Horizontal Vent Terminal (Option CC6) Installation
• Field-supplied components required for installation of the horizontal vent kit are as follows:
• Vent and combustion air piping—6- and 8-inch single-wall galvanized pipe
• 22.5-degree elbow (if available)
• Flashing
• Sheet metal screws, tape, and sealant, as required
• Factory-supplied components for installation of the vertical vent kit are listed in Table 16 and shown in Figure 15.

Install the horizontal vent kit as follows:
⚠ DANGER ⚠
• To prevent combustion products from entering the occupied space, all vent terminals must be
positioned or located away from fresh air intakes, doors, and windows. Failure to comply could
result in severe personal injury or death and/or property damage.
• In climates with below freezing temperatures, condensate may form icicles on the vent terminal.
Locate the terminal where falling icicles do not present a hazard.
1. Determine vent/combustion air terminal location on outside wall:
a. Refer to Table 8 and Table 9 to ensure that location complies with vent length requirements.
b. For most applications, ensure that vent terminal is level with heater mounting height.
c. Allow downward pitch of 1/4-inch per foot (6 mm per 305 mm) for condensate drain.
NOTE: Local codes supersede all provisions in these instructions and in National Fuel Gas Code
Z223.1.
d. Ensure that distance of vent terminal from adjacent public walkways and buildings and window and building
openings complies with local codes. Absent any local codes, distance must comply with National Fuel Gas
Code Z223.1.
