WARNING

Have leaks xed at once by a qualied service technician. Failure to comply could result in substantial property damage, severe personal injury, or

death.

To avoid water damage or scalding due to relief valve operation, a discharge line must be connected to the valve outlet and directed to a safe

place of disposal. This discharge line must be installed by a qualied service technician or heating/plumbing installer in accordance with the water

heater installation manual. The discharge line must be terminated so as to eliminate possibility of severe burns or property damage should the

valve discharge.

Operate Pressure Relief Valve

● Before proceeding, verify that the relief valve outlet has been piped to a safe place of discharge, avoiding any possibility of scalding from hot

water.

● Shut power off to the water heater. To avoid scalding, wait for water heater to cool before operating the relief valve.

6. Reinstall the cold water inlet filter.

7. Restore water service to the water heater by opening the isolation valves, or turning on the main water valve.

8. Turn on the gas valve. Turn on electrical power to the water heater and press the Power button to turn the water heater on.

●List the relief valve lever. If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief valve discharge pipe

to ensure that the valve does not weep after the line has had time to drain. If the valve weeps, lift the lever again to attempt to clean the valve

seat. If the valve does not properly seat and continues to weep, contact a qualified service technician to inspect the valve and system.

● If water does not flow from the valve when you completely lift the lever, the valve or discharge line may be blocked. Immediately shut the

water heater down per instructions on page 2 and call a qualified service technician to inspect the valve and system.

● If relief valve seats properly, restore power to the water heater. Observe operation for five minutes and ensure it operates properly.

Check the Burner

Clean the exterior of the burner.

Cleaning the Cold Water Inlet Filter (Draining the Water Heater)

1. Place a bucket under the appliance to collect the residual water inside the water heater.

2. Press the Power button on the control panel to turn off the electrical power to the water heater. Then turn off the gas valve.

3. Valve off the water heater from the system. If the water heater cannot be isolated from the system, turn off the main water valve. Open the hot

water faucets in the system to aid in draining the system.

5. Use a coin to remove the cold water inlet lter. Then clean it with a toothbrush and clean running water. See Figure 56.
