NOTES:
1. Roof curb must be set up for unit being installed.
2. Seal strip must be applied, as required, to unit being installed.
3. Roof curb is made of 16--gauge steel.
4. Attach ductwork to curb (flanges of duct rest on curb).
5. Insulated panels: 1--in. (25.4 mm) thick fiberglass 1 lb. density.
IMPORTANT
: Do not install large base pan HYBRID HEAT
units onto the small base pan (common curb). The center of gravity
on a large base pan HYBRID HEAT unit could overhang the curb
causing an unsafe condition. Before installing any large base pan
unit onto the common curb, check the “Y” distance in the product
literature dimensional drawing to ensure that “Y” is greater than 14
in. (356 mm). Do not install any large base pan unit onto the
common curb with a “Y” dimension (center of gravity) less than 14
in. (356 mm).
