    Installing the New Water Heater (cont’d) Installation Checklist BEFORE OPERATING THE WATER HEATER: 1. Check the gas line for leaks. a. Use a soapy water solution. DO NOT test for gas leaks using a match or open flame. b. Brush the soapy water solution on all gas pipes, joints and fittings.
  • Page 21: Operating

    Operating This water heater is equipped with an electrically operated venting system and electronic control. For the burner to come on, the water heater thermostat must call for heat. Then the system will begin sequencing, each section prov- ing itself before gas is allowed to flow to the burner. BEFORE THE WATER HEATER WILL OPERATE: 1.
  • Page 22: Before Lighting

    Operating (cont’d) WARNING BEFORE LIGHTING [PROPANE (L.P.) GAS WATER HEATERS]: Propane (L.P.) gas is heavier than air. Should there be a leak in the system, the gas will settle near the ground. Basements or crawl spaces, closets and areas below ground level will serve as pockets for the accu- mulation of this gas.
  • Page 23: For Your Safety Read Before Operating

    Operating (cont’d) FOR YOUR SAFETY READ BEFORE OPERATING If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner.
  • Page 24: Temperature Regulation

    Temperature Regulation Due to the nature of the typical gas water heater, the water temperature in certain situations may vary up to 30°F high- er or lower at the point of use such as, bathtubs, showers, sink, etc. This means that when the temperature adjustment dial is set at the mark approximating 120°F, the actual water tem- perature at any hot water tap could be as high as 150°F or as low as 90°F.
  • Page 25: For Your Information

    For Your Information Start Up Conditions CONDENSATION Whenever the water heater is filled with cold water, a cer- tain amount of condensation will form while the burner is on. A water heater may appear to be leaking when in fact the water is condensing.

    For Your Information (cont’d) Operational Conditions (cont’d) “AIR” IN HOT WATER FAUCETS WARNING HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive.
  • Page 27: Periodic Maintenance

    Periodic Maintenance Venting System Inspection At least once a year a visual inspection should be made of the venting system. You should look for: 1. Obstructions which could cause improper venting. The combustion and ventilation air flow must not be obstructed. 2.
