the assembled pipe to the appliance. Determine and mark the location of where the support collar will be at- tached 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.

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 ter- mination height and with the appliance manufacturer’s installation instructions. (Fig. 45)

NOTE: Whenever DIRECT-TEMP penetrates through a ceiling, a floor or a wall, it must be firestopped.

12. Using a level, make sure the system is perfectly

vertical.

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

ares of the flashing base with roofing material. How-

ever, be sure the lower unnailed portion of the base

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 (2) 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.

15. Install the vertical termination (VC) 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 (2) #8 x 1/4” sheet

metal screws. The screws should be approximately 3/4”

from the bottom of the vertical termination’s galvanized

collar.
