CAUTION: DO NOT RELIGHT PILOT OR START BURNER WITH COMBUSTION CHAMBER FULL OF GAS OR OIL VAPOR, OR WITH VERY HOT COMBUSTION CHAMBER.
1.Study the burner
2.Fill the water heater tank with water. Open the relief valve or a nearby hot water faucet to allow air in the tank to escape. Be sure all connections into the tank are tight as leaks at tank fittings will damage the insulation.
3.The top thermostat is a temperature limiting safety device set at 200°F. The thermostats are set at the factory at 130°F on the upper operating thermostat and 120°F on the lower operating thermostat. Adjustment may be made by turning the thermostat dial to the desired temperature.
CAUTION: TEMPERATURES HIGHER THAN 130? F INCREASE THE RISK OF SCALD INJURY.
CAUTION: CONDUCT THE FOLLOWING GAS TRAIN LEAKAGE TEST BEFORE
1.Using an appropriate bubble detection solution, thoroughly coat all gas train pipe connections. If any bubbles are detected, the leaking connection must be tightened, recoated and rechecked to assure stoppage of the leak.
2.Attach a manometer, to measure gas pressure, at the manual gas shutoff valve located just upstream of the gas train. Adjust gas train inlet pressure to the specified value (e.g. 14 in. W.C.), and tightly close the gas train manual shutoff valve closest to burner.
3.Reattach the manometer to the gas train manual shutoff valve at the burner and record the measured gas pressure in inches of water column (in W.C.). Measure gas pressure again after 15 minutes. If gas pressure has increased 0.5" W.C. or more, the gas leak must be isolated to one or more of the operating gas valves, for example, a solenoid actuated gas shutoff valve. After any leaking valve is replaced, the reassembled gas train must be leak tested again before
