1. 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.
3. Pipe covers: 9007670005 (TK-PC01)
The pipe cover protects the plumbing pipes to
the water heater from unexpected adjustments.
This pipe 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.

2. Direct-Vent Conversion Kit: 9007667005
These terminations are used when venting out through the wall and
are compatible with the T-Vent pipe system. These terminations are
special stainless steel vents for gas appliances and are UL listed as
Category II, III and IV. There are two types of terminations: the Louver
termination and the Hood termination. For different wall thicknesses,
there are two ranges of lengths available (refer to the T-Vent brochure
for details). Install these vent terminations in accordance with their
)
installation instructions and any applicable local codes.
Used when terminating direct-vent (sealed-combustion) systems, with
direct-vent models that require a 3 in. (76 mm) intake and a 4 in. (102
mm) 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.
