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
reference purposes only. No Fulton
document may substitute for full
review of documentation available
from the component manufacturer.
To maintain a reasonable
temperature in the equipment area
and ensure safety to personnel, the
section of the chimney duct within
the building should be insulated.
Due to extremely high operating
temperatures of the thermal fl uid,
all exposed pipework should be
insulated, and exposed hot fl anges,
pump, valve, and fi ttings should be
shielded. Refer to Insulation section of
this manual for details.

Insulation
After the appropriate system tests have been satisfactorily completed (see
Testing section of this manual), all hot pipework and vessels must be adequately
insulated with material suited to the temperature and application to prevent
both heat loss and personnel injury.
Adhere to the following for insulation installation:
1. For inspection and maintenance purposes, leave pumps, fl anges, valves
and fi ttings uninsulated but suitably shielded for safety.
2. Insulate the deaerator section of the combination tank.
3. Do not insulate the thermal buff er and expansion sections of the
combination tank. On units operated with inert gas blankets above the
fl uid in the expansion tank, the entire combination tank, including the
expansion and thermal buff er sections, may be insulated but it is not
necessary.
4. Ensure hot oil pipe insulation is a minimum of 2” (51 mm) thick,
high temperature, laminated, foamglass cellular glass insulation as
manufactured by Pittsburgh Corning Corporation or equal.
System Interfaces
Proper selection and installation of the components in the hot oil system will
ensure proper and safe operation of the heater.
