Pennco 3KW0.60 - Manual (Page 5)

5
1. Failure to follow rules for safe operation and
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. 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. Shut off any
electricity and oil to boiler when working on it.
4. Inspect oil line and connections for leaks.
5. Verify oil burner nozzle is the size required. Over-firing
will result in early failure of 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. Verify there is adequate air supply for complete
combustion.
8. Follow regular service and maintenance schedule for
efficient, safe and reliable 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. Boiler must be
installed and serviced by qualified professionals using
combustion test instruments.
DO NOT USE GASOLINE CRANKCASE DRAININGS
OR ANY OIL CONTAINING GASOLINE.
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 safety relief valve if system
pressure exceeds safe limit of 30 pounds per square
inch, safety relief valve will automatically lift open.
Lifting of safety relief valve can discharge large
quantities of steam and hot water, which may damage
surroundings. Before installing safety relief valve read
manufacturer’s instructions and maintenance section of
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 safety relief
valve or other heating system problems. For proper
installation, sizing, and maintenance of expansion tank
follow guidelines established by boiler manufacturer
and expansion tank manufacturer.
13. Expansion tank performance and life expectancy can be
hindered by overfilling the boiler. Boiler manufacturer
recommends 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 heating system of air and gases when
first placing 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.
