Table 21 - Venting Components Required for Various Exterior Wall Thicknesses, when using Typical Termination Kits
NOTE: See Figure 29 for wall thickness ranges when using SV4.5HT-2 termination kit.
Horizontal Vent Figures/Tables
NOTE: Secure Vent
terminal may also be used.
NOTE: If the parameters of your vent run fall outside the parameters described herein, consider installing the Power Vent Kit.
NOTE: Two (2) 45° elbows may be used in place of one (1) 90° elbow. The same rise to run ratios, as shown in the
venting figures for 90° elbows, must be followed if 45° elbows are used.
NOTE: Rise per foot run ratios are acceptable all the way to level. For best results, maintain the horizontal/inclined
run in a straight (no dips), slightly elevated plane of approximately 1/4" per 1 ft (20 mm per 1 m).
NOTE: SV4.5VF (Secure Vent), SF4.5VF (Secure Flex) firestop/spacer must be used any time vent pipe passes
through a combustible floor or ceiling. SV4.5HF (Secure Vent), SF4.5HF (Secure Flex) firestop/spacer must be used
any time vent pipe passes through a combustible wall.
Do not join separate sections of concentric flexible vent together.

Install the U-shaped vent restrictor in any vent run with more than 6-1/2 ft of
vertical rise. See Page 20 for more information.
Small square termination (SV4.5HT-2) shown.
See Table 21 as an aid in venting component selection for a particular range of exterior wall
thicknesses.
15 ft total horizontal vent run requires a minimum of 10 ft total vertical vent.
Vertical firestop/spacer must be used anywhere vent pipe passes through a combustible floor or ceiling. Horizontal firestop/
u
spacer must be used anywhere vent pipe passes through a combustible wall.
Install the provided vent restrictor, if required.

A 90° elbow may NOT be attached directly to the appliance collar. A minimum 12" pipe section must be used between the fireplace

collar and a 90° elbow.
