If this occurs, do not operate the water heater until proper adjustments or repairs are made to the vent pipe system. Figure 14: Vent Draft Test Burner Flames Inspect the burner flames through the viewport and compare them to the drawings in Figure 15. A properly operating burner should produce a soft blue flame and be about 2.(51mm) to 2 -1/2.(64mm) in height. Blue tips with yellow inner cones are satisfactory. The tips of the flame may have a slight yellow tint. The flame should not be all yellow or have a sharp blue-orange color. Contaminated air may cause an orange colored flame. Contact a qualified service technician if the flame is not satisfactory. Operational Conditions 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. Important: It is always recommended that a suitable 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. Under no circumstances is the manufacturer to be held responsible for any water damage in connection with this water heater. 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 pilot flame is extinguished for any reason. 2. The water temperature exceeds 205°F (96°C). Figure 15: Pilot/Burner Flame 2 -2 1/2. 21 21 (Index) Index MAINTENANCE OF YOUR WATER HEATER Draining and Flushing It is recommended that the tank be drained and flushed every 6 months to remove sediment which may buildup during operation. Note: Warranty is null and void in the event lime & scale deposits are allowed to exceed two inches in depth. The water heater should be drained if being shut down during freezing temperatures. To drain the tank, perform the following steps: 1. Turn off the gas to the water heater at the manual gas shut-off valve and turn off electricity. 2. Close the cold water inlet valve. 3. Open a nearby hot water faucet. 4. Connect a hose to the drain valve and terminate it to an adequate drain. Note: The drain hose should be rated for at least 200°F (49°C). If the drain hose does not have this rating, open the cold water inlet valve and a nearby hot faucet until the water is no longer hot. 5. Open the water heater drain valve and allow all the water to drain from the tank. 6. Remove the screws holding the cleanout plate, then remove the plate for access. 7. Remove any lime, sediment, or scale from the tank. Be careful not to damage the glass lining. 8. Flush the tank with water as needed to remove any remaining sediment. 9. Check gasket on cleanout plate, replace if necessary. 10. Replace the cleanout plate and screws, tighten sufficiently. 11. Close the drain valve, refill the tank, and restart the water heater as directed under .Operating Your Water Heater.. If the water heater is going to be shut down for an extended period, the drain valve should be left open. Important: Condensation may occur when refilling the tank and should not be confused with a tank leak. Routine Preventative Maintenance At least annually, a visual inspection should be made of the venting and air supply system, piping systems, main burner, and pilot burner. Check the water heater for the following: • Obstructions, damage, or deterioration in the venting system. Make sure the ventilation and combustion air supplies are not obstructed. • Build-up of soot and carbon on the main burner and pilot burner. Check for a soft blue flame. • Leaking or damaged water and gas piping. • Presence of flammable or corrosive materials in the installat...
