Breckwell P23FS - Freestanding Installations

Equivalent Vent Length (EVL)
The longer the run of pipe in your installation {both with inserts
and freestandings), the more restriction there is In the system.
Therefore, larger diameter pipe should be used. Here is how
you determine whether 3‘ or 4" should be used in your
installation.
If you have over 15 feet of equivalent vent length, we
recommend the use of 4" pipe.
To calculate EVL, use the following conversions:
90° elbow or “T" =5 equivalent feet
45° elbow = 3 equivalent feet
Horizontal Pipe Run = 1 equivalent foot per actual foot
Vertical Pipe Run = 0.5 equivalent feet per actual foot
NOTE: At altitudes above 3,000 feet, we suggest the use of
4“ diameter vent at an EVL of 7 feet.
2.41 FREESTANDING INSTALLATIONS
A. Assembling PEDESTAL SET
Follow instructions inside Breckwell P23 Pedestal Set (A-P23-P).
(see figure 3)
B. HORIZONTALLY THROUGH WALL (see figure 4)
NOTE: Follow L-Vent Chimney manufacturer’s instructions.
1. Position stove, adhering to clearances shown in section 2.0.
2. Locate position of hole in wall, directly behind stove’s
exhaust vent (see figure 2).
3. Install L-Vent wall thimble per L-Vent manufacturer’s
instructions.
4 Attach enough pipe to penetrate and extend at least 6”
beyond exterior waits. An eight foot vertical pipe run is
suggested where possible to reduce the possibility of
smoke leakage in the event of a power failure.
5. Attach L-vent adapter to rear exhaust. Seal with metallic
tape.
6 Attach cap and seal outside wall thimbles with non¬
hardening waterproof mastic.
7. Termination should not be located such that hot exhaust
gases can ignite trees, shrubs, grasses, or be a hazard to
children. Exhaust gases can reach temperatures of 500°F
and cause serious burns if touched. Locate termination: a)
not less than 3 feet above any forced air inlet located within
10 feet; b) not less than 4 feet below or horizontally from,
or one foot above any door, window or gravity air inlet into
any building; c) not less than two feet from an adjacent
building and not less than 7 feet above grade when located
adjacent to a public walkway.
