1. Read the Owner’s Manual for Safe Operation. Failure
to follow rules for safe operation and instructions can
cause malfunction of boiler and result in death, serious
bodily injury, and/or property damage.
2. Check your local codes and utility requirements before
installation. 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. Over-
firing will result in early failure of the boiler sections.
This will cause dangerous operation.
6. Never vent this boiler into enclosed space. Always vent
to outside. Never vent to another room or inside a
building.
7. Be sure there is adequate air supply for complete
combustion.
8. Follow 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.
WARNING
Burn and scald hazard. Safety relief valve could
discharge steam or hot water during operation.
Install discharge piping per these instructions.
!
11. Be aware when piping the safety relief valve if system
pressure exceeds safe limit of 30 pounds per square
inch, the safety relief valve will automatically lift
open. Lifting of the safety relief valve can discharge
large quantities of steam and hot water, which may
damage the surroundings. Before installing the safety
relief valve read the manufacturer’s instructions and
maintenance section of the manual on safety relief
valves.
12. Installation and sizing of the expansion tank must
consider heating systems total water volume,
temperature, boiler initial fill pressure, and system
arrangement. Improperly installed and sized expansion
tank may result in frequent lifting of the safety
relief valve or other heating system problems. For
proper installation, sizing, and maintenance of the
expansion tank follow guidelines established by tank
manufacturer.
13. Expansion tank performance and life expectancy can
be hindered by overfilling the boiler. Recommend initial
fill pressure of 10-12 psig. For higher fill pressures
expansion tank’s air charge will need to be increased to
match fill pressure. Consult manufacturer’s guidelines
for sizing and selection.
14. Purging the heating system of air and gases when
first putting boiler into service is critical for proper
circulation and quiet performance. Once air and gases
are purged, for boiler installations using float type
vents, air vents should be closed for normal operation.
If air is heard or noticed by loss of heat, purge system
and open vents for short period of time.
