|
| The boiler is a natural gas fired 1,200,000 BTW/hr RBI LW1200 (as-built RBI drawing #42-2112).
| | Information about the boiler has moved to a [[Pool Boiler|separate page]]. |
| | |
| Interlocks prevent the boiler from operating when the water level is too low, sufficient water flow is not present or the air pressure differential (as generated by the blower motors) is insufficient. Redundant over-temperature lock-outs (including those added by FFSC maintenance) prevent operation in the event that the temperature rises beyond a threshold.

| ===Maintenance===
| |
| | |
| Regular inspections are mandated by the state and the insurance company. These inspections occur every three years. Prior to the official inspection, a '''Steam/Hot Water ASME CSD-1''' form must be completed by a qualified technician. This form contains details about the boiler (identified by the state license and serial numbers), identifying key controls, their set-points and operation test results. Any issues found during the technician's inspection must be remedied before the document becomes acceptable as proof of compliance per Rule 27 of the State of Michigan Boiler Code.
| |
| | |
| Two copies of the CSD-1 should be kept by FFSC. One placed in a room near the boiler, another in a central filing location.
| |
| | |
| ===Troubleshooting===
| |
| | |
| First, always ensure that the breaker and GFCI are not tripped, and that the power switch on the side of the unit is turned on.
| |
| | |
| If the boiler does not fire in response to a call for heat, the issue is likely related to an interlock or the ignition system. Verify that the low water sensor is reset; it can be tripped by air infiltration during filter back-washing. Ensure that the pump is operating. Verify that the covers are securely fastened; a loose cover leaks air and may not close the air pressure switches. Finally, check for the presence of spark and/or pilot light. This is visible via a small window on the lower-left of the unit.
| |
| | |
| The flame sensor unit is a consumable item and may need to be replaced at a regular interval (every two years?). If the pilot valve (PV) is open, but the main valve (MV) never opens, it is likely that adequate flame is not being detected. This can be verified by measuring the microamp current output of the flame sensor and should be done by a qualified technician.
