XI Start-up and Checkout

Use the following procedure for initial start-up of the boiler:

1) Ensure that the boiler is lled to the normal water level.

2) Verify that the vent system is complete and free of obstructions prior to start-up of the boiler.

3) Inspect all wiring for loose or uninsulated connections, proper size fuses installed, etc.

4) Verify that oil tank is lled with #2 fuel oil meeting ASTM D396 specications, oil piping has been tested and is air tight,

and shut-off valve(s) are closed.

5) Check initial settings of oil burner air band and air shutter, head setting etc. and readjust if needed. See Table 3 for setup

and combustion data pertaining to a particular boiler/ burner combination.

6) Attach plastic hose to oil pump vent tting and provide a container to catch oil during oil pump bleeding procedure.

7) Install 0-200 PSI pressure gauge into oil pump gauge port.

8) Open all oil line shut-off valves.

9) Open ame observation port cover on burner swing door to see ame.

10) Adjust system thermostat to highest setting.

11) Set pressure limit control to suit individual requirements of the installation. For most steam systems, the cut-in pressure

should be set at 0.5 psi with a 1 psi differential.

12) Turn the line service switch to “ON” position.

13) Crack open vent tting on the oil pump and allow burner to run until a solid oil stream, free of air bubbles, ows for 15

seconds into container. As the vent tting is closed, the burner should re and ame should be visible through observation

port immediately (or after prepurge timing has expired, if a burner is so equipped). Refer to burner instructions for more

details.

14) Immediately upon ring the boiler, check the smoke level. If the smoke level is in excess of a #1, open the air adjustment

to bring the smoke level below a #1.

15) Make sure that the oil pressure matches that shown in Table 3 for the burner supplied. Adjust pressure if required.

16) Check the vacuum at the inlet of the fuel pump. Make sure that the vacuum does not exceed the fuel pump manufacturer’s

limit (consult the pump manufacturer’s instructions).

17) Close the ame observation cover.

18) After chimney has warmed-up to operating temperature, adjust barometric draft regulator for a draft of -0.02 inch w. c.

over the re.

19) Check the CO2 and conrm that it is between the minimum and maximum limits shown in Table 3. Adjust if necessary.

20) Verify that the smoke level still does not exceed #1 and that the draft over re is -0.02 inch w.c.

21) Turn off the burner and remove pressure gauge. Install and tighten gauge port plug, than restart the burner.
