OIL-FIRED NATURAL DRAFT STEAM BOILER — SERIES 3 —
Boiler Manual
HOMEOWNER and SERVICE TECHNICIAN — read and follow completely.
Follow instructions below to prevent severe personal
injury, death or substantial property damage:
•
To avoid electric shock, disconnect electrical supply to burner
service switch and additional external switches before perform-
ing 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
Tips for water systems —
•
Check boiler and system piping for leaks. Continual makeup water
will reduce boiler life. Minerals can build up in sections, reduc-
ing 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 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°F.
❏
Local codes may require back-flow preventer or actual discon-
nect 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 instructions.
❏
Do not add cold water to hot boiler. Thermal shock can cause
sections to crack.
