4. Strainers should be cleaned by means of compressed air. A rag will merely
force the smaller particles into the mesh of the strainer. It is recommended
to place a lint free rag in the center of the strainer and blow air from the
outside, trapping the debris in the rag.
5. Allow the pump to run again for several minutes and repeat the fi ltering
process until pump suction pressure remains steady after cleaning. The
amount of time which must be allotted for fi ltering varies with the system.
6. When the system is initially brought up to temperature, additional pipe
scale and welding slag will loosen and enter the fl uid stream. This will be
trapped in the strainer causing vacuum at the pump suction.
Boilout
1. Ensure adequate ventilation.
2. Check for correct fuel feed. All air must be eliminated from fuel lines, gas
piping, preheaters, etc. by approved methods.
NOTE: As the system is being boiled out, the piping must be checked
for leaks as the temperature of the thermal fl uid is increased. If a leak
is detected, refer to Thermal Fluids at Elevated Temperatures section in
Installation section of this manual.
3. Open all manual valves in the fuel oil supply line. Do not run the fuel pump
dry or without fuel lines connected to fuel source. Do not allow the fuel oil
pump to pull a vacuum.
4. Check safeties.
5. Disable N2 blanket if equipped and open vent line on DA tank.
6. Set control switch to “Heat”. The burner will begin the call for heat if oil
temperature is below setpoint.
7. With burner fi ring and pump running, keep checking the gauges
indicating pump and circuit pressures. Make sure they remain stable.
8. In case of pressure fl uctuations, stop the burner, but allow the pump to
continue to circulate fl uid.
9. When pressures have stabilized, start burner again.
10. Continue in this manner up to the maximum operating temperature.
Throughout the initial warm-up, the expansion tank and its overfl ow pipe
must be watched to detect the formation of steam, indicating the presence
of water. If this occurs, burner should be shut down.
11. If steam is forcing thermal fl uid out of the expansion tank vent, turn
the heater off , but leave the pump on. This is to circulate the hot fl uid
through the piping without fl ushing the steam too quickly. Once steam
and thermal fl uid stop leaving the expansion tank unit, the heater can
be turned on. Increase the temperature very slowly to prevent fl uid from
being forced out of the tank.

WARNING
Before commissioning the equipment,
verify with authorized personnel that the
gas lines have been purged.
Never attempt to operate a heater that
has failed to pass all the safety checks.
After checking controls by manual
adjustment, make sure they are always
reset to their proper settings. Contact
your Fulton dealer before modifying the
equipment.
If any “Manual Reset” limit device trips
DO NOT reset without determining and
correcting the cause. (Manual Reset Limits
may include: fl ame safeguard, high or low
gas pressure, high temperature limit, high
pressure limit)
WHAT TO DO IF YOU SMELL GAS :
Do not use matches, candles, fl ame or
other sources of ignition to check for gas
leaks. Do not try to light the appliance. Do
not touch any electrical switch; do not use
any phone in your building. Immediately
call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s
instructions. If you cannot reach your gas
supplier, call the fi re department.
If excessive amounts of thermal fl uid
are to be vented from the system,
additional thermal fl uid may be required
in the system. Contact Fulton for further
information.
Flash steam may be generated at any
point up to the operating temperature.
Watch for gauge fl uctuations.
If fl uid or piping is added to the system,
the boil out procedure is required, as water
may have been introduced to the system.
