2.3 INSTALLATION
The unit must be installed with the prescribed 
clearances for service as shown in Figure 2.1. 
The minimum clearance dimensions, required by 
AERCO, are listed below. Local building codes 
may require more clearance and take 
precedence 
 
Minimum clearances required: 
Sides
24"
Front
18"
Rear
18"
Top
18"
 
All gas piping, water piping, and electrical 
conduit or cable must be arranged so that they 
do not interfere with the removal of any cover, or 
inhibit service or maintenance of the unit. 
 
 
WARNING!
KEEP UNIT AREA CLEAR AND FREE 
FROM COMBUSTIBLE MATERIALS AND 
FLAMMABLE VAPORS AND LIQUIDS
.
 
 
2.3.1. SETTING THE UNIT
Remove the unit from the wooden skid and 
place in position using a block and tackle or 
hoist attached to the lifting lugs, (see Fig. 2. 2). 
USE ONLY THE LIFTING LUGS TO MOVE 
THE UNIT. 
 
The KC-1000 is U/L approved for installation on 
combustible flooring. A 4” to 6" high house-
keeping concrete pad is recommended and 
allows for sufficient drainage of the condensate. 
 
It is suggested that units be secured using the 
holes provided in the frame base. Piping must 
not be used to secure the unit in place. See 
drawing AP-A-568 in Appendix F for the base 
frame dimensions. 
 
In multiple unit installations, it is important to 
plan the position of each unit. Sufficient space 
for piping connections and future maintenance 
requirements must be given. All piping must 
include ample provision for expansion. 
 
If installing a Combination Control (CCP) 
system, it is important to identify and place the 
Combination Mode units in the proper physical 
location.
