FIGURE 5 - Roof Curb and
Duct Opening Dimensions
IMPORTANT NOTES: Area enclosed by roof
curb must comply with clearance to combustible
materials. If the roof is constructed of combustible
materials, area within the roof curb must be
ventilated, left open, or covered with non-
combustible material which has an "R" value of
at least 5. If area within curb is left open, higher
radiated sound levels may result.
If area inside curb is open, roof opening
dimensions must be no greater than:
Cabinet A - 34-13/16" x 69" (884 x 1753mm);
Cabinet B - 49-13/16" x 69" (1265 x 1753mm);
Cabinet C - 61-5/16" x 97-7/8" (1557 x 2486mm).
