Termination Options – Direct Vent Installation
The venting system of the Tx may be terminated using field supplied piping to construct a “Two-Pipe”
termination, see Figures 4-3a, 4-4a, 4-4d, 4-5a, 4-6a and 4-6d; alternatively the venting may be terminated using
a factory kit selected from Table 4-4.
Venting Options - Due to potential moisture loading (build-up) along the exterior wall,
sidewall venting may not be the preferred venting option (see Figures 4-4 and 4-6).
