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.

DANGER

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 f. Refer to Figure 2-12: Run (do not connect) the COMBI drain from the COMBI as

described below:

1) Use Drain Kit, Cleveland Range Part No. C3416730. See Figure 2-12 A

2) Cut the 2” (50 mm) tubing to length.

3) Run 2” tubing of appropriate type to the drain outlet.

4) Leave minimum 1” clearance between end of the drain line and the top of floor drain.
