Regular maintenance will keep the water heater operating at peak efficiency.

The tank can fail prematurely from an accumulation of lime and sediment on the bottom and tubes, excessive pressure and/or corrosion.

Prevention will appreciably extend the life of the water heater. Lime and sediment accumulations can be controlled by softening the water. Inspect the tank every six months by draining, removing the hand hole cover and making a visual check of the interior. Remove lime or sediment with a commer- cial lime dissolving chemical or scrape loose the deposit and flush it away through the hand hole or drain.

Excessive pressure is controlled by the pressure relief valve. Water expands when heated; if it can- not expand into the cold water line because of a check valve, the pressure relief valve opens and dumps the extra water. If the relief valve is faulty or none has been installed, the tank can fail due to this excessive pressure. Open the relief valve at least once a year to make sure the seat is not stuck. Caution: Before opening the relief valve, be certain the discharge line directs the water away from the outlet to avoid contact with the water.

Magnesium anode rods are installed in the head of the tank to help prevent corrosion. When inspecting the tank interior for lime, also inspect the anode rods. When the original diameter of any of the anode rods has eroded to about one-third it should be replaced.

Freezing: If the water heater is to be shut off during cold weather, the tank and water lines must be drained to prevent freezing, which will crack the tank. Open the relief valve test lever annually.

The warranty will be invalid if the tank fails due to excessive pressure, accumulation of lime or sedi- ment, corrosion or freezing.

Clean the oil burner nozzle annually and reset the electrodes. Replace the filter cartridge on the oil supply line filter annually.
