Install Firestop/Spacer at exterior wall | Lennox Hearth EN03-VDLPM

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 28, refer to Table 3 on page 18. This table lists the additional venting components needed (in addition to the termination and adapter) for a particular range of wall thicknesses.

M. Attach termination adapter - Attach the adapter (SV4.5RCH - provided with the termi- nation) to the vent section or telescoping vent section), elbow as shown in Figure 27 in the same manner as any SV4.5 vent component (refer to Step F).

N. Install Firestop/Spacer at exterior wall -

When using the square termination, install the SV4.5HF (Secure Vent) or SF4.5HF (Se- cure Flex) Firestop/Spacer over the open- ing at the exterior side of the framing (long side up) as shown in Figure 27, and fasten into place. Ensure 5" clearance is main- tained by framing above the vent run for MPLDV35/40/45 when center line of the run is lower than 48" (12119 mm) above

IMPORTANT: The vent termination is hot while in operation and for a period of time following use of the fireplace. To prevent contact with hot surfaces, we recommend the use of a Termination Guard. This can be purchased at your local dealer.

Figure 28

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.
