outlined on page 6. Failure to inspect the anode regularly and replace if necessary could
result in damage to the water heater. If this unit is installed and maintained according to
the instructions and conditions in this manual, this product will last for a long time.
1. Close domestic water isolation valves.
2. Drain the water heater completely and allow it to cool off.
3. Remove the anode cover on the front of the unit. See figures on pages 2 and 3. The
temperature control can be turned to the side to allow easier access.
4. After the water heater has drained and cooled, remove the anode using a 1 ¾” 6-­‐point
socket and a breaker bar.
5. Inspect the anode and replace if needed. The anode should be replaced when more
than 6” of core wire is exposed. The anode should be replaced with a Heat-­‐Flo supplied
anode only. See above. The brass hex on the anode is 1 ¼ NPT and installs into a 1 ¼
stainless half coupling on the shell of the tank. This part will need to be properly Teflon
taped and coated with a quality Teflon based pipe sealant.
6. Replace the inspection cover.
7. Refill the water heater, and restore to operation.
8. Verify operation of boiler and water heater.
