
(c) is closed to the rear of the appliances by (a) a panel when the appliance is freestanding, or (b) a panel or wall when the appliance is wall mounted, and;
(d) is located above the cooking surface.
This
style of hood can be constructed with partial end panels to increase its
effectiveness in capturing the effluent generated by the cooking operations.
