NOTES:
1. See Accessories section (page 20) for optional PVC Tee configurations and drainage options.
2. Drain lines must be trapped with a J-Trap or field supplied loop. Traps may be positioned inside or outside the cabinet. All drain lines must be routed externally
from the cabinet.
3. Inline drain is required only if “X” is greater than 6 feet.
4. Tubing needs to be cut to length and attached during unit installation.
5. Horizontal piping from inducer to flue pipe must be sloped 1/4” per foot to ensure drainage to PVC trap.
