INSTALLATION INSTRUCTIONS
Locate the fireplace as per the instructions supplied under the fireplace. Make the following modifications to add the components used with the Power Vent Kits. This kit can only be used in conjunction with “Direct Vent” series electronic versions of Lennox Fireplaces. This installation must conform with local codes or, in the absence of local codes, with the Natural Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane Installation Code, CSA B149.1.
CAUTION: The LPVK-110 Power Vent Kit cannot be used with Millivolt appliances. Use the LPVK-110 only with the Electronically con­trolled fireplaces listed for its use as shown in this document.

Modify fireplace for acceptance of the power vent kit. Refer to Table 1 and install the appropriate adapter kit. Follow the instructions provided with the kit to successfully prepare the fireplace for use with power venting. If no kit is listed, the fireplace will not require modification. Refer to the fireplace installation instructions for details and information detailing its compatibility with power venting. If its is not compatible, do not power-vent the fireplace.
VENTING THE FIREPLACE Venting Configurations
Maximum vent is 110 feet, plus six 90-degree elbows or twelve 45­degree elbows. Minimum horizontal vent length is 8 feet, maximum vertical rise above the fireplace is 66 feet. The vent can be installed with any combination or rise and run between appliance and termina­tion, including up to 3 feet below the unit (see Figure 2 ). Ensure vent pipe is properly supported.

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 ).
Figure 4
CAUTION: The probe assembly must be installed directly to the ap­pliance 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 com­ponents 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.

• Install the strain relief (#5) on the termination as shown in Figure 9.
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 sec­tions 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.
• 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 fin­ish 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.

Strain Relief (5)
Snap Bushing (9)
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 remov­ing three screws (refer to Figure 8 ).

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 thick­nesses 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 telescop­ing vent section, or elbow or appliance collar, as shown in Figure 13 in the same manner as any SV4.5 vent component.
Figure 12
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.
