Big E Installation - Breckwell The Big E Owner's Manual

Equivalent Vent Length (EVL)
The longer the run of pipe in your installation, the more re-
strictions 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:
90 o elbow or "T"
45 elbow
o
Horizontal Pipe Run
Vertical Pipe Run
NOTE: At altitudes above 3,000 feet, we suggest the use of
4" diameter vent at an EVL of 7 feet or more.

BIG E INSTALLATION

A. HORIZONTALLY THROUGH WALL (refer to Figure 5)
NOTE: Follow L-Vent chimney manufacturer's instructions.
1. Positions stove, adhering to clearances shown in Figure
1.
2. Locate position of hole in wall; directly behind stove
exhaust vent (refer to fi gure 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 sug-
gested 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. Terminations should not be located so that hot exhaust
gases can ignite trees, shrubs, or grass or be a hazard to
children. Exhaust gases can reach temperatures of 500
and cause serious burns if touched.

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 horizon-
tally from, or 1 foot above any door, window or gravity air inlet into
any building; c) not less than 2 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.
