fired water boiler
STOP!! — Read before proceeding
Have this boiler serviced/
inspected by a qualified
service technician, at least
annually.
Failure to comply with the above
could result in severe personal
injury, death or substantial prop-
erty damage.
When calling or writing about the
boiler— Please have the boiler
model number from the boiler
rating label and the CP number
from the boiler cabinet.
Boiler service and maintenance —
To avoid electric shock, disconnect electrical
•
supply before performing maintenance.
To avoid severe burns, allow boiler to cool before
•
performing maintenance.
You must maintain the boiler as outlined in the
•
manual and have the boiler started up and ser-
viced at least annually by a qualified ser-
vice technician to ensure boiler/system reliability.
Boiler operation —
•
Do not block flow of combustion or ventilation air to
boiler. This boiler is equipped with a control which
will automatically shut down the boiler should air or
vent be blocked. If vent or air blockage is easily ac-
cessible and removable, remove it. The boiler should
attempt to restart within an hour. If blockage is not
obvious or cannot be removed, have the boiler and
system checked by a qualified service technician.
Combustion air —
DO NOT obstruct the combustion air intake or
•
expose the air intake to corrosive chemicals
(see next page).
Part number 550-142-123/0513
— User's information Manual
Failure to adhere to the guidelines on this page can result in severe personal
injury, death or substantial property damage.
• Should overheating occur or gas supply fail
to shut off, DO NOT turn off or disconnect electrical
supply to circulator. Instead, shut off the gas supply at
a location external to the appliance.
• Do not use this boiler if any part has been
under water. Immediately call a qualified service
technician to inspect the boiler and to replace any part
of the control system and any gas control that has been
under water.
Carbon monoxide detector —
•
A carbon monoxide detector that is wired on the
same electrical circuit as the boiler is strongly recom-
mended.
Boiler water —
•
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.
Leaks in boiler or piping must be repaired
•
at once to prevent make-up water. Use this
boiler ONLY in a closed-loop system. Con-
tinual fresh make-up water will reduce boiler life.
Mineral buildup in heat exchangers reduces heat
transfer, overheats the materials, and causes failure.
Addition of oxygen carried in by make-up water can
cause internal corrosion.
Do not add cold water to hot boiler. Thermal
•
shock can cause heat exchanger to crack.
Freeze protection fluids —
•
NEVER use automotive or standard glycol antifreeze.
Use only freeze-protection fluids made for hydronic
systems. Follow all guidelines given by the antifreeze
manufacturer. Thoroughly clean and flush any re-
placement boiler system that has used glycol before
installing the new boiler.
