WARNING

Hydrogen gas can be produced in the hot water system served by

this water heater when there has been no usage for a long period of

time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY

FLAMMABLE. Therefore, to reduce the risk of injury under these

conditions, it is recommended that the hot water faucet be opened for

several minutes at the kitchen sink before using any electrical

appliance connected to the hot water system. If hydrogen is present,

there will probably be an unusual sound, such as air escaping

through the pipe, as the water begins to flow. There should be NO

smoking or open flame near the faucet at the time it is open.

CAUTION

INCREASING THE THERMOSTAT SETTING ABOVE THE PRESET

TEMPERATURE MAY CAUSE SEVERE BURNS AND CONSUME

EXCESSIVE ENERGY. HOTTER WATER INCREASES THE RISK OF

SCALD INJURY.

This water heater can deliver scalding temperature water at any faucet in the

system. Be careful whenever using hot water to avoid scalding injury. Certain

appliances, such as dishwashers and automatic clothes washers, may

require increased temperature water. By setting the thermostat on this water

heater to obtain the increased temperature water required by these

appliances, the potential for scald injury is increased. To protect against

injury, install an anti-scald tempering valve in the water system. Th

is valve

will reduce the point of discharge water temperature by mixing cold and hot

water in branch supply lines. Anti-sealed tempering valves can be obtained

from your local plumbing supplier. Please consult a plumbing professional.
