Fig. 1 Tank Tap
Shown on the next page are options for
connecting the water lines from the ACWH
to the water tank. One option shown shows
the use of the Tank Tap Adapter (shown in fig
1). This adapter is designed to use the boiler
drain port as both the supply and return to the
ACWH while retaining its drain
functionality. Detailed Tank Tap instructions
follow at the end of this document. If you did
not order a Tank Tap with your unit, use the
plumbing method.
9. Shut off power to the water heater, if electric, at the fuse or circuit breaker
panel. If it’s a gas-fired water heater, close off the gas valve found ahead of
the water heater burner and controls. If gas, be sure you know how to turn
the gas on and off (including resetting the igniter safety switch) before doing
this.
Shut off the cold water supply to the water heater.
10. Empty the water heater by attaching a hose to the drain valve and
opening the pressure relief valve. If the draining water appears dirty or
cloudy, you may have to refill the water heater and drain it again, until the
draining water appears clear and free of sediment.
NOTE:
Some water heaters are already plumbed with stubs extending from
the cold water line and the hot water delivery line. Use the cold
water stub, do not use the hot water stub.
