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.

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
