x. FOREWORD reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at a nearby kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. THERE SHOULD BE NO SMOKING OR OPEN FLAME NEAR THE FAUCET AT THE TIME IT IS OPENED.
CALCULATING AMPERAGE/OVERCURRENT PROTECTION • Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan. • Water supply shut-off devices that activate based on the water pressure differential between the cold water and how water pipes connected to the water heater. • Devices that will turn off the gas supply to a gas water heater while at the same time shutting off its water supply. The heaters come from the factory in two configurations: 1.
Not more than three conductors in Raceway or Cable or Direct Burial (Based on Ambient Temperature of 30° C, 86° F. These ampacities relate only to conductors described in Table 310-13 in Code. For ambient temperatures over 30° C (86° F), see Correction Factors, Note 13 in Code.

OPERATION Figure 3 shows the approximate time-to-burn relationship for normal adult skin. The thermostats on your water heater have a linear relationship between degrees of angular rotation and the corresponding change in temperature. Thus rotating the temperature adjustment indicator 30 angular degrees will result in a 10 degree Fahrenheit change in water temperature.
Once a month the temperature and pressure relief valve should be checked to ensure that it is in operating condition. Lift the lever on the valve several times until the valve seats properly and operates freely. 3. Using a flat tip screwdriver, rotate the adjusting knob to the desired temperature setting. 4. Replace the covers and access panels, and turn on heater electrical supply. CAUTION THE WATER PASSING OUT OF THE VALVE DURING THIS CHECKING OPERATION MAY BE EXTREMELY HOT.
6. Look for leaking or open hot water faucets. valve in the inlet system will not permit the expanded hot water volume to equalize pressure with the main. A relief valve must release this water or the water heater or plumbing system will be damaged. WATER IS TOO HOT 1. Refer to TEMPERATURE REGULATION section. When such a condition is encountered, local codes or inspection agency should be consulted to determine which system is acceptable in your area. These may consist of: WATER HEATER MAKES SOUNDS 1.
LEAKAGE CHECKPOINTS Instructions: Use this illustration as a guide when checking for sources of water leakage. You or your dealer may be able to correct what appears to be a problem. NOTE: Cover and Insulation shown removed to reveal tank top Where possible remove or lift top cover to examine threads of fittings installed into tank for evidence of leakage. Correct fitting leaks as necessary. Relief Valve Condensation and dripping may appear on pipes when cold water temperature is low.
