CENTURION Installation, Operation & Maintenance Manual
SECTION 2: INSTALLATION
W A R N I N G !
Keep unit area clear and free from all combustible materials and flammable vapors or liquids.
FOR MASSACHUSETTS ONLY:
For Massachusetts installations, the unit must be installed by a plumber or gas-fitter licensed
within the Commonwealth of Massachusetts. In addition, the installation must comply with all
requirements specified in Section 1.4, above.
2.3.2 Setting The Unit
If anchoring the unit, refer to Figure 2-2 for anchor locations.
•
All holes are flush with the bottom surface of the frame.
•
All dimensions shown are in inches [millimeters]
Figure 2-2: Anchor Bolt Locations
2.3.3 Housekeeping Pad Requirements
To ensure proper condensate drainage, the unit must be installed on a level concrete
“housekeeping” pad. The unit must be positioned on the pad such that the condensate
assembly is
not
located over the pad, as shown below.
The minimum thickness of the concrete pad depends on two factors:
•
Which Centurion
model you’re installing
•
Whether the unit will connect to a Condensate Neutralizer tank.
The minimum pad thickness for installations
without
a Condensate Neutralizer tank is
4 to 8
inches
(10.2 to 20.3 cm)
If you are using the Condensate Neutralizer Tank (P/N
89030C
), you must ensure enough
height for the condensate to drain into the condensate trap, then into the neutralizer tank, and
then to the drain. This may require that a pit be dug for the Neutralizer Tank. For more
information on the Condensate Neutralizer Tank, see Technical Instruction Document TID-0074.
