1. Cut 5 1/2” diameter holes through the roof and ceiling directly in line
with the flue 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 flue pipe in the roof jack assembly to a length
that will project at least 6” below the finished 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 flue
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” below the finished 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 flashing tilts up to 22.6° degrees for use on a sloping
roof.
5. Use sealant or caulk on the roof to seal under flashing 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.
FIGURE 15.
NOTE: An optional Roof jack Extension Pipe (9002588) is required when
the roof pitch is 5 1/2” 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” woven tape seal
(found attached to the heater top) and apply the seal around the flue
collar of the water heater, see Figure 16 on page 12.
