It is recommended that lower water temperatures be used to avoid the risk of scalding. It is further recommended, in all cases, that the water temperature dial be set for the lowest temperature that satisfies your hot water needs. This will also provide the most energy efficient operation of the water heater. The water temperature adjusting dial was factory set at the lowest temperature; all the way counterclockwise to the mechanical stop. Turning the dial counterclockwise decreases temperature and clockwise increases temperature. SETTING THE WATER HEATER TEMPERATURE AT 120°F (49°C) (APPROX. "HOT" MARK ON FACE OF THE TEMPERATURE ADJUSTING DIAL) WILL REDUCE THE RISK OF SCALDS. Some states require settings at specific lower temperatures. Figure 10 shows the approximate water temperatures produced at various thermostat dial settings. Short repeated heating cycles caused by small hot water uses can cause temperatures at the point of use to exceed the thermostat setting by up to 20°F (11°C). If you experience this type of use you should consider using lower temperature settings to reduce scald hazards.

FOR YOUR SAFETY, WATER HEATER SERVICE SHOULD BE PERFORMED ONLY BY A QUALIFIED SERVICE TECHNICIAN. READ THE GENERAL SAFETY INFORMATION SECTION FIRST. USERS OF THIS APPLIANCE SHOULD BE AWARE THAT GAS COMPONENTS WEAR OUT OVER A PERIOD OF TIME. THE GAS CARRYING COMPONENTS OF THIS APPLIANCE SHOULD BE INSPECTED FOR PROPER OPERATION PERIODICALLY BY A QUALIFIED SERVICE TECHNICIAN. MAIN BURNER Check main burner every 12 months for proper flame characteristics. This is done by removing door(s) on heater. The main burner should provide complete combustion of gas; ignite rapidly; give reasonable quiet operation; cause no excessive flame lifting from burner ports. Make sure that the flow of combustion and ventilation air is not blocked. If proper flame characteristics are not evident, check for accumulation of lint or other foreign material that restricts or blocks the air openings in the heater or burner. Also check AIR REQUIREMENTS. WARNING SOOT BUILD-UP INDICATES A PROBLEM THAT REQUIRES CORRECTION BEFORE FURTHER USE. Consult with a qualified service technician. Should the main burner or burner air openings require cleaning, turn the control switch to “OFF” position and allow the burner to cool. Remove the burner and clean with a soft brush. Clean main burner orifice with a suitable soft material. 14 4. The pressure switch part inside the power venter must be open and HIGH TEMPERATURE CUT-OFF SWITCH The thermostat has a built-in temperature cut-off switch (TCO), which will shut off gas to the burner in case of excessive water temperature. If the TCO functions the valve will flash 4 times and the valve must be replaced. It is important that a serviceman be called to determine the reason for limit operation and thus avoid repeated thermostat resetting. Lower the temperature adjustment dial setting on control. VENTING SYSTEM HAVE VENTING SYSTEM CHECKED EVERY SIX MONTHS FOR OBSTRUCTIONS AND/OR DETERIORATION IN VENT PIPING. A. Insofar as is practical, close all doors, windows and air inlets to the building. Turn on all exhaust fans (range hood, bathroom exhaust, etc.) so they will operate at their maximum speed. Close fireplace dampers. B. Turn water temperature adjusting knob to full, counterclockwise and open water faucet if necessary to keep burner in operation. C. “CHECKING THE DRAFT.” Operate the water heater for several minutes and check to see if it is venting properly by passing a lit match or paper near the opening of the Air Supply Box. If the draft is proper, the match flame will be drawn into the Air Supply Box (fig 11). If not, the combustion products will tend to extinguish the flame. If an improper draft exists, do not operate the water heater until proper adjustments or repairs are made to provide adequate draft through the gas vent. D. Next, turn on all other fuel burning appliances within the same room so they will operate at their full input. Repeat step C above. FIGURE 11 POWER VENTER MAINTENANCE The BTF-75 must be inspected quarterly. Points of inspection are: 1. MOTOR - Motor must rotate freely. This is a sealed motor and no oiling is required. 2. WHEEL - Wheel must be clean of soot, ash or any other coating which inhibits either rotation or air flow. Remove all foreign material from vent system before operating. 3. AIR SUPPLY BOX-Every month check operation and make sure nothing is blocking dilution air entrance. free from deposits of soot, carbon, etc. For sa...
