Installation Procedure
A. Determine where the vent terminal will exit through the wall or roof.
1. The supplied vent kit includes a horizontal (through the wall) vent terminal, an elbow, a condensate trap, vent
connector clamps, and 6 1/2 ft. (2 m) of coaxial vent pipe. The 6 in. (15.3 cm) diameter venting system also is
supplied with an 8 in. (20.3 cm) to 6 in. (15.3 cm) reducer for the water heater vent connection. The coaxial vent
pipe includes both the flue exhaust (inside pipe) and combustion air intake (outside pipe). The coaxial vent pipe
may be cut on the unflared end (end without gasket) as required for the installation.
2. Determine if additional venting components are required for the venting installation. Refer to the venting
component table listed in the Direct Vent Installation section for available optional venting components.
3. Make sure the vent terminal location complies with the requirements described earlier and referenced in the latest
edition of the National Fuel Gas Code.
4. Measure the vertical and horizontal distance from the water heater vent connection to determine the number of
vent pipes needed.

B. Install Vent Terminal
Note: The supplied horizontal vent terminal may be used to vent through outside walls up to 24 in. (61 cm) thick.
1. Horizontal Vent Terminal (Through the Wall) (Supplied)
(a) Cut an opening of at least 8 1/2 inch (21.6 cm) in diameter. (See Figure 4).

(b) Slide the vent terminal through the wall opening until the rib closest to the intake air openings of the terminal is
even with the outside wall.
