ent and Air-Intake Pipe Length Determination
Use Table 3-4 to determine the maximum pipe length that can be used. The table calculates sweep, 90º elbows, and 45º elbows at
5 equivalent feet [1.52 m] each. Note: models Ti150-200 have limitations when operating with Propane Gas (LP).
Example : A Ti200 can be installed with 105 equivalent feet [32 m] of air-intake piping and 105 equivalent feet [32 m] of vent
piping when operating with Natural Gas. When operating with Propane Gas (LP), the maximum vent length in equivalent feet is
limited to 50’ (3” pipe).
The length of one vent pipe (intake or exhaust) may not exceed the length of the other vent pipe by
more than 20 equivalent feet (6.1 m).

Termination Options
The venting system of the Trinity Ti may be terminated using field supplied piping to construct a “Two-Pipe” termination, see
Figures 3-3, 3-4a, 3-6, 3-9, 3-10 and 3-11. Alternatively, the venting may be terminated used a factory kit, either “Concentric”
(see Figures 3-2, 3-4b, 3-5 and 3-7) or “Low Profile” (see Figure 3-8). The Concentric Vent Termination Kit can be either Roof
or Sidewall terminated, while the Low Profile Termination Kit may only be Sidewall terminated. See Table 3-5 for details on the
optional termination kits.
Venting Options - Due to potential moisture loading (build-up) along the exterior wall, sidewall
venting may not be the preferred venting option. See Figs 3-2(b) and 3-3(b).
Optional Termination Kits
Kits certified with the Trinity Ti are listed in Table 3-5 and available from IPEX and/or NTI. For more information on System 636
