The blower must be sealed between the roof or wall and the underside of the flange with
mastic to prevent leaks. For installation on a flat roof, or a roof with a pitch of less than
2:12, install the blower on a curb as shown below. Position the curb on flat roofs so that
the discharge (low) end points away from the prevailing wind.
