connected to the common venting system are not in
operation, the following steps should be followed with each
appliance remaining connected to the common venting
system placed in operation:
1. Seal any unused openings in the common venting
system.
2. Visually inspect the venting system for proper size
and horizontal pitch and determine that there is no
blockage or restriction, leakage, corrosion or other
defi ciency, which could cause an unsafe condition.
3. As far as is practical, close all building doors and
windows and all doors between the space in which
the appliances remaining connected to the common
venting system are located and other spaces of the
building. Turn on clothes dryers and any appliances
not connected to the common venting system. Turn on
any exhaust fans, such as range hoods and bathroom
exhausts, so they will operate at maximum speed. Do
not operate a summer exhaust fan. Close fi replace
dampers.
4. Place the appliance being inspected in operation.
Follow the lighting instructions. Adjust the thermostat
so that the appliance will operate continuously.
5. Test for spillage at the draft hood relief opening after
5 minutes of main burner operation. Do not use the
fl ame of a match or candle or smoke from a cigarette,
cigar or pipe.
6. After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, fi replace dampers and
any other gas-burning appliance to their previous
conditions of use.
7. Any improper operation of the common venting system
should be corrected so the installation conforms with
the National Fuel Gas Code, ANSI Z223.1. When resizing
any portion of the common venting system, the
common vent system should be resized to approach
the minimum size as determined using the appropriate
tables.
Electrical Connections
Motors are designed to operate within the following limits at
the motor terminals:
 AC power supplied is within +/- 10% of the motor
rated voltage with the rated frequency applied; or AC
power supplied is within +/- 5% of the rated frequency
and with the rated voltage; or a combined variation
in voltage and frequency of +/-10% (sum of absolute
values) of rated values provided the frequency variation
does not exceed +/-5% of rated frequency.
 For 3-phase motors, the line to line full voltage must be
balanced within 1% of the rated motor voltage. If the
motor is rated 360-440V, the voltage deviations must
be calculated from 400V. Operation outside these limits
will degrade motor performance. If the motor is rated
208-230V, the voltage deviations must be calculated
from 230V. Operation outside these limits will degrade
motor performance. 575V rated motors cannot be
operated at voltages above 600V.
 Depending on motor manufacturer, a 208V rated motor
may not be able to run below the design voltage.
Adhere to the following when making electrical connections:
1. Install wiring and ground in boiler in accordance with
authority having jurisdiction or in absence of such
requirements National Electrical Code, ANSI/NFPA 70.
NOTE:  Connect a ground wire to green colored ground
lug in electrical control box.
2. Review the electrical schematic diagram. Vantage
boilers are available with a variety of 3 phase electrical
confi gurations. Step-down transformers are provided as
standard with every boiler. Each boiler is shipped with
its own unique electrical schematic diagram, a copy of
which is located in an envelope on the inside door of
the panel box.
3. Connect power to the terminal strip as supplied on the
inside of the panel box.
Assembly of Fulton Multi-Skid Systems
Adhere to the following for multi-skid engineered systems:
1. Refer to the Fulton mechanical/electrical drawings
during assembly.
2. Ensure that equipment orientation allows for operation
interface and maintenance.
3. Align the skids as shown on the drawings ensuring that
skid fasteners (skid joint angles) are matched. The skid
joint angles are a matched set and the edges of the
fasteners should be exactly aligned.
