J. Assemble vent run to exterior wall - If not previously measured, locate the center of the vent at the exterior wall. Prepare an opening as described in Step B. Assemble the vent system to point where the terminus of the last section is located relative to the exterior surface to which the termination is to be attached as shown in Figure 33 and Table 4 on page 18.
If the terminus of the last section is not within this distance, use the telescopic vent section SV4.5LA, as the last vent section. For wall thicknesses greater than that shown in Figure 32, refer to Table 4 on page 18. This table lists the additional venting components needed (in addition to the termination and adapter) for a particular range of wall thicknesses.
K. Attach termination adapter - Attach the adapter (adapter - SV4.5RCH - provided with the termination) to the vent section or tele- scoping vent section), elbow or appliance col- lar as shown in Figure 32 in the same manner as any SV4.5 vent component (refer to Step E).

L. Install Firestop/Spacer at exterior wall - When using the square termination, install SV4.5HF (Secure Vent), SF4.5HF (Secure Flex) Firestop/Spacer over the opening at the exte- rior side of the framing, long side up, with the 3 inch spacer clearance at the top as shown in Figure 32, and nail into place.
(The Firestop/Spacer may also be installed over the opening at the interior side of the framing.)
M. Install the desired termination -
*Use silicone caulking to seal the top and sides of the termination, up to the underlayment, stucco, or masonry wall surface.

SVHRK Snorkel Cap
The vertical distance between the inlet and outlet of the cap is 28 in. (711 mm).
IMPORTANT: The vent termination is hot while in operation and for a period of time following use of the fireplace. To prevent contact with hot surfaces, we recommend the use of a Termination Guard. This can be purchased at your local dealer.

Horizontal Square Termination (SV4.5HT-2).
Figure 33
Horizontal terminations have been designed to perform in a wide range of weather conditions. Our terminations meet or exceed industry standards.
When selecting the locations of your horizontal terminations, do not place the termination where water from eaves and adjoining rooflines may create a heavy flow of cascading water onto the termination cap. If the cap must be placed where the possibility of cascading water exists, it is the responsibility of the builder to direct the water away from the termination cap by using gutters or other means.
Take care to carefully follow the installation instructions for the termination, including the use of silicone caulking where required.
