Sidewall termination – optional concentric vent
Description and usage
Lochinvar offers optional concentric combustion air and
vent pipe termination kits (Factory Kit #100140485 for 2"
diameter - Models 56 - 86, #100269005 for 3" diameter -
Models 56 - 200 and #100140484 for 4" diameter - Models
286 - 400). Both combustion air and vent pipes must attach
to the termination kit. The termination kits must terminate
outside the structure and must be installed as shown below
in FIG. 4-6.
The required combustion air and vent pipe materials are
listed in Table 3D, on page 20 of this manual.
