NTI TRX - During Operation; General Cautionary Statements

Part 2 - Operating Instructions
O. During Operation
1. Check for Gas Leaks
Frequently check the gas pipe and connections for leaks with a
soapy solution. Gas is leaking if air bubbles appear during the test.
Close the gas supply valve and call your gas supplier for inspection.
2. Check Exhaust Vent and Intake Pipe for Proper Ventilation
Ensure there is sufficient ventilation while operating the boiler.
Improper ventilation could result in premature boiler failure. Such
failures ARE NOT covered by boiler warranty.
3. Burn Warning
Take caution when inspecting the boiler and its internal
components, exhaust vent, and/or water pipes. These components
can get extremely hot during operation.
4. Combustibles and Flammable Material Warning
Do not store combustibles or flammable materials in the vicinity of
this boiler. Do not hang anything from the exhaust pipe.
5. Check for Water Leaks
• Do not attempt to clean the heating system. Call a qualified
service technician for service.
• Immediately call a qualified service technician if you notice any
leaks. Leaks in boiler or piping must be repaired at once.
P. General Cautionary Statements
The boiler is protected from malfunctioning by means of internal
checks performed by the electronic microprocessor PCB, which stops
the boiler from operating if necessary. In the event of the boiler being
shut off in this manner, a code appears on the display which refers to
the type of shut-off and the reason behind it.
There are two types of shut-off:
1. Blocking Error
A blocking error means the boiler will restart
automatically as soon as the problem which
caused the error clears or is removed; the error
is indicated by the « » symbol which
appears on the display followed by the error code.
For example, if the boiler indicates a 110 error
code, the error will clear automatically when the
CH temperature decreases. The boiler will restart
and operate normally.
NOTE: Contact a qualified service technician if the
error continues to occur.
In the event of Error 108 - Shut-off due to
insufficient water pressure inside the heating
circuit - turn the boiler off. Turn the external
electric power to the OFF position. Shut off the
main gas valve and contact a qualified service
technician to check for any leaks of water.
2. Lockout Error
A lockout error means the boiler does not return to operation after the
error condition goes away. The button must be pressed on the
control panel to restore boiler operation.
If the error condition occurs often contact a qualified service technician.

WARNING
WARNING
After any repair of the gas pipeline or replacement of the gas
regulator, call a qualified service technician to observe the installation
and replacement before restoring power to the boiler. Failure to do
so could result in a fire or explosion, substantial property damage,
severe personal injury, or death.
DO NOT use this boiler for any purposes other than those specifically
described by NTI (to provide central heating and domestic hot water).
Using this boiler for unapproved purposes WILL VOID the warranty,
and could result in substantial property damage, serious personal
injury, or death.
Exhaust gas entering the living space can cause carbon monoxide
poisoning. If exhaust gas should leak into the living space:
• Shut down the boiler.
• Close the gas valve.
• Open windows for ventilation.
• Ensure the CO detectors are operating properly.
Immediately call a qualied service technician to inspect the boiler
and exhaust vent pipe. Any damages to the exhaust vent pipe should
be repaired immediately. Failure to do so could result in a re or
explosion, substantial property damage, severe personal injury, or
death.
WARNING
Storing flammable or combustible materials near this boiler could
result in a fire or explosion, substantial property damage, severe
personal injury, or death.
