4. Do not exceed the maximum pressure allowed at the
fuel oil pump inlet per the National Fire Protection
Association (NFPA).
NOTE:

If for some reason the pressure of the fuel supply will
exceed NFPA maximum, fi tting a regulator to the fuel line
must be considered, e.g. when there is a tank situated with an
oil level eight feet (2.4 m) or more above the pump.
5. On units fi tted with NFPA controls, ignition is obtained by
means of a gas pilot. A natural gas or LP supply is required
for these units. The required gas supply pressure is 7” w.c.
If a guaranteed supply of natural gas is not available, then
a supply of bottled gas at 11“w.c. is required. For details
contact a local liquid propane dealer.
Instrument Air
Instrument air provision for pneumatically actuated control
devices should meet the minimum and maximum fl ow rate
and delivery pressures specifi ed by the individual equipment.
Additionally, it should be a dry, dust free supply with a dew
point of -40°F (-40°C).
Electrical Supply
Adhere to the following for electrical supply installation:
1. Install wiring and ground in equipment in accordance
with authority having jurisdiction or in absence of such
requirements the National Electrical Code, ANSI/NFPA 70.
2. Provide a wall-mounted, fused disconnect sized for
the unit. This must be fi tted by the client/contractor if
disconnect is not supplied on the panel.
3. Size fuses according to motor name plates and local
electrical codes.
4. Connect power to the terminal strip as supplied on the
inside of the panel box.
NOTE:

Single skid systems are generally shipped completely
prewired.
NOTE:  The liquid level switch on the expansion tank, when
supplied, will be shipped in the parts box and must be
installed in the fi eld.
