Operating the water heater.
Water Temperature Setting…
Maximum water temperatures occur just after the burner has shut off. To determine the water temperature, turn on a hot water faucet and place a thermometer in the water stream.
The wide arrow mark near CAUTION on the rim of the temperature dial, represents an approximate water temperature of 120°F (49°C).
The reference mark, to the left, represents an approximate water temperature of 125°F (52°C).
Each reference mark above or below these points indicates an approximate change of 5°F (3°C).
To adjust the temperature, turn the temperature dial to an initial setting of 120°F (49°C).
A condition known as “stacking” or “layering” can occur when a series of short and frequent hot water draws are taken.
The hottest temperature water will be at the top of the tank, closest to the outlet pipe delivering hot water to the home.
Stacking can cause this top layer of water to be hotter than the water toward the bottom of the tank near the gas control (thermostat).
Therefore, always remember to test the water temperature with your hand before use and remember that hotter water increases the risk of scald injury.
Also, always supervise young children or others who are incapacitated.
The gas control (thermostat) is constructed with a built in safety
The gas control (thermostat) is also equipped with a single use gas shut off device that will shut off the gas supply to the burner if the water heater exceeds normal operating temperatures. Refer to the (Before You Call For Service) section of this manual, or contact your dealer.
!WARNING: Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.
If the water heater has been subjected to fire, flood or physical damage, turn off the manual gas control
