Optional Items
1. Temperature Remote Controller (TM-RE30):
The Temperature Remote Controller has two functions. It allows the output
temperature from the 520H to be adjusted within the range of 38°C to 85°C
(100°F to 185°F), and it also works as a diagnostic tool that will give a con-
cise error code whenever there is a problem with the unit. The temperature
options are 38°C (100°F), 40.5°C (105°F), 43°C (110°F), 46°C (115°F), 49°C
(120°F), 52°C (125°F), 55°C (130°F), 57°C (135°F), 60°C (140°F), 63°C
(145°F), 65.5°C (150°F), 68°C (155°F), 71°C (160°F), 74°C (165°F), 77°C
(170°F), 79.5°C (175°F), 82°C (180°F) and 85°C (185°F). See the trouble
shooting section for information on possible error codes.
2. Pipe cover (TH-PC02):
The Pipe cover protects the plumbing pipes to the 520H models from unex-
pected adjustments. This pipe cover is fixed to the bottom of the water heat-
er, which hides the plumbing and improves the visual aspects of the whole
installation for the water heater.
3. Wall thimble with Termination (TK-KPWL4 and TK-KPWH4):
Louver Termination
TK-KPWL4
Hood Termination
TK-KPWH4
These terminations are used when venting out through the wall and are
compatible with the T-Vent pipe system.
These terminations are special stainless steel vents for gas appliances and
are UL listed as Category II, III and IV. There are two types of terminations:
the Louver termination and the Hood termination. For different wall thick-
nesses, there are two ranges of lengths available (refer to the venting bro-
chure for details).
Install these vent terminations in accordance with their installation instruc-
tions and any applicable local codes.
4. Neutralizer kit (TH-NT01):
The Neutralizer assembly neutralizes the condensate (acidic water) that
forms in the secondary heat exchanger of the 520H models. It connects to
the condensate drain port of the 520H models by using connectors included
with the neutralizer kit. Refer to pg. 16 for the details.
