3. For Honeywell Valve: Turn gas control knob clockwise to "Off". Make sure knob rest against stop. For Robertshaw Valve: Push in and move gas control lever to "Off" position. HONEYWELL PILOT CAUTION: Should overheating occur or the gas supply fails to shut off, DO NOT turn off or disconnect the electrical supply to the pump. Instead, shut off the gas supply at a location external to the appliance. Failure to observe this precaution may aggravate the overheated condition resulting in possible damage to the boiler and injury to the user. INSPECTION AND MAINTENANCE PROCEDURES It is a good practice to make a periodic inspection of the boiler. It is recommended that the home owner or user check's the boiler after the first and third month of operation, and then on an annual basis, or more often if desired. It is also recommended to have a qualified service agency check the boiler before each heating season, or at anytime there may be an indication of a problem. DANGER: Keep boiler area clear and free from combustibles and flammable materials. Do not obstruct the flow of combustion and ventilating air into the boiler enclosure. Failure to observe these safety precautions can cause fire, explosion, or asphyxiation. BLUE FLAME Fig. #9295 3 1. Burner Inspection. Clean the main burners and air louvers of dust, lint and debris. With burner in operation, make a visual check of the burner flame and the pilot flame (when equipped). Yellow flames indicate some restriction of combustion air openings. A bright orange, luminous flame is not normal and can cause sooting under prolonged operation. Should this condition be observed, contact immediately a qualified service agency to correct the problem. 2. Venting System Inspection. Visually inspect the venting system. Make sure the vent connections are secure and have not become disengaged. Look for any indication of corrosion, or carbon (soot) streaks which could cause leakage of products of combustion into the living space. Inspect the vent terminal outside the building. Make sure it is not damaged to cause blockage or restriction of the flue gas. Observe for any indication of soot. The presence of soot accumulation in the vent terminal would indicate an abnormal operating condition. This should be investigated and corrected by a qualified service agency. SOOT CORROSION DISENGAGED Fig. #8204.0 3. Circulator (Water Pump) Inspection. The circulator is permanently lubricated and thus, will not require any lubrication. Inspect for evidence of water leakage. This should be corrected to prevent any possible damage to electrical components of the boiler. CAUTION: In case of a prolonged power failure during freezing weather conditions, boiler and piping system must be drained completely to avoid possible damage to the heating system. To prevent the potential freezing damage to the heating system, it is recommended that the following system shut down procedure be performed. SYSTEM SHUT DOWN PROCEDURE 1. Set the room thermo...
