with the horizontal termination. If no thimble is used,
place the Trim Plate (TP) on the DIRECT-TEMP pipe.
Carefully push the DIRECT-TEMP pipe through the wall
until fully engaged with the horizontal termination. Se-
cure the trim plate to the wall.
NOTE:
If a vertical rise is necessary on the exterior side
of the building, a 14” (356 mm) and 36” (914 mm) Snorkel
Termination (ST) is available. Follow the installation proce-
dures for horizontal terminations. If the snorkel termination
is to be located below grade, a window well is recommend-
ed with adequate and proper drainage as per local codes.
Leave 2” (51 mm) clearance below snorkel to prevent wa-
ter from entering the snorkel termination. Do not enclose
the snorkel within a wall or other type of enclosure and
do
not back fill
. Ensure that grade level slopes away from the
building. (Figure 39)

1. Determine the location of the appliance. Choose a loca-
tion which provides adequate clearance from obstacles
such as electrical wiring, conduit, framing members,
plumbing pipe, etc.
2. After positioning the appliance, determine where the
vent pipe will pass through the ceiling. This can be done
by using a plum bob or a small weight attached to a

string. Hold the plum bob from the ceiling moving it until
it lines up with the centerline of the outlet of the appli-
ance. Mark the position on the ceiling.
NOTE:
Frame openings to the dimensions specified in the
framing table for the cathedral ceiling support box (CCS),
the ceiling support (SC) and wherever the firestop spacer
(FS) is being used.
3. Cut and frame the appropriate sized square hole through
the ceiling. Repeat the process for other ceiling penetra-
tions as necessary.
4. Determine and mark the roof penetration in the same
manner.
5. Cut a hole in the roof at this point large enough to satisfy
all clearance-to-combustible requirements as specified
by the appliance manufacturer’s installation instructions.
6. Install the ceiling support cathedral ceiling support box
assembly, as appropriate.
7. Determine the distance from the appliance outlet to a
point just above [approximately 12” (305 mm) to 24”
