NOTES: * - First letter may be "A" or "T"

1.The INLET AIR of one pipe systems require the installation of a 90° elbow (to prevent dust and debris from falling straight into the furnace) and a 2 foot horizontal or vertical straight pipe section connected before or after the elbow.

2.DO NOT MIX PIPE DIAMETERS IN THE SAME LENGTH OF PIPE OUTSIDE THE FURNACE CABINET (Except adapters at the top of the furnace).

If different inlet and vent pipe sizes are used, the vent pipe must adhere to the maximum length limit shown in the table above (See Note 7 below for exception). The inlet pipe can be of a larger diameter, but never smaller than the vent pipe.

3.MAXIMUM PIPE LENGTHS MUST NOT BE EXCEEDED! THE LENGTH SHOWN IS NOT A COMBINED TOTAL, IT IS THE MAXIMUM LENGTH OF EACH (Vent or Inlet air pipes in two pipe systems).

4.One standard radius 90° elbow is equivalent to 12' of 4" pipe; one SHORT radius 90° elbow is equivalent to 10' of 3" pipe and one LONG radius elbow is equivalent to 6' of 3" pipe. One SHORT/LONG radius 90° elbow is equivalent to 7½' of 2½" pipe, & 5' of 2" pipe. Two 45° elbows equal one 90°elbow.

5.The termination tee or bend must be included in the total number of elbows. If the BAYVENT100 termination kit is used, the equivalent length of pipe is 5 feet. There is zero equivalent length for the BAYVENT200.

6.Pipe adapters are field supplied.

7.4" pipe may be reduced to 3" for termination with BAYAIR30AVENTA or BAYVENT200 without additional length restriction.
