INSTALLATION
!
WARNING
Do not use matches, candles, flame or
other sources of ignition to check for gas
leaks.
!
WARNING
The vent line connection on the gas
pressure regulator must be piped to
outdoor air by the installer in accordance
with National Fuel Gas Code, ANSI Z223-
1-1991 or latest addenda. In Canada, gas
installations must be in accordance with
the current CAN/CGA B149.1 and 2 and/or
local codes.

CAUTION
Some soap used for leak testing is corrosive
to certain types of metals. Clean all piping
thoroughly after completing the leak check.
!
WARNING
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
equipment.

When installed in a 575/3/60 service, the maximum supply voltage applied
to the boiler terminals is 600 volts and must always be met.
Full Load Amps (FLA) is the measured amperage for the boiler at its maximum
operating condition at rated voltage. The type of breaker/fusing selected, in
combination with the FLA, will affect proper circuit sizing/protection. Please refer
to your state's adoption of NEC or the authority having jurisdiction for proper
sizing/selection. Refer to Table 3 for FLA requirements.
Adhere to the following when making electrical connections:
1. Install wiring in accordance with NEC Sec. 110.3(B) or CSA C22.1 for Canada
for a maximum recommended branch circuit voltage drop of 3% and a
maximum total voltage drop for a combination of both branch circuit and
feeder not to exceed 5%.
2. Install wiring and ground in boiler in accordance with authority having
jurisdiction or in absence of such requirements National Electrical Code,
ANSI/NFPA 70.
3. Connect power to the boiler using connectors rated for the minimum in
Table 3, and are compliant with local electrical codes.
4. Provide separate power supplies for external devices. Do not power
external devices through the boiler.
5. Locate schematic. Each boiler is shipped with the electrical schematic
diagram, a copy of which is located in an envelope on the inside of the
panel box door.
6. A wall-mounted, fused disconnect sized for the unit must be provided and
fitted by the client/contractor if disconnect is not supplied on the panel.
7. Fuses must be sized according to motor name plates and local electrical codes.
8. Connect power to the terminal strip as supplied on the inside of the panel box.
–
NOTE: Single skid systems are generally shipped completely pre-wired.
9. Multiple skid systems may require wiring between the skids. Please note
that Fulton will run conduit and wire the devices on each skid. For devices
that are disconnected for shipping, the wire will be left at the end of the
conduit where possible and wired in the field (by others). When the system
has multiple skids that are adjoining, the conduit will be installed to break
at the skid joints. The wire for the conduit running between the skids will
be shipped loose to prevent damage when the skids are put back together.
These wires will need to be run by the installing contractor in the field and
wired to proper locations. If there is wiring between skids that are not
adjoining, then this will need to be done by others.
10. If the unit is not skid-mounted at the factory, the client/contractor is
required to wire the feed water pump starter.
–
NOTE: If the pump motor is not supplied by Fulton, the motor starter may not be
supplied.
