Vent Termination
A sidewall vent terminator must be used when
the water heater is vented through a sidewall.
Takagi recommends the use of its part No.TK-
TV01 or the TK-TV05 with the TK-TV09 when
using the direct vent option. The vent
terminator provides a means of installing vent
pipe through the building wall and must be
located in accordance with ANSI Z223.1/NFPA
54, or in Canada with CAN/CSA-B149.1 and
local applicable codes.
Locate the vent terminator so that it cannot be
blocked by snow. Most codes require that the
terminator be at least 12 inches above grade,
but the installer may determine if it should be
higher depending on the job site condition and
applicable codes.
WARNING: Improper installation can cause
nausea or asphyxiation, severe injury or death
from carbon monoxide and flue gases
poisoning. Improper installation will void
product warranty. For high altitude installation
above 4,500 feet, contact Takagi on how to
handle this situation.
General rules for venting the T-KJR water
heater are:
1. Place the water heater as close as possible
to the vent terminator;
2. The vent collar of the water heater must be
fastened directly to an unobstructed vent
pipe.
3. Do not weld the vent pipe to the water
heater collar.
4. The weight of the vent stack must not rest
on the water heater.
5. The vent must be easily removable from
the top of the water heater for normal
service and inspection of the unit.
6. The water heater vent must not be
connected to any other gas appliance or
vent stack.
7. Avoid locating the water heater vent
terminator near any air intake devices or
air-conditioning units. These fans can pick
up the exhaust flue products from the water
heater and return them to the building. This
can create a health hazard.
8. Avoid using an oversized vent pipe or using
extremely long runs of the pipe.
