Figure 31. Option CC6 Components
⚠ 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.
• Consider local snow depth conditions. The vent must be at least 6 inches (152 mm) above the
anticipated snow depth.
1 . Determine vent terminal location on outside wall:
a . Refer to
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 .
⚠ WARNING ⚠
Avoid positioning the vent terminal above a walkway as there may be a small amount of condensate
that drips from the end of the vent/combustion air terminal. In cold climates, the condensate may
form ice.
⚠ CAUTION ⚠
Products of combustion can cause discoloration of some building finishes and deterioration of
masonry materials. A clear silicone sealant normally used to protect concrete driveways may be
used to protect masonry materials from discoloration and deterioration. If discoloration is an
esthetic problem relocate the vent or install a vertical vent.
e . Refer to
to ensure that location complies with minimum clearance requirements .
