PROCEDURE FOR FIRST SHUTDOWN
1. The heater system should be shut down after no more than 24 hours of operation at full
operating temperature. At this time, the following maintenance items will need to be completed
to meet warranty conditions.
2. While pump is still at operating temperature, align circulating pump(s) to pump manufacturer’s
specifications. This should be done by means of a dial indicator.
3. Isolate Y-strainer(s) in system and clean regardless of pump suction pressure. Make sure that
the temperature is low enough to handle safely or provision has been made to handle materials
at high temperature. Generally, temperatures below 65°C are acceptable to perform operation
with regular work gloves.
4. With piping system cooled to ambient temperature, torque all bolts on skid and throughout
system to gasket manufacturer’s specifications using proper flange torquing practices such as
incremental torque increases, star pattern, etc. Refer to Section 2, Installation.
5. Visually inspect all thread fittings and valve packings. Repair leaks and tighten valve packings to
the point of stopping leak.
6. Upon putting unit back into operation, check all gauge readings and compare to values given to
you by the start-up technician. Note any discrepancies and contact Fulton Ltd.
11. If steam is forcing thermal fluid out of the expansion tank vent, turn the heater off, but leave
the pump on. This is to circulate the hot fluid through the piping without flushing the steam too
quickly. Once steam and thermal fluid stop leaving the expansion tank unit, the heater can be
turned on. Increase the temperature very slowly to prevent fluid from being forced out of the
tank.
12. Continue bringing unit up to temperature slowly, with a temperature rise not exceeding 100°F
(38°C) per hour. Do not exceed specified maximum outlet temperature. In the absence of
specific information, consult the factory before proceeding.
13. Once up to temperature, check the fluid level in the expansion section by opening the high
level manual test connection. If a permanent flow of fluid results when this valve is opened, and
if all previous precautions have been followed, the expansion tank is too small for the capacity
of the fluid in the installation. A larger tank must be installed.
14. After fifty hours of operation at operating temperature, check all flanges and connections for
tightness.
