OPTIONAL ITEMS
1. TK-RE02 Temperature Remote Controller
The TK-RE02 Temperature
Remote Controller has two
functions. It allows the output
temperature from the T-K3-OS/SP
to be adjusted within the range of
99 °F to 167 °F, and it also works
as a diagnostic tool that will give a concise error code
whenever there is a problem with the unit. The
temperature options are 99°F, 100°F, 102°F, 104°F,
106°F, 108°F, 110°F, 111°F, 113°F, 115°F, 117°F,
122°F, 131°F, 140°F, 158°F, and 167°F. See the
trouble shooting section for information on possible
error codes.
2. TK-BF01 Backflow preventer (for T-K3-SP)
The TK-BF01 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 Takagi’s
installation instructions, and any applicable codes.
3. TK-TV04 Vent Cap (for T-K3-SP)
The TK-TV04 Vent Cap is
for outdoor installation with
the T-K3-SP water heater.
The cap is installed on the
top of the unit, instead of
connecting an exhaust vent
pipe. The cap will prevent
any debris that might be in
the environment from entering the unit and causing
damage or a fire hazard, as well as preventing rain or
other weather from entering the unit.
4. TK-PC01 Pipe cover
The TK-PC01 Pipe cover protects
the plumbing pipes to the T-K3-
OS/T-K3-SP from unexpected
adjustments. This pipe cover is
fixed to the bottom of the T-K3-
OS/T-K3-SP, which hides the
plumbing and improves the visual
aspects of the whole installation for
the water heater.
5. TK-RB01 Recess box (for T-K3-SP)
The TK-RB01 will allow for “clean”
installations. The T-K3-SP fits inside
the recess box, which hides and
protects the whole water heater and
plumbing. The TK-RB01 fit between
most wall studs.
6. TK-RB02 Recess box (for T-K3-OS)
The TK-RB02 will allow for
“clean” installations. The
T-K3-OS fits inside the
recess box, which hides
and protects the whole
water heater and
plumbing. The TK-RB02
fit between most wall
studs.
7. TK-KPWL4 and TK-KPWH4 T-Vent Wall thimble with Termination (for T-K3-SP)
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

thicknesses, there are 3 ranges of lengths available (refer to the T-Vent
brochure for details).

instructions and any applicable local co
des.
