Breckwell Breckwell Hearth Products LUXURY SERIES Heating System User Manual


 
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.
