Equivalent Vent Length (EVL)
The longer the run of pipe in your installation, the more restriction
there is in the system. Therefore, larger diameter pipe should be
used.
Use 4” pipe if you have more than
15 feet
of equivalent vent
length.
Horizontal pipe in the exhaust system shall not exceed a total
of 10’ of EVL.
Minimum of 6’ continuous run of vertical pipe is highly
recommended. 8’ is the optimal recommendation for most
efficient use.
To calculate EVL, use the following conversions:
90º elbow or “T”
= 5 equivalent feet
45º elbow
= 3 equivalent feet
Horizontal Pipe Run
= 1 equivalent foot per actual foot
Vertical Pipe Run
= 0.5 equivalent foot per actual foot
NOTE: At altitudes above 3,000 feet, we suggest the use of 4”
diameter vent at an EVL of 7 feet or more. If installing in a
corner and going out the side wall 4” diameter pipe should also
be used.
SOLSTICE INSTALLATION
A.
HORIZONTALLY THROUGH WALL
NOTE:
Follow L-Vent chimney manufacturer’s instructions and
minimum clearances. 3” minimum is standard, though depending
upon the pipe you purchase the minimum clearance may be more
or less than the 3” standard.
1.
Position stove, adhering to minimum clearances.
2.
Locate position of hole in wall; directly behind stove exhaust
vent (refer to figure 3).
3.
Always maintain 3” clearance from combustible materials.
4.
Install L-Vent wall thimble per L-Vent manufacturer’s
instructions.
5.
Attach enough piping to penetrate and extend at least 6”
beyond exterior walls. An 8-foot vertical pipe run is suggested
where possible to reduce the possibility of smoke spillage in
the event of a loss of negative pressure.
6.
Attach cap and seal outside wall thimbles with non-hardening
waterproof mastic.
7.
Termination should not be located so that hot exhaust gases
can ignite trees, shrubs, or grasses or be a hazard to children.
Exhaust gases can reach temperatures of 500ºF and cause
serious burns if touched.
8.
If installing in a corner and going out the side wall, be sure to
have a minimum of 6” straight pipe off the back of the stove
before installing elbow. Use 4” diameter pipe regardless of
EVL and minimum of 6’ of vertical pipe is highly recommended.
Locate terminations: 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; c) not
less than two feet from an adjacent building and not less than 7 feet
above a public walkway. Mobile home installations must use a spark
arrester.
