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.
5. 3" ULC S636 PVC Concentric Termination: TH-CVPVC33
Used when terminating direct-vent (sealed-combustion)
systems, with direct-vent models that require a 76 mm (3
in.) intake and a 76 mm (3 in.) exhaust. 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.
NOTE: Concentric (single penetration) terminations are
only permitted for sidewall (horizontal) terminations.
Roof (vertical) terminations must use two separate
penetrations.
Installation
Installation Manual
The temperature remote controller has two
functions. It allows the output temperature from
the water heater to be adjusted within the range
of 38 °C to 85 °C, and it also works as a diagnostic
tool that will give a concise error code whenever
there is a problem with the unit. The temperature
options are 38 °C (100 °F), 40 °C (105 °F), 43 °C
(110 °F), 45 °C (115 °F), 50 °C (120 °F), 52 °C (125
°F), 55 °C (130 °F), 57 °C (135 °F), 60 °C (140 °F), 63
°C (145 °F), 65 °C (150 °F), 68 °C (155 °F), 70 °C (160
°F), 75 °C (165 °F), 80 °C (175 °F) and 85 °C (185 °F).
See the troubleshooting section for information
on possible error codes.
1. Temperature remote controller:
TM-RE40
2. Backflow Preventer: TK-BF01
The backflow preventer prevents the backflow
of air through the exhaust vent. This helps
prevent harmful exhaust gases from entering
the home, as well as helping to prevent the
unit from freezing in areas where cold air can
be blown or drawn into the exhaust system.
Install this vent damper in accordance with
the installation instructions and any applicable
codes.
3. Pipe covers: TH-PC03 4. Neutralizer kit: 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
by using connectors included
with the neutralizer kit. Refer
to p. 24 for the details.
