Installation instructions
Horizontal venting systems only:
An optional stainless concentric vent/air intake termina-
tion can be used to provide only one penetration point
through the exterior wall (see Fig. 8, 9 & 10). The con-
centric vent/air intake kit can be ordered from your local
wholesaler. (Part# ESHCK). Note: Vent piping and
terminal used with concentric vent/air intake 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.
For specific questions concerning vent material, speci-
fications, usage or installation, please contact the vent
manufacturer directly.
