inserting three #8 x 1/4’’ sheet metal screw through the Support
Collar and the outer wall of the pipe.
9) From above, lower the assembled pipe sections down
through the Cathedral Ceiling Support Box or Ceiling Support
Plate and attach it to the appliance adapter. The Support Collar
should then be adjusted so that when the assembled lengths of
pipe are attached to the appliance, it rests on the bottom of the
Cathedral Ceiling Support Box or on top of the Ceiling Support Plate.
10) Tighten the tabs of the collar. Secure the Support Collar by
7) Determine the distance from the appliance outlet to a point
just above (approximately 1 to 2 feet) either the Cathedral
Ceiling Support Box or the Ceiling Support Plate and
assemble lengths of pipe to satisfy this distance. Do not
attach assembly to appliance.
8) Loosely position the Support Collar around the assembled
lengths (flared end down).
15) Install the Vertical Termination (VC or VT) by inserting it
down into the top most section of pipe until it is fully seated.
Depress lock tab to secure the cap to the pipe. NOTE: In high
wind areas, it is recommended to screw Termination to the pipe
with two #8x1/4” sheet metal screws. The screws should be
approximately 3/4” from the bottom of the Vertical Termination’s
galvanized collar. 0015204-88015204-1009
14) Position the Storm Collar around the pipe and slide down
until it is in contact with the Flashing. Secure the Storm Collar
by inserting the two tabs into the raised slots and fold tabs
back. Seal the area between the Storm Collar and the vent pipe
with a silicone sealant to prevent rain infiltration.
13) Slide the Flashing, suitable for the roof pitch, down over the
pipe protruding through the roof. Recheck orientation and use a
silicone sealant around and under the perimeter of the flashing
where it is in contact with the roof. Secure the flashing with
roofing nails. Finish roofing around the pipe, covering the sides
and upper areas of the Flashing base with roofing material.
However, be sure the lower unnailed portion of the base covers
the roofing material.
12) Using a level, make sure the system is perfectly vertical.
NOTE: Whenever DIRECT-TEMP penetrates through a ceiling,
a floor or a wall, it must be firestopped.
11) Add lengths of pipe and firestop as necessary until
assembly extends to a point above the roof which complies
with local code requirements for minimum termination height
and with the appliance manufacturer’s installation instructions.
See FIG. 14.
NOTE: If the Cathedral Ceiling Support Box Assembly is being
used, it may be necessary to temporarily connect the
assembled pipe to the appliance. Determine and mark the
location of where the Support Collar will be attached to the
pipe. Disconnect and remove assembled pipe. Attach the
Support Collar per step 10 (where marked) and reinstall
assembly. This is due to limited space within the Cathedral
Ceiling Support Box. Install any required Offset Supports.
