•Check that you have not just run out of hot water due to heavy demand. If this is a routine problem, it may indicate an under-sized water heater.

•Have your gas company check input rate and water heater operation

•The E.C.O. may have tripped open (LED indicator on constantly). See E.C.O. below.

Energy Cut-off Control (E.C.O.)

This water heater is equipped with a control which has a built in E.C.O. (Energy Cut-off). The E.C.O. will shut the gas off, should the outlet water temperature exceed 200° F. If the E.C.O. has tripped, the entire gas control must be replaced. For gas control replacement, contact your local gas utility, or a qualified service

Water Heater Makes Noise

•During start up or under heavy use, condensation can drip on the burner causing a sizzling noise as the water is evaporated. This is normal and will stop once temperatures rise.

•Sediment, sand or scale can accumulate resulting in “rumbling” noises. Water heaters need to be flushed regularly to minimize buildup. Severe accumulations (more than 2" - 50 mm) can cause premature failure of the water heater and will void the warranty.

•Vent piping can vibrate if it is not supported properly. Ensure hangers and vibration isolators are properly installed.

Discolored Water

•Water rich in iron or other minerals can produce red or brown staining. Heating water generally worsens this situation.

•Black water can be an indication of organic contaminates in the water supply. This can be problematic in areas where the water is obtained from surface or contaminated sources. Organic particles can develop bacterial growth, causing potential health hazards. Contact your water supplier for proper filtration or water conditioning equipment. For bacterial problems contact your local health authority. See also “Hot Water Odor”

•A sudden appearance of rusty water can indicate the anode rod has been depleted. The remaining steel core wire may be corroding, releasing iron particles into the water. Inspect and replace as necessary.

Extended Non Use

technician. The replacement control must be an identical model to the control which has been removed.

Water Temperature is Too Hot

•Check that thermostat setting is not too high

•Water heaters used for dishwashers, space heating or laundry facilities generally require higher temperatures than domestic use. Install anti-scald tempering valves as instructed in the safety warnings

•If the problem persists, contact your dealer or gas supplier

Hydrogen gas can be produced by water heaters in service but on standby for long periods of time (generally two weeks or more). See safety warnings in the front of the manual Hydrogen gas is extremely flammable. Use caution in opening faucets.

Tank Flushing

Periodically (monthly) drain approximately 2 gallons (8 liters) from the tank through the drain valve. This will minimize sediment buildup on the tank bottom.

Caution: WATER WILL BE HOT.

If scale removal is being considered, contact your dealer for

proper procedures. DO NOT USE HYDROCHLORIC

ACID (HCL) based cleaners. Thoroughly flush after any chemical cleaning.

Vent Maintenance

Inspect the venting system periodically (minimum annually) to make certain that the venting passageways, vent terminal and blower assembly are free and unobstructed. Check that the vent connections are free and unobstructed, Check that the vent connections and vent joints are properly positioned and securely attached. In areas that have a high level of airborne particles (e.g. lint, sawdust, process smoke, etc.) Inspection and cleaning may need to be done more frequently.

Relief Valve Check

Inspect the relief valve annually to ensure proper operation. This involves opening the valve to check that it is flowing freely and that there are no blockages. Provide a bucket or drainage for the expelled water. Lift the lever and let it snap shut. The
