Vertical & Horizontal Termination

1.Determine the pipe diameters required for the installation from Table 10 and Table 11 and Figure 46.

2.Determine the best location for the termination kit. See

Figure45 for vertical termination or Figure 45 and

Figure 49 for horizontal termination. Roof termination is preferred since it is less susceptible to damage, has re-

duced intake contaminants and less visible vent vapor. For

side wall termination, consideration should be given to: 1)

possible damage from the vapors to plants/shrubs, other equipment and building materials, 2) possible damage to the terminal from foreign objects, 3) wind effects that may

cause recirculation of flue products, debris or light snow and 4) visible vent vapor.

3.Cut one 5" diameter hole through the structure for the

NAHA001CV Kit or one 4" diameter hole for the

NAHA002CV Kit.

4.Dimension D may be lengthened to 60" max. or shortened by cutting the pipes to 12" min. Dimension A will change ac-

cording to D dimension. (See Figure 46)

1.Do not include the field supplied 45 ° elbow in the total elbow count,

2.If more than four elbows are required, reduce the length of both the inlet and the exhaust pipes five feet for each

additional elbow used.

3, Elbows are DWV long radius type for 2" and 3" vents,

NOTE: Feet of pipe is whichever pipe run is the longest, either inlet or outlet side,
