Flushing Water Heater
1. Turn OFF the water heater electrical disconnect switch.
2. Open the drain valve and allow water to flow until it runs clean.
3. Close the drain valve when finished flushing.
4. Turn ON the water heater electrical disconnect switch.
Filling the Water Heater
1. Close the water heater drain valve. This water
heater utilizes a ball valve; when closing the
valve, the stem will spin indefinitely. Confirm it
is closed by ensuring the slot on the stem is
perpendicular to the valve body. If alternative
water connections are provided but not used,
make certain they are plugged (i.e. space
heating & alternate top connections).
2. Open the cold water supply shut-off valve.
3. Open several hot water faucets to allow air to escape from the system.
4. When a steady stream of water flows from the faucets, the water heater is filled. Close the faucets and
check for water leaks at the water heater drain valve, combination temperature and pressure relief valve
and the hot and cold water connections.
