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.
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.
No shutoff of any kind may be
placed between the safety relief
valve and the equipment, or in the
discharge pipe between such valve
and the atmosphere. Doing so may
cause accidental explosion from
overpressure.
Discharge from safety relief valve
must be confi gured so that there
is no danger of scalding personnel
or causing equipment damage.
Provisions must be made to properly
drain safety relief valve discharge
piping.
Failure to insulate ducting
on equipment with Flue Gas
Recirculation on the burner may
result in personnel injury.
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.
5. For heaters equipped with fl ue gas recirculation (FGR) on the burner, the
ducting must be insulated to prevent personnel injury.
System Interfaces
Proper selection and installation of the components in the hot oil system will
ensure proper and safe operation of the heater.
 Heater Connections
Adhere to the following for heater connections:
1. Connect the outlet of the pump directly to the inlet of the heater via
an isolating valve (preferably a throttling valve) and pump fl exible
connector.
2. Pipe heater outlets directly to the system via an isolating valve.
3. A safety relief valve may be shipped in the parts box accompanying the
fuel-fi red heater, and must be installed in the outlet manifold. On all units,
the outlet must be piped to a safe discharge area. The piping from the
outlet of the safety valve must be piped to a catch tank. The discharge
fl ow must not be restricted, i.e. no valve should be installed. The weight of
the piping must be properly supported in order to prevent damage to the
safety valve. If the valve body becomes warped, leakage may result.
