Kenmore 5EWL.20, 4EW.90, 3EW.75, 3E W.65, 5EW1.75, 5EW2.00 Rules for Safe Installation and Opeiltion

RULES FOR SAFE INSTALLATION AND OPEIL_TION

1.Read the Owner's Manual for Safe Operation carefidly. Failure to tbllow tile rules tbr sale operation and the instructions can cause a malflmction of the boiler and resuh in death, serious bodily injury, and/or property damage.

2.Check your local codes and utility requirements before installation. The installation nmst be in accordance with their directives, or follow NFPA 31 - Installation of Oil Burning Eqnipment, latest revision.

3.Before serTicing, allow boiler to cool. Always shut offany electricity and oil to boiler when working on it.

4.Inspect oil line and connections for leaks.

5.Be certain oil burner nozzle is the size required. Overfiring will result in early failure of the boiler sections. This will cause dangerous operation.

6.Never vent this boiler into an enclosed space. Always vent to the outside. Never vent to another room or inside a building.

7.Be sure there is adequate air supply for complete combustion.

8.Follow a regular service and maintenance schedule for efficient and safe operation.

9.Keep boiler area clean and free of combustible material, gasoline and other flammable vapors and liquids.

10.Oil burners are not do-it yourself items. This boiler must be installed and serviced by qualified professionals using combustion test instruments.

11.Be aware when piping the relief valve that if the system pressure exceeds the safe limit of 30 pounds per square inch, the relief valve will automatically lift open. Lifting of the relief valve can discharge large

quantities of steam and hot water, which may damage the surroundings. Before installing the relief valve

read the manufacturer's instructions and maintenance section of the manual on relief valves.

12.Installation and sizing of the expansion tank must consider the heating systems total water volume,

temperature, boiler initial fill pressure, and system arrangement. An improperly installed and sized expansion tank may result in frequent lifting of the relief valve or other heating system problems. For proper installation, sizing, and maintenance of the expansion tank follow the guidelines established by Dunkirk Radiator Corporation and the expansion tank manufacturer.

13.Expansion tank performance and life expectancy can be hindered by overfilling the boiler. Dunkirk Radiator Corporation recommends an initial fill pressure of 10-12 psig. For higher fill pressures the expansion tank's air charge will need to be increased to match the fill pressure. Consult the manufacturer's guidelines for sizing and selection.

14.Purging the heating system of air and gases when first putting the boiler's into service is critical for proper

circulation and quiet performance. Once the air and gases are purged, for boiler installations using float type vents, the air vents should be closed for normal operation. If air is heard or noticed by a loss of heat, purge the system and open the vents for a short period of time.
