2. Direct-vent conversion kit: 9007667005
(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.
4. Recess box: 9007674005 (TK-RB02)
The recess box will allow for “clean”
installations. The water heater
fits inside the recess box, which
hides and protects the whole water
heater and plumbing. The recess
box will fit in-between most wall
studs.
1. 4” Backflow preventer and F-F adaptor:
9007996005
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.
5. Sidewall vent terminator (Hood) and Wall thimble:
Used when terminating direct-vent (sealed combustion) systems, with indoor
models that require a 3 in. intake and a 4 in. 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. For different wall thicknesses,there are two ranges of lengths
available. (Refer to the NovaVent brochure for details.)
