Weil-McLain 550-141-829/1201 - Manual (Page 25)

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.
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.
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.
