NOTES:

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.
