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).
