Direct vent termination clearances (key limits)
What is going on
Clearances come from Figure 32 and its footnotes. The figure text is jumbled in the source, so verify every value against the full figure before installing. The points below are the ones that are clearly stated.
Check in this order
- Keep the vent terminal at least 7 ft (2.1 m) above a paved sidewalk or paved driveway on public property.
- Do not terminate under a veranda, porch, deck or balcony unless it is fully open on a minimum of two sides beneath the floor. The manual recommends avoiding this location if possible.
- Keep the minimum clearance above grade, veranda, porch, deck or balcony as shown in Figure 32 for the appliance input rating.
- Keep clearances to windows, doors, soffits and corners as shown in Figure 32.
- For clearances not listed in ANSI Z223.1/NFPA 54 or CSA B149.1, follow local codes and the gas supplier's requirements.
Applies to: Direct vent terminations, U.S. and Canadian installations
