Fill the system | Weil-McLain 550-141-830/1202 manual

Detailed Service Procedures

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 recom- mended pH can cause section failure and leaks.

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 maintenence costs on strainers, traps or vents. Skim boiler only. Do not clean old piping or leaks can occur.

Do not use petroleum-based

compounds in boiler system. Damage to

system components can result, causing property damage.

1.Provide 1-1/2" skim piping from skim tapping (located on front of boiler) 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 opera- tion.

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

To place in operation:

Follow information below to prevent severe personal injury, death or substantial prop- erty damage:

●Do not use 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 in combustion chamber, 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 mount- ing door are secured in place.

●Never burn garbage or paper in the boiler.

●Never leave combustible material around boiler.

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 condition and position.

3.Verify burner mounting door is closed and

bolted tightly and burner plug is connected.

4.Refer to burner manual for burner start-up, adjustment and check-out procedures. Factory burner adjustment and settings may not be suitable for specific job conditions.

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.

6.Inspect breeching and venting for proper operation.
