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.
If a fi re does occur, extinguish using
CO2 foam or dry chemical. Do not use
water.

CAUTION
Proper selection of thermal fl uid is
critical to system performance.
5. Determine multiple skid systems wiring requirements (between the skids).
Fulton will run conduit and wire the devices on each skid. For the devices
that have to come down for shipping, the wire will be left at the end Locate
electrical schematic diagram, a copy of which is inside of the panel box.
Ensure the information on the electrical drawing corresponds to your
voltage and frequency. Check the supply voltage and make sure that there
is no over-or under-voltage exceeding 10% of the nominal value.
NOTE:

Normal supply will be 460 volts, 3 phase, 60 Hz, AC unless otherwise
specifi ed.
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 650°F (345°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
the system. This is especially important during commissioning, when any
air trapped in the system is vented at high points, and when water, which
will fl ash into steam, is either expelled from the deaerator vent or drained
off at low points.
 Selecting a Thermal Fluid
The selection of the thermal fl uid most suited to your application is very
important. Factors to be considered include effi
ciency, thermal stability,
adaptability to various systems, and physical properties, including vapor
pressure, freezing point, and fl ash and fi re points.
Heat transfer fl uids of both mineral and synthetic origin have been specially
developed to give thermal stability over a very wide range of temperature. A
wide variety of thermal fl uids have been used successfully in Fulton Thermal
Fluid Heater systems, however, your fi nal selection should be made in
conjunction with recommendations from Fulton Thermal Corporation or the fl uid
manufacturer.
