Operational Conditions

30 seconds if no further buttons are pressed. After 30 seconds the control will go back to “Sleep” mode.

2.Release both of the temperature adjustment buttons.

A.To decrease the temperature press and release the “COOLER” button until the desired setting is reached.

B.To increase the temperature press and release the “HOTTER” button until the desired setting is reached.

NOTE: Holding down the button will not continue to lower or raise the temperature setting. The button must be pressed and released for each temperature change desired.

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance. NOTE: During low demand periods when hot water is not being used, a lower thermostat setting will reduce energy losses and may satisfy your normal hot water needs. If hot water use is expected to be more than normal, a higher thermostat setting may be required to meet the increased demand. When leaving your home for extended periods (vacations, etc.) turn the temperature dial to its lowest setting. This will maintain the water at low temperatures with minimum energy losses and prevent the tank from freezing during cold weather.

Condensation

Moisture from the products of combustion condenses on the tank surface and the outside jacket of the water heater and forms drops of water which may fall onto the burner or other hot surfaces. This will produce a “sizzling” or “frying” noise. This condensation is normal and should not be confused with a leaking tank. Condensation may increase or decrease at different times of the year.

High efﬁcient energy saver water heaters will produce larger amounts of condensation on initial start-up or when a large amount of hot water is being used. Do not confuse this with a “tank leak”. Once the water reaches a temperature of 120°F (49°C) and the tank warms up (usually 1-2 hours), the condensation will stop.

CAUTION - PROPERTY DAMAGE HAZARD IMPORTANT: It is always recommended that a suitable metal drain pan be installed under the water heater

to protect the area from water damage resulting from normal condensation production, a leaking tank or piping connections. Refer to “Location Requirements” section

Water Heater Sounds

During the normal operation of the water heater, sounds or noises may be heard. These noises are common and may result from the following:

1.Normal expansion and contraction of metal parts during periods of heat-up and cool-down.

2.Condensation causes sizzling and popping within the burner area and should be considered normal.

3.Sediment buildup in the tank bottom will create varying amounts of noise and may cause premature tank failure. Drain and ﬂush the tank as directed under “Draining and Flushing”.

Smoke/Odor

The water heater may give off a small amount of smoke and odor during the initial start-up of the unit. This is due to the burning off of oil from metal parts of a new unit and will disappear after a few minutes of operation.

Safety Shut-off

This water heater is designed to automatically shut-off in the event of the following:

1.The water temperature exceeds 180°F (83°C.)

2.A blockage occurs in the combustion chamber air inlet, the ﬂue gas exhaust outlet, or both the inlet and outlet.

3.The blower fails to operate or operates improperly.

A high temperature limit switch or ECO (Energy Cut Off) in the tank is used to shut off the unit if the water temperature exceeds 180°F (83°C.) The ECO is a single use switch and requires complete replacement of the entire thermostat.

If the ECO should actuate, the water heater cannot be used until the thermostat is replaced by a qualiﬁed person. Contact your local dealer for service information.

Anode Rod/Water Odor

Each water heater contains at least one anode rod, which will slowly deplete while protecting the glass-lined tank from corrosion and prolonging the life of the water heater. Once the anode is depleted, the tank will start to corrode, eventually developing a leak. Certain water conditions will cause a reaction between this rod and the water. The most common complaint associated with the anode rod is a “rotten egg smell” produced from the presence of hydrogen sulfide gas dissolved in the water. IMPORTANT: Do not remove this rod permanently as it will void any warranties. The parts list includes a special anode that can be ordered if water odor or discoloration occurs. NOTE: This rod may reduce but not eliminate water odor problems. The water supply system may require special aeration or chlorination equipment from a water conditioning company to successfully eliminate all water odor problems.

The use of a water softener may decrease the life of the water heater tank.

The anode rod should be removed from the water heater tank every 3 years for inspection. The following are typical (but not all) signs of a depleted anode rod:

•The majority of the rods diameter is less than 3/8”.

•Signiﬁcant sections of the support wire (approx. 1/3 or more of the anode rod’s length) are visible.

If the anode rod show signs of either or both it should be replaced. NOTE: Whether re-installing or replacing the anode rod, check for any leaks and immediately correct if found.

In replacing the anode:

1.Turn off gas supply to the water heater.

2.Shut off the water supply and open a nearby hot water faucet to depressurize the water tank.

3.Drain approximately 5 gallons of water from tank (Refer to the “Draining and Flushing” section for proper procedures). Close drain valve.

4.Remove old anode rod.

5.Use Teﬂon® tape or approved pipe sealant on threads and install new anode rod.

6.Turn on water supply and open nearby hot water faucet to purge air from water system. Check for any

leaks and immediately correct any if found.

7.Restart the water heater as directed under the “Operating Your Water Heater” section. See the “Repair Parts Illustration” section for anode rod location.
