12. Apply weatherproof sealant to the seam between the AFR
fan housing and primary ashing. This seam must be sealed
to create a weatherproof barrier between the fan and the
ashing. (see Figure 2.2G)
NOTE: This seam exists to allow the use of interchangeable
ashings. If this seam is not sealed, water may leak in
between the fan housing and the ashing. Be sure to use
a generous amount of weatherproof sealant to create a
watertight seal.
13. Using the QuietCool Secondary Flashing accessory (part
number FLA-SEC-3743), gently slide the ashing over the fan
housing and hood mounting tabs. (see Figure 2.2H)
NOTE: The secondary ashing was designed to work with
almost all types of tile and cement roofs. The ashing can
be molded to create the shapes of more unique style roofs
such as S-Tile and M-Tile.
NOTE: Be sure that the secondary ashing extends onto
the roof tile at the bottom of the ashing. This ensures that
water cannot leak in between roof tiles.
15. Form the secondary ashing to close the gap between the
ashing and the fan housing. The aluminum is very malleable
so this should be done easily using your hands. Using
weatherproof sealant, seal the gap between the fan housing
and secondary ashing. (see Figure 2.2I)
16. Bend the left and right side edge of the secondary ashing
at a 90º angle to create a water channel on either side of the
ashing. This will help direct water to ow down and back onto
the roof rather than side to side under the tiles. (see Figure
2.2J)
17. Using an angle grinder, cut the removed tiles to t them to the
shape of the fan and secondary ashing. (see Figure 2.2K)
18. Re-install the tile around the fan unit. (see Figure 2.2L)
19. Apply weatherproof sealant on the bottom side of the
secondary ashing to secure the ashing to the roof tile.(see
Figure 2.2M)
20. Re-install the hood onto the fan unit and remove the
protective lm.
