4.0 Roof Curbs for PreevA ® Models RDH, REH, RHH, and RXH (cont'd)
DIMENSIONS
** Dimensions for Model RXH above do not apply to a Model RXH with a hot water heat module. For dimensions with a hot water
heat module (Option HW2), see chart onf page 23.
IMPORTANT NOTE -
Models RDH, REH, and
RXH with Hot Water
Heat: The area enclosed
by the roof curb must
comply with clearance to
combustible materials.
If roof is constructed of
combustible materials,
the area within the curb
must be either ventilated,
left open, or covered
with non-combustible
material which has an
“R” value of at least 5.0.
If the area within the
curb is left open, higher
radiated sound levels
may result.
*Configuration may also include an evaporative cooling module. The evaporative cooling module does not affect the length of the
roof curb.
