SFHRK Snorkel Cap
–The snorkel cap is de-
signed to be fitted into a basement window box.
The SFHRK cap is for use with flex vent pipe.
Vertical distance between the inlet and outlet of
the cap is 28 in. (711 mm).
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 within 7
¹⁄₂
in. (191 mm) to 11
³⁄₄
in. (298 mm)
inboard of the exterior surface to which the
SV4.5 HTS termination is to be attached, see
Figure 36
. 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 35
, refer to
table 3 on page 18
. This
table lists the additional venting components
needed (in addition to the termination and
adapter) for a particular range of wall thick-
nesses.
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 35
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 35
, 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 ter-
mination has integral spacers which provide
the same function as a separate firestop/spacer.
1. Install the square termination
(SV4.5HTS)-
For the last step , from outside
the exterior wall, slide the collars of the termi-
nation onto the adapter until the termination
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 re-
cessed 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 37
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 seats against the exterior wall sur-
face 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 SV4.5HTR Round Ter-
mination may not be used when the appliance
is vented directly out the wall from the side as
shown in
Figure 36
. Do Not recess the SV4.5HTR
round termination at all
.
