OIL-FIRED NATURAL DRAFT STEAM BOILER — SERIES 4 —
Start up
(continued)
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 op-
eration.
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 caus-
ing 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 seal-
ing or stop-leak compounds in boiler
system. Damage to system components
can result.
•
For pH conditions outside 7.0 to 8.5 range or un-
usually 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 skim-
ming until discharge is clear.
4. While boiler is warm, but not hot, drain boiler
through drain valve.

SERVICE TECHNICIAN ONLY — read and follow completely.
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 "Burner
adjustments" on page 37.
5. Check boiler and system piping for leaks. See "Tips
for steam systems."
6. Inspect breeching and venting for proper operation.
Boiler Manual
Follow information below to prevent se-
vere personal injury, death or substantial
property 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,
breeching and burner mounting door are
secured in place. Never burn garbage or
paper in the boiler.
Never leave combustible material around
boiler
A burner nozzle change may be required -
refer to the burner instructions or boiler's
rating label for correct selection.
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 sub-
stantial property damage.
