INSTALLATION
2-2
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
24"
Rear
36"
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
.
CAUTION!
While packaged on the shipping skid the
boiler must be moved by pallet jack or
forklift from the rear only.
2.3.1. SETTING THE UNIT
Lifting lugs are provided for moving the unit
when it has been removed from the shipping
skid (See Fig. 2.2). Remove the corrugated box
and wrapping material from the unit. Remove
the rear top panel from the unit to provide
access to the lifting lugs. Remove the four- (4)
lag screws securing the boiler to the shipping
skid. Lift the unit off the shipping skid and
position it on to the four-inch high mounting pad
(required) in the desired location. If anchoring
the unit, see the dimensional drawing in
appendix F for their location. USE ONLY THE
LIFTING LUGS TO MOVE THE UNIT.
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. If these boilers are not properly located,
it will be necessary to reprogram them.

2.3.2 SUPPLY AND RETURN PIPING
The Benchmark 2.0 utilizes 4" 150# flanges for
the water system supply and return piping
connections. See appendix F for dimensional
data. The physical location of the supply and
return piping connections is on the rear of the
unit (See Fig 2.3 For Details).
