3. Neutralizer kit: 100112159
The neutralizer assembly neutralizes the condensate (acidic water) that forms in the secondary heat
exchanger of the water heater.
It connects to the condensate drain port of the water heater by using connectors included with the
neutralizer kit. (Refer to pages 34 and 35.)
1. Temperature remote controller:
100209924 (TM-RE42)
The temperature remote controllers have
three functions. It allows the output
temperature from the water heater
to be adjusted and it also works as a
diagnostic tool and it provides a concise
error code whenever there is a problem with the unit.
See the Troubleshooting Section (pages 53 to 55) for
information on possible error codes.
4. 3" PVC concentric termination: 100112163
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.
2. Pipe cover:
100112718 (TH-PC03) for 240HX3/340HX3/540HX3
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.
7. 4" PVC Adapter: 100113129
6. Non-return valve: 100113130
It is a must-have item for common
venting system. It prevents the
escape of combustion gas through
non-operating appliances. (Refer to
pages 28 and 29.)
This adapter transitions from the
Non-return valve outlet to 4"
schedule 40 PVC pipe.
5. Recess box:
It allows for “clean” installations. The water heater fits inside the recess box, which hides and protects the
whole water heater and plumbing.
