Required Equipment
The following minimum equipment is necessary to start and maintain fuel-fi red
thermal fl uid heaters:
 Digital Multimeter
 Combustion Analysis Equipment
 Draft Gauge
Required Maintenance at First Shutdown
The thermal fl uid 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.
1. While pump is still at operating temperature, align circulating pump(s) to
pump manufacturer specifi cations. This should be done by means of a dial
indicator.

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 (65.5 C) are acceptable to perform
operation with regular work gloves.
3. With piping system at ambient temperature, torque all bolts on skid and
throughout system to gasket manufacturer specifi cation using proper
fl ange torquing practices (incremental torque increases, star-pattern, etc).
These values are available in the installation section of the manual..
4. Visually inspect all thread fi ttings and valve packings. Repair leaks and
