WARNING
DO NOT USE THIS BOILER IF ANY PART HAS BEEN SUBMERGED IN
WATER. Immediately call a qualified service technician. The boiler
MUST BE replaced if it has been submerged. Attempting to operate
a boiler that has been submerged could create numerous harmful
conditions, such as a potential gas leakage causing a fire and/
or explosion, or the release of mold, bacteria, or other harmful
particulates into the air. Operating a previously submerged boiler
could result in property damage, severe personal injury, or death.
NOTE: Boiler damage due to flood or submersion is considered an
Act of God, and IS NOT covered under product warranty.
WARNING
DO NOT alter or modify the appliance or appliance controls.
Altering any NTI boiler with parts not manufactured by NTI WILL
INSTANTLY VOID the boiler warranty and could result in property
damage, personal injury, or death.
CAUTION
Due to the low water content of the boiler, improper sizing of the
boiler with regard to heating system load will result in excessive
cycling and accelerated component failure. DO NOT under or
oversize the boiler to the system. Modular boiler installations
greatly reduce the likelihood of boiler oversizing. NTI DOES NOT
warrant failures caused by improperly sized boiler applications.
High heat sources (sources generating heat 100
greater, such as stove pipes, space heaters, etc.) may damage
plastic components of the boiler as well as plastic vent pipe
materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8" from high heat
sources. Observe heat source manufacturer instructions, as well
as local, state, provincial, and national codes, laws, regulations
and ordinances when installing this boiler and related components
near high heat sources.
Do not use this boiler for anything other than its intended purpose
(as described in this manual). Doing so could result in property
damage and WILL VOID product warranty.
NOTICE
This appliance is equipped with a three prong plug. It should only be
plugged directly into a properly grounded three prong receptacle.
DO NOT remove the ground plug from the plug.
This appliance provides an overheat shutdown limit. In the event the
appliance water temperature exceeds the setpoint of the control
limit, the cutoff will trip and the appliance will shut down. Certain
local codes require additional temperature limits. In addition,
certain types of systems may operate at temperatures below the
minimum setpoint of the limit provided with the appliance. Contact
the manufacturer for additional overheat controls.
B. Improper Combustion
Do not obstruct the flow of combustion and ventilating air.
Adequate air is necessary for safe operation. Failure to keep the
exhaust vent and combustion air intake clear of ice, snow, or other
debris could result in property damage, serious personal injury, or
death.
C. Gas
Should overheating occur or gas supply fail to shut off, turn off the
manual gas control valve to the boiler.
D. When Servicing the Boiler
Be sure to disconnect electrical power before opening boiler
cabinet or performing service. Label all wires while performing
service to ensure proper re-wiring of the appliance. Wiring errors
can cause improper or dangerous operation. Failure to do so could
result in electrical shock, improper boiler or system operation,
property damage, serious personal injury, or death.
•
To avoid electric shock, disconnect electrical supply before
performing maintenance.
•
To avoid severe burns, allow boiler and associated equipment
to cool before servicing.
•
Do not use petroleum-based cleaning or sealing compounds
o

F / 37
C or
in boiler system. Gaskets and seals in the system may be
damaged, possibly resulting in substantial property damage.
•
Do not use "homemade cures" or "boiler patent medicines".
Substantial property damage, damage to boiler, and/or serious
personal injury may result.
•
Always verify proper operation after servicing the boiler.
NOTE: When inquiring about service or troubleshooting, reference the
model and serial numbers from the boiler rating label.
E. Boiler System
•
Thoroughly flush the system (without the boiler connected)
to remove sediment. The high-efficiency heat exchanger can
be damaged by build-up or corrosion due to sediment. The
manufacturer recommends a suction strainer in this type of
system.
•
Do not use petroleum-based cleaning or sealing compounds
in boiler system. Gaskets and seals in the system may be
damaged, possibly resulting in substantial property damage.
•
Do not use "homemade cures" or "boiler patent medicines".
Substantial property damage, damage to the boiler, and/or
serious personal injury may result.
•
Continual fresh make-up water will reduce boiler life. Mineral
buildup in the heat exchanger reduces heat transfer, overheats
the stainless steel heat exchanger, and causes failure. Addition
of oxygen from make-up water can cause internal corrosion
in system components. Leaks in the boiler or piping must be
repaired at once.
NOTE: DO NOT add cold make up water to the system when the
boiler is hot. Thermal shock can potentially cause cracks in the heat
exchanger. Such damage IS NOT covered by warranty.
