Unpacking and inspection Upon receipt of the Boiler Drum Level instruments, examine the contents of the container(s) for damage. Report any faulty conditions as soon as possible to your carrier to avoid acceptance of damaged goods. Clark-Reliance will not be responsible for goods damaged in shipping or storage, or subsequent loss or damage due to improper storage or exposure as a result of damage to shipping containers.
Boil-out Gage Practice and Policy On new boiler installations, it is common procedure to initially operate the boiler at a reduced pressure for a short time to ‘cook out’ foreign materials (pipe joint compound, grease, oil, flux, etc.) that remain in the drum or other pressurized parts of the system after the boiler has been constructed. During this boil-out period, most of the suspended or dissolved debris is flushed out with blow-down discharges.
Recommended Blow-Down Procedure for Water Columns and Gage Glasses The importance of proper cleaning and maintenance of the water column and the water gage glass, or sight glass, cannot be stressed enough. The water column must he kept clean to ensure the water level in the gage glass accurately represents the water level in the boiler. Note that the frequency and method of blow-down may affect service life and performance of the water column and gage glass.
3. Always notify control room personnel prior to conducting a Blo w-Down to prevent any false alarms or false trips. Recommended Maintenance and Annual Inspections Regarding any recommended maintenance procedures or annual inspections, we suggest any device containing probes should be inspected on an annual basis for contaminated probes and wire secure terminations. Caution: Before proceeding, follow any and all plant lock out - tag out procedures required.
Prismatic and Flat Glass Gages BEFORE YOU INSTALL THE GAGE GLASS: - Support brackets should be considered for gages over four feet long and weighing in excess of 100 pounds. The support brackets will help prevent overloading of the connecting valves and piping. The brackets will also help prevent damage caused by excessive vibration.
Disassembly: -After pressure is relieved from the gage glass, remove from the boiler drum and lay flat on a workbench -Loosen end bolting first, working from the opposite ends toward the center of the gage. -Remove all components including washers, finger clamps, cover plates, gaskets, glass, and Mica shields. Retain the bolting and cover plates. Discard all gaskets, glass, and Mica.
Recommendations and Instructions for Hot Torquing Gage Glasses and Probe Type Devices When a new piece of equipment, whether a Gage Glass or a Probe* type device is installed, the hot torque procedure must be performed. This ensures that all bolting and components are properly seated for optimum performance. This procedure must also be performed after any maintenance is done to the equipment.
Installation Instructions for Model GL-53 Water Gage Illuminators for Tubular Glass Gages or Prismatic Gages 1.
