3. Neutralizer kit: 100112159 (TH-NT01)
The neutralizer assembly neutralizes the condensate (acidic water) that forms in the
secondary heat exchanger of the water heater. (Refer to pp. 35 and 36.)
The temperature remote controller has
the following features:
•
Adjusts set water temperature
•
Controls the pump operation
•
Works as a diagnostic tool
•
provides a concise error code whenever there is a problem
with the unit.

5. 3" PVC
concentric termination: 100112163 (TH-CVPVC33)

systems, with Indoor models that require a 3 in (76 mm) intake
and a 3 in (76 mm) exhaust.
2. Pipe cover:
100112718 (TH-PC03)
4. Sidewall vent terminator (Hood) and Wall thimble:

6. Non-return valve for common venting : 100113130
It is a must-have item for common
venting system. It prevents
the escape of combustion gas
through non-operating appliances.
(Refer to pp. 26 and 27.)
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.
(Refer to p.19.)
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.
Refer to pp. 50 to 59 for more information.
See the Troubleshooting Section (pp. 64 to 69) for information
on possible error codes.
7. PVC Adapter: 100113129
This adapter transitions
from the Non-return valve
outlet to 4" schedule 40
PVC pipe.
