3.16 AMR 119-Gallon Buffer Tank Installation
Installing the AMR 119-Gallon Buffer Tank
WARNING!
Affixing the base extension to the base is required for 119-gallon tank installation.
1.
Remove the two tank clamps from REAR of main base and relocate them to base extension
(P/N 39209) using the existing hardware (Figure 3-14).
2.
Remove the two tank clamps that are closer to the main unit and relocate both to next set of
holes toward the rear using existing hardware (Figure 3-14).
NOTE:
One or more of the tank clamps may be temporarily removed, to allow sliding the tank in from
the side. Ensure any clamps removed are reinstalled after tank placement as shown.

3.
Affix extension (P/N 39209) to rear of AMR base by aligning tab holes of extension with
holes on base sides (Figure 3-14). Use lock nuts (P/N 56034), hex bolts (P/N 1216990), and
washers (P/N 53050) to secure both sides, with bolt/washer on outside, and nut on inside.
4.
Adjust threaded tank clamps (Figure 3-14) to allow maximum clearance for tank.
5.
Center the tank as shown in Figure 3-15. Ensure that the water connections are facing the
rear of the AMR water heater as indicated in Figure 3-16.
6.
Tighten all four tank clamps against the tank (Figure 3-16).
