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.
Non-Fulton product information is for

review of documentation available
from the component manufacturer.
Failure to properly locate and
install vent connections may cause
personnel and property damage.
 SIZING EXAMPLE
A system contains 175 gallons, including the heater, but not the tank. You select
the FT-200-L, so you add 25 gallons to 175 for a total of 200 gallons.
You look up the expansion rate for the thermal fl uid. (Assuming it is 25%), 200
gal. x 1.25 = 250 gallons, 250-200 = 50 gallon expansion.
The FT-200-L has only 46 gallons available for expansion, so the correct selection
is the FT-500-L.
Adhere to the following for installation:
1. Install tank in accordance with Fulton Thermal Corporation’s specifi cations.
2. Unless the system is pressurized, the inlet to the deaerator section must be
higher than or equal to the highest point in the system to prevent pockets
of air from collecting in system piping.
3. Take into account the head required at the circulation pump suction inlet to
avoid the possibility of pump cavitation.
4. In systems operating close to maximum fl uid temperature, ensure the tank
is elevated enough, possibly well above the highest point in the system, to
prevent pump cavitation by increasing the static head. An inert pressurizing
blanket may be considered as an alternative. See Pressurized Systems
section of this manual.
5. Provide supports for tank mounting. These should be suited for supporting
the tank by the side rails. The eyelets fi tted to the tank are for lifting only.
 Pressurized Systems
Nitrogen pressurization may be used if the total system content is very large, or
in a system operating near or above the vapor pressure of the fl uid employed, or
if the inlet of the DA tank is not the highest point in the piping system, or at any
time to further protect the fl uid from oxidation.
In conjunction with this system, adhere to the following:
1. An automatic venting device must be fi tted to the system expansion tank.
Consult Fulton Thermal Corporation for further details.
2. The location for the liquid level switch (Figure 13) is a 2-1/2” NPT connection
on the same end of the tank as the inlet. The liquid level switch is supplied
and shipped with the unit, and must be installed by the customer and then
wired to the control panel.
3. If the tank is located outdoors, nitrogen is required.
