CAUTION
LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND
DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER SERVICING.
POWER VENT WIRING SCHEMATIC - FIGURE 19.
2. If the Vent Terminal is being installed on the outside of a finished wall, it may
be easier to mark both the inside and outside wall. Align the holes by drilling
a hole through the center of the template from the inside through to the
outside. The template can now be positioned on the outside wall using the
drilled hole as a centering point for the template.
3. A) MASONRY SIDE WALLS
Chisel an opening approximately one half inch (1.3 cm) larger than
the marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch (0.64 cm) outside of
the marked circle. This pilot hole is used as a starting point for a
saws-all or sabre saw blade. Cut around the marked circle staying
approximately one quarter inch (0.64 cm) outside of the line. (This
will allow the vent to easily slide through the opening. The resulting
gap will be covered up by the Vent Terminal cover plate.) Repeat this
step on inside wall if necessary.
SEQUENCE OF INSTALLATIONS, FIGURE 18
Cut a length of PVC pipe about 3.5 inches (8.9 cm) longer than the wall
thickness at the opening. Glue the vent terminal to this section of pipe. Slide
the wall plate over the pipe to stop against the vent terminal. Place a bead
of caulking (not supplied) around the gap between the pipe and cover
plate. Apply enough to fill some of the gap between the pipe and wall.
Place some of the caulking on the back of the plate to hold it against the
wall after installation. If the vent pipe is installed up to the wall, with a
coupling on the end against the wall opening, the pipe with the vent
terminal can be prepared for gluing before inserting through the wall. Slide
the pipe through the wall and insert into the coupling on the other side of
the wall, making sure that the vent terminal ends up pointed in the correct
position, see Figure 18.
