Setting the Unit
The unit must be installed on a 4 inch to 6 inch housekeeping pad (see NOTE below) to ensure
proper condensate drainage. If anchoring the unit, refer to the dimensional drawings in
Appendix F for anchor locations. Two lifting tabs are provided at the top of the heat exchanger.
Figure 2-2 shows the location of the tab on the top-left side. The second tab is located on the
top-right side of the heat exchanger. USE THESE TWO TABS TO LIFT AND MOVE THE UNIT.
Remove the top panel from the unit to provide access to the lifting tabs. Remove the four (4) lag
screws securing the unit to the shipping skid. Lift the unit off the shipping skid and position it on
the 4 inch to 6 inch housekeeping concrete pad (required) in the desired location.
NOTE:
When using the AERCO Condensate Neutralizer Tank for proper
condensate drainage, the Neutralizer Tank must be stored in a pit, OR the
boiler and AERCO Condensate Trap must be elevated higher than 4”
above the floor. See Condensate Tank instructions in TID-0074 for details.
WARNING
WHEN LIFTING OR MOVING THE BOILER:
•
DO NOT MANIPULATE THE BOILER USING THE GAS TRAIN OR
BLOWER
•
WHEN USING THE LIFTING TABS, ENSURE THERE IS NO LOAD
PLACED ON THE GAS TRAIN OR BLOWER

In multiple unit installations, it is important to plan the position of each unit in advance. Sufficient
space for piping connections and future service/maintenance requirements must also be taken
into consideration. All piping must include ample provisions for expansion
.
