2. Direct-vent conversion kit: 100112184
(TK-TV10)
This kit can be used
to convert the water
heater from a single
vent system to a
direct-vent (double vent) (or sealed combustion)
system with a 3 in. (76 mm) intake. Install this
conversion kit in accordance with the installation
instructions and any applicable codes.
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.

1. 4” Backflow preventer and F-F adaptor:
100112416
There are two functions available for this
adaptor, which can be connected with the
water heater and NovaVent venting line
and 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 adaptor in accordance with the installation
instructions that are packaged with the adaptor and
any applicable codes.

They are used when venting out through the wall. These terminations are special stainless steel vents
for gas appliances and are UL listed as Category II, III and IV. For different wall thicknesses, there are two
ranges of lengths available. (Refer to the NovaVent brochure for details.) Install these vent terminations
in accordance with their installation instructions and any applicable local codes.
Wall Thimble
Terminator Hood
Used when terminating direct-vent (sealed combustion) systems, with
indoor 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 two
different sizes, to cover a wide range of wall thicknesses.
(Refer to the venting manufacturer's specifications for details.)

It allows for “clean” installations. The water heater fits inside the
