Backflow
Preventer:
9007678005
(TK
‐
BF01)
The
Backflow
preventer
prevents
the
backflow
of
air
through
the
exhaust
vent.
This
helps
prevent
harmful
exhaust
gases
from
entering
the
home,
as
well
as
helping
to
prevent
the
unit
from
freezing
in
areas
where
cold
air
can
be
blown
or
drawn
into
the
exhaust
system.
Install
this
vent
damper
in
accordance
with
the
installation
instructions
and
any
applicable
codes.

Install
this

cover
is
fixed
to
the
bottom
of
the
water
heater,
which
hides
the
plumbing
and
improves
the
visual
aspects
of
the
whole
installation
for
the
water
heater.

Direct
‐
Vent
Concentric
Termination:
9007680005
(TK
‐
KPCT43)
Used
when
terminating
direct
‐
vent
(sealed
‐
combustion)
systems,
with
direct
‐
vent
models
that
require
a
3”
intake
and
a
4”
exhaust.
This
concentric
termination
provides
the
convenience
of
only
having
to
make
one
penetration
through
a
sidewall
instead
of
two
separate
penetrations
for
the
intake
and
exhaust
piping.
The
termination
includes
a
bird
screen,
restricting
small
animals,
pests,
and
foreign
objects
from
entering
into
the
vent
system.
This
sidewall
termination
is
available
in
three
different
sizes,
to
cover
all
ranges
of
wall
thicknesses.
