Combustible Air Supplied by
Mechanical fan or Make up air device.
The T-KJR water heater is equipped with a
combustible air sensor that will shut off the unit
when inadequate combustible air supply to unit
is detected.
If a mechanical fan or make up air device is
used to supply air to the water heater or utility
room, the installer should make sure it does
not create drafts which could cause nuisance
shutdowns. If a blower is necessary to provide
adequate combustion air to the water heater, a
switch or equivalent device must be wired
(interlocked) with the water heater control
circuit or other proper devices to prevent the
water heater from firing unless the blower is
operating.
Direct intake vent system
This T-KJR water heater may be converted to
a direct vent (sealed combustion) appliance by
installing an adapter (part No TK-TV09) which
will bring all required combustible air from
outside the building. The T-KJR must be
installed in a location where the proper amount
of combustible air will be available to it at all
times without obstructions. If used as a direct
vent appliance, the T-KJR requires a 3”
combustible air supply pipe. The intake pipe
must be sealed airtight with aluminum tape and
can be made of ABS, galvanized steel,
corrugated aluminum, corrugated stainless
steel or Category III stainless steel.
T-KJr is not necessary to change the dip
switch setting.
VENTING INSTRUCTIONS
General
WARNING: Improper venting of this appliance
can result in excessive levels of carbon
monoxide which can result in severe personal
injury or death.
This water heater must be vented in
accordance with the section “Venting of
Equipment" of the latest edition of the Natural
Fuel Gas Code, ANSI Z223.1 and all
applicable local building codes. In Canada,
follow section 7 of the CAN/CSA B149.1
Natural Gas and Propane Installation Code.
Exhaust Vent
This is a Category III appliance and must be
vented accordingly. The vent system must be
sealed air tight. All seams and joints must be
sealed with high heat resistant silicone sealant
or UL listed aluminum adhesive tape having a
minimum temperature rating of 350ºF. For best
results, a vent system should be as short and
straight as possible.
This unit requires 4”, Category III approved,
single wall stainless steel vent pipe or any
other Category III approved, non-combustible,
corrosion-resistant material. The following are
UL listed manufacturers: ProTech Systems Inc.
(FasNSeal), Flex-L Inc., Z-Flex Inc. (Z-Vent III)
and Heat-Fab Inc. (Saf-T Vent). Follow the
vent pipe manufacturer’s instructions when
installing the vent pipe. Do not common vent
this appliance with any other vented appliance.
The maximum length of exhaust vent piping
must not exceed 35 ft. deducting 5 ft. for each
elbow used in the venting system. Do not use
more than 3 elbows.

When installing the vent system, all applicable
national and local codes must be followed. If
you install thimbles, fire stops or other
protective devices and they penetrate any
combustible or noncombustible construction,
be sure to follow all applicable national and
local codes.
When the horizontal vent run exceeds 5 ft., the
following criteria must be observed:
Support the vent run at 3 ft intervals with
overhead hangers.
Slope the vent run downwards toward the
vent terminal at a rate of ¼” per foot.
