Q:7 Water flow too low.

The cause for this could be that there are restrictions in the plumbing. To correct this, make sure that the heater’s inlet filter screen, faucet aerators, showerheads and whole house filters are clear of debris. Also check if the proper flow on the outlet side of the heater with the hot water pipe disconnected. Maximum flow rates for each unit are: AE-115 = 2.3gpm, AE-125 = 3.5gpm.

Another reason could be that the water supply pressure too low. The incoming water supply should at least be at 30psi while for well systems, the recommended pressure range is 30-50psi.

Also check if the outlet shut-off valves are set too low. You can adjust the installer supplied outlet valve in three easy steps. First, open both the installer supplied inlet and outlet shut-off valves. (You would need to install, if they aren't already there). Next, open hot water on the highest flowing hot water fixture served by the heater, like a bathtub, for instance. Finally, slowly close the outlet shut-off valve, to ease the water flow rate until the desired water temperature is reached.
