7.If a wall thimble is used, push the pipe (which is connected to the appliance) carefully through the wall thimble until the DIRECT-TEMP pipe becomes fully engaged 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 termina- tion. 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 termination 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 be- low 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)

Vertical Installation (Fig. 43)

1.Determine the location of the appliance. Choose a location 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 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 satisfy all clearance-to-combustible requirements as specified by the appliance manufacturer’s installation instructions.
