7. If a wall thimble is used, push the pipe (which is con-
nected to the appliance) carefully through the wall thimble
ST932
until the DIRECT-TEMP pipe becomes fully engaged with
Selkirk standoff
the horizontal termination. If no thimble is used, place
6/07
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. Secure 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) Snor-
kel Termination (ST) is available. Follow the installation
procedures for horizontal terminations. If the snorkel ter-
mination is to be located below grade, a window well is
recommended with adequate and proper drainage as per
local codes. Leave 2" (51 mm) clearance below snorkel
to prevent water 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. (Fig. 39)

1. Determine the location of the appliance. Choose a
location which provides adequate clearance from obsta-

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 appliance. 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
penetrations 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 satis-
fy all clearance-to-combustible requirements as specified
by the appliance manufacturer's installation instructions.
