FIGURE 13.
A certifi ed roof jack (vent kit) from the manufacturer must be
installed with the water heaters covered by this manual. Roof jack
kits are ordered separately. See Figure 13 to determine which roof
jack is needed for the installation.
NOTE: An optional Roof jack Extension Pipe (9002588005) is required
when the roof pitch is 5-1/2” (14 cm) or greater, or where local codes
require the roof jack cap (outlet) to terminate above the peak of the roof.
IMPORTANT: DO NOT common vent this water heater with any other
appliance.
1. Cut a 5-1/2” (14 cm) diameter hole 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” (15.24 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 cm) below the fi nished ceiling before
installing the roof jack assembly. See Figure 14.
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.
