For Your Safety
Follow instructions below to
prevent severe personal injury, death or substan-
tial 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 combus-
tion 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.
DO NOT TAMPER WITH UNIT OR CONTROLS.
Always follow specific instructions when
starting up boiler or performing routine
maintenance or service.

Tips for water 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 recom-
mended 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 systems.
Damage to system components can result,
causing property damage.
Boiler water pH 7.0 to 8.5 is recommended.
For pH conditions outside 7.0 to 8.5 range or
unusually hard water areas (above 7 grains
hardness), consult local water treatment
company.
When using antifreeze:
- Use antifreeze especially made for
hydronic systems. Inhibited propylene
glycol is recommended.
Do not use automotive,
ethylene glycol, undiluted or petroleum-
based antifreeze. Severe personal injury,
death or substantial property damage can
result.
- 50% solution provides protection to about
-30
0
F.
- Local codes may require back-flow
preventer or actual disconnect from city
water supply.
- Determine quantity according to system
water content. Boiler water content is
listed on back cover of Boiler Manual.
Percent of solution will affect sizing of
heat distribution units, circulator and
expansion tank.
- Follow antifreeze manufacturer's instruc-
tions.
Do not add cold water to hot boiler. Thermal
shock can cause sections to crack.
CAUTION
Follow instructions below to
prevent severe personal injury, death or substan-
tial property damage:
To avoid electric shock, disconnect electrical
supply to burner service switch and additional
external switches before performing service.
To avoid severe burns, allow boiler to cool
before performing service.
Do not block flow of combustion or ventilation
air to boiler.
Boiler must be connected to a flue with
sufficient draft at all times to assure proper
operation.
Do not use this boiler if any part has been
under water. Electrical and mechanical
failures may cause electric shock and fire
risks. Immediately call a qualified service
technician to inspect chimney or vent,
boiler and burner. Have the boiler flueways
cleaned and have the following replaced:
— all electrical and mechanical controls
— electrical wiring
— oil burner and controls
— insulation and chamber lining
