INNOVATIVE HEARTH PRODUCTS • SEE-THROUGH DIRECT-VENT GAS FIREPLACES (DRT63STTEN/P) • INSTALLATION INSTRUCTIONS
It is important to maintain the required clear-
ances to combustibles: 1" (25 mm) at all sides
for all vertical runs; and 4" (102 mm) at the
top, 1" (25 mm) at sides, and 1" (25 mm) at
the bottom for all horizontal/inclined runs.
Use a carpenter's level to measure from a
constant surface and adjust the support straps
as necessary.
J. Assemble vent run to exterior wall.
If not previously measured, locate the center of
the vent at the exterior wall. Prepare an open-
ing as described in Step B (previous page).
Assemble the vent system to point where the
terminus of the last section is within 5 in. (127
mm) to 8-1/2 in. (216 mm) inboard of the
exterior surface to which the termination is to
be attached, see Figure 30 (below) and Table
8 (Page 23).
If the terminus of the last section is not within
this distance, use the telescopic vent section
(SV8LA) as the last vent section. For wall thick-
nesses greater than that shown in Figure 30,
refer to Table 8 on Page 23. This table lists
the additional venting components needed (in
addition to the termination and adaptor) for a
particular range of wall thicknesses.
K. Attach termination adaptor.
Attach the adaptor (adaptor - SV8RCH - provided
with the termination) to the vent section or
telescoping vent section), or elbow as shown in
Figure 29 in the same manner as any SV vent
component (refer to Step E, previous page).
L. Install Firestop/Spacer at exterior wall.
When using the square termination, install
Secure Vent™ Firestop/Spacer (SV8HF4) over
the opening at the exterior side of the framing,
long side up, with the 4-inch spacer clearance
at the top as shown in Figure 29, and nail
into place.
M. Install the Square Termination (SV8HTS4).
For the last step, 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) as shown in Figure 30.
IMPORTANT: The vent termination is hot
while in operation and for a period of time
following the use of the fireplace. Young
children should be carefully supervised
when they are in the same area as a hot
termination.

Horizontal terminations have been designed to perform in a wide range of weather condi-
tions. Our terminations meet or exceed industry standards.
When selecting the locations of your horizontal terminations, do not place the termina-
tion where water from eaves and adjoining rooflines may create a heavy flow of cascad-
ing 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 these installation instructions for the termination, including
the use of silicone caulking where required.
