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

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 33 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 exterior side of the framing, long side up, with the 3 inch spacer clearance at the top as shown in Figure 34, and nail into place. (The Firestop/Spacer

may also be installed over the opening at the interior side of the framing.) When using the round termination, a separate firestop/spacer is not required since this termination has inte- gral spacers which provide the same function as a separate firestop/spacer.
M. Install the desired termination -
See the horizontal venting figures for appli- cation restrictions on the round termination (SV4.5HTR) and the small square horizontal termination (SV4.5HTSS).
1. Install the square termination (SV4.5HTS) |
or (SV4.5HTSS)- For the last step , from outside |
the exterior wall, slide the collars of the termina- |
tion onto the adapter (the outer over the outer |
and the inner inside the inner) until the termina- |
tion seats against the exterior wall surface to |
which it will be attached. Orient the housing of |
the termination with the arrow pointed upwards. |
Secure the termination to the exterior wall. The |
horizontal termination must not be recessed |
into the exterior wall or siding by more than the |
1 ¹⁄₄" (32 mm) as shown in Figure 34. |
2. Install the round termination (SV4.5HTR) |
– See Figure 35 for an illustration of the round |
termination. For the last step, from outside the |
exterior wall, slide the collars of the termination |
onto the adapter (the outer over the outer and |
the inner inside the inner) until the termination |

The SV4.5HTR Round Termination may not be used when the appliance is vented di- rectly out the wall from the rear (as shown in Figures 36 or 37 on page 17). Do Not recess the SV4.5HTR round termination at all.
