Installation / Operation Instruction Manual

Venting continued-

Figure 9a

Through the Roof Venting (Vertical Venting Standard Terminals):

Cut the necessary holes through the roof and ceiling and install the vent connector as

shown in Figure 6. Make sure that the installation meets the local codes and/or The

National Fuel Gas Code ANSI Z223.1 (Latest Edition) or CGA/CAN B149 Installation

Code (latest edition).

It is acceptable to install a 90° elbow on IPEX concentric vent terminations use with this

power direct vent water heater (see Figure 9b). A short length of appropriate diameter

vent pipe should be used to transition from the vent terminal to the 90° elbow. Approved

venting materials along with primers and cements are listed at the beginning of this

venting section. When the 90° 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 1 and 2 for appropriate vent connector lengths).
