APPENDIX A — BLOCK-OUT CONSTRUCTION (cont.)
Table C — STANDARD 88-IN. CABINET (Four-Pipe
42S Units)
* Not recommended for Siamese Back-to-Back Installation.
† Use 16-in. block-out length for risers up to 1

2
-in. in diameter. Use
17-in. block-out length for risers up to 2
1
/
2
-in. in diameter. Since the
cabinet is 17-in. wide, it may be necessary to cover the exposed
block-out if the cabinet is not centered.
** This block-out length is for risers up to 1
1
/
2
-in. in diameter. Add 1-in.
to the block-out length for risers up to 2
1
/
2
-in. in diameter. Both block-
out lengths are greater than the cabinet width. It will be necessary to
cover the exposed block-out at the side(s) of the cabinet.
†† This block-out length is for risers up to 1
1
/
2
-in. in diameter. Add 1-in.
to block-out length for risers up to 2
1

*** Use 17-in. block-out length for risers up to 1
1
/
2
-in. in diameter. Since
the cabinet is 17-in. wide, it may be necessary to cover the exposed
block-out if the cabinet is not centered. Use 18-in. block-out length for

-in. in diameter. It will be necessary to cover the
exposed block-out at the side(s) of the cabinet.
NOTES:
1. CLEAR HEIGHT is the dimension from the floor to ceiling (See
Fig. A of this appendix).
2. The above charts allow 1-in. tolerance in clear height to allow for
variance in floor-to-floor dimensions.
3. Consult factory for applications with 3-in. and 4-in. risers and insu-
lations exceeding
3
/
4
-inch.
4. See Figure B for 42SJ unit and piping arrangements.
