Note: The venting distance shown in the chart above is the combined maximum distance for the intake and exhaust pipe and elbows. The intake and exhaust vent terminals may be in different locations (i.e., different walls or one wall, one roof) provided the intake equivalent venting distance does not exceed the exhaust by more than 30 feet (9 m).

Determining required vent length:

1.Determine the total length of straight vent pipe (in feet) required for both the intake and the exhaust.

2.Add 5 feet (1.5 m) of venting for every 90° elbow.

3.Add 2 ½ feet (.7 m) of venting for every 45° elbow.

4.Total vent length cannot exceed “Max Vent Length” in Table 3.

5.Air intake cannot exceed exhaust by more than 30 feet (9 m) in any venting situation.

Example of Total Direct Vent Length for EF100T199:

A 3 inch (7.6 cm) venting system has a total of six 90-degree elbows and a total straight pipe length of 65 feet (19.5 m) (includes both intake and exhaust pipe).

Equivalent vent length for elbows: 6 x 5 feet (1.5 m) = 30 feet (9 m).

Total equivalent vent distance = 65 feet (19.5 m) + 30 feet (9 m) = 95 feet (28.5 m) total equivalent vent length. This is below the maximum allowed distance of 100 feet (30 m) for this model using 3 inch (7.6 cm) vent.

NOTICE

Do not include the 3 inch (7.6 cm) condensate elbow or vent terminals in determining maximum vent length.

POWER VENT INSTALLATION

Power venting is where the indoor air is used and the exhaust is vented to the outside. Venting may be run horizontally through an outside wall or vertically through a roof through using either 3 inch (7.6 cm) or 4 inch (10.2 cm) diameter PVC, ABS or CPVC. This water heater is supplied with a screened intake elbow and exhaust coupling referred to as the air intake terminal and the exhaust vent terminal

Power Vent Terminal Location:

Refer to the “Direct Vent Terminal Location” section previously mentioned to determine the proper exhaust vent location. Plan the vent system layout so that proper clearances are maintained from plumbing and wiring.

Vent pipes serving power vented appliances are classified by building codes as “vent connectors”. Required clearances from combustible materials must be provided in accordance with information in this manual under LOCATION OF WATER HEATER, and CLEARANCES, and with National Fuel Gas Code and local codes.
