Operating the water heater CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system.
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. To avoid any unintentional changes in water temperature settings, the combination gas control (thermostat) has a tamper resistant feature for changing the temperature setting. To change the temperature setting follow these instructions. 1.
Sequence of Operation During initial start-up or a call for heat, the control will verify the vacuum switch is open. Once the control verifies the vent pressure switch is open, the control will energize the blower motor for the pre-purge sequence (approximately 5 seconds). The control will verify that the vent pressure switch has closed, ensuring that the blower is functioning properly and that the venting system is not blocked.
Care and Cleaning of the Water Heater Draining the Water Heater ! CAUTION: Shut off gas to the water heater at the manual gas shutoff valve before draining water. ! DANGER: Before manually operating the temperature and pressure relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage.
! DANGER: Combustible materials, such as clothing, cleaning materials, or flammable liquids, etc., must not be placed against or next to the water heater. Housekeeping Make sure the Flammable Vapor Sensor is not blocked or obstructed. DO NOT expose the Flammable Vapor Sensor to water, solvents or cleaning agents.
