Setting the Unit

2.4.2

The unit must be installed on a 4 inch to 6 inch housekeeping pad 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.

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

.

If installing a Combination Control Panel (CCP) system, it is important to identify the

Combination Mode Boilers in advance and place them in the proper physical location. Refer to

Chapter 5 for information on Combination Mode Boilers.
