Important: Adjusting the thermostat past the 120°F setting on the temperature dial (see figure 22) will increase the risk of scald injury. Hot water can produce first degree burns within: 120°F (49°C) more than 5 minutes 130°F (54°C) at 20 seconds 140°F (60°C) at 3 seconds 150°F (66°C) at 1-1/2 seconds 160°F (71°C) at less than 1 second Emergency Shut Down Important: If overheating occurs or the gas supply fails to shut off, close the manual gas supply valve. Turn off the electrical supply to the unit and close the cold water supply valve. Do not operate the water heater again until it has been thoroughly checked by an authorized service technician. Water temperature over 125°F can cause severe burns instantly or death from scalds. Children, disabled and elderly are at highest risk of being scalded. See instruction manual before setting temperature at water heater. Feel water before bathing or showering. Temperature limiting valves are available. OPERATIONAL CONDITIONS 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. 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”. Safety Shut-Off (Pressure Switch) This water heater is equipped with a pressure switch that protects the unit by shutting it down in the event that: • A blockage occurs in the combustion air inlet, the flue gas exhaust outlet, or both the inlet and outlet. • The condensate line freezes and the condensate “backs up” and fills the exhaust outlet. • The blower fails to operate, or operates improperly. • The unit begins to operate at an abnormally low input level. Energy Cut-Off (ECO) A high temperature limit switch, or ECO, is used to shut down the water heater if the water temperature exceeds 203°F. The ECO will automatically reset when the temperature cools sufficiently. If the ECO shuts down the heater repetitively, contact a qualified professional for service. MAINTENANCE Draining and Flushing It is recommended that the tank be drained and flushed every 6 months to remove sediment which may buildup during operation. 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 supply at the Manual Gas Shut-off Valve. Turn off the electrical supply to the water heater 2. Close the cold water inlet valve. 3. Open a nearby hot water faucet. 4. Open the access door at the bottom of the heater, then 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. 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. Close the cold water inlet valve. 6. Open the water heater drain valve and allow all the water to drain from the tank. 7. Flush tank to remove sediment Note: For water heaters with a hand hole clean-out follow steps 8-11. Figure 23: Hand Hole Clean-out 8. Remove screw holding the outer hand hole clean-out cover. Then carefully remove the insulation covering the clean-out plug. Using a 1/2” square drive ratchet open the clean-out plug (see figure 23.) Note: After removing the clean-out plug inspect the O-ring for damage, replace if necessary. 9. Using a Wet/Dry shop vacuum clean any debris from the tank. 10. Lubricate O-ring with a food grade oil. Then replace and securely tighten the clean-out plug. 11. Replace the insulation and cover plate. 12. Close the drain valve, replace access door, refill the tank, and restart the 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. Temperature and Pressure Relief Valve Manually operate thetemperature and pressurerelief valve at least once a year to make sure it isworking properly. To prevent water damage, the valvemust be properly connectedto a discharge line whichterminates at an adequatedrain. Standing clear ofthe outlet (dischargedwater may be hot), slowlylift and release the lever handle on the temperature andpressure relief valve to allow the valve to operate freelyand return to its closed position (see figure 24). If the valvefails to completely reset and continues to release water, immediately shut off the manual gas valve and the cold water inlet valve, and call a qualified service technician. Figure 24 MAINTENANCE OF YOUR WATER HEATER 3 Month Inspection At least every 3 months, a visual inspection should be made of the combustion air inlet as well as the exhaust and water piping. Check the water heater for the following: • Obstructions, damage, or deterioration in the venting system. Make sure the exhaust and combusti...
