Note: this is a excellent method to address the minimum of 3 inches of clearance needed on each side.
This could give you the space needed for the cabinet to fit.

Exposing Pipes

If you want the (feed) or (return) pipes exposed.
 

 We will need to know what side , how high , and center point to make the cut. 

Step 1: measure height ....

a.)  Standard cut on valve side is E=(9" High x 4" Wide). Fill in the 'E' dimension on your worksheet.
 
b.)  Standard cut on pipe side is e=(6" High x 4" Wide). Fill in the 'e' dimension on your worksheet.

Step 2: measure center....

* HC  is an important dimension to determine where to make the cut on the side of the cabinet.  Measure from the back quarter-round molding or toe board to the center of the pipe.  This is your HC dimension!

Important: Always measure from the top of the radiator when determining (Length or L dimension) when you are going to have pipes exposed on both sides.  This will insure that  you do not miss the extra length needed for bleeder valves or steam vents.
