4) Note feedwater deaerator pressure gage and thermometer readings and verify gage and thermometer accuracy. Inspect safety valve installation and verify that the valves have proper set pressure and capacity and are properly installed. Perform an operation test under pressure to confirm operation at proper
5) set pressures. Verify that the deaerator can safety withstand the test pressure prior to testing the valve(s) in-situ.
6) Verify that non-condensable gas vent line is open and proper orifice is provided to permit venting of gases.
7) Inspect support structures for proper integrity and allowance for thermal expansion.
8) Internal inspections (annual cleaning and inspection and wet magnetic particle intervals unless otherwise recommended because of welding repairs):
i. Visually inspect all visible pressure vessel surfaces for corrosion, material thinning, deposits, and weld cracking.
ii. Inspect spray nozzles and trays.
iii. Certified American Society for Non-Destructive Testing (ASNT) Level II technicians shall perform non-destructive tests using the wet fluorescent magnetic particle (WFMT), ultrasonic testing (UT), and any other necessary non-destructive tests.
1. Completely examine all accessible welds utilizing the WFMT test method. Properly prepare the surfaces before testing.
2. Determine pressure vessel material thickness by UT. Thickness measurement locations shall be selected by dividing the storage tank heads into quadrants and taking measurements at each quadrant on two imaginary rings in each head (eight measurements total). Measurement locations on the shell shall be on each of the quadrants, on four to six locations along the length of the shell (16 to 24 measurements total). The technician may recommend fewer or more tests to the owner, providing justification.
3. Typically, the pressure vessel section containing the deaerator trays and sprays is not accessible for nondestructive testing. The experience is that this section, which is mainly exposed to steam, is less vulnerable to weld failures and material thinning than the storage section which contains condensate and make-up water.
iv. Calculate maximum allowable working pressure rating of vessel based on thickness measurements. Calculate depletion rate of material thickness.

· SAMPLE DOCUMENT SUBMISSION
| Description: |
| Condensate Storage Tank High Water Alarm |
| Purpose: |
| High water level may be an indication of condensate transfer pump failure that could lead to low water condition in the feedwater deaerator and in the boilers. There may be a failure of make-up water controls. |
| Recommended set point: |
| 4 inches below overflow level and 2/3 of tank height. |
| Potential hazards due to failure of high-water alarm: |
| Feedwater deaerator running dry and, consequently, boiler feed pumps running dry will cause over healing and damage to pumps and potential for plant shutdown. Failure of make-up water controls (in open position) could lead to significant cost from waste of water and condensate from the tank overflow if this occurs over long time period. |
| Recommend type of device: |
| Conductivity probe type switch. Float type switches have high failure rate in this application where they are exposed to flash steam that causes seals to harden and prevent float movement. |
| VA Master Specification section: |
| 23 50 11 |
| VA Standard Detail: |
| S D232 11l-05. |
| Failure rate of float types: |
| 48% |
Make and Model:
| Did it function properly: |
| Yes/No |
| Category & Action Time Limit: |
| Upon Failure or within 5 years |
| Comments: |
| Float type switches are not allowed for high water alarms |
P.S: The VA recommended switch type is a conductivity probe type switch. Install the VA recommended switch and set alarm at 2/3 of the tank height. There are valves that can isolate this alarm. These valves must be made lockable only in the operating position.

ADDITIONAL SAFETY DEVICE TEST PROCEDURES FOR HOT WATER BOILERS
Appendix B.1 INTRODUCTION
Appendix B presents step by step test procedures for safety devices that are specific to hot water boilers. The appendix provides forms for obtaining and recording all necessary data for each safety device being tested. This Appendix is a supplement to Appendix A to be used in testing a hot water boiler.
The assumptions for the test procedures given in this Appendix are first listed. This information is then followed by one sheet for each device being tested to be used by the testing agency personnel as a check list and data form. These procedures must be made site specific to be in compliance with VA requirements. It is very important that all data required in these procedures are taken each time a test is made. Forms that contain pre-filled data lead to mistakes. Also, it is important not to use a “check list form” because a reviewer cannot verify that the test has been done correctly due to absence of data.
Appendix B.2. ASSUMPTIONS FOR TEST PROCEDURE
The test procedures in Appendix B makes certain assumptions that are listed below.
PLEASE NOTE THAT THESE ITEMS ARE NOT ALWAYS REPEATED IN EACH TEST PROCEDURE BUT APPLY TO ALL TESTS.
· After each test, equipment should be returned to normal operating condition and the boiler should be fired to confirm its operability.
· “Jumping” means disabling the switch electrically.
· Any electric “jumper” application requires that all power to the device being “jumped” be shut off and only personnel that are trained and qualified to the correct level by NFPA 70E perform such tests.
· Pressure gages used in a test must be calibrated within prior 6 months.
· The set point is the value at which the safety device indicator is set. The trip point is the actual value at which the safety device activates. Some language used in the test procedures assumes that the set point equals the trip point.
Checklist for Low Water Cutout Hot Water (LWCOHW)
| Item |
| Manufacturer |
| Probe Y/N |
| Sight Glass in External Water Column (Y/N) |
LWCOHW
* If factory setup has a water column containing a low water cutoff device and/or has points to install a sight glass, a sight glass must be installed. If factory setup is testable and utilized, then the LWCOHW device must shut the boiler down and lock out through the BMS at a water level visible in the sight glass and above the manufacturer designated minimum water level. One external probe water level cutout is required (LWCOHW) if there is no sight glass and method to test the factory unit provided by the manufacturer by draining the boiler water to verify activation. The external LWCOHW setup is shown below. The LWCOHW setup must be mounted in an accessible location in the hot water return line above the boiler and downstream (boiler side) of any isolation valve. It must contain a conductivity probe, a visible water level indicator, lockable only open isolation valves, a lock closed drain, and lock closed vent as shown below. This external setup will be independent of any factory installed low water device and must utilize a conductivity probe setup that upon activation must disconnect power to the boiler and require manual reset of relay to reenergize and operate boiler. The probe set point should activate and shutdown power to boiler with water level visible in the sight glass provided the bottom of the sight glass is higher than the min water level for the boiler.
· If using factory unit refer to manufacturer provided procedure for proper test method. (Simply using factory test circuit button is inadequate).
· If using external unit, locate external LWCOHW water column in HW return piping.
Checklist for Low Water Cutouts (LWCOHW) (Continued)
· Remove locks and close external water column isolation valves to isolate water column.
· Slowly open column vent valve to allow column to be drained. (HOT WATER, USE APPOPRIATE PPE !!!!)
· With boiler online, slowly open column drain valve and slowly drain water column until LWCOHW activates. Close drain.
· Upon activation record the water level in the sight glass at which the probe activates.
· Verify the boiler shuts off and has no power by verifying control panel is dead. (Use multimeter if no power light indication)
· Slowly and slightly open bottom isolation valve to fill water column until water flows out of vent. Once water flows from vent, close vent, and open top isolation valve.
· Replace locks on isolation valves. Reset LWCOHW relay and return to normal operation.
| Result |
| Y/N |
| Water Level |
Correct installation?
Did the LWCOHW work correctly? Record Level.
Did the LWCOHW shut down and lockout boiler if using factory setup or shutoff power to boiler and require manual reset if using external setup?
Was water level visible in sight glass and more than 1 inch above bottom of sight glass at activation point?
Did the device fail or pass the 3 Question Criteria (section 1.3.1)? Pass Fail If boiler is to be operated with failed safety device, a properly approved ISM is required. Describe safety device failure/remedy in Appendix H.
