General Instructions

To Fill 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.
