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 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.

secure to the framing members with nails or screws (Figure 23).
NOTE: Proper venting support is very important. Never use the fireplace to support the weight of the venting.
in the same manner as the straight vent sections. The elbows feature a twist section to allow them to be routed
about the center axis of their initial collar section to align with the required direction of the next vent run element.
Twist elbow sections in a clockwise direction only so as to avoid the possiblity of unlocking any of the previously
connected vent sections (Figure 20).
sections in horizontal/inclined run. Install support straps every 5 ft. (1.52 m) along horizontal/inclined vent runs
using conventional plumber's tape or catalog number SV4.5SU (Figure 27). 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 support straps
as necessary.
Maintain the required clearances to combustibles (Page 24).
exterior wall. Prepare the opening. Assemble the vent system until the terminus of the last section is within
5" (127 mm) to 8 1/2" (216 mm) inboard of the exterior surface to which the SV4.5 HT termination is to be
attached (Figure 28). 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 21 lists the additional venting components needed (in addition to the
termination and adaptor) for a range of wall thicknesses.

Vent), SF4.5HF (Secure Flex) Firestop/Spacer over the opening at the exterior side of the framing, long side up,
with the 3" spacer clearance at the top (Figure 28) and nail into place.
NOTE: The firestop/spacer may also be installed over the opening at the interior side of the framing.
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 29).
NOTE: If the venting exits the building below grade, or close to grade, see Installation Accessories on
Page 50 for available snorkel terminations. The termination must be above grade and above the expected
level of snow accumulation.
NOTE: The vent termination is hot while in operation and for a period of time following the use of the fireplace.
To prevent contact with hot surfaces, use a horizontal termination guard; available for purchase at your
local dealer.
