VENTING INSTALLATION
Continued
Figure 9 - Installing the Horizontal Termination
9. Continue installation of horizontal/inclined sections
—
Continue with the installation of the straight vent sections
in horizontal/inclined run. Install support straps every
5 ft. (1.52 m) along horizontal/inclined vent runs using
conventional plumber’s tape (Figure 8, page 14). Maintain
the horizontal/inclined run in a straight (no dips), slightly
elevated plane. The recommended incline is approximately
1/4” per 1 ft (20 mm per 1 m) horizontal, in a direction
away from the fireplace. Smaller rise per foot run ratios are
acceptable all the way to at or near level. Use a carpenter’s
level to measure from a constant surface and adjust the sup-
port straps as necessary. Maintain the required clearances
to combustibles (Page 9).
10. Assemble the vent run to the exterior wall
—If not previ-
ously measured, locate the center of the vent at the exterior
wall. Prepare the opening. Assemble the vent system until
the terminus of the last section is within 7” (178 mm) to
11 1/4” (286 mm) inboard of the exterior surface to which
the SV4.5 HT termination is to be attached (Figure 9). If the
terminus of the last section is not within this distance, use
the telescopic vent section SV4.5LA, as the last vent section.
Table 1, page 16 lists the additional venting components
needed (in addition to the termination and adaptor) for a
range of wall thicknesses.
11. Attach the termination adaptor
—Attach the adaptor
(SV4.5RCH, provided with the termination) to the vent sec-
tion or telescoping vent section, elbow or fireplace collar
(Figure 9).
12. Install the firestop/spacer at the exterior wall
—When us-
ing the square termination, install SV4.5HF Firestop/Spacer
over the opening at the exterior side of the framing, long
side up, with the 3” spacer clearance at the top (Figure 9)
and nail into place.
NOTE:
The firestop/spacer may also be installed over the
opening at the interior side of the framing.
13. Install the termination (SV4.5HTKCT)
—From outside the
exterior wall, slide the collars of the termination onto the
adaptor (the outer over the outer and the inner inside the
inner) 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 recessed into the exterior wall or siding by more
than the 1 1/4” (32 mm) (Figure 10, page 16).
NOTE:
The vent termination is hot while in operation and for
a period of time following the use of the fireplace. To pre-
vent contact with hot surfaces, use a horizontal termination
guard; available for purchase at your local dealer.
The 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 ad-
joining 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.

be installed on the exterior
side of the wall.
