1. Temperature remote controller:
100209924 (TM-RE42)-Standard model
The temperature remote controllers have
three functions.
It allows the output
temperature from the water heater to
be adjusted. It also works as a diagnostic
tool and provides a concise error code
whenever there is a problem with the unit. See the
Troubleshooting Section (pp.53 to 56) for information
on possible error codes.
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.
It connects to the condensate drain port of the water heater with connectors included
with the neutralizer kit. (Refer to pp. 32 and 33.)
4. Sidewall vent terminator (Hood) and Wall thimble:
Terminator Hood
Wall Thimble
These are used when venting out through the wall. These terminations are special stainless steel
vents for gas appliances and are UL listed as Category II, III and IV. For different wall thicknesses, there
are two ranges of lengths available. (Refer to the NovaVent brochure for details.) Install these vent
terminations in accordance with their installation instructions and any applicable local codes.
5. 3" PVC concentric termination: 100112163 (TH-CVPVC33)
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.
6. 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. The recess box will fit between most wall studs.

2. Pipe cover:
100187904 (TH-PC04)
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.
