Installation instructions
Horizontal venting systems only:
An optional stainless concentric vent/air intake
termination can be used to provide only one penetration
point through the exterior wall (see Fig. 8, 9 & 10). The
concentric vent/air intake kit can be ordered from your
local wholesaler. (Part# ESHCK). Note: Only tee
terminals are approved for use with the
concentric vent/air intake kit (see Table 3). Vent
piping and tee terminal used with kit must be
from the same vent pipe manufacturer. The
appliance can also be installed with separate air
intake and exhaust piping (see Fig. 15 ).

3.3.2 Venting Specifications
Install appliance as close to point of vent termination as
possible. The exhaust piping must vent directly to the
outside of the structure.
Horizontal sections of vent must pitch upward towards
termination ¼" for every foot of horizontal length, to
prevent the pooling of condensate, and be supported at
4 foot intervals with overhead hangers.
Exception: horizontal run between last elbow and
termination must pitch down to termination 1/4" per
foot. Note: For horizontal terminations, venting must
terminate once it penetrates to the outside of the
structure. There must be no sections of vent pipe
exposed to the outdoors other than the termination.
Note: Listed thimbles or collars are necessary where
venting passes through wall and ceiling partitions. If the
vent system passes through combustible areas where
the vent clearance requirements cannot be maintained,
it is permissible to chase straight sections of sea led 3
inch single wall vent through 4 inch (or greater) T ype-B
vent. The distance to combustibles using this chase
technique is 1 inch 1). Note: Type-B vent must never be
used as the actual exhaust vent system for the
appliance, as it is not gas tight and illegal for use with
this appliance. This will create a serious health hazard
and void the warranty.
