RULES FOR SAFE INSTALLATION AND OPERATION
1. Read the Owner's Manual for Safe Operation carefully. Failure to follow the rules for
safe operation and the instructions can cause a malfunction of the boiler and result in death,
serious bodily injury, and/or property damage.
2. Check your local codes and utility requirements before installation. The installation must
be in accordance with their directives, or follow NFPA 31 - Installation of Oil Burning
Equipment, latest revision.
3. Before servicing, allow boiler to cool. Always shut off any 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 im-
properly 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 Boilers and the expansion
tank manufacturer.
13. Expansion tank performance and life expectancy can be hindered by overfilling the boiler.
Dunkirk Boilers 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 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.
WARNING
This boiler has been designed for residential installations. If used for commercial applications,
all jurisdictional requirements must be met. This may require wiring and/or piping
modifications. The manufacturer is not responsible for any changes to the original design.
