Installation / Operation Instruction Manual

Operating Instructions continued-
For the most energy efficient operation, adjust the aquastat for
the minimum water temperature necessary to meet domestic
hot water needs. Refer to Figure 8. Use a small flat screwdriver
to rotate the temperature dial through the hole directly below
the temperature indication window. The temperature setting is
aligned with the notch in this window. IT IS NOT NECESSARY
TO REMOVE THE COVER TO ADJUST THE
TEMPERATURE SETTING. THE AQUASTAT COVER
SHOULD NEVER BE REMOVED WITHOUT ELECTRICITY
BEING FIRST DISCONNECTED.
Figure 8 - Aquastat Control
After the indirect-fired water heater completes a heat-up cycle,
check the water temperature at a faucet. Allow enough water to
flow to ensure that the water temperature reflects the tank
temperature. Adjust the water heater’s temperature setting as
necessary.
CAUTION
Before adjusting the aquastat, turn OFF all power
supplied to the indirect-fired water heater.
