1. Cut 5 1/2” (13.97 cm) diameter holes through the roof and ceiling
directly in line with the fl ue connection on top of the water heater.
For a sloped roof, the roof hole may have to be enlarged to allow
the roof jack to be installed vertically.
2. Telescope down the fl ue pipe in the roof jack assembly to a length
that will project at least 6 inches (15 cm) below the fi nished ceiling
before installing the roof jack assembly.
NOTE: Flue pipe joints have silicone seals that must remain in place.
A soapy water solution sprayed around the seal area will enable the
fl ue pipe and outer pipe below to telescope more freely.
3. Telescope down the outer pipe of the roof jack assembly to a length
that will project at least 2” (5.08 cm) below the fi nished ceiling
before installing the roof jack assembly, see Figure 14.

4. Ease the roof jack assembly through the roof and ceiling openings.
The roof jack fl ashing tilts up to 22.6° degrees for use on a sloping
roof.
5. Use sealant or caulk on the roof to seal under fl ashing of the roof
jack assembly. Use roof nails or screws on wood construction or
sheet metal screws on metal roofs (nails and screws not provided),
see Figure 15.

NOTE: An optional Roof jack Extension Pipe (9002588) is required
when the roof pitch is 5 1/2” (13.97 cm) or greater, or where local
codes require the roof jack cap (outlet) terminate above the peak of
the roof.
6. Remove the paper backing from the 1 1/2” x 9 3/4” (3.81 cm x 24.77
cm) woven tape seal (found attached to the heater top) and apply
the seal around the fl ue collar of the water heater, see Figure 16
