Superior DR-400 Installation Instructions Manual page 15

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
31 , refer to table 3 on page 16 . This table lists
the additional venting components needed (in
addition to the termination and adapter) for a
particular range of wall thicknesses.
When using long square (SV4.5HTSSL)
horizontal termination -
Assemble the vent system to point where the
terminus of the last section is within 0 in. (0
mm) to 9 in. (248 mm) inboard of the
exterior surface to which the termination is to
be attached, see Figure 32 .
K. When using square (SV4.5HTS) or short
square (SV4.5 HTSS) horizontal termination
- attach termination adapter -
Attach the adapter (adapter - SV4.5RCH - pro-
vided with the termination) to the vent section or
telescoping vent section), elbow or appliance
collar as shown in Figure 29 in the same manner
as any SV4.5 vent component (refer to Step E).
L. Install Firestop/Spacer at exterior wall -
When using either of the square terminations,
install SV4.5HF (Secure Vent), or 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 29 or 30 , and nail into place.
(The Firestop/Spacer may 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 termi-
nation has integral spacers which provide the
same function as a separate firestop/spacer.
*Note - Firestop/Spacer
(SV4.5HF) required, but
not shown for clarity.
