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
•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
