WATER
BOILER
— Boiler Manual
Please read before proceeding
Read all instructions —
•
Read all instructions, including this manual, the burner
manual and any related supplements. Perform steps in
the order given. Failure to comply could result in severe
personal injury, death or substantial property damage.
When servicing boiler —
•
To avoid electric shock, disconnect electrical supply before
performing maintenance.
•
To avoid severe burns, allow boiler to cool before perform-
ing maintenance.
Boiler operation —
• Do not block fl ow of combustion or ventilation air to
burner.
•
Should overheating occur or fuel supply fail to shut off, do
not turn off or disconnect electrical supply to circulator.
Instead, shut off the fuel supply at a location external to
the appliance.
• Do not use this boiler if any part has been under water.
Electrical and mechanical failures may cause electric
shock and fi re risks. Immediately inspect chimney or vent,
boiler, burner and controls. Clean the boiler fl ueways and
replace all electrical and mechanical controls; all electrical
wiring; oil burner and controls; insulation and chamber
lining.
Boiler fi ring rate —
•
Do not reduce the fi ring rate of the boiler. Use only the oil
nozzle size specifi ed. Reduced input will cause condensa-
tion in the boiler and vent piping.
Ceramic fi ber materials —
•
The boiler contains ceramic fi ber materials. Use care
when handling these materials per instructions on
page 26 of this manual. Failure to comply could result
in severe personal injury.
Boiler water —
• Thoroughly
fl ush the system (without boiler con-
nected) to remove sediment. The boiler heat exchanger
can be damaged by build-up or corrosion due to sedi-
ment.
• Do not use petroleum-based cleaning or sealing
compounds in boiler system. Gaskets and seals in the
system may be damaged. This can result in substantial
property damage.
•
Do not use “homemade cures” or “boiler patent medi-
cines.” Serious damage to boiler, personnel and/or
property may result.
• Continual fresh make-up water will reduce boiler
life. Mineral buildup in boiler sections reduces heat
transfer, overheats the sections, and causes failure.
Addition of oxygen carried in by make-up water can
cause internal corrosion. Leaks in boiler or piping
must be repaired at once to prevent make-up water.
• Do not add cold water to hot boiler. Thermal shock
can cause heat exchanger to crack.
Freeze protection fl uids —
•
When using antifreeze — Do not use automotive, eth-
ylene glycol, undiluted or petroleum-based antifreeze.
See the WARNING on page 23 for more information.
Follow the guidelines below to prevent possible severe personal injury, death or substantial property damage.

Fuel
• Do not use crankcase drainings or any oil containing
gasoline. See burner manual for proper fuel oil.
• Never burn garbage or paper in the boiler. Never leave
combustible material around boiler.
Do not tamper with burner/controls
• Always follow specifi c instructions when starting up
boiler or performing routine maintenance or service.
Do not start burner if:
• Do not attempt to start burner when excess oil has ac-
cumulated in combustion chamber, when unit is full of
vapor, or when combustion chamber is very hot.
•
Do not start burner unless breeching and burner mount-
ing door are secured in place.
