Procedure for First Shutdown

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.

1. While pump is still at operating temperature, align circulating pump(s) to

pump manufacturer’s speci cations. This should be done by means of a

dial indicator.

2. 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 (65.5°C) are acceptable to perform

operation with regular work gloves.

3. With piping system cooled to ambient temperature, torque all bolts on

skid and throughout system to gasket manufacturer’s speci cations using

proper  ange torquing practices such as incremental torque increases, star

pattern, etc. Refer to torque speci cations in Tables 4 - 7.

4. Visually inspect all thread  ttings and valve packings. Repair leaks and

tighten valve packings to the point of stopping leak.

5. Upon putting unit back into operation, check all gauge readings. Note any

discrepancies and contact Fulton.

Daily Start-Up

1. Check positioning of all system valves to ensure  ow is not dead-headed.

2. Visually check relative position of minimum level  oat switch in the

combination tank.

3. Turn on power supply switches.

4. Where applicable, open water cooling valve and check that water  ows

correctly. (For water cooled pumps only.)

5. Set three position switch to “Pump”. Push and hold manual pump start

button, monitoring pressure gauges on heater.

6. When ready to begin heating, move three position switch from “Pump” to

“Heat”. After a short delay resulting from the purge period, the burner will

ignite. Make sure that the temperature setpoint is as desired.

7. On gas units, pilot valve activation will be indicated after pre-purge cycle
