INSTALL PROBE ASSEMBLY ON THE FIREPLACE
• Attach the probe assembly to appliance. The probe assembly (# 11
from Parts List) is of the same design as the unitized concentric pipe
components of the SV4.5 Secure-Vent System, featuring positive twist
lock connections (see Figure 4 ).
CAUTION: The probe assembly must be installed directly to the ap-
pliance collar. Install the probe assembly first before connecting any
other vent components to the fireplace.
All of the appliances that can be installed with this power vent kit, are
fitted with collars having locking inclined channels. The dimpled end of
the probe assembly fits over the appliance collar to create the positive
twist lock connection.
To attach the probe assembly to the appliance collar, align the dimpled
end over the collar, adjusting the radial alignment until the four locking
dimples are aligned with the inlet of the four inclined channels on the
collar (refer to Figure 4 ). Push the probe assembly against the collar
until it fully engages, then twist the probe assembly clockwise, running
the dimples down and along the incline channels until they seat at the
end of the channels. The unitized design of the probe assembly com-
ponents will engage and seal both the inner and outer pipe without the
need for sealant or screws.
• Attach vent components to the probe assembly. Other vent sections
may be added to the previously installed probe assembly in accordance
with the requirements of the fireplace installation instructions and the
vent charts provided in the instructions.

BEGIN VENTING
Horizontal (Outside Wall) Termination System
NOTE: The LPVK-110 Power Vent system can only be terminated
horizontally.
Various horizontal venting configurations are possible for use with
these power vent kit. Secure Vent pipe are used in these applications.
Refer to Figures 2, 3 and Tables in Figure 3 which summarizes each
system’s minimum and maximum vertical and horizontal length values
that can be used to design and install the vent components in a variety
of applications.
Horizontal vent systems terminate through an outside wall. Building
Codes limit or prohibit terminating in specific areas. Refer to local codes
and Figure 5 for location guidelines.
• Plan and execute the vent run -
Analyze the vent routing and determine the types and quantities of sec-
tions and elbows required. Vent sections are available in net lengths of
4-1/2” (114 mm), 10-1/2” (267 mm), 22-1/2” (572 mm), 34-1/2” (876
mm) and 46-1/2” (1181 mm). Plan the vent lengths so that a joint
does not occur at the intersection of ceiling or roof joists. Elbows are
available in 90° and 45° configurations. Make allowances for elbows
as indicated in the appliance installation instructions.
Maintain a minimum 1” (25 mm) clearance to combustibles on the
vertical sections. Clearances for the horizontal runs are; 3” (76 mm)
on top, 1” (25 mm) on sides, and 1” (25 mm) at the bottom.
Install Vacuum Hose
• Refer to Figure 6 and remove the knockouts located where the strain
relief (#5) and snap bushing (#9) are to be installed, at the lower right
hand side.
• Install the snap bushing (#9) in the hole provided on the fireplace for
the vacuum hose (refer to Figure 6 ).
• Route the vacuum hose (#1), taking caution to not kink and/or damage
the hose (refer to Figure 6 ). Route the hose from the probe assembly
(#11) location to the appliance control compartment, through the snap
bushing previously installed. Ensure enough material is available at
either end to allow hook up. Ensure the hose is safety plated throughout
its run to prevent damage by framing nails and finish drywall screws.
Secure the vacuum hose (#1) to the probe (#11) with the hose clamp
(#8). Refer to Figure 7.
Route Wiring
NOTE: Electrical wiring must be performed by a qualified electrician.
• Install the strain relief (#5) in the hole provided on the fireplace for
the electrical wiring (refer to Figure 6 ).
• Remove the junction box cover (#22) from the termination by remov-
ing three screws (refer to Figure 8 ).

• Refer to Figure 10 to connect the three wires of the Romex cable to
the termination. Ensure the ground ring terminal is grounded beneath
a structural screw as shown. Attach the junction box cover (#22) to the
termination with the three screws previously removed.
• Route 14 gauge AWG grounded Romex wiring (not provided). Ensure
the wiring is safety plated to prevent damage by framing nails and fin-
ish drywall screws. Route the wire into the lower control compartment
and cut to length before installing the terminals. Install provided wiring
hardware (# 6,7) on the ends of the Romex wire.

Figure 13 Installing Power Vent Horizontal Termination
Installing Power Vent Termination
• Assemble vent run to exterior wall - If not
previously measured, locate the center of the
vent on the exterior wall. Prepare an opening
as described in the appliance installation
instructions. Assemble the vent system to a
point where the terminus of the last section
is within 8 inches of the outside wall surface
where the power vent is to be mounted (refer
to Figure 12 ).
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 thick-
nesses greater than that shown in Figure 12,
refer to the appliance Installation Instructions
for the additional venting components needed
(in addition to the termination and adapter) for
a particular range of wall thicknesses.
• Attach termination adapter - Attach the
adapter (adapter - SV4.5RCH - provided with the
power vent kit - #12) to the vent section telescop-
ing vent section, or elbow or appliance collar, as
shown in Figure 13 in the same manner as any
SV4.5 vent component.
• Install Firestop/Spacer at exterior wall -
Install SV4.5HF Firestop/Spacer (#13), provided
with the power vent kit, 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 13, and nail into place.
(The Firestop/Spacer may also be installed over
the opening at the interior side of the framing).
• Install the Power Vent termination (#10)
-For the last step, from outside the exterior
wall, slide the collars of the termination onto
the adapter (the outer inside the outer and the
inner outside 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 termination must not be recessed into the
exterior wall or siding by more that the 1-1/4”
(32 mm) as shown in Figure 12.
The Power Vent termination has been designed to perform in a wide range of weather conditions. Our terminations meet or exceed
industry standards.
When selecting the location of your termination, do not place the termination where water from eaves and adjoining roof lines may
create a heavy flow of cascading water onto the terminations. If the termination 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.
