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.
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.
