NOTE: If the unit is not skid-mounted at the factory, the client/contractor is
required to wire the circulating / feed water pump starter.
NOTE: If the circulating pump motor is not supplied by Fulton, the motor starter
will not be supplied.
6. Locate electrical schematic diagram, a copy of which is inside of the panel
box.
7. Ensure the information on the electrical drawing corresponds to your
voltage and frequency.
8. Adhere to the following:
Typical 120 VAC controls allow for a +10% and -15% voltage fl uctuation.
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 load voltage must be balanced
within 1% of the rated motor voltage. If the motor is rated 208-230V, the
voltage deviations must be calculated from 230V. Operation outside of
these limits will degrade motor performance. 575V rated motors cannot be
operated at voltages above 600V. Depending on the motor manufacturer,
a 208V rated motor may not be able to run below the design voltage.
Thermal Fluids
Thermal Fluids at Elevated Temperatures
Personnel must be familiar with the nature of potential hazards when working
with thermal fl uids at operating temperatures. Unlike steam or high-pressure
water systems, thermal fl uid attains extremely high temperatures without a
corresponding increase in pressure.
Adhere to the following:
1. Be aware that certain types of thermal fl uid may have operating
temperatures reaching 600 F (316 C) and above, so all exposed pipework is
hazardous and should be insulated.
2. Check that fl anged joints are tight during and after the fi rst warming up of
the system. Turn Burner and pump off before fi ttings are tightened. After
these checks, exposed hot fl anges, pumps, valves and fi ttings should be
fi tted with some sort of shield.
3. Remember that there is pressure generated in the system by the circulating
pump. Care should be exercised when opening any drain or vent valves in
!
WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct, and strict
adherence to applicable jurisdictional/
professional codes and regulations.
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.
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
equipment.
