5. Vent Termination - Horizontal
The terminal must be located (U.S. – See Figure 25 on page 33):
• at least 3" and at most 12" out from the wall (see Figure 27 on page 35), following the vent manufacturer's
instructions
• at least 12" above finished grade or the normally expected snow accumulation level, whichever is higher
• at least 4 feet below or horizontally from, or 1 foot above, any doors or windows or gravity air inlet to a
building
• at least 3 feet above any forced air inlet located within 10 ft.
• at least 4 feet horizontally from electric meters, gas meters, regulators and relief equipment
• at least 7 feet above grade adjacent to walkways or similar traffic areas
The terminal must be located (Canada – See Figure 25 on page 33):
• at least 10 feet (3.3M) from any opening into a building
• at least 12" (.3M) above finished grade or the normally expected snow accumulation level, whichever is
higher
• at least 4 feet (1.2M) horizontally from electric meters, gas meters, regulators and relief equipment
• at least 7 feet (2.1M) above grade adjacent to walkways or similar traffic areas
Allow at least three feet (1M) vertical clearance over vent termination when terminating under an overhang.
Avoid corners or alcoves where snow or wind could have an effect. Exhaust may affect shrubbery and some
building materials. Keep shrubbery away from termination. To prevent staining or deterioration, sealing or
shielding exposed surfaces may be required.
Fire Hazard. Do not run the heater vent into a common vent with any other appliance. Do not run the Special Gas Vent into,
through, or within any active vent such as a factory built or masonry chimney.
