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 runs shall not exceed 10’ of EVL. 
 
Recommended vertical runs to be a minimum of 8’. 
 
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. 
P2700 INSTALLATION 
A. 
HORIZONTALLY THROUGH WALL (refer to Figure 6) 
 
NOTE: Follow L-Vent chimney manufacturer’s instructions. 
 
1. 
Position stove, adhering to clearances shown in Figures 1 & 2. 
 
2. 
Locate position of hole in wall; directly behind stove exhaust 
vent (refer to figure 4). 
 
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. 
 
 
 
 
 
 
 
 
 
 
Locate terminations: a) not less then 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. Mobile home 
installations must use a spark arrester.
