INSTALLATION
Equivalent Vent Length (EVL)
The longer the run of pipe in your installation (both with insert and freestanding), 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 feet of EVL.
∙Recommended vertical runs to be a minimum of 8 feet.
∙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.
FREESTANDING INSTALLATION
A. HORIZONTALLY THROUGH WALL | (refer to Figure 8) |
NOTE: Follow
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 5).
3.Always maintain 3” clearance from combustible materials.
4.Install
5.Attach enough piping to penetrate and extend at least 6” beyond exterior walls. An
6.Attach cap and seal outside wall thimbles with
Termination should not be located so that hot exhaust gases can
ignite trees, shrubs, or grasses or be a hazard to children. ExhaustFIGURE 8 gases can reach temperatures of 500ºF 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 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.
