NFORMATION
Manual
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.
•
Should overheating of boiler occur or gas sup-
ply 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 qualifi ed service
technician to inspect the boiler and to replace any part
of the control system and any gas control that has been
under water.
Failure to adhere to the guidelines on this page can result in severe
personal injury, death or substantial property damage
.
Boiler service and maintenance —
• To avoid electric shock,
interrupt 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 qualifi ed ser-
vice technician
to ensure boiler/system reliability.
Boiler operation —
• Do not block fl ow 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 qualifi ed service technician.
Combustion air —
•
DO NOT obstruct the combustion air intake or
expose the air intake to corrosive chemicals
(see next page).
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 fl uids —
• NEVER use automotive or standard glycol antifreeze.
Use only freeze-protection fl uids made for hydronic
systems. Follow all guidelines given by the antifreeze
manufacturer. Thoroughly clean and fl ush any re-
placement boiler system that has used glycol before
installing the new boiler.
