Filling the Water Heater
Filling the Reliance 606 water heater is a critical step to ensure proper operation and prevent damage. Before filling, ensure the tank is completely empty and all valves are in the correct position. Open the cold water inlet valve and allow the tank to fill with water. Check for leaks at all connections during this process. Once the tank is full, turn on the hot water faucet nearest to the heater to verify water flow. For gas models, ensure the gas supply is turned off during filling to prevent accidental ignition. If the water heater is equipped with a drain valve, inspect it for proper function and replace the washer if necessary. Never operate the heater unless it is completely full of water, as this can cause damage to the heating elements or tank. After filling, follow the lighting instructions provided in the manual to restart the heater. Regularly draining and refilling the tank can help maintain efficiency and extend the lifespan of the appliance.
