WARNING

The EF100T250 and EF100T300 models are not approved for 2 inch diameter vent pipe. Venting with 2 inch pipe on these models may result in damage to the water heater or cause an unsafe condition. DO NOT use 2 inch Vent or Air Intake Pipe on EF100T250/300 models.

Determining required vent length:

1.Determine the total length of straight vent pipe (in feet) required.

2.Add 5 feet of venting for every 90° elbow.

3.Add 2 ½ feet of venting for every 45° elbow.

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

Example of Total Vent Length for EF100T199 with a power vented installation:

A 3” venting system has a total of six 90-degree elbows and a total straight pipe length of 55 feet. Equivalent vent length for elbows: 6 x 5 feet = 30 feet.

Total equivalent vent distance = 55 feet + 30 feet = 85 feet total equivalent vent length. This is below the maximum allowed distance of 100 feet for this model using 3” vent.

NOTICE

Do not include the 3” condensate elbow or vent terminals in determining maximum vent length.
