4. Install Free Air Vented Drain Lines

Furnishing and installing drain lines is the responsibility of the Owner/Installer.
a. The drain lines must be installed in compliance with the Basic Plumbing Code of the
Building Officials and Code Administrators International, Inc. (BOCA), and the Food
Service Sanitation Manual of the Food and Drug Administration (FDA) and any other
applicable national, state, or local codes and regulations.
b. Do not install the Combi directly over a drain. Steam rising up out of the drain will
adversely affect operation, hamper cooling air circulation, and damage electrical and
electronic components.
c. The total length of pipe and number of bend fittings required to reach the open drain
determines the pipe size used to extend the drain line to an open drain.
1) If the drain outlet extension requires 6 feet or less of pipe, and no more than two
elbows are required, 2 inch pipe and fittings are acceptable.
2) If drain outlet extension requires 6 to 12 feet of pipe, or requires three elbows, then 2½
inch pipe and fittings are required.
3) The drain line must have gravity flow from the Combi drain outlet to floor drain.
4) Do not install a trap in the drain line.
d. Free air venting requires minimum 1" clearance between the end of the drain line and the
top of the floor drain.
e. Do not connect the Combi drain directly to drains or to the plumbing of any other equipment
