7. Air Intake Inlet and Exhaust Gas Outlet Pipe Connections

DANGER

Improper venting of the water heater will result in

excessive levels of carbon monoxide, which can lead to

severe personal injury or death. This water heater must

be vented in accordance with the “Venting of Equipment”

section of the latest edition of the ANSI Z223.1 / NFPA

54 (Natural Fuel Gas Code) in the USA, or in Canada

refer to the “Venting Systems and Air Supply for

Appliances” section in the latest version of CAN/CGA

B149.1 (Natural Gas and Propane Installation Code), and

all applicable local building codes. Vent installation

should be performed only by a licensed professional.

WARNING

Do not operate flood damaged water heaters.
Install venting system according to the

required codes and material manufacturers

specifications.
Do not obstruct fresh air intakes or exhaust

outlets. Adequately support all vent system

piping.
Do not place vapor emitting products near

water heater or air intake.
Place working carbon monoxide detectors

outside each sleeping area.
Do not operate the water heater before

properly installing the exhaust outlet.
Visually inspect the vent system and

eliminate any possible area where

condensation could create a blockage of

intake or exhaust air.

Breathing concentrated levels of carbon

monoxide, even for a short period of time, will

cause brain damage and can even lead to

death.

Note:

This water heater falls into the Category IV appliance.

7.1 Quick Reference Installation Guide

1. Select the desired type of venting system: Two Pipe Vent

System (Direct) or Single Pipe Vent System (Power).

“7.3 Two Pipe Vent System (Direct Vent)” on page 20.

“7.4 Single Pipe Venting System (Power Vent)” on page

22.

2. Select the desired termination of the air intake inlet and

exhaust gas outlet pipe; outside wall or roof.

“7.3.3 Side Wall Air Intake Inlet and Exhaust Gas Outlet

Pipe Termination” on page 21.

“7.3.4 Roof Air Intake Inlet and Exhaust Gas Outlet Pipe

Termination” on page 22.

3. Determine the straight line distance and the number of

elbows required to route the air intake inlet and exhaust

gas outlet pipes to their termination point.

“7.6 Intake Air Inlet and Exhaust Gas Outlet Pipe

Diameter and Length” on page 24.

4. Determine the diameter of pipe required to properly bring

in intake air and vent exhaust gas.

“7.6 Intake Air Inlet and Exhaust Gas Outlet Pipe

Diameter and Length” on page 24.

5. Verify the location of the air intake inlet and exhaust gas

outlet terminations are within state and local codes.

“7.7 Venting Clearance Specifications” on page 25.

6. Select an approved material for the air intake inlet piping.

“7.8 Exhaust Gas Outlet Pipe Materials” on page 26.

7. Select an approved material for the exhaust gas outlet

piping. “7.9 Air Intake Inlet Pipe Vent Materials” on page

26.

7.2 Typical Single Unit Air Intake Inlet and

Exhaust Gas Outlet Pipe Installation

1. Select one of the two venting configurations: two pipes

(direct vent) configuration or with one pipe (power vent)

configuration.

2. Select the desired termination location and make sure

each pipe terminates within all local and state codes.

3. Select the desired material for the air intake inlet and

exhaust gas outlet pipes.

CAUTION

This water heater has a factory preset control to limit

the exhaust gas temperature to 149°F (65°C) when

the PVC is selected in the “Flue Type” programming

section. As a result, the water heater can be vented

with Schedule 40 PVC. If the incoming (or recirculation

return) water temperature does not exceed 150°F

(66°C), the exhaust gas temperature will not exceed

149°F (65°C).

WARNING

When the unit is set for CPVC (polypropylene pipe),

flue temperatures can reach 190°F (88°C). PVC pipe

will melt at temperatures above 149°F (65°C) and could

therefore result in a fire. Make sure the setting and the

type of material being used for the flue are compatible.

For this application use Schedule 80 CPVC or Approved

Polypropylene in the USA or Type BH Special Gas Vent

Class IIB (CPCV) or Class IC (Polypropylene) that

conforms to ULC-S636 in Canada.
