APPENDIX A — BLOCK-OUT CONSTRUCTION
This section provides rough guidelines for the block-out slot
size for 42S units with risers included. Therefore, the floor
block-out slot dimensions listed in this document should be
considered estimates. The engineer for the project is ultimate-
ly responsible for the actual dimensions and meeting local
code requirements.
To select using the following Tables A-D, locate the appropri-
ate unit size in the cabinet charts (dimensions are given in
inches). Then, follow the row across to locate the clear height
(If the clear height exceeds 96-in. use the 96-in. block-out
size). Under type of installation, read the block-out size. If the
clear height is lower than listed or is not recommended (NR)
in the standard 88-in. cabinet chart, use the short 79-in. cabi-
net chart. If the clear height is lower than listed or is not rec-
ommended (NR) in the short 79-in. cabinet chart, please con-
tact the factory.
For examples of clearance height, unit placement, and riser
length see Fig. A. For possible piping arrangements of the
42SJ unit see Fig. B.
Table A — STANDARD 88-IN. CABINET, TWO-PIPE
UNITS
* Not recommended for Siamese Back-to-Back Installation.
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.
Table B — SHORT 79-IN. CABINET, TWO-PIPE
UNITS
* Not recommended for Siamese Back-to-Back Installation.
NOTES:

2. The above charts allow 1-in. tolerance in clear height to allow for

lations exceeding
