Vent Pipe Preparation - Bradford White EFR160T120 Series Installation & Operating Manual

It is acceptable to install a 90 degree elbow on IPEX concentric vent terminations use with this power direct vent water
heater (see Figure 23b). A short length of appropriate diameter vent pipe should be used to transition from the vent
terminal to the 90 degree elbow. Approved venting materials along with primers and cements are listed at the beginning
of this venting section. When the 90 degree elbow is used the equivalent length of the elbow and short length of vent
pipe must be factored into the total vent/air intake pipe determinations (see Tables 3 and 4 for appropriate vent
connector lengths).
