SERVICE AND ADJUSTMENT

Draining and Flushing

It is recommended that the tank be drained and flushed every 6 months to remove sediment which may build up during operation. The water heater should be drained if being shut down during freezing temperatures. To drain the tank, perform the following steps:

1.Turn off the gas to the water heater at the manual gas shut- off valve and turn off the electrical power to the gas control/ thermostat valve.

2.Open a nearby hot water faucet until the water is not longer hot.

3.Close the cold water inlet valve.

4.Connect a hose to the drain valve and terminate it to an adequate drain or external to the building.

5.Open the water heater drain valve and allow all the water to drain from the tank. Flush the tank with water as needed to remove sediment.

6.Close the drain valve, refill the tank, and restart the heater as directed in this manual.

If the water heater is going to be shut down for an extended period, the drain valve should be left open.

IMPORTANT: Condensation may occur when refilling the tank and should not be confused with a tank leak.

Routine Preventive Maintenance

At least annually, a visual inspection should be made of the venting and air supply system, piping systems, and main burner. Check the water heater for the following:

•Obstructions, damage, or deterioration in the venting system. Make sure the ventilation and combustion air supplies are not obstructed.

•Clean any dust or debris from the screen of the air intake chamber.

Temperature and Pressure Relief Valve

• Temperature-pressure relief valve must comply with ANSI Z21.22-CSA 4.4 and ASME code.

• Properly sized temperature- pressure relief valve must be installed in opening provided.

• Can result in overheating and excessive tank pressure.

• Can cause serious injury or death.

Manually operate the temperature and pressure relief valve at least once a year to make sure it is working properly. To prevent water damage, the valve must be properly connected to a discharge line which terminates at an adequate drain. Standing clear of the outlet (discharged water may be hot), slowly lift and release the lever handle on the temperature and pressure relief valve to allow the valve to operate freely and return to its closed position. See Figure 34. If the valve fails to completely reset and continues to release water, immediately shut off the electrial power, manual gas control valve and the cold water inlet valve and call a qualified technician.
