Termination Options – Direct Vent Installation
The venting system of the VM110 and VM110P 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 4-4.
Venting Options - Due to potential moisture loading (build-up) along the exterior wall,
sidewall venting may not be the preferred venting option (see Figures 4-5 and 4-7).
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.
