Start-Up

Start-Up

Follow information below to prevent severe personal injury, death or

substantial property damage:

Do not use gasoline crankcase drainings or any oil containing gasoline. See burner manual for proper fuel oil.

Do not attempt to start burner when excess oil has accumulated, when unit is full of vapor or when combustion chamber is very hot.

Do not start burner unless collector hood, flue cap, jacket cap, breeching and burner mounting door are secured in place.

Never burn garbage or paper in the boiler.

Never leave combustible material around it.

Fill the system:

1.Do not fill (except for leakage tests) until boiler is ready to be fired.

2.Fill to normal water line as indicated on jacket front panel.

3.Boiler water pH 7.0 to 8.5 is recommended.

Failure to maintain recommended pH level can

cause section failure and leaks.

4.Follow "Skim steam boiler" to assure proper operation.

Tips for steam systems:

Check boiler and system piping for leaks. Continual makeup water will reduce boiler life. Minerals can build up in sections, reducing heat transfer and causing cast iron to overheat, resulting in section failure.

Failure to maintain recommended pH and repair

leaks can cause section iron corrosion, leading to section failure and leaks. Do not use petroleum-based sealing or stop-leak compounds in boiler system. Damage to system components can result.

For pH conditions outside 7.0 to 8.5 range or unusually hard water areas (above 7 grains hardness), consult local water treatment company.

Do not use petroleum-based compounds in boiler system.

Damage to system components can result, causing property damage.

1.Provide 1½" skim piping from skim tapping to floor drain. Add a tee in piping to observe skim water level. Raise waterline to midpoint of skim tapping.

2.Fire burner to maintain water temperature below steaming temperature during skimming process.

3.Feed in water to maintain water level. Cycle burner to prevent rise in steam pressure. Continue skimming until discharge is clear.

4.While boiler is warm, but not hot, drain boiler through drain valve.

5.Remove skim piping. Close drain valve. Fill with fresh water to normal waterline. Start burner and steam for 15 minutes to remove dissolved gases. Stop burner.

6.Check traps and air vents for proper operation.

7.Process may need to be repeated after several weeks of operation.

To place in operation:

1.Verify boiler is filled with water to normal waterline as indicated on jacket front panel.

2.Open burner door and verify rear target wall, floor and burner door insulations are in proper position and condition.

3.Verify burner mounting door is closed tightly and burner wiring harness is connected to junction box.

4.Factory burner adjustment and settings may not be suitable for specific job conditions. See Appendix, page 27.

Make final burner adjustments using combustion test equipment

to assure proper operation. Do not fire boiler without water. Sections will overheat, damaging boiler and resulting in substantial property damage.

5.Check boiler and system piping for leaks. See “Tips for steam systems.”

6.Inspect breeching and venting for proper operation.

Skim steam boiler:

Clean new steam boilers to remove any impurities. Failure to properly clean can result in violent water level fluctuations,

water passing into steam mains, or high maintenance costs on strainers, traps or vents. Skim boiler only. Do not clean old piping or leaks can occur.
