Startup procedure
Follow information below to prevent
severe personal injury, death or sub-
stantial property damage:
•
Do not use gasoline crankcase drain-
ings 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 breeching
and burner mounting door are secured
in place.
•
Never burn garbage or paper in the
boiler.
•
Never leave combustible material
around the boiler.
When using antifreeze
automotive, ethylene glycol, undiluted
or petroleum-based antifreeze. Severe
personal injury, death or substantial
property damage can result.
•
Use antifreeze especially made for
hydronic systems. Inhibited propylene
glycol is recommended.
•
50% solution provides protection to
about -30 °F. Do not exceed 50% mix-
ture.
•
Local codes may require back-flow
preventer or actual disconnect from
city water supply.
•
Determine quantity according to sys-
tem water content. Boiler water con-
tent is listed on back cover of manual.
Percent of solution will affect sizing of
heat distribution units, circulator and
expansion tank.
•
Follow antifreeze manufacturer's in-
structions.
Fill the system:
1. Close manual and automatic air vents and boiler
drain cock.
2. Fill to correct system pressure. Correct pressure will
vary with each installation. Normal cold water fi ll
pressure for residential systems is 12 psig. Boiler
water pH 7.0 to 8.5 is recommended.
3. Open automatic air vent one turn.
4. Open other vents.
a. Starting on the lowest fl oor, open air vents one at a
time until water squirts out. Close vent.
b. Repeat with remaining vents.
5. Refi ll to correct pressure.

•
To place in operation:
1. Verify boiler is fi lled with water.
2. Open burner mounting door and verify burner door insulation sections
— Do not use
3. Verify burner mounting door is closed tightly and burner wiring har-
4. Factory burner adjustment and settings may not be suitable for specifi c
5. To observe the fl ame, loosen the observation port center bolt. Rotate
5. Vent air from system. Repeat steps 4 and 5 under "Fill the system." Air
6. Check boiler and system piping for leaks. See "Tips for water systems."
7. Inspect breeching and venting for proper operation.
Follow additional instructions:
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 com-
pounds in boiler systems. 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.

the center bolt. When fi nished viewing, loosen the center bolt. Rotate
the observation port so the glass is at the 12:00 position. Then retighten
the bolt. This will prevent soot from depositing on the glass.

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