General Venting
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 4-4(a), 4-5(a), 4-5(d), 4-6(a), 4-7(a) and 4-7(d); alternatively the venting may be
terminated using a factory kit selected from Table 4-5.
Sidewall Termination – Due to potential moisture loading (build-up) along the exterior
wall, sidewall venting may not be the preferred venting option. Refer to Figures 4-5 and
4-7 for roof top venting options.
The vent for this appliance shall not terminate over public walkways; or near soffit vents
or crawl space vents or other area where condensate of vapor could create a nuisance or
hazard or cause property damage; or where condensate or vapor could cause damage or
could be detrimental to the operation of regulators, relief valves, or other equipment.
Extra precaution must be taken to adequately support the weight of the Vent/Air-inlet
piping in applications using roof-top terminations. Failure to follow these instructions
may result in venting or boiler component failure resulting in flue gas spillage leading to
property damage, serious injury or death.
It is acceptable to terminate the exhaust vent and air-inlet on adjacent or opposite walls to
each other {or one on the roof with one on the sidewall – see Figure 4-5(b)} provided the
required installation clearances are observed.
