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.
Do not attempt to start the
equipment for any testing prior
to fi lling and purging the vessel.
A dry fi re will seriously damage
the equipment and may result in
property damage or personnel injury
and is not covered by warranty. In
case of a dry fi ring event, shut off
the fuel supply and allow the vessel
to cool to room temperature before
fl uid is reintroduced to the pressure
vessel.
Failure to insulate ducting
on equipment with Flue Gas
Recirculation on the burner may
result in personnel injury.

CAUTION
Avoid fl ue corrosion and other negative
impacts ensuring properly-sized stack
and fl ue.
In order to meet warranty conditions,
ensure appropriate tests and
operational safety activities are
performed.
Unless specially fi ltered, compressed air
will introduce moisture to the system.
Dry air or nitrogen is recommended.
7. Connect the conduit runs between the skids and tighten conduit
connectors.
8. Locate the supplied wiring for the equipment and pull wiring through
the appropriate conduit runs. Electrical wires are labeled for easy landing.
Connect all wiring per the Fulton supplied electrical drawings.
9. If a header is supplied, mount the header as shown in the mechanical
drawing.
NOTE:

For piping supplied in sections, make up and connect hand tight until all
sections are in place to ensure sections align properly. Sections are match marked
for reassembly.
10. Tighten all connections.
11. Pneumatically test the piping (at 15 psig maximum) prior to fi lling the
systems.
12. Check bolts and connections for tightness after the fi rst heat up cycle.
Retorquing may be required.
Stack and Flue
An appropriately sized stack should be connected to the fl ue gas outlet at the
heater. The proper fl ue size and draft control is most important for proper burner
operation. The fl ue must be as large or larger than the outlet on the vessel.
Avoid fl ue piping and elbows by placing the equipment as close as possible to
the chimney.
Adhere to the following for stack and fl ue installation (see Figure 18):
1. Ensure the stack is the same diameter as the fl ue gas outlet for an FT-
0080C, and at least one size larger for the coil design models FT-0120C and
larger.
2. Ensure the stack rises continuously to the connection at the chimney and
contains no more than two bends at 45 degree angles or less. If required,
as a result of space limitations, one 90 degree elbow (or tee) can be fi tted
at the back of the vessel.
3. Ensure 2 feet (0.6 m) of straight, horizontal fl ue before any change in
direction, fi tting or draft regulator. This is to prevent potential pilot or
main fl ame failures due to back pressure build up during ignition. Any
alternative stack arrangement must supply negative 0.02 to 0.04”wc.
4. Ensure the run in the total distance of stack ducting, as measured in a
straight line from the outlet of the heater to the outlet of the stack, does
not exceed 70% of the rise. With the exception of the duct run previously
described, horizontal sections of ducting must be avoided and should not
exceed 4 feet (1.2 m) total. See Figure 18.
5. Ensure the stack, chimney, and any components associated with the stack,
such as heat reclaimers or assist fans, are constructed from material that is
