Section 4 – Maintenance
Minimum equipment necessary to start and maintain fuel-fired thermal fluid heaters:
Digital
Multimeter
1. Required Maintenance at First Shutdown
a) The thermal fluid system should be shut down after no more than 24 hours of operation
at operating temperature. At this time, the following maintenance items will need to be
completed to meet the condition of warranty.
b) While pump is still at operating temperature, align circulating pump(s) to pump
manufacturer specifications. This should be done by means of a dial indicator.
c) 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 150°F are
acceptable to perform operation with regular work gloves.
d) With piping system at ambient temperature, torque all bolts on skid and throughout
system to gasket manufacturer specification using proper flange torquing practices
(incremental torque increases, star-pattern, etc). These values are available in the
installation section of the manual..
e) Visually inspect all thread fittings and valve packings. Repair leaks and tighten valve
packings to the point of stopping leak.
f) Upon putting unit back in operation, check all gauge readings and compare to values
given to you by the start up technician. Note any discrepancies and contact
manufacturer.
2. General Maintenance Schedule
Daily
a) Complete the log sheet attached at the end of this section at least once per day as a
minimum. It is recommended that the log sheet be filled out twice per shift of operation.
The log sheet is available from the Fulton Service Department or
www.fulton.com
b) Make visual inspection of the entire system for leaks. Make repairs as soon as possible.
c) In systems utilizing a water cooled thermal fluid circulating pump, check level of
lubricating oil in self-leveling reservoir and check cooling water circulation loop for proper
operation.
