DO NOT ATTEMPT TO OPERATE THE BOILER if this situation occurs. Shut the boiler off before performing all the steps shown in "TO TURN OFF GAS TO APPLIANCE" section of the Lighting and Operating Instructions. Contact a qualified service agent to inspect the unit and vent system and correct the problem. VENT SYSTEM The flue products are corrosive in nature and if the boiler is vented horizontally the flue gases are at a higher pressure than the surrounding air pressure. Inspection of the boiler and vent system is necessary to insure that flue gas leakage to the surrounding area does not occur. Inspect the external surfaces of the vent system every 3 months for corrosion and leakage. Inspect the vent terminations for corrosion and foreign matter which may be blocking the exhausting flue products. Call a qualified service agent to replace or repair any corroded or leaking parts. Qualified service agent must inspect internal surfaces of the vent system and the boiler at least once a year. BURNER SYSTEM To maintain safe operation and the greatest efficiency for the boiler, observe the burner flame through the observation port on the left jacket panel, once a month for proper flame characteristics. The burners should display the following characteristics: • Provide complete combustion of gas. • Cause rapid ignition and carry over across all burners and across the entire burner. • Give quiet operation during ignition, burning and extinction. • Cause no excessive lifting of flames from the burner ports. If the preceding characteristics are not evident, check for accumulation of lint or other foreign material that restricts the inlet air or burner ports. Ensure there is the proper amount of air to the burner. Flame lifting from the burner is caused by too much air to the burner. The burners must be inspected by a qualified service technician at least once a year. DO NOT STORE COMBUSTIBLE MATERIALS, GASOLINE, OR OTHER FLAMMABLE VAPORS, LIQUIDS IN THE AREA OF THE APPLIANCE. NONCOMPLIANCE MAY RESULT IN FIRE OR EXPLOSION. DO NOT OBSTRUCT THE FLOW OF COMBUSTION OR VENTILATION AIR TO THE APPLIANCE. CHEMICAL VAPOR CORROSION Boiler corrosion and component failure can be caused by airborne chemical vapors. Spray can propellants, cleaning solvents, refrigerants, calcium or sodium chloride (water softener salts), waxes, and process chemicals are typical compounds that are potentially corrosive. These materials are corrosive at very low concentration levels with little or no odor to reveal their presence. Products of this sort should not be stored near the boiler. Air which is brought in contact with the boiler should not contain any of these chemicals. The boiler should be provided with air from outdoors when installed in environments having corrosive atmospheres. CIRCULATION PUMP Refer to the pump manufacturer's schedule of maintenance for frequency and method of lubricating the pump and motor. Inspect the pump once a month for leaky mechanical seals and/or O-rings a...
