Primary Water; Freeze Protection; Combustion Air Contamination Prevention - NTI TRX User's Information Manual

B. Primary Water
• Do not attempt to clean the heating system. Call a qualified
service technician for service.
• If you notice any leaks, immediately call a qualified service
technician. Leaks in boiler or piping must be repaired at once.
C. Freeze Protection
WARNING
Closed loops that use glycol as heat transfer fluid must be serviced
periodically. Glycol can break down over time, become acidic, and
attack gaskets and seals in boilers. This can result in property damage,
severe personal injury, or death.
Each glycol manufacturer has different recommendations for
testing and replacement. Do not test glycol quality yourself. Have
your qualified service technician check glycol quality during annual
servicing. If you are unsure when your glycol was last tested, call a
qualified service technician to test and replace glycol, if necessary.
DO NOT shut off the boiler for long periods of time during potentially
freezing conditions. If the boiler must be shut off during potentially
freezing conditions (is not to be used for an extended period of time),
shut down the system and drain it of water. Shut off the gas and cold
water supply valves.
Ensure exposed water pipes are thermally insulated to prevent
damage due to freezing conditions. If the boiler is not to be used for
an extended period of time during freezing conditions, shut down
the system and completely drain the boiler.
If the water pipes should freeze, thaw the pipes with a hair dryer or
other electric heating device. If this does not work, call a qualified
service technician.
D. Combustion Air Contamination Prevention
DANGER
Do not operate the boiler if its combustion air intake is located in or
near one of the areas or in the vicinity of products listed in Table 1.
These areas will always contain hazardous contaminants that can
form strong acids while passing through the burner and vent
system. These acids will corrode the boiler's heat exchanger, burner
components and vent system, resulting in flue gas spillage and/
or water leakage, possible substantial property damage, severe
personal injury, or death. If the boiler combustion air intake is located
in any area likely to cause or contain contamination, or if products
which would contaminate the air cannot be removed, the intake
must be re-piped and terminated to another location.
DO NOT re-pipe ventilation system on your own. Call a qualified
service provider for assistance.
